Title: NEW KomputerBay *1050x* 128 GB Card
Post by: Kraemer on July 03, 2013, 08:54:22 AM
I've been talkiing with the guys at KomputerBay and we decided to do a test with their newest 1050x 128Gb card.
All I can say is wow--  It ate up over 35000 frames without skipping one frame!  35000 frames at 24 fps is 00:24:18:08 

I'll admit the camera did get a bit warm, the card was on the verge of hot, but as soon as it came out from the camera it cooled off in about 20 seconds.  The Quality is really noticeable in this test.  I rolled on about 6 different shots and compared the All-I compression with the RAW--I also shot some using the 3x Crop mode.

I shot this at 1920 x 1080.   Using a mac and raw magic software, I batched these shots and flipped them all into after effects.  Very little was done there.  Rendered Apple Pro Res 1920x1080, then downconverted that to 1280x720 for vimeo.  The original Pro-Res 1920 x 1080 the differences are more striking.  I wasn't able to record beyond 1920 x 1080 in size however.  It took about an hour to flip the raw file to a series of .dngs.

See it here: 

The differences on between the original canon All-I compression and the ML RAW are amazing.  Huge files, but the KomputerBay 1050x Card did a superior job rolling along.  Here's the benchmark tests from that new 1050x card (compared with the 64 Gb 1000x ):

For some reason the speeds at the beginning of the test were slower..not sure why..but
--It was nice being able to roll continuously with no problems for over 30,000 frames, thats 24 minutes!

Title: Re: NEW KomputerBay *1050x* 128 GB Card
Post by: HugoFilipe on July 04, 2013, 10:42:24 PM
Since it only does 1080 at 24fps, probably bits slower than the 64GB version.
How about 48p, whats the max resolution? Compared to the 64GB.

What about warm up? Does it need to warm up?

These cards in my tests so far are fabulous no dropped frames at 1920x1080 for 10 minutes of continuous shooting, June 27th build, 5D Mark 3 Global draw turned off.   So thus far it's been no dropped frames with Transcend 64 GB 1000x and now with KomputerBay 128 1050x,

I guess these 1050x cards will eliminate any problems with any inconsistencies with shooting continuous 1080p RAW, like the 1000x cards have.

Still no 25fps 1920x1080 tryout? Come onHow hard can it be??
Would the 1000x specs been right from the start like most 64gb cards we wouldn,t be needing any 1050x cards to begin with, don,t you think?

Well, I don,t know what you actually mean by that but if people already have a card and manage to record 24fps on their 5d mark 3, it,s actually not that hard to set the camera to 25fps and do a little testing. A little help

What I mean is that you seem to be yelling at someone else for not having time to test it.  If you're that upset/anxious, you should buy one and test it.

This is a good question. If the 1050x card (or any 1000x card, for that matter) is capable of recording 2+ minute clips at this resolution, the potential for organic looking 4k output is more likely. I've messed around with uprezzing a few 5D3 raw 1080p stills to 4k in AE and have been mildly pleased with the results on my friend's 65" Sony display.

I could be wrong, but I recall reading something about ml not being able to install on cards bigger than 32gigs. do you have a sd slot on there in addition to the cf slot?

Erous, did you solve your problem?

So, people, are these 1050x cards reliable (The 1000x seems to be not)...

I'm about to buy one, which one is the most safe for a 1080p at 24fps Raw, Lexar 64gb 1000x or Komputerbay 128gb 1050x?

I saw the benchmarks in the first post on this thread, results didn't seem to be really good...

What do you guys think?

I am waiting till 2 weeks for the 1050x card to arrive. I tested 4x 128gb 1000x cards from Komputerbay before but they are all insufficient for 1080p. I have 2x 64gb 1000x Komputerbay and they are good for 1080p.

Problem still alive...I shoot with 5DII, so no SD slot! No exFat possibilities.
I tried all solutions! Last solution is send back to Komputerbay. :/
Komputerbay's fiability is the lotery.
However if somebody have a solution? :)

Someone lay this out to me like I'm a 5th grader. Is this card guaranteed to be faster than the lottery of 64gb 1000x cards everyones been playing with? I'm not entirely interested in ordering/returning cards until I get one that writes fast enough. Has this card sorted that out?

My komputerbay 128gig 1050x udma 7arrived today, promptly tested it! And unfortunately IT DID NOT WORK.

Cannot be formated by 2 cameras, 5d2 and 7d. cant be recognized by my PC as well.

I have a proven Lexar 1000x 32 gig for several weeks now and never failed me.

I wanted to try this out since there is one reviewer here in ML that tried it.

So I filled out my return form and sent back my card.



edit: in touch with their tech support to find what caused problem and find solution. See my posts below for updates.

My 32GB 1000x from komputerbay works perfectly out of the box. I've heard many others recommending the 64gb 1000x. The failure rate seems to be lower on these cards (1000x) possibly?

The lower the size, the better chance it will perform at higher resolutions.

Given all the reports here and in other forums of hit and miss, the ratio is at 50-50 chance of working and non-working.
I do not not think it is prudent for me and others to recommend this brand to a friend or a stranger.

I have tried the 1000x 64 gig version of komputerbay for a few minutes only since it was my friend's card, mine is a lexar, and it was working. I could not say it would stay that way longer than a lexar or more proven brands.

the 1000x 64 gigs seem to have a higher percentage of "good feedback" but this thread is about the 1050X so my report for that version is a big thumbs down.

I am talking with Komputerbay techsupport right now to isolate this problem. For now for those with UDMA7 1050x cards have a problem with older non UDMA7 card readers. If you have this hold on for my updates and DO NOT plug it into older cf card reader as it WILL CAUSE CORRUPTION ON THE CARD.

I'll update this post in a few hours as tech support will also be calling those who emailed and contacted them so we can isolate the problem.
Title: Re: NEW KomputerBay *1050x* 128 GB Card
Post by: ted ramasola on July 23, 2013, 08:55:43 PM
One of the issues in using the new 1050x cf cards is using non UDMA7 card readers,

According to Chet at techsupport, non UDMA7 has the potential to corrupt the new 1050x cards. His advise to those who have purchased this fast cf cards is DO NOT INSERT THEM TO USB 2.0 CARD READERS.

UDMA7 card readers for USB 3.0 should be used as the new cards use a different voltage. The cards would protect itself and give you "card is write protected" message when an incompatible card reader with a different chipset is used. This will prevent further damage to the CF card.

They are sending over 2 128gig CF cards which I will test for the mkII, one is a new 1000X from a new manufacturing batch which they said has no more issues as the early ones and another 1050x CF which hopefully I can get to work with a compatible CF card reader.

I will update this when my tests will be done.

So far, one thing goes well for komputerbay for me, and that is a great and responsive technical support BASED IN THE U.S. that will resolve the issues you have with their product. Stay tuned.

Hello everybody,

@ Ted, glad to hear that Komputerbay kind of "care" about their customers.. About the "new 1000x ", when will this card be available? And how can we recognize it compare to the old 1000x? (the price maybe)..

I didn't buy my cf cards yet (and i have to do it really soon), so i hope that your tests (and other's) will show us that these cards are reliable..

Have a nice day all !!

Hello Folks,

We have finally been given permission to talk on public forums on a trial basis. Please direct questions to techsupport@komputerbay.com as we will not be able to reply back to the forums on a regular basis.

The 1050X is the fastest car that we have launched yet and has been confirmed to work on the 5DM3 for ML. You can achieve 1920X1080 @ 25fps without a problem. These are 5~9% faster than the 64GB 1000X.

We have seen some incompatibility with the 5DM2 (limited to FAT32 and bandwidth bottleneck of 67~72MB/s). We are working on this to see if these are users errors/camera limitation/card limitation. We will be talking to Ted later today to see if we can fix this issue. We reached out to 6 other users yesterday but they were not reachable.

We did reach out to 5DM3 users (this camera can use exFAT and can write 100MB/s) and some have already confirmed that they have used the card successfully.

The newer 1000X 128GB are the ones that Amazon has instock in USA. Basically anything that shipped from USA since this past Friday is the newer (V2) 128GB 1000X cards. They are just as fast as the 64GB 1000X cards. They will be in Europe by the 1st week of August.

Rumors: These are not QC failed Lexar cards. Some of our cards are made with the same components.

Fast/Slow cards: We have not been able to identify fast/slow cards yet. There is a card warmup required for some cards for them to work at their optimum speed (CF card design). Once they reach the optimum temp. - they work fine.

The best way to benchmark a card is on a UDMA 7 compatible USB 3.0 High Speed reader. We do not recommend firewire/USB 2.0/PCI Express as there are a lot of cases where people have lost their .raw files while transferring files. We recommend using CrystalDiskMark @ 4GB for PC and Blackmagic for Mac for speedtest. Please do not use h2testw for speedtest as their software has a bandwidth limitation however it is a good test for capacity checking.

Regards,

Tech Support

@KB Techsupport: Nice to see a company interacting directly with users (and potential users). This note is meant more for your sales team, but I'm hoping that you'll be able to relay the message. Please consider lowering the shipping rates to Asia -- it currently costs almost as much as the card itself. Thanks.

Sales team claims that the only method they will use to send to Asia is Fedex which is anywhere from US$ 50~100.00. We have quite a few customers using the eBay global ship program to send goods to Australia/Canada/NZ. If you have suggestions - you can email them at sales@komputerbay.com.

Out of curiosity, KB tech support, if the internals aren't broken lexars, what internals are the komputerbay cards sporting?

Also on the description of the 128GB 1050x it says it's write speed is the same as the 1000x cards. The only difference is that the read speed is faster. Is this true?

Thanks for giving support.

I just made the switch to Canon 5d mkIII just to use this hack. Been a happy Magic Lantern user since 2 years with my mkII

This new 1050x CF card product is extremly cool. Thanks for making this happen.
Also cool that KomputerBay talks to the customers!
Probably we could come around the USB2.0 card reader problem, when using a splitcable for USB that gives the device more power. I use this for example on my 3rd party CDrom drive attached to Macbook Air.

I'm currently trying to figure out how to get a proper reverse charge invoice when buying from amazon (Amazon would compute the right VAT but buying from a dealer registred with Amazon results in the wrong VAT making the product 19% more expensive).

Hope that my order works out soon.

Will post some tests as soon as I get 2 of the 128GB version cards.

128GB 1000X V2 (basically anything that was shipped from USA since last week, UK since this week and DE/Fr/ES/IT this week is all V2)

is: 90~100MB/s Write and 150MB/s Read

128GB 1050X is 100~110MB/s Write and 160MB/s Read



We are looking at 120MB/s Write speeds cards (1200X) early next month on a trial basis. Mass production will be looked into once these pass the tests.

Thank you Komputer Bay Support for your clear answers as well. I bought a Komputer Bay 128 GB 1000X CF card last November and it still functions great. I guess mine was one of the good ones because when writing RAW video to my 5D3, it averages about 97-98 mbs. So I'll be happy to pick up a Komputer Bay 128 GB 1050X soon.

Out of curiosity, KB tech support, if the internals aren't broken lexars, what internals are the komputerbay cards sporting?

>>The main component which is Micron NAND. Some of our cards carry the same exact Micron NAND.

Also on the description of the 128GB 1050x it says it's write speed is the same as the 1000x cards. The only difference is that the read speed is faster. Is this true?

128GB 1000X V2 (basically anything that was shipped from USA since last week, UK since this week and DE/Fr/ES/IT this week is all V2)

is: 90~100MB/s Write and 150MB/s Read

128GB 1050X is 100~110MB/s Write and 160MB/s Read



We are looking at 120MB/s Write speeds cards (1200X) early next month on a trial basis. Mass production will be looked into once these pass the tests.

Thanks for the response! One more question though:

"The main component which is Micron NAND. Some of our cards carry the same exact Micron NAND."

When you say "Some of our cards carry the same exact Micron NAND.", which cards does Komputerbay offer that contain this chip?

Wow, this progress would be absolutly amazing!

I'm eager to order 3 of those 1200X ones.
I hope they will come before November to match our production.

This speed really has enough headroom to make dropped frames something of the past.. probably also good for a suitable 1080p30 and a 720p50 option.

For some reason the speeds at the beginning of the test were slower..not sure why..but
--It was nice being able to roll continuously with no problems for over 30,000 frames, thats 24 minutes!
What I have heard a warmup of 1,5 - 2 GB makes the 1000x cards somewhat faster or reliable.
This might be a myth. However it could be a possible explanation.

Anyone have any advice for 50D and MKII users? We don't have an SD slot to run / install ML from...

Buy the cheapest CF card you can find. Speed and capacity is irrelevant as you're only installing from it. You should be able to pick one up on ebay for under 5$ or borrow one from somewhere. You only need to to install once to set the bootflag. Then you can use your KB card.

Get a cheap 4gb CF card unlock the bootloader on that and then you'll be golden.

Thanks for responding.

I have a few CF cards all with proper ML installations.

So my procedure would be:

1. Install Fresh ML on another CF card.
2. Eject Card
3. Plug into computer card reader and copy files to PC.
4. Eject other card, plug in KB card, copy files into root directory.
5. Make card active via EOScard / MacBoot.
6. Eject Card - replace CF inside camera.
7. Turn on and *hopefully* ML loads

Does this sound right?

You don't need to move files at all... just move the magic lantern root from the RAR to your bigger CF card after you installed it and make sure AUTOEXEC.bin is in the bigger card so it can boot. Then EOSCARD it and done.

Still won't work. The 5DmkII can't see the .FIR file on the 128 gig 1000x or 1050x card.

That method you mention is not a problem with 32 or 64 gig 1000x cards.
Title: Re: NEW KomputerBay *1050x* 128 GB Card
Post by: alvink on July 25, 2013, 07:05:45 AM
I just finished doing some testing on my New KomputerBay 1050x 128GB Card.

A little disappointed as I have read others having flawless results. I could not obtain consistent Continous results at 1920x1080 24fps with global draw on or off. (Drop frames would occur randomly, some times 2 frames into the recording or some times 1000 frames.)

Here are my settings.

- Formatted CF card to Exfat
- Running ML off 32gb SD Card 95mb speed.
- Using ML v2.3 2013-July-17- 5D3 1.13
- Warmed up the card with 1GB files
- Tried recording at 1920x1080 24fps
- Tried Global Draw on & off
- Tried Memory hack On & Off

Here are some results which I got.

1920x1080 24fps Global Draw OFF Test 1

(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2F1920x1080-24p-Global-Draw-OFF-Benchmarks.jpg&hash=73ed3523265510d5a77f35ff84f7d949)

1920x1080 24fps Global Draw OFF Test 2

(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2F1920x1080-24p-Global-Draw-OFF-Benchmarks_T2.jpg&hash=a3f2a9863c1bd890623d8cf72078a336)

1920x1080 24fps Global Draw ON Test 1

(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2F1920x1080-24p-Global-Draw-ON-Benchmarks.jpg&hash=66e39cfdcf1d3719a500593d5421dccc)

The results were a downer, and the card was not consistent in performance at all.  (As shown above the results from Global Draw On is actually better than Global Off....weird...)   (Some times it would give me the green "Good to go" record setting approval at the bottom along with all the record dimensions and mbs per frame at 1920x1080, but when I record it would fail after few hundred frames.  So times it even fails at 3 fps... I have never gotten past 3000 frames at 1920x1080 with this card.)  I consider this as a fail in recording 1920x1080 continuous.

Finding a stable setting for this card.

Bumping down the Ratio:

I started to bump the ratio down from 16:9 to 1.85:1 and so on until 2.35:1

Unfortunately for me it was only some what stable at 2.35:1 .   Recorded at 1920*818  18049 frames. (that is 47.5GB) (Consistently recored 70mb per frame.) (I consider this to be a pass as I don't shoot documentaries...)

Bumping down the resolution:

After testing the ratio setting I put it back at 1920x1080 and started to test the resolution. 1920x1080 to 1856x1044 to 1728x972

Once again it was only some what stable at 1728x972 Recorded at 1728*972  18278 frames. (that is 50GB) (Consistently recored 69.8mb per frames)

(I consider this to be a pass as I don't shoot documentaries...)

Over View:

Over all the card itself for normal use is excellent, It can handle 6fps burst raw + jpg easily as well as recording video in h264.  As for shooting raw video I was hoping it could do stable continuous 1920x1080 @ 24fps and maybe even 1920x1080 @ 30fps. So I'm a disappointed that this card can not shoot at those settings.  I will look at the 64gb 1000x as a temp solution while I wait for their 1200x version to be release in  a month or so.

I hope the information helps and if anyone can recommend me proper settings to make this card work at 1920x1080 then please contact me.

(I would rather have this card work than to send it back.)

I can confirm that Lexar 1000x can do 1080P at 30FPS (32GB version). If swapping cards out is not a problem for you (I have a small Thinkpad and external) for the field, then go for it.

Woh it can do 1920x1080 @ 30fps for the full 32gb?  Hum if that's the case then the 64gb might be worth it. (dont know why but it seems that 32gb and 128gb aren't as good as 64gb even at the same 1000x.)

Any one else have 64gb 1000x cards that can do 1920x1080 @30 without any drop frames?

I made a video on how I'm testing the 128gb 1050x card.

Komputerbay tech support ran through a CrytalDiskMark test with me and we both got similar results 129mb read and 96mb write, from a 4000mb test.  They said that my card should be able to do 1920x1080 @ 24fps continuous no problem...  but I'm still getting drop frames.

He also suggested that I clear my buffer for my camera before recording.... (how do I clear my buffer..besides waiting for the orange light to stop blinking.)  (Side note KomputerBay was very quick in responding to my questions.  Thumbs up to their Tech Support!!)

Anyone got suggestions for the camera settings?

Hi Nate,
Thanks for sharing your results, they look amazing!  That is how all 1050x Komputerbay cards should work. No warm up required and just start recording.

May I know what all your settings are so that I can copy your settings and see if I can get my card to work like that.

Thanks,

 UPDATE:

So after talking to the tech support, they have advised me to keep the drop frames option off and allow the camera to record full 128gb.

Here are some stills taken through out the process.
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2FSAM_0061.jpg&hash=98638b401cc6534ea9f680da963966b7)
First Drop Frame at 3383 (1.5GB)  - 93.3MB/S

At 12788 frame (44GB) the MB/S dropped alot (4.8 mb/s) but still only at 28 drop frames...(Weird)
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2FSAM_0071.jpg&hash=c9f66f9fadcae700cd4ea92078744c4e)
At 32641 frame (112GB) the MB/S came back up a little (23.9 mb/s) and the drop frame is still at 28...(Very Weird)
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2FSAM_0076.jpg&hash=4150737d880729703b2ac3fc83ac6799)
At 35161 frame (121GB) the MB/S was at (28.5mb/s) and the drop frames went up to 299.
 Bench Mark Test:

Bench Mark test, after recording the 128gb and deleting the file. (The card is very warm at this point.)
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.alvinkeung.com%2Fwp-content%2Fuploads%2F2013%2F07%2Fbench-mark-after-128gb-write.jpg&hash=fe88b5b1f251ef4d5d0d7b4834cf4c48)
Results were very disappointing...

Another Bench mark test after dumping 2 more 50GB recordings.  This is as warm as it gets...

Results are still no good....  To be honest I don't believe in a product which requires you to WARM up the card before shooting.....
Other user's Bench Mark:

Here is a fellow KomputerBay 128gb 1050x card user.  He said he bench-marked this from a cold boot..(He even had Global Draw: ON!!!)

I will consult with KomputerBay with my results as they said my card does not have a problem....

More updates coming up.

@alvink,

For the mkIII the Magic lantern is NOT in your CF card but It is in the SD card, is that correct?

I ask because sadly for the 5DmkII we CANNOT use these high capacity cards since we cant bootflag it.

I have both 1000x and 1050X for testing but we cant get the 5D to see the .fir files, even if we use EOScard.

Just wanted to throw in my two cents. I ordered two of these the day they became available on Amazon.

Both cards are able to record ~24 minutes/full card at 1920x1080/24fps with no drop frames on the 5Dmk3. I also do not have to turn on any memory hacks or slow down Canon menus, and was able to keep Global Draw with live waveform monitor on (I don't use anything else)

Obviously, not everyone is getting these results, so try at your own risk and use your credit card instead of cash/debit card so you don't tie up your cash on trying products that you might have to send back. The inconsistency doesn't surprise me since I wasn't able to record more than 30-60 seconds at a time with the 1000x cards (I tried 3) when other people seem to be having much better results with them.

Actually, one more caveat that I found:

When the cards are formatted in camera in FAT, I am only able to record to about 8:30 minutes. The files would not span past 10 pieces. (The last one ends with 09) This is very consistent.

If I format the card as exFAT, then I am able to record one ~128GB file to the card, non-stop.

This basically means I have to remove the card and delete the files on the computer every time I want to empty the cards. If you're using a mac, remember to empty the Trash Can after deleting the files, otherwise the camera will still think it's full.

Thank you for confirming. I am doing some tests with the mkII (2) and you confirm that those using the 128gig CF cards for mkIII (3) are using the SD for ML NOT the CF.

I don't think you can use the 128gig CF to install ML, with 64gig below you could.

The 5dmkII (2) does not support exfat, only fat32, so files are always spanned.  I'll try to see if the 64 gig could exceed 10 spanned files on the mkII.

Can't you use the ML file browser to delete the one 128gb file ?

Yes, but in real life, outside of testing environments, you're going to have a lot of smaller files. Maybe 3-4 on an average narrative style or music video shoot. As far as I can tell, you have to individually delete each file in the ML browser then shut down the camera and restart it back up in order for it to recognize that the card isn't full any more. It's much faster to delete the files then clear the trash can since you have to be on the computer to offload anyway.

I totally could be doing something wrong, but this is the way it works for me right now.

I totally could be doing something wrong, but this is the way it works for me right now.

but your saying that if you are in exfat, the file can be one big 128gb file, can ML file browser delete this single 128gig file? my understanding is, exfat allows you to overcome the 4gig limit. But you can't use in camera format since making your CF exfat was done on your computer not camera, right?

and if you use fat32, which is the default of the camera, your files are spanned over several .R00-.R01 and so on, but since this is camera default you can use canon menu FORMAT to erase the files easily.

But either way, you have to take out your card anyway to offload them. I'm just curious, what works on the mkIII, and also if your in the field and need to delete a wrong take.

I just tested now, the 5DmkII can record on my 64gig continuously til full, this means its 15 separate 4gig files, or to be exact, 3.99 gig each.

Interesting... I wonder what the difference is. I would much rather record to multiple 4GB files and be able to format in-camera than having one file that I have to delete in a special way. The exFAT method doesn't match normal 5D workflows and could cause problems if working with assistants who aren't familiar with ML.

Ya I might have to exchange my card, we'll see what tech support says about my new tests on monday. 

I installed ML on a SD card and I use the CF card for recording. (CF card is formatted to exfat).   From my results, I feel that the card is acting really weird...random spikes in mb/s and when the card is in the middle of the recording of 128gb.. it would drop down to 4 mb/s...and go back up to 28 mb/s..... really weird... as those numbers aren't even the minimum mb/s in recording one frame at that resolution.   Hearing that you guys can record 1920x1080 continuous for 128gb without card warm up makes me feel that my card is gimped.

From my results, I feel that the card is acting really weird...random spikes in mb/s and when the card is in the middle of the recording of 128gb.. it would drop down to 4 mb/s...and go back up to 28 mb/s..... really weird... as those numbers aren't even the minimum mb/s in recording one frame at that resolution.   

Actually, my onscreen readout is doing that too. I think the lowest it goes is 14MB/s though. I don't really understand what's happening there, but it's recording fine so I'm not too worried.

but your saying that if you are in exfat, the file can be one big 128gb file, can ML file browser delete this single 128gig file?

Yes. That's what I'm saying. But it's not useful in real life because you'd almost never record a 24 minute take while shooting raw, and even if you are, it's still harder to delete in camera than the computer. If ML has an exFAT format command, then that would solve it.

I've just been testing my 128gb 1050x card and it's a real dud, I'm going to send it back. I can't get the Magic Lantern files on it so it won't work on its own, others are having that problem too, which means mine will only work on a 5D3 as I can run it off the SD card. Even that doesn't seem to want to work correctly as I can only get it working if I have ML files on the CF card too but it keeps asking me to format one of the cards. When I do get it running it's slower than my 64GB 1000x card which isn't even a very fast instance of that card. The 126GB 1050x hits about 77MB/s-82MB/s and my 64GB hits averages around 85MB/s. The thing is it will be going at say 80MB/s then suddenly skip a frame, I think the speed suddenly drops out as others have mentioned. So, it's either faulty, slow or both. I tried the 128GB 1000x before this and it was slow so I returned it but it at least didn't have these other problems. In the words of Kevin Sorbo - disappointed!

Sorry to hear that you are having the same problem as I am.. ya I would  be recording fine at one point then it would all of a sudden drop frame.  Others have suggested me to install the ML onto the CF card and run it off that as they said that worked for them... So I gave that a try... installed bootable version of ML on to the cf card and tried to boot it.  Had no luck, my 5DMK 3 didn't recognize it for some reason...  So I will be returning the card... still debating if i should exchange for a new one or just return it all together.

I hope your camera is NOT the mkII or I hope the card you ordered is NOT 128gig.

we just tested the 1000x and 1050x sent by komputerbay which they allowed us to test. I also brought it with me to a meetup with HDSLR shooters to test on another camera.

If your using mkII, tough luck, It won't recognize ML on the card.

They work though on th mkIII since ML is running on the SD card NOT the CF.

I have just changed for the 5d mkIII.
Yes, thank you I know about using the SD Card.

My question is rather which card to get because at the moment I do not have any usable card only a Sandisk 600x.
I would love to have a go with a card that gives me no problems until the next generation is out.

If having problems with dropped frames try to set the size for the Photofunctionality to JPG large or even small.

I have mark III and sandisk 600x ( udma7 version) and it performs great. I am getting 1920x1080 24 and 25p continous. its only slighty slower than komputerbay 64 1000x but more predictible IMO. 1920x1080 30p gives about 600frames.

Great insight. 
I'd be really happy if that worked for me as well, but I have the sandisk 600x 32 GB version with UDMA6.
Full resolution is not possible but when I lower the resolution it is a fine card.

Thank you for motivating me, I tried several settings.

Update:
Ok I can do continuous with my card without zero framedrops or problems:
1920x764 p24
1600x900 p25 also with having global draw on
1728x864 p25
1472x828 p30 (for slowmo@70% that one is good to have)
1920x818 p24  worked for a while but at 3127, 3910, 3500 frames I had the 1st framedrop

On the display I can see values between 60,0 Mb/s - 62,9Mb/s.
With the card heated up it almost never goes below 62,2Mb/s
The predicted frames are not far off. All hacks enabled.

Anyways, when I have a faster card that gives me FullHD option then I will use this Sundisk card only for longer Canon H.264 Codec recordings on low DoF shoots.

I got this one (there were no UDMA7 one with the European retailers):
SanDisk CompactFlash Card (CF) Extreme Pro 32GB 90MB/s (SDCFXP-032G-E91/SDCFXP-032G-X46)

Hi,

this is my first post but i'm following the forum since a year or so, i'm more of a hobbyist photographer.

despite bad feedback on the forum about Komputerbay card speed and or reliability, i purchased one 128GB 1050x for testing.
Unfortunately, it turned out that the card was unreadable by both my DSLRs (Canon 5D markIII and markII).
it was only readable on an Lexar dual slot usb3.0 reader on my windows7 Desktop.
the speed was about 90MB WRITE / 120MB/s READ but unusable on the DSLRs

I suspect that the controller was faulty and worked only in CF ATA mode versus Direct IDE mode.

So i wasn't able to perform any testing and will stop trying to work with this brand.

I'm very disappointed, the saving isn't worth the risk to get a defective card and potentially have to deal with all the return hassle..

And in my specific case with the symptoms i had i could have concluded that my brand new 5D3 has some bent pins on the CF slot but fortunately i had an old lexar 800x card that worked perfectly.

I understand that Komputerbay is trying to make the support better but you can't rely on your customers to make the basic QC or QA for you.

My card from amazon.de arrived after a week and I was finally able to test it. The card can perform well at recording 1080p 24 and 25, however there is an issue with heat on the card. After recording a couple of GB (~20gb) the card seems to become so hot that it turns slower and finally starts to drop frames. This is 100% reproducible on the card I have. I think I will return it and test another to verify this behaviour. This does not happen with my 64gb cards from KompBay.

This is a known issue. You do not have a bad card.
Only USB 3.0 card readers work.
To avoid corruption the Komputerbay 1050x card will not allow to be read by normal card readers (might be a difference in voltage)
I ordered this one: http://www.amazon.de/Transcend-All--Multi-Kartenleseger%C3%A4t-schwarz/dp/B0056TYRMW/ref=sr_1_1

>Unusable on the DSLRs
That is bad, but could also have to do with your setting.
What you could try is change the Photo size to Medium instead of RAW to avoid.
Also you should be on p24 or p25 (PAL) @ 1920x1080.
This full resolution is it seems not possible with p30.
Format the CF card ExFAT to support large files.
Also the ML files should come from a seperate SD card.
And sorry for the stupid advice but probably you lost patience because of the other problems, when the CF card gets formatted sometimes my camera automatically switches to SD card. Make sure you are on the CF card  ::)

If you placed those 1050 xCF cards on a non comapatible USB 2.0 card reader, youcould have corrupted the cards. Your cards has components that cut off like a fuse so you don't permanently damage it. When this happens only your computer can read it but it can't format it anymore.

If you have a USB 3.0 and the cards you say are unusable on dslrs, what exactly do you mean? that when you insert them the camera would say card not formated? or are you saying you can't install magic lantern?

we tested 1000x and 1050x 128 and they work on the mkII but only for canon firmware shooting h264 and stills. No ML and it can't be used to update canon firmware.

on the mkIII it works to record raw video but ML has to be on the SD card not CF, but raw video should be set to record to CF.

please explain by un usable?

Hmm, but it could also be that the CF card has some blocks in the middle are not as good as in the beginning and end.
Because heat is normally a good thing.
What happens if you just format the card immediately after you have this dropouts from the 'heat' and start over.
If it then goes again for 20GB fine then you can rule out the heat.

Hi,

unusable = the DSLRs displaying "Card1 cannot be accessed - reinsert\change card"

and when i tried to format the card from camera i got the same message. the DSLR see a card is inserted but can't read or even format it.
the card was formatted in the PC to exfat, i even tried fat32 i tried every params to no avail before returning it.

on the desktop using a lexar usb3.0 the card was fine. (lexar dual slot USB3.0) 90MB/s WRITE and 120MB/s READ
i was able to format it on the PC via the reader multiple time with various block size but it remains inaccessible to the DSLR
while a lexar 64GB 800x card was perfectly visible and usable for all DSLR operations.

So i'm not even speaking of magic lantern as i'm running it from an eye-fi SD card on the mark III and it is running just fine.
it is just  about the usability of the card as a storage device on the DSLR let alone using it as a ML main storage device..

I returned the card today anyway.. i certainly got a bad controller or something but i can't afford the hassle of testing / returning card while Komputerbay can certainly hire an intern for that and label some card for Magic Lantern users .. like VPG-20 but ML-90 ;-)

They mentioned to use one that contained chips that are compatible with these new fast cards, he also mentioned to AVOID LEXAR CF READERS, as they are not compitible with theirs.

USB 2.0 readers also that contain this chipset (ALCOR AU64771GL-1) are also known to cause corruption.

If komputerbay cards costs so much less than real branded ones like Lexar, there is a reason. They are Lexar defective ones. The defect consist of not reaching the minimal guaranteed read and or write speed. But this is intended not necessarily throughout all the card memory space, but even on only small areas here and there. So this explains the above user results where, at a certain point, the write speed drops abruptly. These komputerbay cards are a real lottery: you can be lucky enough to receive a card whose min write speed is enough for your raw video at your resolution, but also not. Perhaps the low speed area of your komputerbay card will be so at the end of the total memory that you will never use it and so you will be never affected by a problem. And the vendor may also will not refund you for speeds reasons. Someone even talked with a komputerbay representative, and you can find a full report here: http://www.eoshd.com/content/10433/which-compact-flash-cards-for-5d-mark-iii-raw-video.
So, long made short: it is quite pointless to discuss on komputerbay cards, measure them, show personal results or compare their performances. It is a total waste of time, obviously on my humble and personal opinion. I'm only tring to be of help to others to save their time on tests, and others (who still don't have one yet) to save money.

Well, I don't think that you found the ultimate reason for the lower price.
Where is a Lexar 1050x card anyway? Should exist if it get's recycled.
In the discount supermarket you also get the same goods under white labels.

I had numerous, endless returns with OCZ SSD products. 8 returns in 1 month with different products of them. All total failure.
Now that is a brand. And it costs very similar to all the other brands.
You cannot draw conclusions from the price. Democratization of goods is happening.

Regarding the CF card readers, make sure to get a one that was reported to work well and where you do not loose time in the workflow.
It is the lowest cost part of the puzzle anyways.

The Kingston FCR-HS3 is recommended for the best speed results  (source Komputerbay).  ~18 Euro
Transcend RDF8 USB 3.0 Memory Card Reader is ok (source Komputerbay). ~13 Euro
Lexar card readers should be avoided (source forum).

There is no democratization on quality. This is a well established market rule, and forever will be.
The price difference is so huge you cannot talk about democratization ! What democratization ? Chinese one ? Obtained by breaking human rights ?

1050x Lexar are prototyping, and all tests cards failing (even for a small speed amount) are leaked out and marketed by KomputerBay.
This is a normal behaviour.

However, if you still believe in Santa Claus, you are free to believe, but not try to pass for wrong who don't.

I base my conclusions on facts and bibliography (see my link and other posts on the forum).

easy to do 1+1=2, so: Lexar card = good --> Lexar card + Lexar reader = Perfect.    Many thanks !  ;)
Should be avoided with the Komputerbay 128GB 1050x. It is really only about this card.
Sure with Lexar it is fine. No worries.

There is no democratization on quality. This is a well established market rule, and forever will be.
Look at the car industry. Safety of a 13000 car is going towards the same as a 40000 car. At least with European crash tests.
Look at mobile phones. It gets cheaper and cheaper and the quality is really all there. I have a 150 Euro Android. But I had also a Iphone 4s and a Windows 8 one in use. It is at the same stage at the most important parameters.

You may be right that this card is not good. I have not tested it.
But the price of these cards is NOT because it is so expensive to make them. It is only a blown up price.
Manufacturing one of this cards cost 20 USD in China by both Lexar and Komputerbay.

Hi I've just purchased 4 of these from 1050x 128gb cards from Komputerbay, but I'm trying to find a reliable way to test them and to find out if theyre a god send or duds.  Some are benchmarking them at 24p others 25p, some with live view and global draw on, some with both off.  Could someone give me a few ideas as to the settings I should be selecting when benchmarking these cards and ill post up the results I'm getting. 

I know the easy answer is just shoot until it fills the card and if it does without dropped frames its a winner, but there's so many options it'd be good to know what to benchmark it against (eg. Some people are shooting at 1920x1080, others more cropped, some 25p, others 24 etc etc).  If I knew a single set of standards to select it'd make comparing the cards much easier :) thanks in advance for your help! :)

Make sure to test over the whole 128GB as behaviour may change.
Let it run 25p all through when that works 3 times I think you should be fine. Global draw can be helpful when you have a card that allows using it .. makes you loose a few frames normally.

Okay cool, so if I test each card by recording 25p, 1920x1080 with global draw off and it manages it three times that's a good benchmark to the 1050x cards doing what they're supposed to do?

Well bad news.  None of the four Komputerbay 1050x 128gb cards I bought are able to record at 1920x1080 25p without dropping hundreds of frames :-( Looks like these are going to have to go back, unless anyone has any suggestions?

Post by: crazyrunner33 on August 02, 2013, 11:36:26 PM
I would send them back and get a few of the 64 gb cards that have the SM2236AC chipset.  You'll find out if it has this chipset or not when running a benchmark, the chipset is displayed.  I can run around 30 seconds before dropping frames with 1080p @ 29.97fps with global draw on and continuous with the hacked preview when using these cards.  1080p @ 23.976 is continuous along with 2K video at the same framerate.

I plan on sticking with these cards until someone releases a 128 gb that is reliable for 1080p @ 29.97 fps.

Did you try to optimize the alignment. I used the "Paragon Alignment Tool" and it gave me nice speed boost ;)
Sadly ML doesn't run from the 1050x on my 50D :(

Post by: BigChip on August 04, 2013, 03:04:06 PM
Hi guys, just wanted to drop a warning to ML 5D Mk II users. ***Beware of Komputerbay Cards***. I recently purchased the KOMPUTERBAY 64GB Professional COMPACT FLASH CARD CF 1000X 150MB/s Extreme Speed from an Ebay retailer with an excellent rating. I used this card 4-5 times in all manner of modes (using the RAW hack, with ML's intervalometer for RAW timelapse capture and standard 1080 video mode with ML wiped from the card).

I inserted the card into the camera a few weeks ago and got a 'format card' error. The camera could not format the card. Popped the card into an external CF reader and the card could not be read. Tried a different card (Lexar 1000x UDMA 7) in the cam and got the same error.

Sent it into camera shop for repair after trying and failing to problem solve the issue (no bent pins etc). Tech in store conducted a quick test and reported the internal card reader of 5D mk II was fried. Went to Canon UK for repair and this POS card has now cost me €450 in repairs ($600). Turns out the card also blew my card reader so round that off to a cool $650.

From extensive reading it seems Lexar UDMA 7 cards are getting less failures than Sandisk Extreme Pro once firmware is updated to most current version. This issue also very nearly destroyed data shot in a one-off way for a client, took my camera out of action for 6 weeks causing me to use my lower spec b-cam for two other jobs and has been a very stressful road. I'm willing to take a risk using ML on paid gigs for the control it gives me but I won't be so stupid to use knock-off cards in the future, cheaper to cough up and buy Canon-approved cards from a respected seller IMHO. Just wanted to share with you guys so no-one else has to go through this.

My Komputerbay 64GB 1000x card is a little taller than my other CF cards.
It is harder to put it trough my MKIII and CF Reader and I can bet that a wrong insert is the possible cause of the frying the camera.
Not that this is your fault. I'm extra careful with mine here because of this.

Post by: tronics on August 05, 2013, 09:18:49 PM
Ok, I received my KomputerBay 128 GB 1050x card.
I did not do benchmark only regular recording. And I used the Transcend USB3.0 card reader.

I can record with Global Draw On, focus assist, all hacks on, 1920x1080p25 continuous and also 1920x1152p25 continuous.

I'm from europe so 25p is really good to have and our standard to work with.
I was hoping to get 30p for slowmo recordings of nature settings (where there is no electrical light) but this is not really possible - 20-30 seconds only.. for me this is not really useful but to some it might be.

The size of the card is amazing.. a lot of footage fits on there. Offloading is also fast.
For now it seems actually very good.
I need to try more before I can definitly say if the card is really as reliable as it seems.

When I record 13000 frames however after spawning over several 4 GB files the file the recording suddenly stops and cannot be used at all at the raw2cdng.1.2.1
I think that could also be ML. Hmm normally I would never record this long though.

--

I had problems in the beginning. Suddenly dropped frames although buffer was showing continuous ok.
So I felt I cannot trust the card and was a bit sad.

But what helped was that I set the image size in Photomode FROM Large RAW + Large jpg fine TO Small jpg compressed!! From then on I never had a dropped frame.
Then I updated to ML version 2.August, that might have helped as well but I think it was the former.

Best Regards

Sorry for delay. I have contacted the e-bay retailer to confirm that he is a licensed re-seller of Komputerbay cards and that the 'lifetime guarantee' advertised on his site is with Komputerbay rather than him. I am now waiting for the camera shop to forward me on all communications they have had with Canon UK as well as their repair report. When I have all this documentation I will contact Komputerbay so that I will be able to make as strong a case as possible. There is no hard case and they could simply tell me to take a walk (which is what I'm expecting). All I can say is that the camera was working. I inserted the Komputerbay card into the camera, and without even recording any data to the card (just powered up the camera) camera is not working.

I know they're a good deal but it's just not worth the risk to me so I have since shelled out $400+ for two Lexar 1000x 32gig cards for piece of mind alone.

Post by: BigChip on August 14, 2013, 06:00:12 PM
How do you know that it was the card that did this?

Fair question and one that has been troubling me. All I can go on is my personal experience with other cards and the camera. I have shot quite a lot of footage and timelapse material with the camera considering it was only purchased 3-4 months ago (one of the last from B & H). I have used ML more often than not with no major issues. I have had no issues with other cards. The fact that the camera was working with a Lexar card just hours before, and when i booted it up with the formatted Komputerbay card the card reader fault occurred is the most direct reason the card is suspect. The fact that it also took my external card reader out when I tried to format the Komputerbay card and took a very long time to boot up on yet another internal card reader (on a Windows work station) all point to card fault in my mind.

That said here are nagging questions- is this card too fast/ large for a 5D MK II? Could the camera already have had a fault in it's card reader? Maybe this is a knock-off card in some way as I did not purchase it directly from Komputerbay?

Notes that counter these questions- Card appears to have also caused a short in external card reader. Camera was in working order even with a heavy transfer load (ML RAW hack, RAW timelapse capture) with Lexar cards and had been in heavy use with no issues prior to this.

Of course without any electronics training the only way I can test it is to put it back in the camera and let it break it again to confirm that the Komputerbay card is to blame. Obviously I am not going to do it so my best hope is to send it to Komputerbay for testing along with supporting documentation and hope they find something out of the ordinary and pay for the damages.

'And maybe after I've pulled off that miracle, I'll go and punch out God'.

Hello all, seems like these new KomputerBay are worst than the older ones  in term of reliability..

I'm about to buy all equipment for Raw on my 5d3, what do you guys recommend me (i never installed Ml on my 5d3, so don't know yet how it works)..

-1 sd card (to put the ML file in) which one?

- 1000x Cf cards (i think i will go for 2 Lexar 1000x 64gb, the most reliables am i wrong?)

- card reader (wchich one? I heard a lot about the importance of a good one)

-monitor (what do you think about the smallhd ac7? Does it work well with the Ml Raw, and is it 1080p)?

Thanks for all your replies and have a great day!

According to tech support from computer bay; DO NOT use lexar card readers as it has compatibility issues with their cf cards. I used a cheaper SIIG brand usb 3.0 reader and it works fine.

They recommended the Kingston FCR-HS3 reader. My cheap SIIG is ok for me.

I recommend the 64 or 32 gig 1000X komputerbay. Tested them and they are at par with the lexar, which i also have, in speed. The 128gig 1000X also works with raw video though it is slightly slower. The 1050x works also with 5d3 that we tested.

For CF reader, use USB 3.0 and support for udma7. They recommend the kingston fcr-hs3, I got a cheaper SIIG brand usb3.0 reader and it works fine. According to KB tech support, do not use the reader from lexar as it is not compatible with their cf cards.

The thing is, Lexar 1000x cards are not 100% safe deal either.

I owned a Lexar 64gb 1000x and it did ~60mb/s. I couldn't get 1080p24 continuously, even at 2.35 ratio it started to drop frames after ~600.

I sold it and now am waiting for KB 1050x. Hopefully it will do better.

what camera are you going to use the 1050x on? Based on tests I did with it, magic lantern or canon firmware will not work on this card with the 5D mkII and 7D.
It can be used with the mkIII. In out test ML was installed on the SD card not the CF.

If you already bootflaged the camera... any card made bootable should load bins. If you bought 1050x and a new camera then yea, I can see it not working.  If you used the 5DIII alpha which comes as a fir then it would also not work. But otherwise if it reads/writes and you can set the boot sector of the card I can't see any reason why the card won't work.

Post by: ted ramasola on August 31, 2013, 06:06:55 AM
Yup. That 128 1050x really got me stumped.
The cameras were already running magic lantern. When the bootable 1050 was inserted. NO ML, you can snap photos and take h264 vid. The files are fine when accessed.

Tried changing partition, lowered the capacity to different sizes, 64gig, 32 gig, same thing. No mL or canon fir detected.

When you do in camera format the camera disregards your custom partition size and re-partitions/format it back to default of 128 gig.

Post by: ted ramasola on August 31, 2013, 06:39:18 AM
No, it doesnt boot to a black screen. the camera would still boot up but like there is no bootflag or fir. It boots up to default canon firmware.
You check in firmware update menu, its the canon firmware not ML.
 You press update and it says card does not have firmware and tells you take out card and battery. -this is even when .fir is actually in the card.

Got 110mb/sek write on my new 128Gb 1050x KB -card (Crystal Mark). Was able to to fill up the hole card att full HD 25fps with global draw and zacuto EVF. Tested it a couple of times with different settings and had some stops at the half way full mark. I guess there is a slower area somewhere there in the middle. Haven't tested it without EVF and Global draw yet.

The camera got pretty hot when I filled up the whole card. It reached 73C. Not sure if that kind of temperature are potentially harmful or not. Anyone who knows what kind of temperatures the hardware ar designed to handle?

I asked about that a few times and the responses I got was the temp averages at about 70ºC on general run n gun shooting on a 5D MK 3 although I'm not sure how reliable the gauge is (can a dev confirm) or what the average temp should be.

My camera always runs warm running the ML Alpha but before any actually harm comes to you're camera it will automaticity shut off like always (I haven't used ML that much yet on my 5D but I'v never had it overheat and shut off).

I've had a conversation with the tech support at KomputerBay via email to try and clarify a few points that weren't clear to me in this thread. Their customer service is great BTW, they were very fast and helpful when replying to my emails.

In the hopes it can help some others, here is a summary of what I learned:


I hope this helps clear up some of the confusion regarding these cards.

Based on the above I now feel comfortable ordering a 128GB 1050x card from their website for my 5Dmk3. I'll also be getting a USB 3.0 PCIe hub for my PC (it currently only has USB 2.0) and the Kingston Card Reader to go with it.

When the cards are formatted in camera in FAT, I am only able to record to about 8:30 minutes. The files would not span past 10 pieces. (The last one ends with 09) This is very consistent.

If I format the card as exFAT, then I am able to record one ~128GB file to the card, non-stop.

This basically means I have to remove the card and delete the files on the computer every time I want to empty the cards. If you're using a mac, remember to empty the Trash Can after deleting the files, otherwise the camera will still think it's full.

Hi,

I have Komputerbay 1000x 128GB card and 5DmkIII is capable to continuously record raw video only ~8 minutes, right after that recording speed drops from ~90MB/s to 1-2MB/s and then the it starts to slowly recover (up to ~45MB/s) before another ~8 minutes arrives and then the speed drops again to ~1-2MB/s. Any ideas why it behaves like that? Card is formatted in exFat filesystem.
Also, it is weird that although frame dropping is not allowed in the ML menu, the video recording goes on even with ~1-2MB/sec. And not just for some seconds but until the card fills up. Is it because of buffer size and capability to keep the recording alive? Doesn't seem very logical. I haven't checked this specific video data in my iMac yet, but Im pretty sure that the part that comes after 8minutes is not 24fps but probably a lot less. 

By the way, this is the 9th 128GB 1000x Komputerbay card that I have got from them. I purchased 3 cards at the end of summer and so far I have sent them back them three times (last time only sent back 2 cards out of 3 as this one seems to be almost operational. If not count the ~8minutes recording time issue). Main problems were with low recording speed (~60MB/s), strange artefacts on the frames and also becoming non recordable after connecting to iMac via UDMA7 CF card reader and copying the data or experiencing power loss during recording in 5DmkIII (battery run out). Komputerbay denied to refund my money but just keeps sending replacement cards but so far almost all of them have been defected. As I'm from Estonia, sending cards back to them and waiting for new ones takes usually at least a month, so you may imagine my disappointment.

Try first with global draw on but disable all features, if that works enable the ones you wanna use one by one to see if any of them make the continuous recording unstable. Also benchmark your card using Cristal Mark or a similar program on your pc to get an idea of the speed of your card. My card that works does 110mb seq write on my usb 3 kingston reader.

Hi. Just tried again. 5DmkIII, 1080p, 25fps. Constant writing speed ~92MB/sec until exactly 8 minutes and 5 seconds just like the last time. In case of 24fps it`s always 8:25.  Then it drops to 0 and starts to very slowly recover. But recording doesn´t end and frames are not being dropped until the card is full. Interesting and weird. Seems like ML bug or Komputerbay 128GB 1000X defect. Global draw was ON this time, but all the features within it were turned OFF.

About the card itself - ML write speed test shows that the card is able to record around ~75MB/sec but in reality I´m gettin much better results.  I was able to record 2048 x 1152 24fps in crop mode (Globaldraw OFF, frames forced to 24fps in ML) exactly 7 minutes and 24 seconds and then the speed dropped to 0, just like with 1080p. Constant write speed until then was 94,2 - 96,3MB. This happened twice in a row. So, we may assume that the these record durations are somehow related to the recording format/setup.

I´ll try the Crystalmark a bit later today and let you know.

Im experiencing the exact same thing. If someone have a 128gb card of another brand and could test this we could see if it has to do with ml or komputerbay. My guess though is that it is a Ml-bug. Since the card continues recording it clearly writes fast enough. Maybe i should turn on buffer indicators and see how they behave at the 8min mark.

I think bench-marking the card outside the camera is more helpful, in camera is always slower though to cpu bottleneck. My 64gb 1000x cards gets 114 in sustained write in crystal mark so they are still a bit faster than my 1050x card but not by much. It's unfortunate that komputerbay hasn't released the 1200x version of the 128gb a bit more headroom would be nice.

[disclaimer: the following is just my take on the situation without knowing the code or having done much raw recording myself]

The recording not stopping even though frames are clearly being dropped sounds like a bug. It sounds like the stall happens after the same amount of data is written each time:

1080p @ 24fps, 8:25:   ((8 + 25/60) * 60 * 24) * 1920 * 1080 / (1024^3) = 23.4 gigapixels
1080p @ 25fps, 8:05:   ((8 + 5/60) * 60 * 25) * 1920 * 1080 / (1024^3) = 23.4 gigapixels
1152p @ 24fps, 7:24:   ((7 + 24/60) * 60 * 24) * 2048 * 1152 / (1024^3) = 23.4 gigapixels

Do you always start with a freshly cleaned/formatted card before testing this? If so, try leaving a previously stalled recording on the card then try recording again. If there is a bad region on the CF card then you shouldn't see the problem with the second recording. If you see it after the same duration then it seems it must be a software issue. Internal buffers might be slowly filling up, there might be a memory leak of some sort, or a data structure might end up performing badly (eg Hash map with poor hashing algo). Any of those could conceivably mean the loss of frames doesn't get detected as a result of some lag.

Does the recording duration change if you change the amount of memory available (eg by enabling/disabling additional modules)?

Another problem could be the camera heating up however given the consistency of the above numbers that seems a little unlikely. It should also be pretty easy to test for.


Edit: I see Markus has the same problem which makes it much more likely this is a bug in ML. I recently ordered a 128GB 1080x KomputerBay card that should hopefully be arriving in the next day or two - I'll test it and see if I get the same issue.

Post by: Markus on November 18, 2013, 08:09:59 PM
It doesn't drop frames after 8mins Its just the indicator that's acting strange after that mark. It has stopped recording at that point when i had peaking on though...

I've been testing one of these 1050x 128GB cards repeatedly for the last several hours.  It always stops at 8:37.  What's causing that? I have no idea. But I'm happy as long as I'm getting predictable performance.  The card is fast enough; I just can't record takes longer than 8:37, which is plenty for me.

Hi,

First of all – I´m really grateful that you guys are interested in this issue and investing some time for troubleshooting. Thank you very much! I wonder if ML developers (A1ex or anybody else) are aware of this problem? Anybody cares to escalate?

To chris_overseas:

Do you always start with a freshly cleaned/formatted card before testing this? – I tested many scenarios like 1) recorded 3 times on a row to the 128GB card (3 x ~ 8 minutes) while stopped each time right after write speed went down and started again in a few seconds or minutes, 2) manually deleted recorded data via 5DmkIII or PC/Mac and recorded again 3) formatted card in exFAT system and recorded again. Seems like this doesn´t play any role in here.
For me it also doesn´t seem like the actual frame drop although the recording speed is really low (~0,2MB/sec that slowly grows up to 45MB/sec). Although I haven´t actually analyzed recorded data in computer to be 100% sure. During testing I usually record so that camera is basically on the table or on tripod and films some static scene (wall, kitchen, out from the window etc.). So I´m not completely sure. Markus, have you confirmed that frames actually are not dropping or any artifacts doesn't appear on frames (that happened with my last Komputerbay 128GB 1000x cards – ugly horizontal violet/white stripes on some random frames).

Does the recording duration change if you change the amount of memory available (eg by enabling/disabling additional modules)? - If you mean features under Globaldraw then- NO. Time doesn´t change if the speed is decent from the very beginning and exceeds the required limit (83MB/sec, 92,5MB/sec and etc.)

Another problem could be the camera heating up however given the consistency of the above numbers that seems a little unlikely. It should also be pretty easy to test for – one of the latest ML firmwares (I use 15th of November 2013 version) has a temperature sensor that shows the temperature all the time. Haven´t seen that never raising over ~75c. So that should´t be an issue.

Just wanted to add that today when I tried to make external speed test with the card by using PC and Mac I managed to corrupt this last card also. First I tried a PC (notebook) but it only has USB 2.0 so this isn´t capable to show over 30MB/sec. I used CrystalDiskMark. Then I plugged the Transcend RDF8 UDMA7 CF card reader to iMac USB 3.0 and ran the Blackmagic disk speed test that showed nice numbers (up to 104MB/sec) but hanged at some point of time after running around 5 minutes or so and also corrupted the card. Same thing happened also with one of my last 128GB 1000x Komputerbay cards (that is now sent back to KB and once again I´m waiting for up to 4 weeks for replacement to arrive from US to Estonia) and I decided not to try the same combo again – Transcend RDF8 + KB 128GB 1000x CF + Blackmagic disk speed test. :)

So, right now I´m not able to test anything until replacements arrive again. Like I said KB refuses to refund the money saying that 28 days have passed and that was the time for monetary refund. Which is ridiculous cause most of the time the cards are being shipped and not used/tested. Due to that I´m unfortunately unable to recommend to anybody making business with KB company.

BTW - anybody knows how to fix corrupted CF cards? I´m not able to format it nor write anything onto it. The file folders are still present on the card, fortunately empty cause I managed to save the data before the corruption happened. Same thing in 5DmkIII, PC and Mac. Exactly the same type of corruption that happened with couple of previous KB 128GB 1000x cards I had. Didn´t find any helpful information in the internet cause most of the softwares are made to save the corrupted data but not the card itself. Any help would be much appreciated.

You have to be careful what card readers you use, older readers can corrupt the cards! I have read it sets them in write protection mode. Only use udma7 compatible readers! And I'm not sure all Udma 7 readers are compatible... Havent had any problem with my kingston udma7 usb 3 reader though.

I jumped around in my 128gb raw file in mlv viewer. Everything seemed to work fine.
You are testing 1000x or 1050x cards? If you want continuous rec you should buy 1050x.
were are you buying from? I live in Sweden and I can recommend buying from amazon.co.uk if your not already doing that. Closer, faster shipping and no extra taxes if live in an EU-country.

Post by: chris_overseas on November 19, 2013, 12:52:44 AM
OK it sounds like you're both saying that it might just be what is being displayed that's a problem, rather than what is being written to disk. Markus, are you able to confirm whether or not the video is still written out correctly even though the display implied otherwise?

If that is indeed the case then my guess would be that there is some internal math that is overflowing hence screwing up the calculation and display of the FPS or MB/s. I've had a quick look at the code but it's not obvious to me where the problem might lie - partly because I'm not familiar with the code but also because I'm not clear exactly what you're experiencing at the 8+ minute mark. Once I get my 128GB card I'll be able to see for myself which should make it easier to diagnose.

Just wanted to add that today when I tried to make external speed test with the card by using PC and Mac I managed to corrupt this last card also. First I tried a PC (notebook) but it only has USB 2.0 so this isn´t capable to show over 30MB/sec. I used CrystalDiskMark.

It may have been the USB 2.0 reader that triggered the problem (even if you didn't notice the symptoms until later). Have a read of my earlier post:

http://www.magiclantern.fm/forum/index.php?topic=6884.msg88538#msg88538

I'm still quite worried about card corruption on the KomputerBay card I'm about to receive. One thing for sure, I'm only ever going to put it into a USB 3.0 reader.

Hi,

Thanks guys but:

1) Transcend RDF8 is USB 3.0 UDMA7 supported card reader. Link: http://www.transcend-info.com/products/Catlist.asp?modno=331
2) I have also tried with other popular card reader and experienced same issues. Kingston fcr-hs3. Link: http://www.kingston.com/us/flash/readers#fcr-hs3
3) All my cards have been Komputerbay 128GB 1000x UDMA7 models. I belive 9 cards so far (3 shipments, each time 3 cards). I'm not even complaining about the speed this time because I was able to record 1080p 24fps, 25fps and even crop mode 1152p 24fps just great. Just two things that worries me: a) the write speed that suddenly drops  after ~8 minutes, is this just a visual glitch or it also affects the frame count or their quality (still hoping to get answer about this from Markus) 2) why these cards break down with Blackmagic speed test and sometimes even when abnormal power disconnection happens (camera battery runs out in the middle of shooting or you disconnect your cardreader from computer without safely removing hardware.
4) I ordered my first batch (3 x KB 128GB 1000x cards) from Amazon.co.uk in summer but shortly after that appeared that the cards actually came from US and the shipping time was therefore longer. That also reflected in price, because they didn't make the VAT discount like all companies in UK must do. So, although I can see currently that they have changed some shipment politics, my replacement cards are still coming from US, I'm pretty sure. Because of the long time it takes them to arrive each time. For me personally it is out of the consideration to buy another card from them (I don t trust this brand anymore) and my biggest pleasure would be monetary refund. But as I said, they denied, so I have no other option to accept replacement cards again and again. Hopefully not till the end of their existence. BTW, I just checked, KB doesn't ship to Estonia from Amazon.Co.Uk so that's why they send me from US: http://www.amazon.co.uk/gp/help/customer/display.html/ref=mk_sss_dp_1?ie=UTF8&nodeId=200039400&pop-up=1

Eligible European Destinations:
(Belgium, Denmark, Luxembourg, Netherlands, Finland, Gibraltar, Iceland, Ireland, Portugal, Sweden and Poland)

And two more things:

1) Please ignore my request for help withCF card restore, this is pretty obviously impossible in home conditions and that's why companies like this exist (see also the video): http://card-recovery.biz/us/service.php
Most probably this is hardware issue and I can't do anything about this myself. Tried already several softs and PC/Mac features.
2) I must figure out how to maintain these cards safely in the future. What can and what cannot be done. Like this Mac + Transcend reader + Blackmagic soft example. Most probably I replace my CF card reader (cheapest expense), dont't ever use Blackmagic speed test again and also don't ever format my KB cards in Mac. After coping the data to local disk I plan to clear the CF card with deleting RAW files via ML File Manager in 5DmkIII.

I received my 128gb 1050x card in the mail today. Installed ML. and ran Benchmarks on my 5D Mark II.  after 5 tests in a row i have concluded. A - I'm a idiot or B - this card SUCKS! My 16gb Sandisk Extreme 60MB/s memory card clocked in better benchmarks!  I will be contacting customer support but would like your guys opinion. I've attached 2 of the best tests of the 1050x card. As far as testing Raw recording at 1880x800 the most frames i could record was 253 frames before it drops. This was my first high speed memory card purchase so I'm kinda bummed.

dannyhu: I'm not sure what speed a 5D2 is supposed to be able to write at. I know the following spreadsheet says 75MB/s: https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5 but is that what other people are hitting in practice?

I notice you're running a pretty old build of ML. Have you tried with the latest nightly? Also, did you try running the card warm-up before the benchmark?

If that doesn't help then do you have a good (UDMA7 USB 3.0) card reader? If so, try benchmarking the card with h2testw.exe (www.heise.de/ct/Redaktion/bo/downloads/h2testw_1.4.zip) to see how the card performs without the camera being a factor.

I had a 128GB 1050x KomputerBay card delivered yesterday and I'm seeing 90-100MB/s write speeds with it when benchmarking on my 5D3.


For anyone who is looking for a good card reader for their desktop PC: I just installed the Akasa AK-ICR-14 internal (3.5" drive bay) USB 3.0 card reader. Before buying it I confirmed with Akasa support that it can handle UDMA7 transfers. With my 128GB 1050x card I'm getting ~90MB/s write and ~110MB/s read speeds so I'm pretty happy with the Akasa so far. If you decide to buy it though be careful - they also have other models that look very similar but the card reader portion of those devices is only USB 2.0. Here's a link to the product on their website, but to buy it you'll need to go via an online retailer rather than through them directly: http://www.akasa.co.uk/update.php?tpl=product/product.detail.tpl&no=181&type=Card%20Reader/Hub&type_sub=Card%20Reader&model=AK-ICR-14

Chris_ I installed the newest nightly build for my 5d mark ii and retested my benchmarks. Customer support emailed me back last night at 2am!!!! asked me to go to Overlay Tab and only have global draw in LiveView. everything else turned off. Movie tab - bitrate set at default, and fps override at 23,976. Movie mode at 1920x1080 24p with global draw off average Benchmark is 38.65MB/s Write and 43.25MB/s Read. In playback mode with global draw on. average Benchmarks are  70.98MB/s Write and 97MB/s Read.

The only resolution i can record at without any dropped frames is 1280x720 at 23.976. My bench mark for movie mode are not even close to letting me record at the maximum resolution of the write speed. I feel like im going to have to cut my losses and send it back. do you guys have any suggestions. should i try something else.

Markus, in a meantime I had a chance to test the "writing speed bug" with 64GB Sandisk UDMA7 90MB/s CF card and same issue happens with this card. Exactly 9minutes and 25seconds writing speed drops to ~0.00MB/s and slowly starts to recover but with this card recording stopps at some point of time before card fills up. I tested this twice. So this speed drop still affects recording but I still don't know if frames that are recorded after that 9:25 are somehow defected or not. Or if any of those frames are skipped or not. Would you please be so kind and test it? I'd do it myself but I had to give back the Sandisk card and my replacement Komputerbay 1000x 128GB cards are still yet not shipped.
Thanks! 

I think now it should be proper time to escalate this bug to ML development guys, because this is now clearly ML defect and not just Komputerbay cards specific bug. Who should I contact? A1ex?

1) Is continues 25p 1080p raw recording easily possible? With Globaldraw ON?
2) Will 5dmkIII recognise the card as exfat 256gb and uses all the space?
3) whats the highest resolution/framerate this card can handle with ML continues Raw?

That card can handle full HD cont. without any problems. As my cards now that benchmark around 105-110mb sek can film full HD cont. with global draw on I am sure the 1200x card that does around 140mb/sek will work. However It might not work with all global draw features enabled. The camera-cpu and udma interface are the limeting factors here.
The sad thing about the 256Gb card is that It's not compatible with the mk III. As I understand it the camera is able to se the full size of the card if formatted in exfat but the camera stops recognizing the card when you have recorded 128Gb of data.
Im not sure if it works with newer canon firmware or if canon plans to adress this...

Truly sad though, 47 min full hd 25fps raw on one card would be killer =)

Hi!

Markus, if your opinion is based on Ted Ramasola case, then for me it looks like he experienced this capacity issue only with 5DmkII. I can't find any proofs that this is also present with other 256GB CF cards beside Komputerbay and any other cameras beside 5DmkII. And only one case - Ted Ramasola. AFAIK Canon claims that 5DmkIII camera is perfectly capable to use the whole 256GB CF card. If you have any other details, please let me know. Because my purchase is on hold due to this capacity issue suspicion.

I asked for more details there: http://www.magiclantern.fm/forum/index.php?topic=7801.msg90381#msg90381

Thank you!

Yes it's based on his account. If you try this be sure too update your findings! Hope he's wrong. I was about to buy one from komputerbay myself but in contact with them they said it was only supported by the 1dc so at that point I changed my mind an bought two 128GB card instead.
But I don't know anyone except Ted that has tested this...

Chris_ I installed the newest nightly build for my 5d mark ii and retested my benchmarks. Customer support emailed me back last night at 2am!!!! asked me to go to Overlay Tab and only have global draw in LiveView. everything else turned off. Movie tab - bitrate set at default, and fps override at 23,976. Movie mode at 1920x1080 24p with global draw off average Benchmark is 38.65MB/s Write and 43.25MB/s Read. In playback mode with global draw on. average Benchmarks are  70.98MB/s Write and 97MB/s Read.

How can I install ML on a 1050x 128gb brand new Komputerbay on my 5D mark II ?
I tried to copy the ML files from a previous  CF running ML and booting the KB card with macboot but ML doesn't boot :(

Thanks

I'm not sure so I'll ask. Is this card fully compatible with raw in the 5D Mark II or there's still structural problems and I have to take another 64GB card?

I recently purchased this last week and so far it is working flawlessly. My question is with the card reader for this card. Will using a USB 2.0 reader on a 3.0 USB port be a problem? This is just temporary until I purchase a 3.0 reader.

If its USB 2 there is a big chance of it not being compatible with udma7 cards. You will risk corrupting the card. Only use supported readers!

Anyone tried the 64gb 1050x CF card?
it's the same price as the 128gb 1050x CF, so that's a bit confusing but perhaps the speed drastically improves?

Benchmark was developed to measure maximum speed performance at different cluster size.

I believe during playback-benchmarking there is less use of the CPU so that the highest recording speed can be obtained and compared to what the manufacturer claims.  If you benchmark in movie mode then there are a lot of settings that can slow down recording so it is not recommended to test in this mode.

To Benchmark you card properly for MAX speed compatible with ML:

1. Go to ML and turn OFF Global Draw
2. Do not test while LV is active, meaning not in video mode or photo with Live View Mode.  This is refereed to testing in Playback mode
3. Make sure your Camera Auto Power off is disabled in Canon menu.
4. Go to the ML menu and find the Debug menu and then the Benchmark, and select Card R/W benchmark (5min)

When the benchmark has finished ML will automatically record the bitmap image in your card.


VERY IMPORTANT

Make sure that in Canon Menu:
Image Quality = Raw for (5D3, 650D,  ....) some others may be better in jpg
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO speed NR = OFF
Highlight tone priority = OFF
Multiple Exposure = Disable
HDR Mode = Disable HDR

and.. to get the zoom function to work in LV you need to "Enable" Live View shooting  and also AF mode set to "Live mode", of course this is done in Canon menu.  check your camera specifics to the zoom function working in Live View

In a nutshell, as the thread is 9 pages long, does the 128GB 1050x cards do the following?

1) Consistently surpass 67MB/s write  on your EOS body & card reader transfers?
2) Consistently surpass 105MB/s read on your EOS body & card reader transfers?
3) Have you returned any Komputerbay card?
4) When receiving the returns did they break also?
5) Any chance it can surpass 90MB/s read/writes on your EOS body & card reader transfers? 90MB/s read/writes are what my Photofast 533x Plus cards can do.

I need to ask this as my order will land within the US and will be hand carried to the Philippines by a buddy.

Your feedback is most valuable as I have noticed that ML users have a significantly higher end requirement than I do so if it is up to standards for all ML users then it is more than useful to me. My primary use would be stills at the high-speed continuous drive mode of 6-12fps.

I will be using the card on a stock 7D, 5D2, 5D3, 1D4 and 1DX with a Lexar® Professional USB 3.0 Dual-Slot Reader attached to Macs with 10.9.x and 10.8.x

Alternatively have you guys tried 128GB RiData 1000x CompactFlash cards?

this was just a great post.. after making your setup of my 5D3 i got theese results.. i think i should be quite pleased?

Komputerbay 1000x 128gb card bought a week ago.

How do i force the camera to use the best buffer size? or will it do that auto?

but then my recording looks like this... is the green line the buffer?

I have a upcoming shoot in less than 2Weeks, we want to shoot @ 50fps. So far I am using my KB 64GB 1000x which works fine @50fps upscaling to 1920*818.

I am not sure if I should get the same card again or maybe use the 128GB 1050x? Anyone tried 50fps or compared the 2 cards?

Get more 64gb cards, the 128g 1050 isn't all its cracked up to be. Its slower. And a benchmark in playback is useless. So those numbers of 110-115 will not happen when you are actually recording.  I went from the 128 card to the 64gb and all the performance unreliablilities went away.

When you look at the card tests for different buffers on these tests.

64Gb - Out of the top 8 buffer sizes, 7 could do continuous recording.

128gb - Out of top 8 buffer sizes, 5 will do continuous OK.... probably, 2 of them are on the edge... so probably more like 3 out of 8.

The 64gb card is just way more consistent across the different buffer sizes.  I was convinced to get the 128gb 1050 card.. and i wish i just got the 64gb from the start. Don't get me wrong, the 128gb card is great.. inexpensive.. and fast... but not quite fast enough to be used in RAW with consistent performance.

And remember, if you are recording at High FPS those modes transfer even slower than in 1080p mode(at least i cant find a way for it to do it at the same speed) Regardless of card recording at high FPS seems to stay below 80mb/sec even though in 24p 1080p mode it tapes 110mb/sec on the 64gb card.

Thanks for the fast reply, i guess i will get some more 64s than. I had a similar issue, recording normal 1080p @ 25fps i got a little over 100mb, recording higher fps i only reach around 80mb :(

Thanks anyway, cant wait to shoot and see the results :D

I'm not sure if there are some settings i've messed for the high FPS stuff. But If you could have the data rate stay the same as the 24p 1080 settings then you could probably do 15 second clips at 60p 1080... but since its drops to like 80 thats only your buffer.

I got one of the unbootable KomputerBay 1050x 128GB CF cards, and it seems a very unconsistent performer in RAW recording benchmarks as well.  Even at 24 fps 1080p with no audio and Global Draw off, would I very often receive dropped frames early on.  I am going to send the card back to give another one a second chance.  In e-mail correspondance with KomputerBay, they claim it is impossible to acheive 1080p RAW recording at 30 fps with the 5D Mark III:


Quote
You will not be able to achieve 1920X1080 @ 30fps without spanning. The max you can achieve will be 25fps. 30fps required a little more than 100MB/s (106~108MB/s) and the CF slot on the 5DM3 is limited to 100MB/s. You will get 2-34frames before your camera heats up and shuts down (also not recommended). The problem is not the card - but the camera's bottleneck. The benchmark we sent you is was for the 128Gb card - as you can see it will very well achieve above 110MB/s on the 5DM3 but the camera itself is limited to 100MB/s for continuous raw.


I may have missed this official discovery here on the forums, but I hope that they are incorrect!  UDMA 7 specification allows for 167 MB/s of throughput with CF version 6 specification, as far as I am aware.  It would be disheartening to hear that we could never acheive RAW 1080p/30 recording using the CF bus on the Mk3.

When I receive my replacement card, I will post benchmarks to this thread.  I hope to report good news!

That Is quite an accurate account from komputerbay I'm afraid. Best card for stable results for full hd raw with sound is the 256gb 1200x KB card.

I just bought a 50D and one of these cards. I performed a benchmark and am very happy with the results. I got up to 87.5MB/s write speed on the 50D which supposedly has a max write speed of 70MB/s, I'm guessing this is due to the buffer but it's definitely an impressive card, especially for the price.

Here it is...my first post! Bought the KB 128 1050x and tested it today. Without doing anything or formatting I put it into the 5D3. It made 8 minutes of continuous 1920x1080! But then it dropped frame and said: "failed to open file.card full?" . What does this mean? What do you think would be best to do? How are KB CFs formatted out of the box? I'm a very beginner with ML. Would appreciate some advice/suggestions to get reliable results in the future. Bought New Kingston reader too but the card saw no reader until now. Best Jürgen

For stable continious results buy 64gb or 256gb 1066x  KB cards. The 128gb versions are not as stable for some reason.
Also be sure to enable larger than 4gb files option in mlv raw menu.
