UHS-I / SD cards investigation

[70MM13]

PS: should i have seen the overclock menu item?  i did not.  i guessed it was because you have hardcoded it, but maybe it just failed to load, although there was no error message...

[Levas]

You can check if the patch is done on the Debug tab in ML menu.
The menu item 'memory patches'
should show 3 rom patches.

[70MM13]

0 patches

rebooted several times.  always 0.

edit: should i be running a specific build?

[Levas]

Should work in the crop_rec 4k build from the experimental downloadspage.

But if you haven't got a compatible build, I expect you get an module error message at startup ?

[70MM13]

i'm using danne's very latest, june 27.  no error messages.
i'll try the standard nightly build now...

[Danne]

Don't use the automated sd_uhs.mo for eosm and 6d. That is why I custom build the module for 5d3. I can build a few versions tonight for testing.

[70MM13]

thanks danne,

here's the error i got using the nightly build

Below for 5D3 with my experimental builds. The ongoing patches from bilalFarouk...Obviously you need to erase prefix patch_1_ and prefix patch_2_ before adding it in modules folder.

patch 2 WORKED!!!!!!!!!!!!!

it recorded at 80.x MB/S for 3 recordings in excess of 1 minute each, strictly to the sd card.

the 4th recording didn't work, with the "card full" error (card wasn't full)

i looked at the resulting video files and they were perfect.  no lost frames, no issues of any kind!

this is VERY exciting stuff, wow!

[Levas]

So... ~80Mb/s on the sd card unit only of the 5d3.
How fast was the compactflash drive again ? ~100Mb/s.

Does this mean, that with card spanning, the 5d3 could do ~180Mb/s  (which ofcourse should be ridiculous  )

Unexpected since card slot in 5d3 is a slow story. Did you test card spanning?
@Ilia3101, check this out...

[Levas]

Not sure, but isn't it expected that the 5d3 has the same sd card slot as the 6d (or vice versa) ?
Both were introduced in 2012 and within half a year of each other.
Both cameras are also digic5+

Edit: Patch 2 are the same settings used on the 6d and give ~80Mb/s on the 6d (Climbs up to 88Mb/s)

[Danne]

Maybe so Levas. Didn´t bother too much around sd slot but if that´s true card spanning might get a real push forward here. Around 130-140Mb/s. Too bad I don´t have my 5D3 with me. Only carry my eosm everywhere.

[70MM13]

i just tried dual card mode...

3616*1536*14 bits lossless, continuous!!!

i recorded 5 clips in a row with no errors.

131 MB/S, very evenly divided, both slots in the 60's

damn, this is getting exciting!

[Levas]

Ok, I'll admit, I'm jealous now 

[Danne]

Not bad at all!

[nikfreak]

this will drive some nice traffic to the website once stable.

[Levas]

@Nikfreak, do you still have a 70d ? (as stated at the bottom of your posts)

Because 70d is also digic5+.
So curious if the sd card slot behaves like the ones on a 6d and 5d3. If so, 70d probaly also has 80Mb/s write speed.

650D user here waiting for compatible module.

[Levas]

Here's the sd_uhs module that is automaticcaly activated at startup:
This one is with the settings that work for 700d and EOSM:

If the above doesn't work, you can try the module I posted earlier today, that one uses the settings that work for 6d, but the module should do the patching on 100d, 700d, 650d, 70d, 6d and EOSM.

[Danne]

I already added the latest sd_uhs module to the eosm build. The usual place.

[Walter Schulz]

Your latest module with 650D crop_rec_4k.2018Jul22.650D104
Read runs like a clock and gives around 85 MByte/s.
Write not so much. It begins very fast but hits a break ("break" point varies in different runs) and is seriously slowed down. Accelerating after and result is in the 68 MByte/s range.

[Walter Schulz]

Tested previous version. I have no words ...

[70MM13]

wow, this is turning into a magic lantern history day!

[Danne]

Tested previous version. I have no words ...

Exactly what version ?
