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.

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 1

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  :o (which ofcourse should be ridiculous  :P )

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  ;D

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.

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 ...

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