Thanks @theBilalFakhouri

I've actually tried two 170MB/s SD cards a 64GB and 128GB both with the same result.

I just tried again:

  • did a low level format
  • installed ArcziPL's latest build April 04
  • Enabled sd_uhs.mo and rebooted
  • selected the 240mhz preset in photo mode
  • Benchmark reported 95MB/s write and 106MB/s read
  • Then switched to mv1080 and ran the same benchmark and got 20MB/s for both
It's a similar story for 192Mhs preset.

Tried the same as above with your module with the same results.

And thanks I'll take a look at that link. :)


edit: i'm actually getting memory allocation errors in mv1080 read benchmarks, so about 20MB/s writes mem alloc error on read

Hi there,
I'm trying to figure out how to get this working on my 70D, for some reason only ArcziPL's mar19 build is working on my model, his newer builds aren't. Interestingly it worked for a week and then randomly stopped.

(Heads up I don't know ASM so I'm so sorry if this is a stupid question but I guess we've all got to start somewhere and I'm really hoping I can contribute to the community)


I'm struggling to figure out a few things:


  • When I search for the register addresses in my rom dump I can't find them, can you please advise? I'm sure I'm doing something wrong
  • what do the overclock values actually refer to?

Also If you have any recommendations on resources that would help me understand the above I'd really appreciate it.

Thanks in advance.

Just an update from my previous post, sd_uhs seems to be working with the march2019 build so will stick with that for the time being while I try to figure out how to play around with the code, the one thing that baffles me is that it was working, very strange!

I managed to get my dev environment set up on a laptop I have running Ubuntu 20.04 already, I think I'll try to document this process as all the how-to's on the forum are a bit out of date. I also managed to get a compiled ML running in Qemu using my ROM dumps :)

Hi All,
I think this is my first time posting here, I've searched high and low but can't seem to find a resolution for my issue so hope someone here can help please?

I had sd_uhs.mo on the latest build working great for about a week on my 70D with a sandisk 170MB's extreme Pro SD card, but now for some reason the sd_uhs module has stopped working in MV1080 mode.

Benchmarks in MV1080 mode are as follows:
160MHz = = W/20.2MB/s R/21.1MB/s
192MHz = W/20.3MB/s R/21.2MB/s
240MHz = W/20.5MB/s R/21.2MB/s

Actual video recording bitrates reflect the above too.

play-mv LCD mode:
160Mhz = W/66.2MB/s R72.0MB/s
192Mhz = W/77.6MB/s R/86.0MB/s
240MHz = W/91.3MB/s R/106.6MB/s

Benchmarks without the module loaded hover around the 40MB/s mark.

There is a red dot next to memory patches in the debug menu, I don't know if this means anything?

I've reloaded ML several times now, formatted the SD card too. I've also tried with a second identical card to no avail...

Am I missing something really obvious here?

Thanks in advance!

P.S ArcziPL, Is your source available please? I would love to have a play and contribute if possible?

Many thanks
