SD Overclocking - DIGIC 5 only
« on: February 12, 2021, 10:32:15 PM »
Experimental SD Overclocking module with selectable presets (160/192/240 MHZ) for DIGIC 5 models only (5D3 1.13 / 5D3.123 / 6D.116 / 70D.112 / 700D.115 / 650D.104 / 100D.101 / EOSM.202).

Download / Source code / Technical discussion



Stock 700D                                                   160MHz                                                        192MHz                                                        240MHz


How to:
-You need a build based on crop_rec_4k branch (Experiments / crop_rec builds)
-Download sd_uhs.mo and put in your SD card in "ML/modules" folder
-After loading the module in camera, select a preset (160/192/240) then restart the camera
-Run "Benchmarks" test from Bench.mo in Photo mode
-Share the result, your card name, selected preset.

Notes:
-Best compatible and recommend card is Sandisk Extreme PRO 170 MB/s (works in all presets flawlessly - tested on 650D/700D).
-Sandisk Extreme PRO 95 MB/s cards are stable when using 192 MHz preset (240 MHz isn't , mostly won't work).
-For some reason not all DIGIC 5 cameras would work with 240 MHz and Sandisk Extreme PRO 170 MB/s card (like EOS M).

-Perform "Low Level Format" in the camera if you had speed drops, test again.

Eosm max out on 192Mhz, 5D3 no more than 160Mhz if I recall correctly.
I also donĀ“t trust the same patch routines here for 5D3. I do other stuff when patching 5D3 so beware.

Confirmed: 70D can do 240MHz as well.



The card was Sandisk Extreme PRO 170MB/s 64GB.
With the older 95MB/s version of the card the 192MHz preset works well (results like on 700D) but the 240MHz falls back to 20MB/s.

Thumbs up Bilal! Great achievement!

Nice results! Thanks for testing!

Could you do one more test (Benchmarks) with Sandisk Extreme PRO 170MB/s @ 240 MHz in Video Mode (1080p24 from Canon menu), in that mode on 700D the max write speed ~68 MB/s .

I'd like to see what 70D would perform, it has DIGIC 5+ (700D has DIGIC 5) and more RAM (maybe also faster RAM than 700D).

Thanks!

Cool results! 70D could handle continuous recording in higher resolutions better than the entry level cameras like 700D and EOS M.
