(New OP 21/9/2022)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 / EOSM2 1.0.3).

How to:
-You need a build based on crop_rec_4k branch (
Experiments /
crop_rec builds)
-Download
sd_uhs_compiled.zip, then extract it somewhere on PC
-Copy sd_uhs.mo to 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.
SD card recommendations:
-Any SD card with W90 label (capable of 90 MB/s write speed) should work with 240 MHz or lower.
-List of SD cards which were tested and they work fine at 240 MHz (pay
attention to SD card capacity,
lower capacities may
not be capable of 90 MB/s write speed):
- Sandisk Extreme PRO 95 MB/s (64 GB or higher, SDR50, 32 GB isn't stable at 240 MHz)
- Sandisk Extreme PRO 170 MB/s (64 GB or higher, does 32 GB work?)
- Sandisk Extreme PRO 200 MB/s (64 GB or higher, does 32 GB work?)
- Sandisk Extreme R190/W130 (256 GB or higher, do lower capacities work?)
- Sandisk Extreme Plus R170/W90 (256 GB or higher, do lower capacities work?)
- Samsung PRO Plus (128 GB or higher, does 64 GB work?)
- Samsung EVO Plus (256 GB)
- Samsung EVO Select (256 GB)
- Lexar UHS-II V90
- Lexar Professional 256GB 1066x SDXC UHS-I (Silver Series)
- Kingston CANVAS Select Plus UHS-I, U3, V30 (128 GB or higher, does 64 GB work?)
-SD cards which
doesn't work well at 240 MHz:
Notes:
-SDR104 is selected by default which should work on all fast SD cards (UHS-I W90). Only try SDR50 when SDR104 fails. Like with
Sandisk Extreme PRO 95 MB/s case.

-Some models will have "(H)" beside some presets which indicates that
Hybrid clock speed will be used; clock speeds for read operations will be different (slower) from the one for write operations.
This won't affect write speed performance. Read speed benchmark will not represent the actual read speed for an SD card at an selected frequency (only in (H) case).

-Some SD info can be found in "Show CID info" option.

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