Hi there. So I've been playing around with my pi3b+ and got some pretty good results with overclocking. But the last thing I'd like to tweak is the SD card speed. I've been reading online about the line added to config.txt to get it working but the bit I'm a little confused about, is to get a full 100mz the core has to be set to specific speed. I tried adding the line to config.txt and querying the speed with the command on the retropie wiki, but I'm only getting about 83mhz. I'm using a Samsung Evo+ card, so I'm confident it will take the tweak. I'm running
Arm at 1450 overvolt 4
Ram 500 overvolt 2.
What would I need to set the core to get 100mhz out of the SD card?
Thanks in a advance.
