I am trying to overclock the memory on my GPU with AMDGPU Pro 18.40 driver.
/sys/class/drm/card0/device/pp_od_clk_voltage is an empty file and I cannot write to it.
When I try
echo "m 2 1600 950" > /sys/class/drm/card0/device/pp_od_clk_voltage
as root it produces the following error:
-bash: echo: write error: Invalid argument
I have also tried running:
echo manual | sudo tee /sys/class/drm/card0/device/power_dpm_force_performance_level
My question is based on the answer to the following question: Can't overclock GPU using amdgpu driver on archlinux The author claims that this method works, however it obviously does not.
