In windows I can push my Memory Clock beyond 2300 Mhz. I can push it up until windows crashes and I can see the temperature increase. In Linux the Memory Clock is capped at 1200 Mhz the GPU isn't even hot and the computer is stable.
cat /sys/class/drm/card0/device/pp_dpm_mclk
0: 96Mhz
1: 541Mhz
2: 675Mhz
3: 1200Mhz *
Is this an amdgpu driver limitation? Can this be overcome or do new drivers need to be developed?
