I tried -cclock, but it didnt seem to have any effect on Radeon R9 290X. I also tried to write to /sys/class/drm/card0/device/pp_sclk_od, according to this
https://www.phoronix.com/scan.php?page=article&item=amd-rx480-od&num=1but the value didnt change from zero.
Is there a way to overclock Radeon R9 290X in Claymore? Im using AMDGPU-Pro Driver 17.40
you probably should try 9 something like 9.6 it will not have new amd api and will work with proper drivers... like 16.10.4 or smth
EDIT: ohhh. nix user, still the same issue... maybe
