Look if you can find /sys/class/drm/card0/device/power_dpm_force_performance_level

and then you echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level

that should set the coreclock to highest setting.

To further increase coreclock und vram clock you can do that in

/sys/class/drm/card0/device/pp_sclk_od

=> GPU clock seems to be a sort of multiplier CAUTION!!!

/sys/class/drm/card0/device/pp_mclk_od

=> MEM clock seems to be multiplier CAUTION!!!!

hope that helps you
