Thanks for your response. I somehow forgot the missing ">", whoops. I now almost got it working like desired, thanks! However, there is a small problem left: It doesn't switch into pstate 7. I set up: echo "manual" > /sys/class/drm/card0/device/power_dpm_force_performance_level echo "s 0 214 721" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 1 389 721" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 2 844 725" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 3 1009 818" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 4 1079 875" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 5 1134 880" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 6 1179 890" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "s 7 1209 900" > /sys/class/drm/card0/device/pp_od_clk_voltage echo "c" > /sys/class/drm/card0/device/pp_od_clk_voltage But according to /sys/kernel/debug/dri/0/amdgpu_pm_info, pstate 6 (1179 890) is the maximum of chosen clocks. I set up Unigine Valley to run in 720p with 8xMSAA, so there is no high power consumption which could make the GPU throttle down to a lower state, so it definitely should switch to pstate 7. I also tried making s 7 and s 6 the same, but then it's just limited to an even lower pstate. So I fail to get to my desired 1209MHz 900mV. It also seems like setting up power_dpm_force_performance_level to manual isn't actually required, at least it doesn't make any difference here (or I'm missing something). Btw: Since I'm already bugging you with this :) : Is there a way to also increase the maximum allowed power consumption? There are /sys/class/drm/card0/device/hwmon/hwmon0/power1_cap and /sys/class/drm/card0/device/hwmon/hwmon0/power1_cap_max containing the maximum ASIC power (at least it looks to me that way), but I haven't been able to successfully alter those to e.g. raise the limit of my Baffin GPU to 60 Watts.
