Hi, After changing the current performance level with: echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level only the shader clock is updated but not the memory clock. # cat /sys/kernel/debug/dri/0/amdgpu_pm_info [ mclk ]: 300 MHz [ sclk ]: 1306 MHz # cat /sys/class/drm/card0/device/pp_dpm_sclk 0: 300Mhz 1: 608Mhz 2: 910Mhz 3: 1077Mhz 4: 1145Mhz 5: 1191Mhz 6: 1236Mhz 7: 1306Mhz * # cat /sys/class/drm/card0/device/pp_dpm_mclk 0: 300Mhz * 1: 1750Mhz Same issue if I choose the manual mode and try to echo 1 in pp_dpm_mclk. Tested on Linux 4.8 with RX480. Thanks!
