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=20
0: 300Mhz=20
1: 608Mhz=20
2: 910Mhz=20
3: 1077Mhz=20
4: 1145Mhz=20
5: 1191Mhz=20
6: 1236Mhz=20
7: 1306Mhz *

# cat /sys/class/drm/card0/device/pp_dpm_mclk=20
0: 300Mhz *
1: 1750Mhz=20

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!
