After enabling the overclocking by adding amdgpu.ppfeaturemask=
=3D0xffffffff
kernel boot parameter I noticed that my GPU works very slow. I noticed by
reading /sys/kernel/debug/dri/1/amdgpu_pm_info that the card fails to go to
higher power states.

Here are the screenshots and the way I found to temporarily fix it. I am us=
ing
Witcher 3 on Steam Proton 3.7.6 as a performance measurement:

1). Initial state. The game is running around 15-20 frames. The
pp_od_clk_voltage table seems correct but the power consumption stays aroun=
d 15
Watts and the clock is stuck at 300 MHz

3). Writing a value in to that is already on the table of pp_od_clk_voltage=
 is
also not helping.

4). Setting a value slightly different than will actually allow the GPU to
change its power state to a higher level. However, it is still not fully
powered as it would be  without overclocking enabled. The frame rate is only
20-30 and the power is around 80 Watts.

 100
frames per second and power consumption to 100 Watts.
