Commen= t # 6 on bug 10630= 3 from Julian 
Can confirm. I'm using a Rx 560 on kernel 4.16 and my clock ra=
te is stuck on
1230MHz permanently.

I'm also using a single 2560x1440x144 monitor

This is directly related to DC. If I run with amdgpu.dc=3D0 the issue disap=
pears.
If I run with amdgpu.dc=3D1 it shows up. I can't say if it also happened on=
 4.15
or earlier.

I did notice that dmesg shows about a dozen powerplay errors:

[   94.582083] amdgpu: [powerplay]=20
                failed to send message 146 ret is 255=20
[   94.582091] amdgpu: [powerplay]=20
                failed to send pre message 147 ret is 255=20
[   95.895976] amdgpu: [powerplay]=20
                failed to send message 145 ret is 255
