My MSI r9 390 forces the memory clock to 150000 if I plug in m=
ore than one
monitor. The card draws 40 watts more power while idle and keeps the fans
running all the time.

This is happening with both amdgpu and radeon and I can fix the problem by
disabling dpm, but this causes some other issues.

I read earlier that this behaviour is intended and is a common problem with
graphics cards but IIRC a recent driver update fixed this on windows so I'd
like to know if there is any chance to also get a fix on linux?
