I suppose also the Windows driver enforces maximum VRAM clock in your case all the time? If that is true, it would definitely be a cool thing if we could get a patch into upstream to cover that as well (Ahzo's patch landed in amd-staging-drm-next branch).
I don't have Windows installed on my machine so I don't know. Anyway the linux driver enforces VRAM clock because of my two monitors are out of sync, and memory reclockimg causes flickering (if I understand correctly what driver's code do). My patch fixes a bug that breaks this behavior when OverDrive mask is enabled, nothing more.
