I recently bought a Sapphire R9 390 gpu to replace a HD6970. The problem is I get black screens when I watch video or just idling at desktop. The only "fix" is to underclock the gpu when doing 2d stuff, by using a profile at MSI Afterburner. I have a second profile for gaming with stock settings.
I have tried every Crimson driver there ever was, I even reinstalled windows, but the card can't handle full speeds at 2d.
Will there be any fix for that?
