Boinx -> RE: Black screen system crash (12/19/2013 10:40:39 AM)

I tried -50% power, -58% GPU clock, -60 mem clock, and 75% max fan speed the first time. That's the minimum I could set in OverDrive through the Catalyst Control Center. I tried -30% power, -30% GPU clock, 0 mem clock (default), and 75% max fan speed the second time. It was working fine until I had to quit. That second test gives me pretty strong confidence that I just have an R9 290 unable to run at stock speeds without locking up. Finding out what clock speeds are stable is just trial and error. Every card will be different, even if they are the same model number and manufacturer.
