Hey there 
I have tried to overclock my GPU just a little bit in the AMD Overdrive in the Catalyst Control Center and ran the Valley Benchmark. It was running pretty smooth, a bit better than usual, temps were stable and than a yellow screen showed up. Just a yellow striped screen, although the song in the benchmark was still running. Couldn't do anything, had to restart my PC and I've put the settings to default again.
I've overclocked both GPU and Memory clock a 50MHz up and put the power limit settings to 10%.
Any ideas what could have cause the problem? I think that if I even overclock it for 5MHz I'd still get the yellow striped screen... :/
Thanks in advance 😀
