R9 Fury Overclock too high?

[Anheanz]

I have a sapphire R9 Fury which i tried to overclock to 1125 Mhz with +18mV and a power limit of +20%.
Also an i7- 4790k not overclocked.

The issue is when I try to play Witcher 3 I get solid fps around 60-65 and then the screen will just go black and I cannot escape the game or get to desktop so I am left to reset. There is no stuttering or other issues before the screen goes blank, and it is not happening only in action sequences, it is completely random.

Could this be caused by the overclock? Also, are these settings good? This is my first time trying to overclock anything so i'm not sure how high I can raise voltage/power limit.

Thanks

you can raise the voltage more, even +30 is fine. that is most likely a crash, so yes, either dial back the clocks, or raise the voltage. those numbers seem pretty decent. that card does not seem to be the most splendid overclocker.
