Driver has stopped working

[avto]

i OC my r9 280 from 980 core clock to 1200. I ran Valley benchmark for 2 hours and nothing happed everything was fine. But now  i decided to play BF4 after a long time. 15min in to the game screen freezes and i get notification: AMD driver has stopped working and successfully recovered. Now i dont know what is the problem is it the game, AMD drivers or my gpu. I didnt played BF4 for a long time because i got this notification before about 2 months ago when i played without any OC

GPU OC is the problem, dial it down a bit and  stress test it again.

The only true way to stress test a GPU overclock is with games, Valley just doesn't cut it.

but it doesnt fail on strees test only in game and it failed in the game before th OC to

 

one more question why is my core voltage 1250mv while benchmarking if i have it set by default on 1125mv

Probably the voltage regulation is on adaptative or the software is being a dork. Plus, I want to say that 1125mV is not going to cut it for that kinda of overclock. 1250mV is more realist
