I just got a my Gigabyte 7950 a few days ago and just wanted to try OCing with CCC and so I turn on overdrive, crank it up to 1000/1500 and the +20% power and it passes GPU benchmarks and heaven but when I play DayZ for a while the game crashes and I get a beep, but it doesn't do it when I just revert to stock 900mhz. So what exactly is the problem here?
