I found that I was forced to redo my gpu OC after I had OC'd the cpu. Save yourself a little time and do your gpu OC when you have found and set your stable cpu OC , less time messing around and more time gaming

I run a couple of game servers out of Red Deer, 1 for Fear and 1 for COD4, come by and test your settings if you want, they are 24/7
