I spent a couple hours last night tampering with my windforce gtx 770 in evga precision x and brought my heaven benchmark from 975 to 1015. I removed the overlcock, and this morning the stock settings only get a 935! What could be the issue here? I didn't change any voltages, and the temp stayed below 70 the entire time. I should also mention that it did crash one or twice when I went too far with the core clock. Thanks for any input!
