I benchmark OC with 3dmark vantage. Sometimes, I can run a loop of the tests for 5 hours with a certain overclock, its fine. Then I go to play a game the next day with what I thought was the best OC I could use, and it doesn't work (errors in game, cut to desktop, driver not working, like you)
This might mean it's game specific. Some games error out at low OC, some don't give a damn.
oh ok.. thanks.. will clock on default..
thank you all
