It seems that I can clock up to 750 on SC stock voltage (1.012), but anything higher I get artifacts in Kombuster and Heaven 2.0. Temps are in the mid 80's. I'm thinking of pushing the voltage a bit more and try for 800/1600. So, for those who have clocked to 800, what kind of vcore did it take to get you there? It's all good. I can use a little ribbing. It keeps me humble. I may change out the TIM this weekend, and see if doing so will give me a bit more play on the voltage.
