Hey I have a Asus P5N-E SLI and a q6600. My 4x1GB OCZ DDR 800 sticks are running at 2.1 volts because I know that that's safe and recommened. But I am having stability issues with the rest of my system. My PSU is OCZ 800W Xtreme and its almost brand new so PSU isn't the problem. So I need to up my voltage on my northbridge and core. I can easily achieve 3.0 Ghz but sometimes it does crash. My q6600 isn't overheating and I have lots of room to overclock yet with the temps I'm recieving. So I just need some advice at what to set my voltages at on my mobo. I would like to see if I can get my q6600 to like 3.3 ghz or even a stable 3.0 ghz.
