I can't get my 920 past 3.6ghz before it comes unstable. I've changed ram multiplier down to 6x, tried all type of voltages on vcore, ram and vtt, nothing works. The cpu temp under prime95 @ 3.8ghz doesn't get to 67c before it crashes so would I be right in guessing the problem is either the ram or chipset that's overheating? I have a bog standard coolermaster elite case with just the exhaust fan. Thanks for any help.
