So I upped the volts and everything looked great for about 5 minutes then it froze. Didn't fail, just froze up my whole pc. Now I think its my ram. I have tried increasing the volts, raising and lowering the frequency, and loosening the timings but now it always freezes up. I can understand a core failing but my pc isn't suposed to freeze up. Any suggestions?

Q9400 could hit 3.0Ghz without any voltage increase... when I had mine, I would hit 3.6Ghz with 1.315v (gigabyte P45). Prime & OCCT stable.
