I've run into some issues with my overclock. I decided to take the cpu cooler off to check the TIM was applied properly. I then took the cpu off and carefully cleaned it and and the cooler. I reseated the cpu and attached the cooler tried to turn on but kept getting a bios error, which the came down to the fact I accidently hit one of the auto overclock buttons that's attached to the board. I disabled the setting and when I restarted the pc I reloaded the 4.7 ghz settings I used previously. On these settings it lasted 24 hours on a test but now with the exact same bios settings it wont last 30 mins :/ and its not the temps because if anything they are even better now. I am completely baffled because when I increase the voltage now, the test runs for a longer period of time which gives the impression it needs more voltage......
