CPU is 3 years old, I have been overclocking a lot in the past. CPU is running off a ASUS z77 motherboard.
After running CPU on standard clock for some time, yesterday I tried to OC. Initially I tried 4.3GHz (which I have gotten just fine before). I got the "Overclocking Failed!, only when going to default clock was I allowed to boot.
When booting W10 with standard clock I got BSOD while loading windows: WHEA_UNCORRECTABLE_ERROR
When booting Ubuntu (dualboot) I got this: http://i.imgur.com/kSMemDS.jpg
I had to go all the way down to 2.7GHz to get it stable.
When 2.7GHz prime95 testing yields no faults (no BSOD, no overheating).
Any Ideas why I am able to use it at a low clock, but not standard? Anything I can do to improve the situation?
If language or phrasing is poor, ask and I will clarify. I am not a native English speaker.
