Alright, so I recently bought an h60 liquid cooler and decided to OC my 4770K to 4.2 GHz. I did a stress test on Prime95. After about 1 hour 20 mins, my computer gave me the blue screen with a 'WHEA_UNCORRECTABLE_ERROR' message (windows 8.1).
I logged the test. For the entire duration (1 hr 20 mins) my Vcore averaged 1.275v. Is this too high for a 4.2GHz OC? Also, my core temps averaged from 65 - 70 C for the entire duration of the test. At some points, temps did hit 92 C but briefly.
