Hi all.
I am running a 4770K at stock clock with an Corsair H100i. I got the WHEA_UNCONTROLLABLE-ERROR in Windows 8.1 a couple of times before disabling Intel C-state and EIST. I ran the blend test for Prime 95 and it was fine. I then played Far Cry 3 for an hour and to my horror it happened again. I then re-booted and ran all of the prime 95 tests and I got no errors, I've also run Uningine Valley with no errors. The average temp is also around 80 degrees now even while idleing?
Any ideas?
