Hello,
I have a MSI X79A-GD65 (8D) and a i7-3930k. When I got it I started OCing it to see how high i could get. I was able to achieve 4.8GHz @ 1.425V and finally stopped when I got to 5.0GHz @ 1.5V.
I decided to make my 24/7 OC to be 3.8GHz at 1.250V (running prime95 it would teter out at 57C). All was fine for a couple days but now things have deteriorated. If I try to overclock at all the system hangs at the win7 logo screen during boot. The stock 6-core turbo boost is 3.5GHz. Even if I just change that toe 3.6GHz the system freezes during boot. It does not matter how high I set the voltage. About 1 out of 5 boots its a success. When it does boot, everything runs perfectly. No stability problems. I'm clueless.
Even though it is the norm with SB to simply increase the Turbo Boost max frequency, one should still be able to simply turn off speed step and turbo boost and set a constant frequency. If I set a constant frequency above 3.5GHz though, I run into a new problem. It boot, but the cpu speed is set to 1.2GHz and the cpu temp readings are constant at 91C, even though there is no way it was ever that hot. If i open CoreTemp it reads "91C?".
Any help would be great. Thanks
Rest of my system:
Tuniq Ripper 1000W
G. Skill Ripjaws Z series DDR3 1600 4x4GB
MSI GTX 580 Lightning
Corsair H80
