Core i7/X58 Overclocking Thread

[NBF]

I need 1.275 VTT for 19x200+HT. I'm actually backed down to 21x180+HT right now though but still at 1.275 VTT because I didn't feel like figuring out if a lower value would work. I required 1.375 VTT for 20x200+HT in Prime blend and I think the bump to 1.395v helped with 21x200+HT.

Your chip seems to react like my 3837B017 regarding QPI and Vcore voltages, also there is some kind of binding between QPI voltage and Vcore, maybe its temperature related.

If you want to try, I got mine stable at 211bclock @1.5VQPI and 213bclock @1.55VQPI.
