I see a lot online about what the actual safe max voltages are. The variance in opinion vs fact is so great, I just decided to pick something in the middle and go for it..lol.. This is what it seems was necessary to hit 4.4 stable, with occt, memtest, 3dm6, vantage, 11, heaven, and playing games.. "so far" lol. I'm not to sure about the QPI and the IOH @ 1.5 v I placed down there, but I read the IOH could add to stability and it hasn't hurt me so far. I'm open for suggestions on that and may very well lower them back to stock 1.1v. Oh your going to want at least a "very good" air cooling for this. I'm running the scythe mugen 2 and I still hit 90+c at 100% load. But the truth is, I never hit anywhere near 100% load, so I'm not even worried about it.. Average is around 70c gaming I suppose, 49c idle. I also run my Visiontek 5850 @1.299v 965/1100. 120mhz on the pcie in bios. EDIT: Weeks later and still stable.
