Im just asking because im curious after reading about 6600k oc.. My 6600k have been oc'ed to 4.7ghz for quite a while now, before 4.6. Vcore on 4.6 was 1.26. Now i just run 4.7 at 1.3v because its the setting it loads up in. But its stable under 1.3v. Reason i dont bother test that much is that i have no problems with temps and its stable. Dont want to fix anything thats not broken. But i had no problem running in 1.27v when tweaking in msi commandcenter when i tried that couple of times.. Havent tried under. But, how is 4.7ghz or higher with a vcore around 1.3 or under? I havent tried clocking it over, yet. Dont see any reason why at the moment. Even tho i need to test it to see how far it will go in the future.
