Well I almost did it. Just over 4GHz with 1.416v seems stable running F@H. For some reason F@H seems to be a better stability tester than prime95 as I would pass prime for several hours but then fail and lock up in F@H after an hour or so. Anyways temps jumped up about 5c so up to 50c socket and 44c core I may downclock to 3.8 come summer time. Unless I can invest into a proper water cooling loop.
