Hey, So a few weeks ago I upgraded my computer, The parts I replaced where

fx-6100 3.3ghz
Cooler master 212 evo R2 2x120mm
Asus m5a97 evo
2x8 GB GSkill sniper 1600 cas 9
vertex 3 120Gb
6870 sapphire

old
625 watt enermax pro 82+
storm enforcer case
2x 1tb Hd
dvd burner

So I have tried everything I can think of and read but no matter what I do I cant get the cpu stable past 4.2 ghz. Everythigng Ive read says at LEAST 4.4-4.5. Every power saving thing is disabled and everything else is stock except the cpu mulitplyer and voltage. The stock voltage is 1.275. To get it stable it needs 1.368 - 1.39 to get prime 95 stable for about 5 hours before it fails. Even then no matter what voltage I feed it its not stable past 4.2ghz it either has a hardware faiure on core 5-6 or freezes the computer. Does anyone have an idea? core temps are around 49-50 running prime 95
