ok so i managed to oveclock my amd fx 6300 to 4.2ghz with 1.3V and after running prime 95 for an hour temps were stuck at 51C so i just stopped it seeing it was good enough. i want to push it to a final 4.5ghz, so what voltage do you guys reccomend? 1.35? 1.38? under stress my voltage bumps itself up a little so at 1.3V it was running at 1.32 under prime95 under stress
