I manage to OC my i5 6600k to 4.6GHZ at 1.29V and stressed it for 2 hours with Prime95 and then 1 hour with RealBench no issue found (no crash or something).Played some games after (GTA V,Rise Of Tomb Raider) for 12 consecutive hours (some breaks to eat) the temps of CPU in game are 50-55C.
I talked with some friends they said my chip is very good. I wonder with this voltage i risk reduce the life of my CPU ? If no i go 1.33-35 to 4.8ghz i already booted in windows with 4.7ghz 1.31V runnig some stress tests. Any suggestion accepted thanks
