Ok so basically, my e5200 is at around 1.38 volts right now in bios. Intel says 1.365 is the limit(I think?) I just want to know, how high can the voltage go before I really start sacrificing lifespan? I wanted to go for 4ghz, but I dont want it to only last a week at that. Should I just go by temps and make sure I dont go over, say 65C under full load? Or can volts still kill the CPU even though it is not getting very hot? I hope this makes sense, thanks guys.
