Noob OCer here. I have a 3570k at 4.4 GHz and its stable with decent temperatures and is exactly 1.2v at idle which I set it at in BIOS, but during actual loads like P95 the vcore automatically lowers itself to anywhere from 1.13 to 1.15. I am using cpu-z and realtemp. I thought that most people need like at least 1.2v for 4.4GHz so how the hell is my system not crashing at 1.13? I've been using it like this for the past several days and everything is fine except for the high idle voltage and temps. It idles at 35-45 and loads at 65-75.
Mine is i5 2500K oc'd at 4.7 GHZ at 1.44V vCore since December 2011 and I am only using a cooler master hyper 212 plus CPU cooler and very stable in any kind of games. GPU is Asus HD 7770 direct CU. I For as long as you maintain a decent temp inside the chassis(5 120mm fans). Before I forget I am using a Biostar TZ68A+ MB, 16GB DDR3 1600 MHZ. They say with that vCore it will shorten the life span of the CPU, I don't believe them.
