What is the difference between them? Just need some clarification between them and the pupose of each. I need a fair bit of juice to overclock this CPU. It's a OCing POS. But noticed this motherboard vcore fluctuates alot compared to my old motherboard. The core will fluctuate from 1.45v-1.49v atm with the settings I have it at. This is how I have the settings at the moment to keep the 2.6Ghz OC stable. 1.45v VID control +40mV vcore.
