Voltages:
Now let’s move to voltages, this is very important and I think anyone looking to overclock should have a thorough introduction to the variety of voltages that the user is able to control.
Make sure to pay attention to my tid-bits on Vcore(VCC) and VTT(VCCIO), these are most important for overclocking, other voltages can help too.
Here is a table I put together from Intel’s product data sheet; it defines the processors maximum voltages and maximum amperage- These are OFFICIAL Min and Max Values:



VCC: Commonly Called Vcore, the voltage supplied to the processors inside the CPU. This voltage is a large part of Sandy Bridge overclocking. Now from personal testing, and weeks and weeks of headaches and hard ships, I have a few things I would like to share about this voltage.
I say maximum voltage for Vcc/Vcore is 1.50v for 24/7, 1.55-1.60v for extreme benchmarking, please stay below to 1.6, and don’t use any type of Load Line Calibration past 1.55v. Please not that high temperature teamed up with high voltage will kill your processor faster than anything else, it creates a perfect environment for processor degradation.
