The Intel spec sheet says 1.4V. I personally run mine @ 1.45V as I have read a lot of people get no degradation using that limit on 980x.

Depends on cooling, really.

If you want to be 100% completely safe, cap it at 1.375v.
For air, 1.4v.
For GOOD air or water, 1.45v max.
For chilled or subzero, you probably won't care very much about the volts.

Intel lists "absolute maximum" as 1.4v according to the datasheets on their site..

my next question would be the ram sure its rated for 2000mhz but the timings are 9-10-9-27 2t vs my 1760mhz 9-9-9-25 1t. i heard somewhere that 1t is faster than 2t. is this true?
