980's oc very well due to 32nm but also (in the long run) could be a bit more sensitive to high temps and v's for the
same reason....Intel max v's are vcore and vtt up to 1.4v and cpu pll up to 2v - so you have lots of head room here - provided your cooling can
handle it.

CPU Clock Drive-----------------------------------------[700mV] make 900mv
PCI Express Clock Drive----------------------------[700mV] make 900 mv

What are these 900 mv values based on? I'm just curious. Personal testing? Intel references?

I put these into my system (installed two weeks ago, still trying to find optimal values at stock to make it stable) and the 900 mv values do
appear to increase stability in Prime95.

I'm trying to get my 12GB Kingston 2000 MHz RAM stable at stock BCLK (1866 MHz, effectively, using stock 133 BCLK; 9-9-9-27 timings) and I'm
trying to figure out where the QPI voltage should be. It appears that 1.4v might be a tad too low; I'm occasionally getting errors in the 'blend'
test of Prime95. Although once I put the 900 mv values in the above two spots in the BIOS I haven't encountered another Prime95 error using
1.4v QPI.

What QPI are other users having success with the 980-x, 12GB RAM, and 1600MHz+ RAM speeds?
