What is the stock vcore? In the motherboard sometimes it shows 1.26xxx, sometimes it shows 1.28xxx as normal value, and setting is auto.
Bus Speed - 190
QPI Link - 3415
My Core Voltage = 1.35v
I think stock voltage is 1.25v
Remember to unlink your memory and turn off any turbo features, speedstep and power saving features as at this speed it is unnecessary.
My temps at idle are: 38C, 41C, 39C, 39C and don't go over 65C on full load with any core.
