Guys, I have tried a 3930K and a 3960X in my R4E and even though both were confirmed decent clockers I am having great troubles with this rig. At this point I have the 3930K in with 3101 bios, at stock clocks its showing vid of 1.326v, cpu-z is showing 1.312v at idle and 1.288v while priming. I have tested with a DMM and confirmed 1.288 measured volts while priming. I have to set vcore manually to 1.35v to get it stable at 4.4ghz but the last owned (who is known to me, fellow OCAU member) could get 4.7-4.8 ghz at those volts. He has benchmarks at 5300 on water, I am never going to get anywhere near that as it is. I know results vary etc etc but that much? My last 2011 rig - 3930K on an R4F could prime 4500 at 1.250v, this rig is a let down. I also have a 3960X that is suffering the same symptoms on this motherboard, is the mobo stuffed? Bios update didnt help at all.

Any help would be great.

:-(
