Anyone undervolting just with a negative offset rather than using manual? If so what's working for you?
I did an offset undervolt this weekend. I am running i7-6700k with the c7 heatsink+noctua fan.
Set the multiplier to 39 with baseclock of 100. Turbo mode disabled.
My stock voltage was 1.280 and I am now runing with offset -0.130 and everything is fine so far.
Have not yet done any real testing except for a 6 minute CPU-Z stress test and from this i saw 5 C lower temps. But this is still unconclusive until I've done some better testing.
