3942A***** , does 4.0GHz on 1.2v Prime95 stable (2h) outside chassi and with a Scythe mini-ninja with two 1200rpm push/pull fans giving a max temp of 70c. Did take me a while to find out how to oc the i7 architechture, coming from core2. Once I got hang of qpi and pll importnace my voltage could be reduced from 1.35 to 1.2v. I'ts mounted on a MSI X598M board together with 6 Mushkin 1600MHz sticks. Board does 225 BCLK with mem slots fully occupied, very nice board for that price! Gonna drop a better cooler on it and se what we can do. Is there any need for lapping the i7 cpus? My old q9300 dropped 8c when giving it a overhaul with 1200 paper...
