u mean CPU-Z show ur CPU voltage at 1.39? it cant be so high,wif 1.39 V, i can do 3.4ghz i think. ur CPU vcore set auto in motherboard BIOS is it??for mine,if 3.0ghz, i set at 1.2625V, 3.2Ghz at 1.31V at bios.

if u're using stock cooler, suggest u change it. most ppl wif Q6600 dont use stock cooler as the proc is so hot.oh yea, if u're doing 3.2Ghz, suggest u do 400X8 set up instead of 354X9.reason is,wif 400X8 setup, u get 1600FSB. for quads,its actually 2 core2duo fitted in a package call core2quad. these 2 core2duo proc communicate wif each other through ur FSB. so i think higher FSB does benefit the quad more. and 400 FSB dun need to bump NB and VTT voltage yet.i'm using the 400X8 setup and its stable for 50 rounds of IBT.
