CPU volts, or NB volts, ram volts, or ram timing? I think I can make this system stable and I will be very happy with 3.9GHz! TIA
You should use some dedicated software to adjust your OC rather than a game. A game is ok for benching, but not for finding your stable OC

Use Prime95 small FFT to check your vcore is ok or no, and OCCT RAM to see if your NB and RAM are way too stressed. Small FFT or OCCT CPU mode first, once your vcore found, set it a notch or two above the limit found, get OCCT RAM stable, than maybe begin lowering your vcore vPLL to find the real lowest stable value

Good luck, you'll be the first to get a stable 3.9GHz Q6600
