I think I have my northbridge set at 1.525v in my bios. I upped my VTT or FSB voltage to 1.425v. It passed Super Pi 32M and 3DMark06 without any problems. I do not waste much time with Prime95 (overkill)anymore. I think 32M of Pi is plenty stable.

Anybody have any limits on what the FSB voltage should top out at? My MSI board has slightly less elaborate heatpipe cooling than the Platinum P35 but I think the results are about equal minus a few extras like firewire and SPDIF.

Can the Q6600's with 1.2VID's go to 4Ghz on air?

I think You can lower all mobo voltages a bit.

Right, NBF. The NB volts are dependent on memory size/speed, DIMM config, and FSB. I am running 1gbX4 that needs > 2gbX2>1 gbX2. And yes we may be running higher volts then the minium required. ( My FSB 1.44, NB 1.55 vDIMM 1.98) Just the hassle of testing and retesting for as low as possible. Depends howmuch playtime you have. If the temps are reasonable and OC is rock stable I tend to not mess with it.
