What should my core voltage be?

What should the voltage for my Intel Q6600 Quad-Core processor be? The processor is a G0 stepping and right now, the BIOS for my EVGA 680i motherboard, in the voltages section states that the processor is getting 1.4 volts, should it be lower? I do have a modest overclock from the stock speed of 2.4g to 2.8.
coretemp says that the core VID for this processor is 1.275 so to me 1.4 volts seems to be a bit much.
I am thining that if I can safely lower the core voltage from the stock 1.4 to a lower value I can lower my temps a bit, does this make sence?

Thanks fellas

at stock speeds, set it to 1.275V

If you're overclocking, 1.40V (in BIOS, it should be lower in CPU-Z) is fine

"stock speeds" should be what your VID is (you'll probably want to increase it 2-3 notches in your bios to hit your VID due to vdroop) so for example if youre VID is 1.25 set it to 1.3 in bios and load up your cores to see your vdroop in cpu-Z and make sure its aroud 1.25. this means you're running your cpu at its stock speeds.

1.4vcore is pretty high for a 2.8ghz overclock.

my CPU-Z reads 1.232vCore and my OC is 400 x 8 = 3.2ghz. i think its set to 1.275 or 1.3 in bios

I could not get a stable overclock of my q6600 at 3.2ghz until I hit 1.46v in my bios. CPU-z has it at 1.42. Mine is go stepping too but I think I just have a processor that just needs the extra juice

There's no way for us to tell you how much voltage your processor needs, but it's likely that you don't need 1.4V just for 2.8GHz. Lower your voltage and stress test until your CPU is no longer stable, and then bump the voltage back up a notch. Stress test again, and if it passes, you're good to go.

People have different opinions about how long something like Prime95 needs to be run. Since I've seen errors show up after six or seven hours, I always run it at least overnight. Some people even go 24 or 48 hours before they call it stable, but that's probably not necessary for the average user.
