CPU GTL Voltage Reference (1/3): 0.670

0/2 = Core number 0 and 2 ?
1/3 = Core number 1 and 3 ?

0.670 on both will put the same amount of voltage on every core?

The core2 from my Q6600 (core0/core1/core2/core3) gets constant error in prime95 and i always need to raise up the vcore to get that core stable, although i think the others core0,1 and 3 they all are pretty stable with lower vcore value.

I have move the GTL VR (0/2) from 0.630 to 0.670, and it seems i can get more overclock with less vcore. Is it ok? changing from 0.630 to 0.670 will not kill my cpu?
0/2 & 1/3 have nothing to do with the individual cores. They denote BCCLK 0/2 & 1/3. Raising it to 0.67x is fine just keep your Vtt under 1.4v. You want to aim for a target Vref of between around 0.8 - 1.0v.

GTL Ref (the multiplier eg 0.67x) x Vtt = Vref
