*Official Retail G0 Q6600 Overclocking Thread*

Raising NB Voltage can help you with the higher FSB clock.

Raising VTT can help you lower your Vcore once you get a more or less stable voltage. It's also called FSB Termination Voltage since it's related to the FSB...

System Bus Input Supply Voltage, often referenced as FSB termination voltage (VFSB) simply the voltage the fsb is running on. logic levels on the fsb are relative to this voltage. higher vtt results in higher logiclevels and thus in increased noise ratios. increasing vtt might help overclocking.

...But I had actually confused it with PLL, so it might not be as important for your overclock

My next step on the NB voltage from 1.29 is 1.33.. at 1.29 the NB heatsink is so hot that I cant keep my fingers on it for more than 2 seconds.

My VTT increase is bound to the NB voltage.

[Zayras]

Heh, in that case you might not want to raise the voltage. Also, some chips can't do 3.6GHz (that's a 50% overclock after all). Mine needs a lot of voltage to stay at 3.6GHz (more than 1.5V, but then again my chip's VID is 1.325)

My NB voltage goes up to 1.5V I believe, but I also believe Gigabyte has some pretty good heatsinks on this mobo

[Demo]

IIRC, my VID is also 1.325.. Would you happen to know if 378FSBx9 or 400x8 would perform better, thats 3.2Ghz vs 3.4Ghz.

[Zayras]

Well, 378x9 would be a lower FSB, which means less heat for your mobo.

400x8 means higher FSB and certain programs might benefit from that, but I believe overall you would see more performance with the extra 200MHz on the CPU.

[Demo]

Im getting mixed results with different games though, its a 50-50 on the result, I guess ill settle with the one that requires lesser voltage.

Great! Had this one too... mine did 3.92 ghz max on IP35E :p
