Cant overclock G0 q6600 to 2.8 even at 1.5V!

post #1 of 16
Thread Starter 
Well, in fact, it will OC to that even with a lower voltage. I can run stability test and will work (at least for the first minutes, haven't tried a 24hs test), however, as soon as a 3D game (say COD black ops) start, instant crash occurs. I obviously thought it was because of voltages drops, but if i do the same without CPU oc'ed and monitor voltages they don't drop any more than they use with a stability test.

Also note that I have huge vdroop (0.1v)

Mem clock is stock (I chose unlinked) if that's what you mean.

I never understood, which would be the difference from lowering multiplier and highering FSB if it is unlinked?

And about the chipset, it might suck, but still, I see everyone OCing this micro up to 3.6 with air, I feel like crap not reaching even 2.8 using much higher voltages than them. Also, with 1.5V (its 1.28 stock or 1.3 don't remember) I still get pretty good temps, so it really makes me want to OC

It's the board man. I still have one. It is one of the worst boards for overclocking a Q6600. It did well with my e4500. There is a huge thread in the archives on that board.
The highest I got my Q6600 was 2.9.
You may find some useful tips in that thread.

Now I check, I never modified NB voltage, maybe thats the cause. How do I know how much should I put? Because I don't know the default value (it says just auto)
