Some overclocking help needed

[Wizardskills]

Hi Guys

I'm looking to overclock my q6600 to around 3.2 Ghz and i am not to sure how to go about it. I have never overclocked a cpu before (until last night) and am in need of some advice. I have read over the sticky at the top of this page and have looked round at some stuff on the net.

At the moment i have my CPU set at 300 x 9 so 2.7Ghz. This idles at 37~39 *C and up to 53 *C when i start SETI@Home running. I left seti running last night only to find that my comp had crashed out so i don't think it is to stable atm. I haven't altered any of the voltages yet and i am guessing i am going to have to to get a higher speed.

I have also seen on the net some people lowering the multiplier down to 7 or 8. Why is this? So the FSB can be increased more without affecting the chips temp as much?

Also when i was in the bios i could choose between linked and unlinked overclocking. Now i think linked clocking increases the RAM FSB, however is it wise doing this as mine is only rated at PC6400 speed.

On the subject of RAM mine is rated at 4-4-4-12 according to CPU-Z

But is only running at 5-5-5-18

How would i go about changing this?

Any help would be greatly appreciated

Thanks

Ok, i now have the cpu running at 3 GHz (333 * 9) with 1.37 volts and it seems to be stable (if it is still going in the morning then it is fine ). Temps seem to be ok, around 40 *C idle and 57 *C load. How high can a q6600 B3 go on air?

Ok i have it running stable at 3 GHz with 1.4 volts. However when i put my RAM at 4-4-4-12 with 2.1 volts it all goes to pot and crashes all the time
