Your cpu fraquency is the FSB x whatever the cpu multiplier is.
If you have a 400fsb with an 8 multiplier your chip is running at 3.2ghz.
The general rule of thumb is to leave the voltage stock while increasing the fsb by small incriments ( 2-5mhz at a time max ) and then running benchmarks to test stability. Then just repeat this process untill you fail a bench or start getting faults or crashes.
When this happens try increasing the core voltage by .01 until it either fixes the problem or you increase it by .10 ( 10 notches ) whichever comes first. If your board only has settings like 1.30, 1.325, 1.35 etc and doesnt allow .01 adjustments just try the next level above what the stock value is and dont go any higher.
If the voltage doesnt fix the problems try the ram. Either by running a divider ( 5:4 instead of 1:1 etc ) this will allow you to keep upping the cpu without the ram being a possible limiting factor for the fsb. loosening the timings or using a 2t command rate.
1:1 refers to the ram and cpu being at a 1:1 ratio. For example. If you have a 400fsb and the ram ratio is set to 1:1 then the ram is running at ddr2 800 ( ddr = double data rate = 400mhz x2 = ddr2 800 . This works in a linear fashion.
If none of that helps then you found the max for your particular chip.

Or motherboard.
You're right, the Q6600 has a 9x multiplier. The only quad-core I know of with only an 8x multiplier from Intel is the Xeon X3210, which is basically a Q6600 with a slightly lower multiplier and a slightly cheaper price. One final thing you need to keep in mind is that you should have something better than the stock HSF if you want a good overclock. (Right now, my stock HSF temps with AS5 are between 47-54° C just IDLING...I would imagine that load temps would be in the 60-70° C range. And this is on STOCK CLOCK SPEEDS...I really need to go out and buy a Thermalright Ultima-90 already, or something to help alleviate this...q6600 shld have 9x not 8x i suppose.
