You need an unlocked CPU like a ES to do that m8.
400mhz FSB (Intel Quad Pumped = 1600mhz FSB) x 9 Multi = 3600mhz which is what you would be dreaming of.
try a LITTLE overclock first before you try and jumpt straight to 3.6 !!!! You sound like you don't have much experience of this.
Take some time and read some overclocking guides before you blow up your chip and you have to spend anouther £155 to get a new Q6600.
i.e. Try setting either 280 * 9 or 300 *9 (if multi is 9 on that chip). You may also need to up the voltage of the cpu but I would not recommend playing with that until you've read a good guide, since you sound like you will just set the maximum voltage possible and melt your motherboard along with the chip given how gung-ho you seem already.

There is FSB Holes in the Bios's esp for Quads but 1303 is the best, so you need run bellow or above these FSB Holes.
But lower your Multi and try find your MAX FSB 1st, dont go straight to 3.6GHZ with a 9x Multi lol.
Many thanks - almost got it up to 3.0GHz now by raising the FSB to 1334. It's getting a bit warm so I now need to look into rasing some of the voltages.
Use this to check temps and volts http://downloads.guru3d.com/download.php?det=1797 this is also a must http://downloads.guru3d.com/download.php?det=1340 your temps are fine dont worry.
