How do I increase my bus speed with this motherboard?

I have a Asus p5n-d. Running a Q6600. How do I set the bus speed to 333?

Is it the FSB setting which is not 1033? This is killing me, not to fond of this BIOS

If you don't have a copy of your motherboard manual I would recommend downloading one from Asus. Read through the section on the BIOS thoroughly, I'm pretty sure it explains the settings in there.
