Help with OC'ing Q9550/Rampage Formula

I'm still rather confused about what changes I have to make to the default BIOS. I'm using watercooling for my CPU (and GPU) so I don't worry about heat to much.

So far I've got:
- FSB speed
- CPU external clock multiplier
- Memory timing

Intel Core 2 Quad Q9550 Yorkfield 2.83GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor

ASUS RAMPAGE FORMULA LGA 775 Intel X48 ATX Intel Motherboard

Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 996580

Allow me to think out loud here

FSB: I have DDR2 800 Dual Channel RAM so I should run up to 400 MHz FSB whilst the MoBo supports 400 MHz (=1600/4), the CPU is set to 333 MHz (=1333/4) as standart but should run 400 MHz just fine

The CPU external clock multiplier is locked at 8.5 so if I'm going beyond 8.5 x 400 MHZ = 3.4 GHz I'll have to push the FSB beyond 400 MHZ

So I checked the BIOS and it lets me choose a FSB from 200-800 MHz but I can't choose the voltage. Is the voltage regulated automatically to meet the power needs of the system settings or am I missing something?
