What should I have my G.Skill HZ set to in Bios?

[NokkonWud]

I have the G.Skill 2GB DDR2 HZ PC2-6400 RAM and was wondering what speed it should be set to in the BIOS of my Asus P5W DH Deluxe motherboard?

on the Everest benchmarks it's being read as:
Core 2 Duo E6600 3066 MHz Asus P5W DH Deluxe i975X Dual DDR2-681 5-4-4-15

Any help on any settings that need changing would be appreciated.

This is probably gonna sound idiotic, but where the hell is the divider? It's currently set to 9, I take it you want me to drop it to 8, but there's no visable option.

Yes, I'm fairly new to overclocking, especially with ASUS boards and it's confuzzled me. I see all the other options bar the multiplier.
