Okay guys, a few days ago I assembled my system which consists of a Q6600 G0, 4gb OCZ Flexxlc9200, and a Blitz formula motherboard.
I have been tweaking and looking here at the forums to find good bios-settings.
This is what I managed to get so far:

The thing is that these settings isn't so optimized. I only get 13.4s in super pi (Or is that good @ 3,8ghz?)

Oh well, thought you could give me some advices of how to reach even higher speeds.

I get these temperatures with my watercooling at 3,5ghz and 1,4 - 1,45vcore and with a normal ambient temperature.
