I have the same mobo that you do and playing in the bios as I usually do with a new board the only thing I saw was the burn in option for +4%. When I get back to my computer, I'm going to max the burn in mode and ramp the FSB as much as possible while tightening my CAS latency. I'm thinking I'll see a fair increase in performance without having to go out and buy a new chip. If you have the money, get another board that has more room for OC, otherwise stick with what you have a pump it as much as you can.
