Opteron Overclocking

[KWJay]

Just a quick question here guys. I've recently changed my cpu to an Opty that is far more reliable and more overclockable than the old one. I was just wondering if i would see more performance running 1:1 with my memory, which i can to about 2.67Ghz, or would i see better returns running with a divider and higher cpu speed? I can get to at least 2.8 on a divider btw.

Thanks in advance for your help!

Unfortunately the mem i have doesn't like running at anything under C3, which it will do all the way up to just under 270FSB. So the divider and higher cpu speed would be better than the bandwith of 1:1?
