If the Northbridge can clock up to 6200Mhz... what's holding the core frequency back?
I thought that too much frequency at the northbridge was the problem, and thats why we were using dividers... but now I don't get it... even 3Ghz core clock is hard to get working.

No. The problem is the Phenom chip itself.
