Well i seem to have found some more performance.

I have managed to...
Prime for 8hrs small FFT at 4.3 (1.45 vcore)
Run SuperPi 1M at 4.7 (1.525 vcore

This is all with fairly basic water cooling doing cpu, 2xgpu's and the chipset.

Looks like my chip is a very good one. It was the motherboard holding me back. More Nbridge volts required and less everything else.
