well I tried Ai Clock Twister Moderate & Light going one notch higher on all the voltages with no success at 460FSB I didn't seem to have changed anything since my everest scores were roughly the same as at Ai Clock Twister Strong, which I found strange. I thought that would take some strain off the NB, maybe I am wrong & the PL is causing all this.

I will try another round with higher CPU & NB Skew delays lets hope that helps...
Lets hope that is the answer to my FSB wall.
