Fair enough, perhaps it is something else holding him back. It was simply a suggestion to attempt to alleviate his issues, only him testing it can determine what is holding him back. However I have never run a quad on this board, so I don't know from personal experience what vNB is required for them to hit 450 - 500 FSB. Thanks for your input.

I have hit 590FSB on only 1.26v vNB so I wouldn't think it would be an issue for him but just suggested he bump it up to eliminate it as a possibility.
