@ krampak: You can't pass this fsb on Qs.....They all have too low fsb....
I've seen only one or two of them going even over 400MHz fsb....
Gorillakos' Q6700 can do 365MHz on air (and we will see under subzero cooling) on an ASUS Striker mobo
Oh... wait... you say it's a QX67000 LIMIT ? I tought It was only a DFI RD600 limitation.

Wel... I've reached 450Mhz FSB on my QX6700 ! Using the Asus Commando



It was 3d stable at 430.
