I tried many clock settings and none will work above 333MHz x 9 for the Q6600 CPU. Interesting enough I had an E6400 at 3.2 (8x400MHz). So it has to be an Q6660 + P5W DH issue
I don't know why but with the quads, the P5W DH won't allow you a high FSB.

If I tough the northbridge it's very hot so that could be the reason (having to handle more I/O requests due to more cores).

It will do 333MHz though giving 1333MHz effective, even without bumping up the voltage.
