Hey Ket Im sure if you new how or could find it you would of mentioned it but ...

Is there anything in the bios on the P5Q pro that would limit the FSB to 500? Is there any hardware trick that they do to limit the fsb to 500?

Just seems kind of odd to me that the pro's are all (or pretty much all) limited to exactly 490 to 505 fsb. Wish they would not have locked them or whatever they did to keep them from going higher, seems like a good board otherwise.
