I have a p2b also and is trying to run my cel 633 at 950. I'm having trouble with it booting. If you've got yours going, let me know how. I've tried both the 1012 and 1013 bios. Also using an msi6905 slocket. It seems to be stable at 712 only. Thanks >>
For me, downloading/upgrading to the
1013.5 beta bios from Asus, and then setting my voltage to 1.8 and my speed to 100 on board and on the MSI Master slocket worked. (I'm also using a huge HS/Fan on the processor.)
Anything less than 1.8, and v5 of the 1013 bios, and my P2B just wouldn't boot.
But it sounds to me from your comment about it being stable at 712, that the problem isn't getting the chip to work per se, but to overclock successfully.
And that opens up an entirely different can of worms, but... a few steps that I've heard have been successful -
1. Better HS/Fan - Intel HS/Fans are good for normal use, but I've found they don't quite cut it when overclocking. Try a good aftermarket version.
2. Raise the voltage - 1.9v seems to be the highest most are willing to go, according to the
Overclockers.com database.
3. Try a different slocket
OR accept the fact that your chip may just not take well to being overclocked.

4. Lapping the CPU -
Definitely not something I'd recommend, although it has been done.
