That is the board in your sig at least, so I assume you are referring to it.
Sorry ignore my sig, it's out of date. I'm running the P5W64-WS Pro now with 0116 BIOS (one it was shipped with) and the multiplier ratio is greyed out in the BIOS like it is on the P5W-DH (at least before the latest beta P5W-DH BIOS).

I already know how to change the multiplier with CrystalCPUID - but it seems if you can get the board (ANY of the boards) to boot with 400+ BIOS then it seems to be using a different strap (1333 instead of 1066). I desperately need to know how the OP managed to change the multiplier to *BOOT* at 6x450.....
