Have an Xeon X3350 (Q9450) on on its way here, but first I need to one thing

Going to use my current Pentium D 920 on my P5B Deluxe to update BIOS to 1226 (newest).
Since the new Q9450 is C1 stepping NOT C0 I'm not sure if it will work on my motherboard.

Did anyone see any report of CPU being damaged/killed due to BIOS not supporting the CPU?

Overclocking is not a concern for the time being, just want to get it up and running

Cheers
Arthur
