Asus P5N73-AM won't boot w/ 45nm CPUs, but will boot Celeron D....

Weird issue with this board. I don't think it's RMA-able due to it booting up, but not with a 45nm Core2duo (e7400) CPU or Pentium Dual Core CPU (e2180), yet the motherboard boots up fine with a Celeron D (any flavor).

It has the latest BIOS... gonna try downgrading the version and see if that helps....

CPU spec list says 0401...

It has 0602, and I just tried it with 0501. They came from the factory with 0401 originally.

It's gonna get sent back to Asus anyway...
