Is it a 90nm die Pentium D?
Asus says it supports a 65nm:
Intel? Core2 Duo/65nm Pentium D/Pentium 4/Celeron CPU

>>  2.50GHz - Core 45nm Pentium Dual Core

Don't see that one, but it probably still isn't listed in the updated. Did the new bios say anything about 45nm cpu support?

I don't think 45nm processors are supported - they are too recent and this motherboard is somewhat old.  A problem is that Intel started naming their low end Core2 Duo processors Dual Core, or DC (the E2xx series, for example), which is what the the Pentium D series was called years ago - they are not the same.  This creates confusion when looking at motherboard specs because you may not know which series is being referred to, and the two are not compatible.  I recently tried a 45-nm E8400 in an MSI P6N, and it didn't work, though the spec said it should.

Thanks to both of you for your input. My Client is deciding now whether to have a core 2 CPU or Pentium DC in new motherboard
