Why won't CPU work with my mobo??

[mmasbou]

I have an Abit Fatal1ty AA8XE mobo which is right now running a Socket T LGA 775 Pentium 4 Prescott.
I want to upgrade my processor to a new Pentium D (also Socket T LGA 775). However, Newegg says that my mobo will only work with "Intel Pentium 4 EE HT/Pentium 4 Prescott/Celeron D." On an Intel site they recommended the Abit AW8-Max for a mobo to use with a Pentium D, which Newegg says can run with "Intel Pentium EE/Pentium 4 HT/Pentium D."

So my question is whether or not a new Pentium D will work with my Fatal1ty mobo??
If not, why not?

Thanks in advance.

The ABIT Fatal1ty-AA8XE is based on the Intel 925XE Alderwood chipset.

A Pentium D will require a minimal of Intel 945/955 chipset, see below:

Intel® Pentium D 8xx series Processor Support List.

I suspect newegg.com made a typo.

It's the same LGA775 socket, but the 925XE chipset doesn't have support for multiple cores. So sadly, no Smithfield or Conroe for us 🙁. That is (was) a nice mobo you have too.

If it's a BIOS issue, you can get a BIOS chip from Abit for $6 US.

Now, why in the world are you getting an Intel again? OMG, the Intel dual cores communicate through the Northbridge chipset according to some people here. Ouch.
