Can anyone tell me which motherbard will work and CPU so I can upgrade this dell xps 400 to run vista Ultimate 64 bit? I was told that I needed a 64 bit CPU and would have to change the Motherboard also is that true? I have a new Video card waiting and 2 sticks of new ram to bring the system up to 4gigs but am waiting to find out about the motherboard and CPU,
Here is what I have now,

Dell DXP051
Board: Dell Inc. 0FJ030
Bus Clock: 800 megahertz
BIOS: Dell Inc. A07 01/08/2007

Processor
2.80 gigahertz Intel Pentium D
16 kilobyte primary memory cache
1024 kilobyte secondary memory cache

3072 Megabytes Installed Memory

Slot 'DIMM_1' has 1024 MB
Slot 'DIMM_3' has 512 MB
Slot 'DIMM_2' has 1024 MB
Slot 'DIMM_4' has 512 MB

maybe a link to the part/parts I would need, or info on where to buy,
thanks guys!

Despite what you've been told, your Pentium D is an x64 processor so you do not need to replace it just to run Vista x64. It is not the fastest CPU out there, but it will work.

I was goning to purchase the vista ultimate 64bit (OEM) but thought I wasn't able to run it
I will have to do a complete format from 32bit XP Pro to be able to install the 64 bit OS im told also,
Thanks again for help!!

I tried to upgrade the mother board in my XPS400, to a later DELL model,
but it would not fit (I couldn't find any 3d party mfg. that would fit in a DELL?).

My Upgrades that REALLY worked!-
1. I upgraded to 4 gig (2gig x 2 is best!) of "matching" Crucial memory (Dual channel!). Helped some.

2. I then upgraded my C: hard drive to a Western Digital Raptor 10k rpm Hard Drive!
WOW!- My computer is now BLAZING FAST!
