IF you mean can you take the P4 out and use it in a different motherboard that supports DDR the answer is yes. I take it the CPU is a socket 478 ? If so there are so many motherboards out there it isnt funny ! I would go for a Intel 865 based motherboard unless you really want to send some $$ for a 875.
DDR2 is out but its mainly on LLGA775 based intel boards but man IT ROCKS ! Benchmarks of it and my new system are in the image gallery in the benchmarks section (Link at top of forums)
