Hi, I am looking at buying 1.8 socket 423 chip to replace my 1.3 chip in my 8100. The guy who is selleng me this chip also has a Dell socket 423 motherboard that uses DDR RAM and 256mb of PC2100 DDR ram that he will throw in for cheap. My question is can I put that motherboard in an older dell. I have two other dells that might be able to take this motherboard an XPS B800r and a XPS T450. Please let me know if I can put this motherboard in one of these computers. If not what models will this board fit in.

Thanks

Sean
