Ok, so my computer is running 256mb of RDRAM and while I've been looking at prices for upgrading the ram the RDRAM is far more expensive from what I've found. So if I take out the RAM thats already in the computer and say put DDR ram in, is this possible. Screen shots are avalibile from that CPU-Z thing if nessercery. My computer is the Dell Dimension 8250. Thanks for any help .
