It needs to be same pin count, supported speed (PC3200 i suppose since you are looking at those), it most likely needs to be NON-ECC registered/Unbuffered (unless you are running a server machine specially made for that kind of RAM). DELL should work with most Corsair modules...however it's not guaranteed. Older DELL motherboards are extremely picky with what brand of RAM they take. It will most likely work though...
