I would suggest an after-market brand. click here
for a 256MB Kingston brand. (2x256=512. Thats what you're looking for, right?)
I would think that you already know that you must install 2 modules for RDRAM to work so you'll have to buy two. ($170 total) Still a lot better than Dell's price..
As for ECC and non-ECC. You can mix the two.
the difference between 40ns and 45 ns is speed. Lower numbers = faster. If you're doing some serious sh!t on your computer you might notice, but for the average user, either one will do.
