>it has to be ECC and Registered right?
There is a memory list/faq with tested modules on morphzone. Personally, I just bought a no-name 256MB module from the next dealer, and it works perfectly. Ironically, the registered module that came with the board failed to work. If you have a tolerant local dealer (with a good return policy), and they still have SD-RAM, why not give it a try?
