I have a 512 memory stick of Geil Ultra DDR pc4200 memory and need to go to 1G. Geil does not make this stick any more. I dont know if I will have to go to a lower speed sdram or if I can find comperable memory elswhere. Thanks for the help!
You can try a compatible brand of pc4200 from another maker and hope it works, or just sell that one and buy 1gb of another brand.
