System Memory
You can increase system memory up to 512 MB by using synchronous dynamic random-access memory (SDRAM) dual in-line memory modules
(DIMMs). The
system board
illustration shows the location of the DIMM sockets on the system board (DIMMs must be non-error checking and
correction [non-ECC]).
When you add system memory, you may install DIMMs in either socket. For optimum operation, Dell recommends that you install a DIMM in socket
A first (closest to the processor) before installing a DIMM in socket B.
