Adding Memory

Memory can be increased to a maximum of 768 megabytes (MB) by installing combinations of 32-, 64-, 128-,
or 256-MB dual in-line memory modules (DIMMs) in the three DIMM sockets on the system board.

Figure 6

shows the DIMMs and DIMM sockets.

Your system can support both error checking and correction (ECC) and nonparity synchronous dynamic
random-access memory (SDRAM) DIMMs. However, ECC support is available only if all DIMMs are ECC
DIMMs. ECC DIMMs enable your system to correct all single-bit memory errors and detect multibit memory
errors.

When you add system memory, you may install DIMMs in any socket. For optimum operation, Dell
recommends that you install a DIMM in socket A first (closest to the processor) before installing a DIMM in
another socket.
