Adding Memory
Memory can be increased to a maximum of 256 megabytes (MB) by installing combinations of 16-, 32-, 64-, or 128-MB nonparity
synchronous dynamic random-access memory (SDRAM) dual in-line memory modules (DIMMs) in the two DIMM sockets on the
system board. Figure 6-6 shows the DIMMs and DIMM sockets. DIMM speed (66 megahertz [MHz]) should match the external bus
speed of the microprocessor.
Figure 6-6. DIMMs and DIMM Sockets
Table 6-1 lists sample memory configurations and shows valid DIMM combinations and socket placements for each configuration.
