System Board 1-171.8 Memory UpgradeThe four 168-pin sockets onboard support SDRAM-type DIMMs. Youmay install 32-MB, 64-MB, or 128-MB DIMMs for a maximum of512-MB system memory.The SDRAM DIMMs should work under 3.3 volts; 5 volt memorydevices are not supported. Memory module with a timing setting of66 MHz are defined under unbuffered DIMM specifications, while 100MHz modules are defined under Intel PC-100 SDRAM specificationsand PC registered DIMM specifications.Do not use both 66 MHz (unbuffered) and100 MHz (registered) SDRAM together. Thismight cause your system to malfunction.Each of the sockets represents one independent bank. This allowsyou to install DIMMs with different capacities to form a configuration.1.8.1 Memory ConfigurationsTable 1-3 lists some system memory configurations. You maycombine DIMMs with various capacities to form other combinations.Table 1-3 Memory ConfigurationsDIMM1 DIMM2 DIMM3 DIMM4 Total Memory32 MB 32 MB32 MB 32 MB 64 MB32 MB 32 MB 32 MB 96 MB32 MB 32 MB 32 MB 32 MB 128 MB64 MB 64 MB64 MB 64 MB 128 MB64 MB 64 MB 64 MB 192 MB
