Chapter 2 - CPU Board 2-5
2.3 Memory Upgrade
The system board comes with four 168-pin sockets, labeled DIMM1 to DIMM4,
that accommodate single-density and double-density, unbuffered or registered
SDRAM DIMMs.
The SDRAM DIMMs should work under 3.3 volts. 5 volts memory devices are
not supported. Memory timing setting of 66 MHz are defined under unbuffered
DIMM specifications while 100 MHz are defined under Intel PC-100 SDRAM and
PC registered DIMM specifications.
Do not use both 66 MHz (unbuffered) and
100 MHz (registered) SDRAM together. This
might cause your system to malfunction.
The sockets support SDRAM DIMMs for a total of 512 MB (unbuffered) system
memory using 128 MB DIMMs. Tables 2-3 and 2-4 list some possible memory
configurations.
