2.7 Configuring the System Memory
The system memory is expandable to 512 MB by adding single in-line
memory modules (SIMMs). The four 72-pin SIMM sockets accommodate
4-, 16- and 64-MB single-density SIMMs, and 8- and 32-MB double-density
SIMMs. These SIMM sockets also accept both Fast Page type and Extended
Data Output (EDO) type DRAMs. The EDO feature extends the data transfer
cycle, thus improves memory performance. All SIMMs support a DRAM
speed of 60/70 ns or less.
The following are the possible SIMM configurations. Notice that you must
install the same SIMMs in one bank.
