Installation of DRAM modules (SIMM or DIMM)
3.2.1 SIMM (Single Inline Memory Module)
You can configure the system memory size in a variety of ways by using different
combinations of the four 72-pin DRAM SIMM. The memory must be 70ns (nanoseconds) or
faster using either Fast Page Mode or Extended Data Output (EDO) types. The memory
table below shows the different memory size combinations available. Please pay attention to
the following restrictions :
1) You must use one pair of sockets at a time in sequence ( i.e. SIMM1 and SIMM2, or all
four sockets at once).
2) Each pair of modules must be the same size and speed and may be single sided or
double-side
. Module sizes: Single-side SIMMs: 4MB, 8MB, 16MB; Double-side
SIMMs: 8MB, 32MB, 64MB
