Memory Configuration
The system memory is expandable to 128 MB by adding single in-line
memory modules (SIMMs). The four 72-pin SIMM sockets accommodate 1-
, 4-, 16- and 64-MB single-density SIMMs, and 2-, 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 70/80 ns or less.
The table below lists the SIMM types and their corresponding capacity.
SIMM Type Capacity
256 Kb x 32/36 1 MB
512 Kb x 32/36 2 MB
1 Mb x 32/36 4 MB
2 Mb x 32/36 8 MB
4 Mb x 32/36 16 MB
8 Mb x 32/36 32 MB
16 Mb x 32/36 64 MB
The SIMM sockets support 32-/64-bit DRAMs, therefore allowing you to
install one SIMM in one bank instead of two. However, you can install this
DRAM type only on SIMMs 2 and 4.
