Technical Information 1-9
The SIMM memory sockets accept 32-bit (non-parity) 4-, 8-, 16-, or 32-MB 70 ns SIMMs.
The SIMMs are 1 MB x 32 bit (4 MB), 2 MB x 32 bit (8 MB), 4 MB x 32 bit (16 MB), and
8 MB x 32 bit (32 MB). When the standard SIMMs are removed, four 32-MB SIMMs may
be installed for a total of 128 MB.
CAUTION:
SIMMs must match the tin metal
plating used on the system board SIMM sockets.
When adding SIMMs, use tin-plated SIMMs.
SIMMs install directly in the four sockets on the system board. The four sockets are
assigned as SIMM 1 through SIMM 4. For non-multimedia configurations, the two
standard 4 MB SIMMs are installed in SIMM 1 and SIMM 2. For multimedia
configurations, the two standard 8 MB SIMMs are installed in SIMM 1 and SIMM 2.
SIMMs must be installed in pairs of the same memory type and speed. Jumpers are not
required to set memory size or type as the system BIOS automatically detects the SIMMs.
SIMM banks 1 and 2 must always be filled for the system to operate. Table Section 1-5
shows the SIMM memory upgrade path.
