Option Installation 3-11
SIMM Upgrade
SIMM sticks are installed into SIMM sockets on the system board. The system board
provides four SIMM sockets and supports up to 256 MB of high-speed memory using
industry-standard, tin-plated, single in-line memory modules (SIMMs). The system supports
the following SIMMs:
1-MB by 32- or 36-bit (4-MB stick)
2-MB by 32-or 36-bit (8-MB stick)
4-MB by 32- or 36-bit (16-MB stick)
8-MB by 32-or 36-bit (32-MB stick)
16-MB by 32- or 36-bit (64-MB stick).
36-bit SIMMs may be used, but parity generation and checking is not supported.
NOTE:
The system ships with EDO SIMMs.
SIMM sockets must contain the same size
SIMMs.
SIMM memory must be installed in pairs of the
same memory type.
The factory-installed SIMMs are installed in
bank 1 (sockets 3 and 4). Bank 0 (sockets 1 and
2) is empty.
CAUTION:
To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
To determine the memory needed for the memory upgrade, see Table 3-1. See “SIMM
Installation” in this section when installing the SIMMs.
Checking the Memory in the System
Use the following procedure to:
check the memory installed in the system
determine the SIMM configuration you need to increase the memory
identify the correct sockets for SIMM installation.
