SIMM Upgrade
SIMM sticks are installed into SIMM sockets on the system board. The system board
provides four SIMM sockets and supports up to 128 MB of high-speed memory. The
system supports the following 32-bit (non-parity) SIMMs:
n
1-MB by 32-bit (4-MB stick)
n
2-MB by 32-bit (8-MB stick)
n
4-MB by 32-bit (16-MB stick)
n
8-MB by 32-bit (32-MB stick).
36-bit SIMMs may be used, but parity generation and checking is not supported.
To determine the memory needed for the memory upgrade, see Table 3-1. See "SIMM
Installation" in this section when installing the SIMMs.
NOTE: SIMM sockets must contain the same
size SIMMs and operate at 60 nanoseconds (ns)
in Fast Page Mode.
The factory installed SIMMs are installed in bank
1 (bank 0 is empty).
CAUTION: To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
