Installing Additional System Memory

Adding more memory allows your system to run larger, more memory-intensive software.
You can increase your system's memory to 512 MB (megabytes). You can add 32-MB,
64-MB, 128-MB, or 256MB memory options. Each memory option consists of four single
in-line memory modules (SIMMs):
•
32-MB option consisting of four 8-MB SIMMs
•
64-MB option consisting of four 16-MB SIMMs
•
128-MB option consisting of four 32-MB SIMMs
•
256-MB option consisting of four 64-MB SIMMs
SIMMs must be of the same capacity and must always be added in sets of four into one of
two available memory banks, bank 0 or bank 1 (see items 10 and 11 in Figure 4-3). If all
SIMM slots are already used, you can still increase your system's memory by removing
four SIMMs from one of the banks and replacing them with four larger SIMMs. The
system requires 72-pin parity SIMMs that have an access time of 60 ns or 70 ns.
