Installing Memory-Module Kits
Adding memory to your server is an easy way to make programs
run faster. You can increase the amount of memory in your server
by installing options called memory-module kits. Your server uses
72-pin, parity, single-inline memory modules (SIMMs).
You install memory-module kits into connectors on a memory board
inside your server. The memory board contains two banks (1 and 2),
arranged in 16 SIMM sockets. To add memory to your server, you
can install additional memory-module kits on this memory board.
You can install a maximum of 2 GB of memory in your server, with
128 MB memory modules in all 16 sockets (connectors J1
through J16).
Each bank contains connectors for eight memory modules. As a
minimum, your server requires 16 MB memory modules in
connectors J1, J2, J3, and J4 in bank 1. To ensure proper server
operation, you must maintain 4, 8, or 16 memory modules in your
server. The memory-module kit sizes available for your server are
16 MB, 32 MB, 64 MB, and 128 MB. When you install 16 MB
memory modules in a bank, all of the memory modules in that bank
must be the same size. However, you can install 32 MB memory
modules in the other bank. If you install 64 MB or 128 MB memory
modules in one bank, and you want to install memory modules in
the other bank, those memory modules must also be 64 MB or 128
MB memory modules. The correct speed for these kits is 60 ns.
If additional memory is required, fill bank 1 first; then, continue
with bank 2. Bank 1 must be fully populated before you can install
memory modules in bank 2. If you need to install kits of a different
size in bank 1, remove the preinstalled kits as described in
“Removing Memory-Module Kits” on page 124, and install the
other kits as described in this section.
Table 2 on page 114 shows the memory configurations available for
your server. If you plan to install two different sizes of
memory-module kits on the memory board, use Table 2 as a guide.
