Installing a memory module The following notes describe the types of dual inline memory modules (DIMMs) that your server supports and other information that you must consider when installing DIMMs: v Your server uses interleaved dual inline memory modules (DIMMs), which you must add, remove, or replace in pairs.

Installing a memory module
The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when installing
DIMMs:
v
Your server uses interleaved dual inline memory modules (DIMMs), which you
must add, remove, or replace in pairs. Each pair must be of the same type,
capacity, and speed. The server comes with one pair of DIMMs installed in DIMM
slots 1 and 2 on the system board.
v
You can increase the amount of memory in the server through one of the
following methods:
Replacing the installed DIMMs with higher-capacity DIMMs
Installing an additional pair of DIMMs in slots 3 and 4 for a single
microprocessor configuration
Installing an additional pair of DIMMs in slots 5 and 6 for a
dual-microprocessor configuration
Note:
For optimal dual-microprocessor performance, install DIMMs in slots 1,
2, 5, and 6.
v
The server supports 512 MB and 1 GB DIMMs. See the ServerProven
®
list at
http://www.ibm.com/pc/us/compat/ for a list of memory modules that are
supported by the server. The following illustration shows the memory slots on the
system board.
