Installing A Memory Module - IBM iDataPlex dx320 6385 User Manual

Installing a memory module

When you install memory, you must install a pair of matched DIMMs. Each DIMM in
a pair must be the same size, speed, type, and technology to ensure that the server
will operate correctly. Make sure that the replacement DIMM is the correct type of
memory (see the Problem Determination and Service Guide for a list of memory
that is compatible with the server).
Note: The default memory operating speed is 533 MHz for Web 2.0 power saving
optimization. Memory operating speed can be adjusted using the Chipset option in
the BIOS Setup Utility program.
When you install DIMMs, you must install the DIMMs in the order shown in the
following tables, to maintain performance.
