System Board Installation
When installing memory modules in the system board sockets and not using
the optional memory riser boards, observe the following guidelines:
• Each memory socket on the system board must be occupied either by a
RIMM or a CRIMM.
• Memory sockets must be upgraded in matched pairs. In other words,
two sockets in a pair must contain modules of identical capacity,
number of components, and speed. See "System Board Memory
Components" to identify pairs of sockets.
