Figure 34. DIMM banks
v Each pair or bank of DIMMs must be of the same size and clock speed.
v When you install or remove a bank of DIMMs, the server configuration
information changes. Therefore, you must change and save the new
configuration information by using the Configuration/Setup Utility program. When
you restart the server, the server displays a message indicating that the memory
configuration has changed. Start the Configuration/Setup Utility program and
select Save Settings. If you need instructions, see "Chapter 2. Configuring the
server" in the User's Guide on the IBM Documentation CD.
v The illustrations in this document might differ slightly from your hardware.
