Installing memory modules
The server supports up to four pairs of DIMMs and supports memory interleaving.
Adding memory to the server is an easy way to make programs run faster.
Notes:
1. The server supports a minimum of 512 MB of system memory and a maximum of
8 GB of system memory. The DIMM slots are arranged in two columns of four
rows each. The server supports DIMMs of 256 MB, 512 MB, and 1 GB capacities.
2. Each pair of DIMMs must be the same type, capacity, and speed. However, you
can install DIMM pairs of different capacities as long as both DIMMs in each pair
are the same.
3. Installing or removing DIMMs changes the configuration information in the server.
Therefore, after installing or removing DIMMs, you must save the new
configuration information using the Configuration/Setup Utility program. When
you restart the server, the system displays a message indicating that the memory
configuration has changed. Start the Configuration/Setup Utility program and
select
Save Settings. See Chapter 3, “Configuring the server,” on page 13 for
more information.
Complete the following steps to install the DIMMs:
1. Review the safety precautions beginning on page 53, “Handling static-sensitive
devices” on page 52, and the documentation that comes with the DIMMs.
2. Turn off the server, disconnect all power cords and external cables, and remove
the top cover (see “Removing the server top cover and bezel” on page 66).
Note: If the server had a DIMM failure, a DIMM LED on the memory board
indicates the failing module.
