Installing a memory module
Use these instructions to install memory modules in the blade server.
The following notes describe the types of direct inline memory modules (DIMMs)
that the blade server supports and other information that you must consider when
you install DIMMs:
Note:
1.
The following illustration shows the location of the DIMM connectors on the
system board.
2.
The illustrations in this document might differ slightly from your hardware.
v
The system board has DIMM connectors.
v
The server supports two-way memory interleaving.
v
The optional DIMMs that are available for the blade server are 512 MB, 1 GB, 2
GB, and 4 GB. Depending on the memory configuration that is set in the
Configuration/Setup Utility program, the blade server can support a minimum
of 1 GB and a maximum of 24 GB of system memory on the system board.
v
When you install memory, you must install a pair of matched DIMMs. Some
blade server models come with one DIMM installed in DIMM slot 1. In this case,
you must order and install a second matched DIMM in DIMM slot 2. Install the
DIMMs in the order shown in the following table.

All DIMMs in a pair or group must be the same size, speed, type, technology,
and physical design. You can use compatible DIMMs from different
manufacturers.
v
Install only ECC DDR2 667 DRAM with ECC DIMMs. For a current list of
supported DIMMs for the blade server, see http://www.ibm.com/servers/
