Installing A Memory Module - IBM BladeCenter HS22V Installation And User Manual

Installing a memory module

Use these instructions to install memory modules in the blade server.
The blade server has a total of eighteen direct inline memory module (DIMM)
slots. The blade server supports very low profile (VLP) DDR3 DIMMs with error
code correction (ECC). For a current list of supported DIMMs for the blade server,
see http://www.ibm.com/servers/eserver/serverproven/compat/us/.
After you install or remove a DIMM, you must change and save the new
configuration information by using the Setup utility. When you turn on the blade
server, a message indicates that the memory configuration has changed. Start the
Setup utility and select Save Settings (see "Setup utility menu" on page 56 for
more information) to save changes.
Depending on the memory mode that is set in the Setup utility, the blade server
can support a minimum of 1 GB and a maximum of 144 GB of system memory on
the system board in a blade server with one processor. If two microprocessors are
installed, the blade server can support a minimum of 2 GB and a maximum of 288
GB of system memory. There are three different memory modes:
v Independent channel mode: Independent channel mode gives a maximum of
