Lenovo Flex System x440 Compute Node Installation And Service Manual page 903

This component can be installed as an optional device or as a CRU. The installation procedure is the same
for the optional device and the CRU.
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 compute node, a message indicates that the memory configuration
has changed. Start the Setup utility and select Save Settings (see
more information) to save changes.
If you are installing a DIMM as a result of a DIMM failure, you might have to reenable the DIMM. To re-enable
the DIMM, complete the following steps:
1. Verify that the amount of installed memory is the expected amount of memory through the operating
system, by watching the monitor as the compute node starts, by using the CMM
through the management node (if available).

2. Run the Setup utility to reenable the DIMMs (see
information).
The compute node has a total of 48 dual inline memory module (DIMM) connectors. The compute node
supports low-profile (LP) DDR3 DIMMs with error-correcting code (ECC) in 4 GB, 8 GB, 16 GB and 32 GB
capacities.
