Install a DIMM
Use this information to install a DIMM.
Before you install a DIMM, complete the following steps:
1. Read “Safety” on page iii and “Installation Guidelines” on page 21 to ensure that you work safely.
The compute node has a total of 24 dual inline DIMM connectors. The compute node supports low-profile
(LP) DDR4 DIMMs with error-correcting code (ECC) in 4 GB, 8 GB, 16 GB, 32 GB, and 64 GB capacity.
The following illustration shows the system-board components, including DIMM connectors.

Attention: Memory modules are sensitive to static discharge and require special handling. In addition to the
standard guidelines for Handling static-sensitive devices:
• Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-
discharge gloves can also be used.
• Never hold two or more memory modules together so that they touch. Do not stack memory modules
directly on top of each other during storage.
• Never touch the gold memory module connector contacts or allow these contacts to touch the outside of
the memory-module connector housing.
