3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
To remove a dual inline memory module (DIMM), complete the following steps:
Step 1. Remove the cover (see “Removing the compute node cover” on page 113).
Step 2. Remove the air baffle (see “Removing the air baffle” on page 116).
Step 3. Remove the ServeRAID SAS/SATA controller first if you remove DIMM 13, DIMM 14, DIMM 15, or
DIMM 16.
Step 4. Carefully open the retaining clips on each end of the DIMM connector and remove the DIMM.
Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and
close the clips gently.

Step 5. If you are instructed to return the DIMM, follow all packaging instructions, and use any packaging
materials for shipping that are supplied to you.
Installing a memory module
The following notes describe the types of DIMMs that the compute node supports and other information
that you must consider when you install DIMMs.
• When you install or remove DIMMs, the compute node configuration information changes. When you
restart the compute node, the system displays a message that indicates that the memory configuration
has changed.
• The compute node supports only industry-standard double-data-rate 4 (DDR4), 1600, 1866, 2133, or 2400
MHz, PC4-12800, PC4-14900, PC4-17000, or PC4-19200 registered or load deduction, synchronous
dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting
code (ECC). See http://www.lenovo.com/ serverproven/ for a list of supported memory modules for the
compute node.
– The specifications of a DDR4 DIMM are on a label on the DIMM, in the following format. gggggeRxff
