DIMM population information
For specific DIMM population information, see the DIMM population guidelines on the Hewlett Packard Enterprise website
(https://www.hpe.com/docs/amd-population-rules-Gen10Plus).
DIMM-processor compatibility
The installed processor determines the type of DIMM that is supported in the server:
AMD EPYC processors support DDR4-3200 DIMMS.
Mixing DIMM types is not supported. Install only the supported DDR4-3200 DIMMs in the server.
Memory speed tables
For specific DDR4 server memory speeds, for HPE servers using AMD processors, see the Hewlett Packard Enterprise
website (https://www.hpe.com/docs/amd-speed-table-Gen10Plus).
Installing a DIMM
Prerequisites
Before installing this option, be sure that you have the following:
The components included with the hardware option kit
Procedure
1.
Observe the following alerts:
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning any
installation procedure. Improper grounding can cause electrostatic discharge.
2.
Power down the server.
3.
Disconnect all peripheral cables from the server.
4.
Remove the system board module from the chassis.
5.
Place the system board module on a flat, level work surface.
6.
Remove the system board module access panel.
7.
Remove the air baffle.
8.
Install the DIMM:
a. Open the DIMM slot latches.
b. Align the notch on the bottom edge of the DIMM with the keyed surface of the DIMM slot, and then fully press
the DIMM into the slot until the latches snap back into place.
