If the presently installed processors do not support DCPMMs, replace them with the processors that
support DCPMMs.
• DCPMMs are supported only by Intel Xeon SP Gen 2. For a list of supported processors and memory
modules, see
http://www.lenovo.com/us/en/serverproven/
• When you install two or more DCPMMs, all DCPMMs must have the same Lenovo part number.
• All DRAM memory modules installed must have the same Lenovo part number.
• 16 GB RDIMM has two different types: 16 GB 1Rx4 and 16 GB 2Rx8. The part number of the two types
are different.
• Supported memory capacity range varies with the following types of DCPMMs.
– Large memory tier (L): The processors with L after the four digits (for example: Intel Xeon 5215 L )
– Medium memory tier (M): The processors with M after the four digits (for example: Intel Xeon Platinum
8280 M )
– Other: Other processors that support DCPMMs (for example: Intel Xeon Gold 5222 )
• In addition, you can take advantage of a memory configurator, which is available at the following
site:

.
The following illustration helps you to locate the memory module slots on the system board.

App Direct Mode
Memory modules must be installed in a specific order based on the memory configuration that you
implement on your system. Follow the information of App Direct Mode as below.
Table 18. Four categories of DIMM
DIMM Category DDR4 Type Capacity
D1 RDIMM 3DS RDIMM Any density of DDR4 except 8 GB 1Rx8 RDIMM
D2 RDIMM
3DS RDIMM All density of DDR4 more than 32 GB
D3 RDIMM 16 GB or 32 GB RDIMM
D4 RDIMM 3DS RDIMM Any density of DDR4 except 8 GB 1Rx8 RDIMM
Following are all the combinations that are supported in this solution.
App Direct Mode with one processor
Note: When adding one or more DCPMMs and DIMMs during a memory upgrade, you might need to move
other DIMMs that are already installed to new locations.
