2. Supported DIMM capacity is up to 64 GB.
Memory Mode
Memory modules must be installed in a specific order based on the memory configuration that you
implement on your node. Below is the information of memory mode.
Note: Before installing DCPMM, refer to “Memory configuration” on page 202 and “Configure DC Persistent
Memory Module (DCPMM)” on page 202 for the requirements.
Table 20. Four categories of DIMM
DIMM Category
DDR4 Type
Capacity
D1 RDIMM
3DS RDIMM Any density of DDR4 except 8 GB 1Rx8 RDIMM
