Memory module installation rules
Your server has 16 memory slots. The following list describes the memory module installation rules.
• Each slot supports 4 GB, 8 GB, 16 GB and 32 GB double data rate 4 registered dual inline memory
modules (DDR4 RDIMMs) with Error Checking and Correcting (ECC) technology.
• Each slot supports 32 GB and 64 GB double data rate 4 load reduction dual inline memory modules
(DDR4 LRDIMMs) with ECC technology.
• Your server supports up to eight memory modules when one microprocessor is installed, or up to 16
memory modules when two microprocessors are installed.
• The minimum system memory is 4 GB (only one microprocessor installed and only one 4 GB RDIMM
installed in the CPU1 DIMMA1 slot).
• The maximum system memory is 1024 GB (two microprocessors installed and one 64 GB LRDIMM
installed in each of the 16 memory slots).
For more information about the memory modules in your specific server model, use the Setup Utility
