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
