System memory
The sled supports DDR4 registered DIMMs (RDIMMs), load reduced DIMMs (LRDIMMs), Non-Volatile DIMMs (NVDIMM-Ns),
and Intel Optane Data Center Persistent Memory Modules (DCPMMs) . System memory holds the instructions that are
executed by the processor.
Memory channels and population
The system supports DDR4 registered DIMMs (RDIMMs), Load Reduced DIMMs (LRDIMMs), Non-Volatile DIMMs (NVDIMM-
Ns), and Intel Optane Data Center Persistent Memory Modules (DCPMMs) . System memory holds the instructions that are
executed by the processor.
● DIMM type (RDIMM or LRDIMM or NVDIMM-N or DCPMM)
● Number of DIMMs populated per channel
● System profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)
● Maximum supported DIMM frequency of the processors
