System memory
The system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the instructions
that are executed by the processor.
NOTE:
MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
•
DIMM type (RDIMM or LRDIMM)
•
Number of DIMMs populated per channel
•
System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
•
Maximum supported DIMM frequency of the processors
Your system contains 16 memory sockets split into two sets of 8 sockets, one set per processor. Each 8-socket set is organized into
channels. In each channel, the release tabs of the first socket are marked white, the second socket black.

General memory module installation guidelines
NOTE:
Memory configurations that fail to observe these guidelines can prevent your appliance from booting, stop responding
during memory configuration, or operating with reduced memory.
The following are the recommended guidelines for installing memory modules:
•
RDIMMs and LRDIMMs must not be mixed.
