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 3200MT/s, 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
● DIMM type (DIMM, 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.

Memory channels are organized as follows:

Processor Channel 0
Processor 1 Slots A1 and A7
Processor 2 Slots B1 and B7

General memory module installation guidelines

To ensure optimal performance of your system, follow the general guidelines when configuring your system memory. If your
system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during memory
configuration, or operate with reduced memory.
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:
● DIMM, RDIMMs, and LRDIMMs must not be mixed.
