System memory guidelines

The PowerEdge MX750c system supports DDR4 registered DIMMs (RDIMMs), load reduced DIMMs (LRDIMMs), Intel Optane
Data Center Persistent Memory Modules (DCPMMs). System memory holds the instructions that are executed by the
processor.
Your system contains 32 memory sockets that are split into two sets of 16 sockets, one set per processor. Each 16-socket set is
organized into eight channels. Eight memory channels are allocated to each processor. In each channel, the release tabs of the
first socket are marked white, and the second socket black.
Memory channels are organized as follows:
