System memory
System memory guidelines
The PowerEdge system supports DDR4 registered DIMMs (RDIMMs) and Load Reduced DIMMs (LRDIMMs). System memory
holds the instructions that are executed by the processor.
Your system contains 16 memory sockets that are 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:
