System memory guidelines
The system supports DDR4 registered DIMM (RDIMMs) slots and load reduced DIMM (LRDIMMs) slots. System memory holds
the instructions that are executed by the processor.
Your system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into six channels. Six 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.
