Memory modules must be installed in a specific order based on the memory configuration that you implement on your server.
Your server has 24 memory module slots. It supports up to 12 memory modules when one processor is installed, and up to 24 memory modules when two processors are installed. Supporting memory module type is as follows:
Type: TruDDR4 2666, dual-rank, 16 GB/32 GB RDIMM
For Intel Xeon Cascade Lake processors:
TruDDR4 2933, dual-rank, 16 GB/32 GB RDIMM
