Memory module installation rules and order
Memory modules must be installed in a specific order based on the memory configuration that you
implement on your server.
Your server has 16 channels, 32 memory slots, and supports:
• Minimum memory:
– 16 GB
• Maximum memory:
– 2 TB using RDIMMs
– 4 TB using 3DS RDIMMs
• Type (depending on the model):
– TruDDR4 3200, dual-rank, 16 GB/32 GB/64 GB RDIMM
– TruDDR4 3200, quad-rank, 128 GB 3DS RDIMM
– TruDDR4 3200 128 GB/256 GB PMEM
