Memory module installation rules
Memory modules must be installed in a specific sequence based on the memory configuration that you
implement on your server. Understanding the technical rules for DIMMs helps you install the correct DIMMs
in the correct sequence.
Your server has 8 channels, 32 memory slots, and supports:
• Minimum capacity:
– 16 GB using RDIMMs
– 128 GB using 3DS RDIMMs
• Maximum capacity:
– 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
For a list of supported memory options, see: https://static.lenovo.com/us/en/serverproven/index.shtml
Note:
The operating speed and total memory capacity depend on the processor model and UEFI settings.
The following figure and table help you locate the memory slots and channels on the system board.
