– Without PMEMs:
– 2 TB using RDIMMs
– With PMEMs in Memory Mode:
– 5 TB using RDIMMs and PMEMs
• Type (depending on the model):
– TruDDR4 3200, dual-rank, 16 GB/32 GB/64 GB RDIMM
– 128 GB/256 GB PMEM
For a list of supported memory options, see: https://static.lenovo.com/us/en/serverproven/index.shtml
