product details

Samsung M321R8GA0PB0-CWMCJ 64GB DDR5-5600 ECC RDIMM

The Samsung M321R8GA0PB0-CWMCJ is listed as a 64GB DDR5-5600 ECC RDIMM for enterprise server memory expansion. This class of registered memory is intended for platforms designed to support DDR5 ECC RDIMMs, where processor generation, BIOS level, population order, rank organization, and matched-DIMM policy can affect the achieved operating speed. It is a suitable component to evaluate for AI servers, virtualization hosts, database systems, and other memory-intensive deployments when the server’s qualified-memory list is considered.

Listed memory configuration

  • Manufacturer: Samsung
  • Part number: M321R8GA0PB0-CWMCJ

  • Memory type: DDR5 ECC RDIMM
  • Listed data rate: 5600 MT/s / PC5-44800
  • Module organization: 2Rx4

Server-memory validation

Before ordering, confirm that the server platform supports DDR5 RDIMM rather than UDIMM or LRDIMM, and verify the CPU generation and BIOS revision. Check the number of populated channels, existing DIMM part numbers, speed derating rules, and required capacity per socket. Mixing memory technologies, speeds, or module organizations can reduce performance or prevent a system from completing memory training.

Quotation support

Send the server make and model, processor configuration, current memory layout, total target capacity, and quantity. Topstar can help review whether the requested 64GB DDR5 ECC RDIMM configuration fits the platform’s memory population rules before purchase.
