SAMSUNG M321R8GA0BB0-CQK 64GB DDR5-4800 ECC RDIMM server RAM

SKU CH-HY15-R3QZ6

64 GB DDR5-4800 ECC registered server memory for data-centre workloads

  • 64 GB capacity supports memory-intensive server workloads
  • DDR5-4800 speed delivers high bandwidth for data processing
  • ECC RDIMM design corrects errors to protect data integrity
  • Samsung components provide reliable performance in mission-critical environments
  • Rigorously stress-tested modules ensure stability under heavy loads

Server memory module for enterprise workloads

This Samsung DDR5-4800 ECC RDIMM delivers 64 GB of registered memory with on-die error correction. It is built for multi-socket servers, virtualisation hosts and high-density workstations that require data integrity under sustained load.

Suited for IT teams deploying qualified OEM

The module targets system integrators and administrators who validate memory against vendor compatibility lists. It is not appropriate for consumer desktop boards that lack RDIMM support or for laptops and small-form-factor systems limited to unbuffered SODIMMs.

DDR5-4800 registered ECC specification

The 4800 MT/s data rate and registered architecture define whether the memory matches the platform memory controller and firmware requirements. Confirm the server qualified-vendor list before purchase.

Questions about this item

Will this 64GB DDR5-4800 RDIMM fit a standard 288-pin DDR5 server DIMM slot?

Yes, the module uses the standard DDR5 RDIMM form factor with 288 pins, matching server motherboard slots designed for DDR5 registered memory.

What is the correct way to seat this ECC RDIMM so the register engages properly?

Align the module notch with the slot key, press down firmly and evenly on both ends until the retention clips click shut, ensuring the register makes full contact.

How do I know when this 64GB module should be replaced in a production server?

Replace the module if system logs report uncorrectable ECC errors, if memory diagnostics fail consistently, or if the server exhibits unexplained crashes under load.
