Samsung - DDR5 - modulo - 64 GB - DIMM 288-PIN - 5600 MHz / CL46 4Gx4 ECC reg. DR

For server and workstation builds that demand uncompromising memory integrity, the Samsung M321R8GA0EB0-CWM stands apart with its registered ECC architecture and 4Gx4 DRAM organisation. Unlike standard unbuffered modules, this RDIMM buffers command and address signals, enabling higher density configurations and rock-solid stability under continuous load. With 64 GB on a single 288-pin DIMM, it doubles the capacity of typical 32 GB modules while running at a brisk 5600 MT/s, making it a prime choice for virtualisation, in-memory databases, and compute-heavy applications.

Highlights

• 64 GB DDR5 registered ECC memory for servers and workstations
• 5600 MHz speed with PC5-44800 bandwidth and CL46 latency
• Dual-rank design with 4Gx4 chip organisation for optimal signal integrity
• On-die ECC and standard ECC for end-to-end data protection
• Low 1.1 V operating voltage for improved energy efficiency
• 288-pin DIMM form factor, compliant with JEDEC standards

In daily use

Deploying the M321R8GA0EB0-CWM means fewer interruptions and more consistent performance in memory-hungry environments. The registered buffer reduces electrical loading on the memory controller, allowing fully populated servers to run without the instability that can plague unbuffered modules. ECC corrects single-bit errors and detects multi-bit faults, while on-die ECC inside the DDR5 chips adds another layer of resilience. Whether you are consolidating VMs, crunching large datasets, or running mission-critical services, this module delivers the headroom and reliability your workloads expect.
