M321R4GA0BB0-CQK Samsung 1x32GB DDR5 RDIMM RAM

Enterprise DDR5 RDIMM Memory Upgrade Optimised for ECC Reliability with the M321R4GA0BB0-CQK

The M321R4GA0BB0-CQK is a Samsung 32GB DDR5-4800 registered ECC RDIMM designed for current Intel Xeon Scalable and AMD EPYC server platforms where predictable latency, signal integrity, and multi-channel scaling are mandatory. Deployed across dual-socket architectures, the module supports balanced channel population to sustain throughput for virtualization stacks, database engines, and general compute services.

With DDR5’s improved bank structure and on-die ECC, the M321R4GA0BB0-CQK enhances resilience at higher data rates while RDIMM buffering stabilizes memory signalling as DIMM counts increase. The 288-pin, low-profile form factor fits dense rack servers, and the 1.1V operating point helps control platform power at scale. For PCIe Gen4/Gen5 I/O-heavy configurations, adequate memory bandwidth and capacity headroom reduce bottlenecks when storage and accelerator traffic increases under consolidated workloads.

Why Choose the M321R4GA0BB0-CQK?

The M321R4GA0BB0-CQK targets the practical requirement of capacity expansion without compromising enterprise reliability, enabling consistent performance per node while maintaining serviceability in standard RDIMM slots. It provides an efficient density-to-performance step for environments scaling out VM counts or expanding in-memory working sets, and it aligns with validated server memory topologies for predictable deployment across fleets.

Samsung designs server DRAM for continuous duty cycles, emphasizing qualification discipline, tight process control, and compatibility with modern data centre standards. The M321R4GA0BB0-CQK reflects this approach through registered ECC operation, DDR5 power efficiency, and RoHS-compliant manufacturing suitable for long lifecycle infrastructure planning.

Key Applications:

• Virtualization and private cloud hosts
• Database servers and caching tiers
• Enterprise application servers
• VDI density expansion
