M321R2GA3BB6-CQK Samsung 2x8GB DDR5 RDIMM ECC RAM

High-Density DDR5 Registered Server Memory Expansion with the M321R2GA3BB6-CQK

M321R2GA3BB6-CQK is a Samsung DDR5 RDIMM kit engineered for enterprise servers that require registered memory to maintain signal integrity and predictable scaling on current CPU platforms. By deploying M321R2GA3BB6-CQK in compatible DDR5 RDIMM systems, IT teams can expand capacity without compromising stability, supporting balanced CPU-to-memory provisioning for virtualised and general-purpose compute environments.

The M321R2GA3BB6-CQK kit delivers 16GB total capacity via 2 x 8GB low-profile 288-pin RDIMMs at 4800 MT/s (JEDEC PC5-38400R) with CL40 timing and 1.1V operating voltage. In modern server architectures where PCIe 4.0/5.0 expansion and NVMe storage increase parallelism, memory bandwidth and deterministic latency become critical to keeping cores fed and reducing I/O wait. Single-rank x8 organisation supports efficient channel utilisation, while on-die ECC contributes to data integrity under sustained load, aligning with database buffering and consolidation targets.

Why Choose the M321R2GA3BB6-CQK?

M321R2GA3BB6-CQK provides a pragmatic density-to-performance step for DDR5 RDIMM platforms, enabling controlled scale-out of memory footprints per node while preserving enterprise reliability characteristics. It is well-suited for standardised fleet deployments where consistent module behaviour, registered buffering, and predictable interoperability simplify qualification and lifecycle management.

Samsung designs server DRAM with a focus on validated electrical margins, controlled process quality, and long-term supply alignment with modern data centre standards. This approach supports stable operation across multi-DIMM per channel configurations and helps maintain platform compliance for mission-critical infrastructure.

Key Applications:

• Virtualisation and VM consolidation
• General-purpose compute servers
• Database caching and buffering
• Enterprise application middleware
