Designed exclusively for server platforms, this DDR5-4800 Registered DIMM with ECC delivers maximum data integrity and stability for mission-critical workloads such as virtualization, in-memory databases, and dense cloud computing. Its single-rank x8 configuration at CL40 reduces electrical loading on the memory bus, enabling higher population density per channel while ensuring reliable, low-latency operation under sustained enterprise loads.
1. DDR5 memory technology doubles the bank count and advances power efficiency, sustaining massive parallel workloads such as real-time analytics and high-frequency trading with stable throughput.
2. 16GB capacity per module hits a sweet spot for dense server configurations, letting a single rack unit pack ample memory headroom for virtualized environments and container fleets without sacrificing cost per gigabyte.
3. ECC error correcting silently scrubs single-bit faults before they become service-crippling events, safeguarding transactional databases and long-running scientific computations against silent data corruption.
4. Registered RDIMM buffering strengthens command/address signal integrity, making it feasible to populate all channels fully in a 24-DIMM server while maintaining unwavering uptime under constant load.
5. 4800MT/s data rate supplies the memory bandwidth required to feed multi-core server CPUs efficiently, eliminating bottlenecks that would starve NVMe all-flash arrays and AI accelerators of data.
The Samsung M321R2GA3BB6-CQKVS is a server-class DDR5 Registered DIMM engineered for modern data centers where data integrity and uninterrupted uptime are non-negotiable. In a dense virtualization cluster, its DDR5-4800 bandwidth shatters the throughput ceiling of previous generations, ensuring dozens of VMs can concurrently access memory-critical services without I/O stalls. This directly translates into faster response times for business applications and containerized microservices. When running an in-memory database like Redis or SAP HANA, the integrated ECC engine is your frontline defense against silent bit-flips caused by cosmic radiation or electrical noise—a single undetected error could corrupt financial transactions or patient records, but ECC corrects these faults automatically, preserving absolute data accuracy around the clock. The Registered signal buffering tackles the scalability pain point: it stabilizes command and address lines when populating all memory channels, enabling reliable 2TB+ configurations without signal degradation, which is vital for memory-hungry virtualized environments. Finally, the 1.1V operating voltage significantly slashes power consumption per server node, reducing both cooling overhead and operational expenditure at scale. For any enterprise IT architect, this RDIMM converts raw specifications into tangible resilience, density, and cost efficiency.
General Virtualization
This 16GB DDR5-4800 RDIMM provides a reliable foundation for moderate-density hypervisor hosts. Deploy six to eight modules per server (96–128 GB) in balanced channels to support 20–30 typical VMs without excessive memory overcommit. The ECC and registered design ensure data integrity and stability under multi-tenant workloads.
In-Memory Database
For in-memory databases like Redis or SAP HANA, low latency and data protection are critical. Populate all memory channels symmetrically with at least eight modules (128 GB) or scale to sixteen (256 GB) for larger datasets. Single-rank x8 configuration helps maintain high clock speeds, and ECC guards against silent data corruption during real-time analytics.
High-Performance Computing
HPC clusters benefit from consistent per-core memory bandwidth. Install one module per channel across all available slots—typically 8 or 16 DIMMs per node—to maximize parallel throughput. The DDR5-4800 speed and registered signaling reduce electrical load on the memory bus, letting compute-bound simulations and modeling jobs run stable at full socket capacity.

Q: Can I mix this M321R2GA3BB6-CQKVS with other memory modules of different brands or speeds?
A: Not recommended. Mixing registered DIMMs with different specifications or brands can cause signal integrity issues and system instability. For reliable operation, use identical modules with the same Samsung part number across all channels.
Q: Is this memory compatible with my system?
A: This DDR5 RDIMM is validated for server platforms supporting registered ECC memory, including Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series. Always verify CPU and motherboard support for DDR5-4800 RDIMMs before purchase.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server board’s manual for balanced memory configurations. Typically, populate one DIMM per channel first, starting from the farthest slot from the CPU. Symmetric population across memory controllers maximizes bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise-grade registered ECC module, it operates strictly at JEDEC-standard DDR5-4800 timings. It does not support XMP or user overclocking—reliability and data integrity take priority over tunable frequency.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Server-class RDIMMs undergo rigorous screening and exhibit very low annualized failure rates, typically far below 0.1%, ensuring dependable long-term operation in data center environments.
