This DDR5-4800 Registered DIMM with ECC is purpose-built for server platforms handling virtualization, in-memory databases, and mission-critical workloads where data integrity is paramount. Its single-rank x8 organization and registered signal architecture enable stable operation at 4800MT/s across densely populated memory channels, while ECC corrects single-bit errors to prevent silent data corruption in 24/7 enterprise environments.
1. Next-gen DDR5 doubles the bank groups over previous generations, dramatically boosting concurrent access capability for heavy virtualization and containerized workloads.
2. Error-correcting code support eliminates silent data corruption, ensuring uncompromised data integrity for financial ledgers and critical database transactions.
3. Registered buffer technology stabilizes command and address signals, allowing dense server boards to run reliably with all memory channels fully loaded.
4. The elevated interface frequency delivers substantially higher throughput per core, accelerating large-scale in-memory analytics and AI inference pipelines.
5. Single Rank x8 organization presents a lighter electrical load to the memory controller, preserving maximum achievable clock speeds in high-capacity multi-DIMM deployments.
Built for the relentless demands of modern data centers, the Samsung M321R2GA3BB6-CQKDG is a DDR5-4800 Registered DIMM engineered to eliminate the silent threats that cripple server performance. Its ECC technology is your first line of defense against bit-flipping errors caused by cosmic radiation or electrical noise — a single uncorrected error in a virtualization cluster can corrupt a live VM’s memory state and cause an entire node to fail, taking dozens of workloads offline. The Registered signal buffer means you can densely populate memory channels without signal degradation, a critical advantage when scaling an in-memory database like SAP HANA. Here, every transaction lives in RAM, and signal instability at high capacities directly translates into latency and abandoned queries. Running at a crisp 4800 MT/s on just 1.1V, this low-voltage, single-rank x8 module delivers extraordinary bandwidth while keeping thermals in check, allowing your hypervisor to smoothly juggle hundreds of containers or accelerating the real-time analytics that your business decisions depend on. This isn’t just faster memory — it’s insurance for data integrity and workload continuity where downtime is measured in lost revenue.
General Virtualization
Populate identical 16 GB RDIMMs evenly across all memory channels, ideally one DIMM per channel (1DPC) to sustain full DDR5-4800 speed. For an 8-channel server this yields 128 GB per socket, comfortably hosting 20–30 moderate virtual machines. The registered ECC design provides the data integrity and stability that multi-tenant hypervisor environments require.
In-Memory Database
Maximize capacity by fully populating every channel, using two DIMMs per channel if the workload demands more than 128 GB per socket, though speed may step down to 4400 MT/s. A dual-socket server with 32 modules delivers 512 GB of reliable, ECC-protected memory, ideal for real-time analytics and large in-memory datasets. Registered buffering also preserves signal quality under heavy load.
High-Performance Computing
Achieve peak memory bandwidth by installing one 16 GB RDIMM per channel; eight modules supply 128 GB per 8-channel CPU at DDR5-4800 without signal-loading penalties. This 1DPC layout keeps latency low and throughput high for simulation and modeling codes, while ECC ensures computational correctness over extended runs. Scale horizontally across identical nodes rather than overloading a single server.

Q: Can I mix this M321R2GA3BB6-CQKDG with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not advised. Mismatched attributes can cause instability, parity errors, or performance loss. Always use identical Samsung part numbers, speed, and rank for validated server operation.
Q: Is this memory compatible with my system?
A: This DDR5 ECC Registered DIMM targets 4th/5th Gen Intel Xeon Scalable and AMD EPYC 9004 platforms. Verify your server’s qualified vendor list (QVL) and ensure 288-pin DDR5 RDIMM support before purchase.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow motherboard-specific population rules, usually filling identical slots per channel first. A balanced population across all memory controllers maximizes bandwidth and interleaving, critical for server applications.
Q: Does this module support overclocking or XMP profiles?
A: No. This JEDEC-compliant DDR5-4800 RDIMM operates at fixed timings and voltage. It does not support XMP or overclocking, prioritizing data integrity and stability in enterprise environments.
Q: What warranty and typical failure rate can I expect?
A: It includes a one-year warranty. Samsung Enterprise RDIMMs exhibit an extremely low annualized failure rate (AFR), typically under 0.1%, reflecting robust design for continuous data center workloads.
