This DDR5-4800 registered ECC memory module is engineered for server platforms, delivering exceptional reliability for virtualization, in-memory databases, and mission-critical enterprise workloads that demand uncompromising data integrity. Its dual-rank x8 architecture and registered signal type enhance signal stability and memory bandwidth in multi-DIMM configurations, while hardware ECC actively corrects single-bit errors to prevent silent data corruption.
1. ECC protection corrects single-bit memory errors in real time, preventing silent data corruption that could crash financial transactions or corrupt critical database records.
2. Registered signal buffering stabilizes command and address lines at high capacity, allowing data centers to fully populate 24-DIMM boards for seamless large-scale virtualization.
3. 32GB capacity per module elevates memory density, maximizing the number of virtual machines per physical host without sacrificing performance under heavy consolidation.
4. Dual Rank x8 organization interleaves accesses across internal banks, boosting sustained bandwidth that keeps multi-core server CPUs fed during concurrent analytics jobs.
5. DDR5 technology doubles the burst length and raises effective throughput, shrinking processing time for in-memory AI inference and real-time big data workloads.
The M321R4GA3BB0-CQKDG is a 32GB DDR5-4800 RDIMM engineered for enterprise servers where uncompromising reliability and performance are non-negotiable. Its ECC technology silently corrects single-bit errors in real time, directly preventing data corruption that could crash virtualized clusters or silently alter sensitive financial records—a critical safeguard when dozens of VMs share the same memory pool. The registered signal buffer stabilizes command and address lines, allowing you to fully populate all memory channels at maximum speed without signal degradation. For an in-memory database like Redis or SAP HANA, this means confidently scaling to terabytes of error-free, low-latency storage. The dual-rank x8 architecture interleaves access across internal banks, significantly boosting bandwidth under heavy concurrency; in a virtualized environment running hundreds of containers, that translates to tighter response times and smoother multitasking. And because it operates at power-efficient 1.1V, you reduce data center energy draw without sacrificing the 4800MT/s throughput that accelerates critical workloads. This RDIMM turns technical specifications into tangible uptime and speed.
General Virtualization
For a typical dual-socket virtualization host, install a balanced set of these 32GB RDIMMs across all memory channels—ideally one or two DIMMs per channel (1DPC or 2DPC). Populating 8 to 16 modules delivers 256GB to 512GB of total capacity, comfortably supporting dozens of general-purpose VMs while preserving memory bandwidth through uniform channel loading. Always leave a few slots free to accommodate future growth without a complete rebuild.
In-Memory Database
In-memory databases demand maximum capacity and reliable throughput, so populate every available channel with these registered ECC modules. Using 16 or 24 modules in a dual-socket server provides 512GB to 768GB, allowing large datasets to reside entirely in RAM. The dual-rank x8 organization improves rank interleaving, which boosts effective bandwidth under the sustained, latency-sensitive workloads typical of Redis, SAP HANA, or Memcached deployments.
High-Performance Computing
HPC clusters require consistent, high-speed memory access across all cores. Fill each CPU’s memory channels symmetrically with one or two 32GB RDIMMs—commonly 16 modules per node for 512GB total. This configuration sustains DDR5-4800 speeds while feeding many-core processors with enough capacity for simulation meshes and parallel I/O. Uniform population eliminates NUMA imbalances and delivers the predictable latency essential for tightly coupled parallel jobs.
Rigorously tested, this RDIMM is compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo SR650 V3.
Q: Can I mix this M321R4GA3BB0-CQKDG with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for server RDIMMs. Mismatched modules can cause instability, signal integrity issues, and system errors. Use identical modules for guaranteed compatibility.
Q: Is this memory compatible with my system?
A: This DDR5 RDIMM is designed for servers supporting Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC (Genoa) platforms. Verify your server's qualified vendor list for this specific module.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard guide. Generally, populate one DIMM per channel first, balancing capacity across memory controllers to maximize bandwidth and ensure uniform cooling for reliable operation.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant registered server module, engineered for stability and data integrity. Overclocking and XMP are not supported to ensure 24/7 enterprise reliability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Its error-correcting design delivers industry-standard low annualized failure rates, meeting the rigorous reliability demands of server environments.
