This 32GB DDR5-4800 Registered ECC RDIMM is purpose-built for server platforms, excelling in virtualization, in-memory databases, and data-intensive enterprise workloads where data integrity is paramount. Its dual-rank x4 organization improves memory bandwidth via bank interleaving, while the registered signal type ensures stable operation in high-capacity configurations and ECC proactively corrects single-bit errors to prevent data corruption.
1. Registered buffer reduces electrical loading on the memory controller, enabling stable operation across fully populated server channels in large-scale deployments.
2. ECC functionality safeguards transactional data integrity, preventing silent memory corruption that could crash virtual machines or financial databases.
3. High-capacity module design empowers dense virtualization, allowing more containers and guest instances per server node without sacrificing performance.
4. DDR5 technology delivers elevated bandwidth per core, accelerating real-time analytics and in-memory processing for data-intensive enterprise workloads.
5. Dual-rank x4 organization keeps memory banks deeply pipelined, sustaining throughput under heavy concurrent access typical of multi-tenant cloud environments.
Designed for the data center, the Samsung M321R4GA0BB0-CQKVG is a 32 GB DDR5-4800 Registered DIMM built to eliminate the risks that keep IT architects awake at night. In a dense virtualization cluster where dozens of VMs contend for memory, its integrated ECC silently corrects single-bit errors caused by cosmic radiation or silicon aging, preventing silent data corruption that could crash critical workloads or poison transactional databases. The registered clock driver stabilizes signal integrity across high-density configurations, so you can populate all channels with confidence and sustain 38.4 GB/s of bandwidth per module without compromising uptime. That throughput, coupled with the dual‑rank x4 organization that interleaves accesses for lower effective latency, turns in‑memory analytics platforms like SAP HANA or Redis clusters into responsive, real‑time engines. The 1.1 V operating voltage further shrinks the power envelope across a fleet of servers, meaning every rack delivers more compute per watt while safeguarding data integrity under relentless 24/7 operation. This is memory engineered for zero‑surprise enterprise reliability.
General Virtualization
A single 32GB RDIMM provides a solid foundation for light virtualization hosts, but modern hypervisors thrive on memory capacity. For a typical dual-socket server handling 20–30 mixed VMs, populate at least eight identical modules (256GB total) across both memory channels to balance capacity and NUMA-aware performance. Leverage the module’s dual-rank design to maximize interleaving and bandwidth per channel.
In-Memory Database
In-memory databases such as Redis or SAP HANA demand both low latency and high data integrity, making ECC Registered memory essential. Deploy six to twelve of these 32GB DDR5-4800 RDIMMs (192–384GB) in a 1 DIMM per channel (1DPC) configuration to sustain rated speed while avoiding rank contention. This layout guarantees error resilience and allows large datasets to reside entirely in RAM with fast CL40 access.
High-Performance Computing (HPC)
HPC workloads benefit from the combination of high bandwidth and reliable throughput. Install twelve 32GB dual-rank RDIMMs (384GB) across all memory channels of a dual-CPU node, ensuring a balanced 6+6 split for symmetric multiprocessing. The 4800MT/s speed and 1.1V low-power operation maintain thermal headroom during sustained parallel jobs, while registered ECC prevents silent data corruption during multi-day simulation runs.
Rigorously tested, compatible with servers such as Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3.
Q: Can I mix this M321R4GA0BB0-CQKVG with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. It may cause instability, force lower speeds, or disable ECC functionality. Always use identical modules for guaranteed reliability in server environments.
Q: Is this memory compatible with my system?
A: This DDR5-4800 ECC RDIMM fits servers supporting Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 series. Verify your motherboard’s QVL and chipset compatibility; 288-pin DDR5 slots are required.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules per channel following your server manual: typically 1 DIMM per channel first, then balance across memory controllers. Use Dual Rank x4 modules symmetrically to utilize all bus widths.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server RDIMM running at standard DDR5-4800 CL40. XMP and overclocking are not supported; it focuses on stability, data integrity, and ECC reliability for enterprise workloads.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Server-grade RDIMMs have very low annualized failure rates (typically <0.5%) under proper cooling. ECC further prevents silent data corruption.
