This 64GB DDR5-4800 Registered ECC RDIMM is designed for modern server platforms, excelling in virtualized environments, in-memory databases, and data-critical workloads where integrity and uptime are paramount. Its dual-rank x4 configuration boosts throughput via rank interleaving, while registered signal buffering and ECC deliver exceptional signal stability and reliable single-bit error correction across dense memory channels.
1. 64GB high-density module enables massive memory pools for enterprise virtualization, packing more VMs per node without sacrificing performance.
2. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption that could crash critical financial or scientific workloads.
3. The register buffer stabilizes high-capacity configurations, allowing fully loaded multi-DIMM servers to run 24/7 without signal integrity issues.
4. Dual-rank interleaving bolsters memory-level parallelism, sustaining peak throughput for in-memory analytics and large database queries under concurrent user loads.
5. 4800MT/s DDR5 bandwidth turbocharges data-intensive tasks, slashing latency in real-time AI inference and high-frequency trading applications.
The Samsung M321R8GA0BB0-CQKVG is a 64GB DDR5 Registered DIMM purpose-built for enterprise servers, where its four core attributes directly solve your data center’s most pressing reliability and density challenges. First, the 64GB capacity on a single module, enabled by high-density DDR5 technology, lets you maximize memory per server node—vital for virtualization clusters running dozens of VMs, where every additional gigabyte prevents costly resource contention and extends workload consolidation. Second, integrated ECC continuously corrects single-bit errors, a silent threat that can corrupt database transactions or analytics results; in an in-memory database like Redis or SAP HANA, this means absolute data integrity without unexpected system halts. Third, the Registered buffer architecture cleans and re-drives signals, guaranteeing stable operation even when all memory channels are fully populated. This allows a financial trading platform to scale memory capacity seamlessly without signal degradation or crashes during peak transaction volumes. Finally, operating at a mere 1.1V, this DDR5 module cuts power consumption and thermal output across a 24/7 server fleet, lowering cooling overhead while sustaining 4800MT/s throughput. For you, that translates into higher uptime, uncompromised data fidelity, and significantly lower total cost of ownership in demanding enterprise environments.
General Virtualization
This 64GB DDR5-4800 RDIMM is ideal for dense virtualization hosts. Deploy a balanced configuration of 8 or 16 identical modules across all memory channels (e.g., 8 x 64GB for 512GB total) to maximize memory bandwidth and avoid NUMA penalties in dual-socket servers. The Registered ECC design ensures data integrity for dozens of concurrent VMs, while the dual-rank x4 organization provides the latency and throughput needed for hypervisor memory overcommit.
In-Memory Database
For in-memory databases like SAP HANA or Redis, capacity and reliability are paramount. Populate all available DIMM slots with these 64GB dual-rank RDIMMs to reach 1TB or more per node, ensuring the entire dataset resides in RAM. ECC protection guards against silent data corruption during sustained high-throughput operations, and the 4800MT/s speed balances cost with the low-latency demands of real-time analytics.
High-Performance Computing (HPC)
In HPC clusters, memory bandwidth per core is critical. Install these modules in a balanced population per socket—typically 8 or 16 DIMMs—to fully utilize the processor’s memory channels. The Registered ECC and dual-rank x4 configuration deliver the stability required for week-long simulation runs, while 64GB per stick allows large problem sizes without sacrificing the channel interleaving that accelerates vectorized math libraries.

Q: Can I mix this M321R8GA0BB0-CQKVG with other memory modules of different brands or speeds?
A: Mixing is not recommended. Registered ECC modules demand identical specs for stability. Mismatched speeds or brands can cause POST failures or data corruption on server platforms. Always use matching kits.
Q: Is this memory compatible with my server system?
A: This 64GB DDR5-4800 RDIMM is designed for Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series platforms. Please consult your server board’s Qualified Vendor List for exact model validation.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. Generally, populate identical DIMMs per channel starting farthest from the CPU. Balance dual-rank modules across channels to maximize interleaving and memory bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade Registered ECC module strictly adhering to JEDEC DDR5-4800 standards. Overclocking and XMP are disabled to ensure data integrity and 24/7 mission-critical reliability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Built with premium components and rigorous screening, its enterprise-class design yields an annualized failure rate typically below 0.5% under specified operating conditions.
