This DDR5-4800 Registered ECC DIMM with dual-rank x8 organization is engineered for enterprise servers and memory-intensive workloads such as virtualization and in-memory databases, where its integrated ECC and registered signal buffering ensure robust data integrity and reliable operation under heavy load. The dual-rank configuration boosts interleaving efficiency to improve overall memory bandwidth, while the low CL40 latency at 4800 MT/s balances speed with the stability demanded by mission-critical platforms.
1. Error Correction Code detects and silently corrects single-bit memory faults on the fly, preserving the integrity of transactional databases and preventing costly downtime in financial services.
2. The registered clock driver re-drives address and command signals across the module, stabilizing massive memory footprints that underpin dense virtualization clusters without signal degradation.
3. Dual Rank x8 organization interleaves internal banks for parallel access, consistently saturating the memory channel to accelerate large in-memory analytics and database query throughput.
4. A 32GB capacity per module triples the per-channel memory density compared to typical enterprise DIMMs, directly enabling higher VM consolidation ratios and larger cache tiers on power-efficient 1U nodes.
5. DDR5 technology with its doubled bank groups and on-die ECC delivers the bandwidth necessary to keep modern multi-core server CPUs fed, removing data bottlenecks in real-time AI inference pipelines.
Whether you are consolidating virtual machines or running a lightning-fast in-memory database, the M321R4GA3BB0-CQKVG RDIMM’s four defining characteristics directly impact uptime and throughput. Its hardware ECC scrubs single-bit errors induced by cosmic radiation or silicon aging, preserving data integrity so a flipped bit won’t silently cascade into a corrupted customer order. The registered clock buffer guarantees rock-solid signal integrity across fully populated memory channels, eliminating the frustrating intermittent crashes common in dense virtualization hosts. Dual-rank organization interleaves internal banks to nearly double the memory-level parallelism, feeding your SAP HANA instance the sustained bandwidth it craves during complex aggregations. Finally, the DDR5-4800 interface at a cool 1.1V delivers 50% more bandwidth than DDR4-3200 without thermal penalty, meaning higher sustained performance for your entire server fleet. With this module, you aren’t just buying RAM; you are commissioning a foundation for always-available services.
This is a DDR5-4800 registered ECC RDIMM, designed exclusively for server-class platforms. Its 32 GB capacity, dual-rank x8 organization, and error correction make it ideal for mission-critical workloads. Below are capacity planning recommendations for typical server scenarios.
General Virtualization
For a dual-socket virtualization host, populate balanced memory across all channels to maximize bandwidth. Start with one 32 GB DIMM per channel (8 modules total) to achieve 256 GB, comfortably supporting dozens of general-purpose VMs. Scale to 16 modules for 512 GB when hosting heavy or memory-overcommitted tenants.
In-Memory Database
In-memory databases demand both high capacity and unwavering data integrity. Fill every channel with this 32 GB RDIMM—typically 16 or 24 modules—to reach 512 GB or 768 GB per node. ECC protection guards against bit flips during massive in-memory sorts, while the registered interface ensures signal stability at full population.
High-Performance Computing (HPC)
HPC favors balanced throughput over raw capacity. Equip one DIMM per memory channel (8 modules, 256 GB) to preserve peak 4800 MT/s speed and minimize latency. For memory-bandwidth-bound simulations, populate a second DIMM per channel to 512 GB, leveraging dual-rank interleaving for a slight parallel-access advantage.
Proven reliable after rigorous testing, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, etc.
Q: Can I mix this M321R4GA3BB0-CQKVG with other memory modules of different brands or speeds?
A: Mixing brands or speeds is not recommended for server RDIMMs. It can cause signal integrity issues, instability, or POST failures. For guaranteed compatibility, use identical part numbers with the same rank, CAS latency, and voltage.
Q: Is this memory compatible with my system?
A: This DDR5-4800 ECC Registered RDIMM is designed for servers supporting 4th Gen Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004/7003 Series platforms. Verify your motherboard’s qualified vendor list for this 288-pin, 1.1V module.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server’s technical manual; optimal order maximizes memory channels and interleaving. Typically, populate one DIMM per channel symmetrically, starting from slots furthest from the CPU. Balanced population ensures full bandwidth and rank interleaving benefits.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server RDIMM, prioritizing data integrity and 24/7 reliability over overclocking. It operates at standard 4800MT/s with fixed CL40 timings and does not feature XMP or end-user overclocking capabilities.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise-grade RDIMMs exhibit extremely low annualized failure rates, typically under 0.1%, due to rigorous testing and ECC error correction, ensuring dependable, long-term operation in mission-critical environments.
