This 96GB DDR5-4800 registered DIMM with ECC is engineered for server-class platforms, excelling in memory-intensive workloads such as virtualization, in-memory databases, and large-scale data analytics where data integrity and high capacity are critical. Its registered signal type and dual-rank x4 organization enhance signal stability and interleaving efficiency, enabling reliable operation in dense multi-DIMM configurations while maintaining robust error correction and power efficiency at 1.1V.
1. 96GB capacity per module enables extreme memory density per server, supporting vast virtualization workloads and massive in-memory datasets without scaling out hardware.
2. ECC protection transparently corrects single-bit errors and detects multi-bit faults, preserving financial transaction integrity and preventing silent data corruption.
3. Registered signal buffering stabilizes command and address signaling across fully populated channels, ensuring reliable operation in multi-DIMM enterprise platforms.
4. Dual Rank x4 configuration interleaves accesses across internal rank groups, sustaining peak channel utilization for latency-sensitive, concurrent query processing.
5. DDR5 technology doubles the burst length and improves power efficiency, directly boosting throughput for real-time analytics and containerized microservices fleets.
The MM321RYGA0BB0-CQK is engineered as a server-class registered DDR5 DIMM, and its four defining characteristics directly address the critical demands of modern data centers. With a 96 GB capacity on a single module, it empowers dense virtualization clusters, allowing far more virtual machines per physical host without sacrificing memory bandwidth. This density is fortified by the registered signal type, which buffers command and address traffic, ensuring clean signal integrity across heavily populated server boards — so your hypervisor remains stable even under maximum load. The ECC capability goes beyond simple data protection; in an in-memory database like Redis or SAP HANA, a single undetected bit-flip can corrupt financial transactions or analytics results, and this module actively detects and corrects such errors, safeguarding data fidelity around the clock. Furthermore, its dual-rank x4 organization leverages interleaving to boost concurrent access efficiency, alleviating bottlenecks during high-throughput query processing. Operating at 4800 MT/s with a low 1.1 V power envelope, it delivers higher bandwidth per watt, which is vital for colocation environments where every unit of thermal and power budget must translate directly into reliable, revenue-generating performance.
General Virtualization
For dense virtualization hosts, deploy six of these 96 GB RDIMMs in a dual-socket server to reach 576 GB total memory, comfortably supporting over 100 moderate VMs. Distribute modules evenly across all memory channels to sustain 4800 MT/s speeds and avoid NUMA imbalances. This provides ample headroom for memory overcommitment while maintaining responsive live migration.
In-Memory Database
Populate all eight channels per socket with a single 96 GB DIMM each, yielding 768 GB per node at full speed—ideal for Redis or SAP HANA workloads. The Registered ECC design ensures data integrity during in-memory processing, and dual-rank x4 construction delivers strong bandwidth for key-value lookups. Scale out by adding identical nodes instead of mixing capacities.
High Performance Computing
Configure 16 modules (1.5 TB) across a dual-socket platform using balanced DIMM-per-channel ratios to maximize memory bandwidth per core. This arrangement feeds large parallel jobs without throttling, critical for CFD and genomic workloads. The 1.1 V low-power DDR5 operation also reduces thermal strain in dense compute clusters, enabling sustained turbo frequencies.

Q: Can I mix this MM321RYGA0BB0-CQK with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged in server environments. Registered DIMMs require identical ranks, timings, and organization to ensure signal integrity. Mismatched modules may cause instability or prevent boot.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This DDR5-4800 ECC Registered DIMM is designed for current-gen server platforms supporting RDIMMs, such as Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 series. Verify motherboard or vendor qualification for 96GB x4 rank configurations.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per memory channel, starting with the farthest slot from the CPU. Balance capacity across all populated channels and follow the server vendor’s slot numbering guide to maximize throughput and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise ECC Registered DIMM, this module operates strictly at JEDEC standard DDR5-4800 timings. Overclocking and XMP profiles are not supported and would compromise data integrity in mission-critical systems.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Registered DIMMs exhibit extremely low failure rates in qualified systems when operated within specified thermal and voltage limits, with a typical AFR below 0.5%.
