This 96GB DDR5-4800 RDIMM with ECC and registered signaling is purpose-built for server platforms running memory-intensive workloads such as virtualization, in-memory databases, and mission-critical enterprise applications where data integrity is paramount. Its dual-rank x4 organization enhances memory bandwidth utilization and interleaving efficiency, while the registered architecture ensures robust signal integrity in high-density multi-DIMM configurations.
1. The high-capacity module enables significant memory population per server, allowing dense virtualization and smoother in-memory database operations without frequent data swaps.
2. DDR5 technology delivers substantially higher bandwidth, accelerating parallel analytics and AI inference workloads that demand rapid movement of large datasets.
3. On-die ECC and side-band error correction proactively resolve bit-flip errors, preserving data integrity for mission-critical financial transactions and long-running compute tasks.
4. Registered signal architecture with a command/address buffer stabilizes signal integrity across fully loaded channels, essential for scaling memory without compromising uptime in multi-socket servers.
5. Dual Rank x4 organization interleaves access across internal banks to keep data channels saturated, sustaining predictable low-latency performance under heavy consolidation of virtual machines.
The M321RYGA0BB0-CQK is a 96GB DDR5 Registered DIMM purpose-built for modern data centers, and its four signature characteristics directly address the most pressing challenges in enterprise computing. Integrated ECC error correction actively detects and repairs single-bit errors, which is non-negotiable in dense virtualization clusters—a silent bit flip can corrupt a hypervisor and crash dozens of virtual machines or compromise financial ledgers. The registered signal buffer decouples the memory controller from the DRAM load, enabling multiple high-capacity modules per channel without signal degradation; this rock-solid stability is what allows you to confidently scale memory pools into the terabyte range for in-memory databases like SAP HANA, where an entire business dataset must reside faultlessly in RAM. The dual-rank x4 architecture leverages rank interleaving to amplify sustained bandwidth, meaning while one rank processes a transfer the controller concurrently prefetches from the other, dramatically accelerating parallel queries across scores of virtualized instances. Meanwhile, the finely optimized Column Access Strobe latency slashes the initial access delay, delivering sharper responsiveness for latency-sensitive transactional workloads. Backed by a 1.1V power-efficient DDR5 interface, this module turns reliability, massive capacity, and consistent speed into operational certainty.
General Virtualization
Deploy this 96GB DDR5-4800 RDIMM in pairs for dual-channel or populate all channels of a modern server platform to maximize memory bandwidth. A configuration with 6 or 8 such modules delivers 576–768GB of capacity, easily supporting 50+ moderate VMs on a single host. Leverage the ECC and Registered features to ensure data integrity and stable hypervisor operation under sustained multi-tenant workloads.
In-Memory Database
For memory-resident databases like Redis or SAP HANA, use the full 96GB DIMMs across all memory channels, aiming for 768GB to 1.5TB total capacity in a 2-socket server. A balanced population (1 DIMM per channel) preserves the high frequency while the dual-rank x4 construction supplies the low latency needed for real-time analytics. This configuration enables entire datasets to reside in RAM, dramatically accelerating query throughput.
High-Performance Computing
Install 8 or 12 of these registered DIMMs per node to feed bandwidth-hungry HPC applications with 768GB–1.15TB of memory. A balanced, symmetric configuration across all memory controllers avoids NUMA bottlenecks during parallel simulations. With 4800MT/s speed and ECC protection, the setup sustains error-free computation for long-running cluster jobs in computational fluid dynamics or climate modeling.
Compatibility verified: rigorously tested for servers like Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3.
Q: Can I mix this M321RYGA0BB0-CQK with other memory modules of different brands or speeds?
A: Not recommended. Mixing server Registered DIMMs risks compatibility and stability. To ensure reliable ECC operation, always populate identical part numbers with the same rank, speed, and voltage across all channels.
Q: Is this memory compatible with my system?
A: This DDR5-4800 RDIMM ECC module is compatible with servers using Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004/8004 platforms. Verify that your motherboard supports Registered ECC DDR5 and 96GB DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Always follow your server board's population guide. Typically, populate one DIMM per memory channel first (often white or blue slots) to maximize interleaving, then fill remaining slots symmetrically for balanced bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant, enterprise-class Registered DIMM designed for mission-critical reliability. Overclocking and XMP profiles are not supported, ensuring stable operation at the rated DDR5-4800 CL4 specification.
Q: What warranty and typical failure rate can I expect?
A: The module includes a 1-year limited warranty. Built with premium components and rigorous screening, its annualized failure rate is extremely low, typical for server-grade ECC memory, providing dependable long-term operation.
