This 64GB DDR5-4800 Registered ECC RDIMM, featuring a dual-rank x4 organization and 1.1V low-voltage operation, is purpose-built for enterprise servers handling memory-intensive workloads such as virtualization, in-memory databases, and large-scale data analytics where uncompromising data integrity is paramount. Its registered signal buffering and ECC deliver exceptional electrical stability across fully loaded memory channels, while the dual-rank design maximizes interleaving to boost effective bandwidth under sustained multi-threaded loads.
1. DDR5 technology delivers significantly higher memory bandwidth, keeping latency-sensitive server tasks like real-time analytics and cache-intensive applications running smoothly under heavy loads.
2. A 64GB module capacity elevates memory density in constrained DIMM slots, allowing cloud platforms to pack more virtual machines per physical host without triggering costly NUMA imbalances.
3. ECC error identification safeguards data integrity by silently correcting single-bit faults, a non-negotiable requirement for financial ledgers, healthcare records, and long-running scientific simulations.
4. Registered signaling buffers the command and address lines, preserving electrical stability when populating multiple ranks and DIMMs, which is essential for maintaining uptime in expansive rack-scale deployments.
5. Dual Rank x4 configuration interleaves internal memory banks to fully saturate the channel, providing predictable throughput and reduced latency variance for virtualized users sharing the same physical server.
When a single undetected bit flip can corrupt an in‑memory database or crash a dozen virtual machines, no server component is more fundamental than its memory. The M329R8GA0BB0‑CQKEG is a 64 GB DDR5‑4800 registered DIMM with ECC, purpose‑built to eliminate those risks in demanding data‑center environments. Its ECC engine silently corrects single‑bit errors and detects multi‑bit corruption, which means a financial trading platform or a SAP HANA instance holding terabytes of hot data will never hand a wrong calculation to a user because of background radiation. The registered clock driver buffers command and address signals, allowing a single server board to populate all 32 DIMM slots with this 64 GB module for a total of 2 TB of stable memory — exactly what a dense virtualization cluster running dozens of containerized workloads needs to avoid boot‑time surprises. Built with a dual‑rank x4 organization, the module keeps all bank groups busy, delivering the sustained bandwidth that in‑memory analytics and real‑time inference engines require without stalling under concurrent access patterns. Operating at an efficient 1.1 V, it also helps a rack‑scale farm control thermal footprint and energy cost even when every slot is filled, making it a true foundation for always‑on enterprise services.
General Virtualization
This 64GB DDR5-4800 RDIMM balances capacity and bandwidth for dense VM consolidation. Populate servers with 8 to 16 modules to achieve 512GB–1TB, leveraging dual-rank x4 organization for high per-channel throughput. ECC and registered signaling ensure multi-tenant stability and reliable uptime.
In-Memory Database
For SAP HANA or Redis workloads, equip two-socket servers with 16 or more modules to build a 1–2TB fault-resilient memory pool. The entire dataset stays in RAM, while ECC and registered clocking guarantee integrity under sustained transactional loads. CL40 latency is entirely adequate for real-time analytics.
High-Performance Computing (HPC)
HPC applications demand sustained memory bandwidth. Install one DIMM per channel at 1DPC to preserve the full 4800MT/s speed. A dual-processor node with 16 modules delivers 1TB capacity, and the dual-rank design provides efficient, low-latency access that keeps compute cores fed during parallel simulations.

Q: Can I mix this M329R8GA0BB0-CQKEG with other memory modules of different brands or speeds?
A: Mixing modules is not advised for RDIMM servers. Different brands, speeds, or ranks can cause instability. For guaranteed compatibility, populate only with identical M329R8GA0BB0-CQKEG modules validated in your server's qualified vendor list.
Q: Is this memory compatible with my system?
A: This DDR5-4800 RDIMM is designed for Intel Xeon Scalable (Sapphire Rapids/Emerald Rapids) and AMD EPYC 9004/8004 platforms with DDR5 support. Verify your server’s memory QVL and BIOS update to ensure full compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s population guide. Typically, populate balanced configurations across memory channels, installing identical DIMMs per channel in 1DPC or 2DPC layouts to maximize interleaving and avoid performance penalties.
Q: Does this module support overclocking or XMP profiles?
A: No, this is an industry-standard registered server module operating exclusively at JEDEC DDR5-4800 with CL40 timings. It does not support XMP or overclocking, prioritizing data integrity and platform stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise-class 64GB DDR5 RDIMMs undergo rigorous screening, achieving an extremely low annualized failure rate (AFR) typically below 0.5%, ensuring mission-critical reliability.
