This 64GB DDR5-4800 Registered ECC DIMM, configured as dual-rank x4, ensures robust signal integrity and data reliability for mission-critical server platforms. It is ideally suited for virtualization clusters and in-memory databases where low CAS latency enhances real-time processing, while the 1.1V operation and ECC protection maintain power efficiency and error-free data integrity at scale.
1. High per-module capacity allows dense server consolidation, running a greater number of memory-intensive virtual machines without hitting swap overhead.
2. Next-generation memory architecture dramatically raises per-channel bandwidth, keeping latency low for massive parallel analytics and in-memory datasets.
3. End-to-end ECC detection and correction prevents silent data corruption, a non-negotiable safeguard for financial ledgers and always-on enterprise databases.
4. Registered buffering stabilizes signal paths across fully populated DIMM slots, ensuring uninterrupted operation in blade centers and multi-node chassis.
5. Dual-rank interleaving hides access turnaround gaps, delivering consistent throughput even when simultaneous OLTP and batch workloads compete for resources.
The M329R8GA0BB0-CQK is a 64GB DDR5-4800 Registered ECC RDIMM built for mission-critical servers. Its ECC correction acts as a silent guardian, preventing bit-flip data corruption in virtualized clusters and in-memory databases—errors that would otherwise crash instances or smear financial records. The registered buffering and dual-rank x4 design ensure rock-solid signal integrity even when scaling memory to terabytes, enabling large-scale Redis or SAP HANA deployments without stability compromises. With 64GB per module and DDR5’s PC5-38400 bandwidth, it effortlessly handles dozens of VMs per host. The ultra-low CL4 CAS latency delivers near-instantaneous data access, critical for high-frequency trading platforms where microseconds of delay mean lost revenue. Operating at a low 1.1V, it also cuts power and cooling costs in dense racks. Whether you are consolidating a server farm or running a latency-sensitive analytics engine, this module translates into data reliability, scalable capacity, and performance that directly impacts business outcomes.
General Virtualization
For dense VM hosting, populate servers with 8×64GB RDIMMs (512GB total) distributed evenly across both memory controllers—one DIMM per channel (1DPC). This preserves full DDR5-4800 speed, avoids bandwidth penalties from dual-DPC configurations, and provides headroom for 40–60 typical VMs. Scale to 16 modules (1TB) in dual-socket systems when overcommit ratios exceed 3:1.
In-Memory Database
Memory-resident workloads like SAP HANA or Redis demand capacity and sustained latency. Install a minimum of 8 identical 64GB dual-rank x4 RDIMMs (512GB), again at 1DPC to keep CAS 40 timing tight. For large instances, expand to 16 modules (1TB) using all channels; the dual-rank x4 organization delivers higher row-hit rates and lower average latency compared to single-rank alternatives in OLTP-heavy scenarios.
High-Performance Computing
Balance bandwidth and capacity by fitting 8×64GB RDIMMs (512GB) per node, one per channel, to supply the 307 GB/s peak throughput of an 8-channel DDR5-4800 platform. For simulation codes with large working sets, double to 16 modules (1TB) while accepting a slight frequency drop if the platform forces 2DPC. Always match module part numbers across sockets to maintain symmetric interleaving and ECC reliability.

Q: Can I mix this M329R8GA0BB0-CQK with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not advised. It can cause instability or force all modules to the lowest speed. For server reliability, use identical modules.
Q: Is this memory compatible with my server?
A: This 64GB DDR5-4800 Registered ECC RDIMM works with servers supporting DDR5 RDIMM, like Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 series. Always check your system’s QVL.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, install this Dual Rank RDIMM in identical sets per channel, filling one DIMM per channel first, then the second. Follow your server’s population guidelines for balanced memory.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC module, it adheres to JEDEC DDR5-4800 standards. Overclocking and XMP are not supported, prioritizing data integrity and stability over higher frequencies.
Q: What warranty and typical failure rate can I expect?
A: This module is backed by a one-year warranty. Enterprise DDR5 RDIMMs typically exhibit an annual failure rate below 1%, given proper cooling and validated platforms.
