This 48GB DDR5-6400 Registered ECC module, with its Single Rank x4 configuration, minimizes rank contention to deliver consistent low-latency performance ideal for memory-intensive server workloads like virtualization and in-memory databases, while the registered signal buffering ensures robust data integrity at high speeds. Its 1.1V operation and ECC reliability make it a strong fit for scaling enterprise platforms without compromising stability.
1. The 48 GB non-binary module density allows granular memory scaling, letting a single server host more virtual machines without stranding precious capacity or consuming extra power.
2. ECC protection eliminates single-bit errors in real time, safeguarding data integrity for transactional databases and long-running analytics that cannot tolerate silent corruption.
3. Registered signal buffering isolates DRAM loading from the CPU memory bus, enabling multiple high-capacity DIMMs per channel while preserving signal integrity in dense rack deployments.
4. 6400 MT/s sustained bandwidth accelerates in-memory workloads and parallel data streams, directly reducing query response times in virtualized and containerized environments.
5. Single Rank x4 organization maintains low per-channel electrical loads, ensuring the memory subsystem stays at full rated speed even with all slots populated for maximum capacity.
Designed for the modern data center, the Micron MTC20F104XS1RC64BB2R is a DDR5-6400 Registered DIMM that directly addresses the critical pain points of IT infrastructure managers. Its four standout features translate into tangible uptime and performance gains. First, integrated ECC automatically corrects single-bit memory errors caused by cosmic radiation or electrical noise, preventing silent data corruption that could crash a financial transaction database or produce faulty analytics in an AI training run. Second, the onboard register buffers command and address signals, enabling a single server to support massive 48GB modules across all channels without signal degradation. This is essential when you run memory-hungry virtualization clusters—hosting dozens of VMs on one node requires the stability to allocate large memory pools confidently. Third, the single-rank x4 organization and low 1.1V voltage enhance signal integrity and thermal efficiency, allowing the 6400MT/s bandwidth to sustain linear performance scaling in in-memory databases like Redis or SAP HANA, where microsecond latency spikes directly impact user experience. Finally, at 48GB per stick, this module breaks the traditional capacity barriers, letting you maximize density in constrained server footprints for containerized microservices that demand vast, reliable memory. For your mission-critical workloads, this RDIMM means fewer silent failures, denser consolidation, and consistently low latency under pressure.
General Virtualization
For a DDR5-6400 registered DIMM, this 48 GB capacity strikes an excellent balance between density and cost for virtualized hosts. We recommend populating servers with a minimum of four modules (192 GB total) to leverage quad-channel memory architectures, allowing comfortable overcommit ratios for mixed-application VMs while maintaining ECC protection and high bandwidth.
In-Memory Database
The low 1.1V voltage and single-rank x4 design make this module an efficient choice for memory-hungry databases like Redis or SAP HANA. Install six or eight identical modules to reach 288–384 GB in a balanced NUMA configuration, ensuring the entire dataset or hot partition resides in memory and benefit from the 6400 MT/s speed for minimal latency.
High-Performance Computing
HPC workloads demand maximum per-core bandwidth and data integrity. Deploy this RDIMM across all memory channels—typically 8 or 12 modules per node—to fully saturate the processor’s memory controller. The CAS 52 latency at 6400 MHz is well-suited for simulation and modeling codes, providing the ECC and registered signaling necessary for stability during long-running parallel jobs.

Q: Can I mix this MTC20F104XS1RC64BB2R with other DDR5 RDIMMs of different brands or speeds in the same server?
A: Mixing is not recommended. Even with identical specs, variances in signal integrity and timing can compromise registered ECC functionality. For guaranteed stability, use identical modules across all channels.
Q: Is this 48GB DDR5 RDIMM compatible with my Intel Xeon Scalable or AMD EPYC server platform?
A: Compatibility depends on the platform’s memory reference code support for 48GB single-rank x4 RDIMMs. It is designed for latest-generation servers; validate via system vendor’s qualified vendor list for your specific CPU and BIOS revision.
Q: What is the recommended DIMM population order for optimal performance with this module?
A: Populate identical modules per channel following your server’s memory slot numbering guidelines. Typically, balance capacity across memory controllers and populate 1 DIMM per channel first, then second, to maximize interleaving and bandwidth.
Q: Does this registered ECC module support overclocking or XMP profiles?
A: No. As a server-grade registered ECC RDIMM, it operates strictly at JEDEC standard DDR5-6400 timings. It does not support overclocking, XMP, or any other performance profile beyond validated specifications.
Q: What warranty and typical failure rate can I expect for this memory module?
A: It carries a 1-year warranty. Enterprise-class registered RDIMMs typically exhibit an annualized failure rate below 0.5% under specified conditions, ensuring high reliability for mission-critical workloads.
