This ECC Registered DDR5-6400 DIMM is purpose-built for enterprise servers and memory-intensive workloads such as virtualization and in-memory databases, delivering a substantial 48 GB capacity per module to maximize memory density. Its dual-rank x8 organization and registered signaling ensure stable, high-throughput performance across fully populated memory channels, while integrated error correction safeguards critical data integrity.
1. A generous capacity per module enables dense memory configurations in 1U servers, maximizing the number of virtual machines per physical host without sacrificing memory bandwidth.
2. With a high data rate, this DIMM delivers the enormous memory bandwidth required for real-time analytics and high-frequency trading platforms, ensuring data pipelines never stall.
3. On-die ECC and side-band ECC functions protect against single-bit errors, preserving data integrity in mission-critical financial transactions and long-running scientific simulations.
4. Registered logic buffers reduce electrical loading on the command/address bus, enabling large populations of high-capacity DIMMs in multi-socket servers without signal integrity degradation.
5. Dual Rank x8 organization interleaves accesses across internal rank groups, improving command-per-cycle efficiency and sustaining throughput under the heavy parallelism of in-memory databases.
The Micron MTC20F208XS1RC64BR is a 48GB DDR5-6400 Registered DIMM purpose-built for modern servers where data integrity, density, and sustained throughput are non-negotiable. Its on-die ECC silently corrects single-bit errors caused by background radiation or electrical noise, protecting your virtualized financial trading systems and healthcare databases from silent data corruption that could crash transactions or distort critical patient records. The registered clock driver buffers address and command signals, preserving clean signal integrity even when all DIMM slots are fully populated. For you, this means VMware or Kubernetes clusters can scale to terabytes of reliable memory without the instability that plagues unbuffered modules under heavy load. Thanks to a dual-rank x8 organization and 6400MT/s transfer rate, each module delivers 51.2 GB/s of bandwidth, dramatically lowering latency in memory-hungry in-memory databases like SAP HANA or Redis clusters that field millions of real-time queries per second. A low 1.1V operating voltage further reduces power draw per gigabyte, helping dense 1U/2U servers stay within tight thermal budgets while putting 48GB in a single slot. The result is fewer server nodes, reduced software licensing costs, and bulletproof consistency during peak virtual desktop or analytics workloads.
General Virtualization
This registered DDR5-6400 RDIMM with ECC is ideal for dense virtualization hosts. A single 48 GB module per channel allows balanced capacity in dual-socket servers; populate six or twelve identical modules to reach 288 GB or 576 GB while maintaining full memory bandwidth. Pair DIMMs symmetrically across memory channels to avoid NUMA penalties and ensure stable overcommit for dozens of VMs.
In-Memory Database
For Redis, Memcached, or SAP HANA, where data durability and speed are critical, ECC helps prevent silent bit-flip errors. Deploy six 48 GB RDIMMs in a single-socket platform for 288 GB of affordable in-memory capacity, or scale to twelve modules for 576 GB. Keep all channels populated identically to sustain the 6400 MT/s frequency under heavy read-write pressure.
High-Performance Computing
HPC workloads benefit from the high 6400 MT/s speed and registered buffering that stabilizes large memory populations. Eight modules deliver 384 GB per node, matching dual‑socket eight‑channel designs. Configure one DIMM per channel for maximum throughput in simulation and modeling codes; dual‑rank x8 organization ensures desirable rank interleaving without exceeding channel load limits.

Q: Can I mix this MTC20F208XS1RC64BR with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for RDIMM servers. Mismatched timings can cause instability and may void warranty. Use identical modules for guaranteed performance and reliability.
Q: Is this memory compatible with my system?
A: This DDR5-6400 registered ECC module is compatible with servers using Intel Xeon Scalable 4th/5th Gen or AMD EPYC 9004/9005 processors. Verify your motherboard supports 288-pin RDIMMs at this speed.
Q: What is the recommended DIMM population order for optimal performance?
A: To maximize memory bandwidth, populate all channels evenly with matching modules. For dual-socket servers, follow the manufacturer’s slot population guide, typically filling the farthest slot first per channel.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise-grade registered ECC module, it adheres strictly to JEDEC standards without XMP or overclocking support, ensuring mission-critical stability and data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Typical annualized failure rate (AFR) for premium DDR5 RDIMMs is below 0.5%, reflecting rigorous manufacturing and testing standards.
