This 48 GB DDR5-6400 Registered ECC RDIMM is purpose-built for server environments running virtualization, in-memory databases, and mission-critical workloads where data integrity is non-negotiable. Its dual-rank x8 organization maximizes interleaving for sustained throughput, while the Registered signal type and CL52 low-latency timing ensure stable operation under heavy multi-DIMM configurations.
1. The 48GB per-module capacity enables denser memory configurations in rack servers without swapping for higher-capacity sticks, directly boosting virtual machine density per node.
2. A 6400MT/s DDR5 speed delivers a 51.2GB/s peak bandwidth per channel, which accelerates in-memory databases and real-time analytics under heavy parallel workloads.
3. On-die ECC capability corrects single-bit errors in real time, preserving transaction accuracy and preventing costly data corruption in always-on enterprise services.
4. The registered design buffers command and address signals, maintaining stable electrical timing across fully populated DIMM slots so that scaling up to multi-terabyte memory footprints remains reliable.
5. Dual Rank x8 organization employs per-channel interleaving to keep command pipelines saturated, yielding higher effective throughput for virtualization hosts and memory-caching applications.
The MTC20F208XS1RC64BB2 is a 48GB DDR5-6400 Registered ECC DIMM purpose-built for server workloads. In a dense virtualization cluster, ECC is not optional—it silently corrects single-bit memory errors induced by background radiation, preventing silent data corruption that could poison a financial transaction or database index without warning. The registered architecture buffers command and address lines, so you can populate all DIMM slots with 6400MT/s modules while maintaining rock-solid signal integrity; this translates to terabyte-scale memory pools required to run hundreds of VMs on a single host without performance degradation. For in-memory databases like SAP HANA or Redis, the 48GB capacity paired with a dual-rank layout enables rank interleaving, allowing the memory controller to hide access latencies and sustain full 51.2 GB/s bandwidth under heavy analytical loads. Every millisecond saved during a large table scan directly accelerates real-time decisions. This module delivers both uncompromising data integrity and the massive, fast memory footprint that modern virtualized and data-intensive applications demand.
Based on the specifications—DDR5-6400, ECC, Registered (RDIMM), 48 GB capacity, and 1.1V—this module is engineered for server platforms. It fits modern dual-socket systems demanding high signal integrity and large memory footprints. Below is workload-specific capacity planning guidance.
General Virtualization
Virtualization thrives on high capacity and balanced bandwidth. Populating one of these 48 GB RDIMMs per memory channel (1DPC) on an 8-channel server CPU yields 384 GB per socket, comfortably supporting dozens of mixed-load VMs. The registered design preserves full 6400 MT/s speed, supplying the throughput needed for live migration and memory overcommit scenarios without throttling.
In-Memory Database
For databases like SAP HANA or Redis, capacity and latency are paramount. Install 24 of these modules across a dual-socket board with 12 channels per CPU to reach 1,152 GB, storing large datasets entirely in RAM. The Dual Rank x8 organization and 1DPC operation maintain CL52 latency and 6400 MHz, accelerating in-memory analytics while ECC guards against data corruption.
High-Performance Computing (HPC)
Memory-bandwidth-bound HPC codes require balanced channel population. Deploy the 48 GB RDIMMs uniformly—one per channel across a 16-channel dual-socket node—delivering 768 GB and maximum aggregate bandwidth. This configuration sustains 6400 MT/s for simulation or modeling codes, where the low 1.1V power and Registered signaling ensure reliable, high-speed operation during sustained parallel runs.

Q: Can I mix this MTC20F208XS1RC64BB2 with other memory modules of different brands or speeds?
A: Mixing is not recommended. For server reliability, all DIMMs should be identical in brand, speed, rank, and timings. Mismatched modules can compromise signal integrity and lead to instability.
Q: Is this memory compatible with my server platform?
A: This 48GB DDR5-6400 ECC Registered RDIMM is designed for servers with Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 CPUs supporting DDR5-6400 RDIMMs. Please check your system's memory QVL.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, filling all memory channels symmetrically as per your server manual. Balanced dual-rank configurations maximize bandwidth and interleaving for peak performance.
Q: Does this module support overclocking or XMP profiles?
A: No. Server ECC RDIMMs adhere to JEDEC DDR5-6400 standards and do not support overclocking or XMP, ensuring data integrity and long-term stability in mission-critical environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise DDR5 RDIMMs exhibit extremely low annualized failure rates, typically well below 1%, when operated within specified environmental conditions.
