This 48 GB DDR5-6400 RDIMM with ECC and registered signaling is purpose-built for server platforms handling memory-intensive workloads such as virtualization and in-memory databases, where its dual-rank x8 configuration maximizes interleaving for higher bandwidth and its CL52 latency ensures snappy data access.
The 1.1 V operating voltage and 288-pin ECC design deliver exceptional power efficiency and end-to-end data integrity, making it ideal for mission-critical enterprise environments that demand rock-solid reliability.
1. A 48 GB capacity per module dramatically increases memory density per server node, allowing more virtual machines or containers to run concurrently without costly scale-out expansions.
2. DDR5-6400 speed delivers exceptionally high memory bandwidth, accelerating in-memory databases and real-time analytics where rapid data throughput is non-negotiable.
3. ECC protection actively detects and corrects single-bit errors, preserving data integrity in long-running financial or scientific compute workloads where silent corruption is unacceptable.
4. Registered signal architecture stabilizes command and address buses under heavy DIMM population, maintaining reliable operation in fully-loaded platforms with multiple modules per channel.
5. Dual Rank x8 organization keeps memory banks highly utilized and interleaved, sustaining peak bandwidth efficiency and consistent latency during mixed read/write storms in multi-tenant environments.
Understanding that the MTC20F208XS1RC64BB2R is a 48GB DDR5-6400 RDIMM immediately places it in the server memory category, where reliability under relentless workloads isn't a luxury — it’s a requirement. In a dense virtualization cluster hosting dozens of VMs, bit flips caused by background radiation can silently corrupt guest operating systems. The integrated ECC function actively detects and corrects such errors before they cascade into data loss or unexpected downtime, preserving the integrity of your entire virtualized estate. In parallel, the Registered signal type and 1.1V DRAM design buffer command signals across fully populated servers, so you can scale to terabytes of memory across 12 or 24 DIMM slots without sacrificing signal quality or stability. When an in-memory database like Redis or SAP HANA is serving financial transactions, the dual-rank x8 architecture interleaves data accesses to raise effective bandwidth, while the 6400MHz clock speed cuts response latency. What this means for you is a single DIMM that delivers clean, high-throughput data streams, guards against silent corruption, and maintains operational certainty — allowing your database queries and VM fleet to run with uncompromised consistency.
General Virtualization
For dense virtualization hosts, this 48 GB DDR5-6400 Registered ECC module fits perfectly. Deploy six or eight identical modules in a dual-socket server to reach 288–384 GB per node, enabling hundreds of VMs with strong memory overcommit and error resilience. The high 6400 MHz speed and dual-rank design reduce latency spikes under multi-tenant workloads.
In-Memory Database
Large in-memory platforms like Redis, Memcached, or SAP HANA demand both capacity and integrity. Start with four of these 48 GB RDIMMs per CPU to fill a channel with 192 GB, then scale to eight modules for 384 GB per socket. ECC protection guards against bit flips in real-time analytics, while registered buffering stabilizes signal quality at full population.
High-Performance Computing
Memory-bandwidth-bound HPC jobs thrive on this module’s DDR5-6400 speed and dual-rank x8 construction. Populate all eight channels of a single-socket server with one module each to hit 384 GB and maximize bandwidth. Combined with CL52 registered timing, it sustains high throughput for CFD, weather modeling, or genomic assembly without compromising data integrity.
Validated for DDR5-6400 RDIMM servers like Dell PowerEdge R770, HPE DL380 Gen12, Lenovo SR650 V4, and more.
Q: Can I mix this MTC20F208XS1RC64BB2R with other memory modules of different brands or speeds?
A: Mixing RDIMMs from different vendors or with varying speeds is not recommended for server environments. It may impair signal integrity and cause system instability or unbootable configurations.
Q: Is this memory compatible with my Intel Xeon Scalable or AMD EPYC server platform?
A: This DDR5-6400 registered ECC module targets platforms like 4th Gen Xeon Scalable (Sapphire Rapids) supporting 6400 MT/s. Verify CPU and motherboard support for 48 GB RDIMMs and dual-rank x8 DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel starting with the farthest slot. For dual-socket systems, balance memory across processors and fill channels symmetrically per the server manual to enable interleaving and full bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant registered DIMM operating at standard voltage and latency. Server memory does not support XMP or overclocking; it runs solely at specified 6400 MT/s with CL52 for platform-level reliability.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. As a qualified server-grade RDIMM with ECC and stringent testing, its annualized failure rate (AFR) is extremely low, typically under 0.5% under proper environmental conditions.
