Engineer's Note

This DDR5-6400 RDIMM with 48 GB capacity and integrated ECC is purpose-built for enterprise servers running memory-intensive workloads like virtualization and in-memory databases. Its registered signal type and dual-rank x8 organization deliver stable, high-bandwidth operation at 1.1 V, while ECC aggressively corrects data errors to safeguard transactional integrity.

Technical Specs & Insights

1. The 48 GB capacity per module maximizes memory density in dual-socket servers, enabling more virtual machines and larger in-memory databases without sacrificing channel count.
2. DDR5 technology doubles the burst length over DDR4, feeding modern server CPUs with the sustained bandwidth essential for AI inference and real-time analytics workloads.
3. 6400 MHz speed accelerates data-intensive transactions, reducing latency in financial trading platforms and ensuring responsiveness in high-frequency OLTP environments.
4. On‑die ECC and side‑band ECC work together to neutralize single‑bit errors, preserving data integrity in long‑running scientific simulations and mission‑critical cloud services.
5. The registered signal architecture stabilizes heavy multi‑DIMM configurations, allowing fully populated memory channels to operate reliably under 24/7 enterprise uptime requirements.

Why These Specs Matter

Designed for modern data center workloads, the MTC20F208XS1RC64BB1 is a registered DDR5 server memory module, instantly identifiable by its RDIMM form factor, ECC capability, and registered signal type. When you are running a dense virtualization cluster hosting dozens of mission-critical VMs, a single undetected bit flip can cascade into hypervisor crashes and silent data corruption. The on-die ECC and side-band ECC engine in this module actively scrub and correct such errors, preserving computational integrity across your entire virtualized environment. Its registered architecture buffers command and control signals, enabling the deployment of large-capacity 48 GB DIMMs without compromising signal stability—a critical advantage when you need to maximize memory density for a memory database like SAP HANA or a high-throughput Redis cluster. The dual-rank x8 organization further amplifies real-world performance by allowing the memory controller to interleave accesses across two internal ranks, unlocking higher sustained bandwidth at 6400 MT/s. This translates directly into faster query responses and lower latency under the concurrency demands of in-memory analytics. Operating at a power-efficient 1.1 V, it helps reduce overall server energy consumption without sacrificing the reliability your business depends on.

Endurance & Reliability

General Virtualization
Populate one 48 GB RDIMM per memory channel to achieve balanced bandwidth and low latency. On a typical 8-channel server platform, this yields 384 GB, comfortably hosting over 50 general-purpose VMs while ECC ensures data integrity. For denser consolidation, installing two DIMMs per channel (768 GB) is viable if the platform maintains the targeted 6400 MT/s speed.

In-Memory Database
In-memory databases like Redis or SAP HANA demand large capacity and low latency. Leverage the dual-rank design by fitting two 48 GB DIMMs per channel; a dual-socket server with 16 slots reaches 768 GB, keeping massive table sets in memory. Verify that the CPU memory controller supports 6400 MT/s at 2DPC to avoid bandwidth throttling and preserve transaction throughput.

High-Performance Computing (HPC)
HPC workloads prioritize maximum bandwidth. Install one 48 GB DIMM per channel to sustain the full 6400 MHz clock. A dual-socket node with 12 memory channels per CPU and 24 modules provides 1152 GB, eliminating memory bottlenecks in CFD simulations and MPI-based codes. The dual-rank x8 configuration further amplifies effective streaming bandwidth.

Verified Compatibility

This server memory is validated for Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, and similar systems.
