The Micron MTC20F208XS1RC56BB2 48GB DDR5 Memory

The Micron MTC20F208XS1RC56BB2 48GB DDR5 Registered DIMM represents a high-capacity, enterprise-focused memory category designed for modern server and workstation platforms. This category centers on DDR5 RDIMM technology, which introduces major architectural improvements over previous DDR4 generations. Registered DIMMs integrate a register clock driver between the memory controller and DRAM chips, significantly improving signal integrity and allowing higher memory densities, increased channel scalability, and enhanced stability under sustained workloads.

DDR5 Technology and Performance Advantages

DDR5 SDRAM introduces significant architectural improvements over previous memory generations. With increased data transfer rates, improved power efficiency, and enhanced channel management, DDR5 memory is purpose-built for next-generation computing workloads. This 48GB module leverages these benefits to provide smoother multitasking, faster data access, and improved overall system responsiveness.

Memory Speed and Bandwidth

Operating at an effective speed of 5600MT/s, this DDR5 module complies with the PC5-44800 standard, ensuring high throughput for demanding applications. The elevated bandwidth allows servers and professional systems to process large datasets efficiently without bottlenecks.

High-Capacity 48GB DDR5 RDIMM Configuration

This memory category emphasizes advanced capacity optimization with 48GB per module, a capacity point that bridges traditional 32GB and 64GB modules. The 48GB form factor enables flexible memory scaling, allowing system architects to maximize total memory capacity without fully populating all available DIMM slots. This configuration is particularly valuable in dense server environments where memory bandwidth and capacity must be balanced with power efficiency and thermal constraints.By utilizing advanced DRAM die stacking and high-density chip layouts, DDR5 48GB RDIMM modules provide expanded memory footprints while maintaining JEDEC compliance. This capacity tier is ideal for virtualization hosts, in-memory analytics platforms, and database servers requiring large memory pools without excessive slot consumption.

DDR5 5600MHz Performance and Bandwidth Advantages

Operating at 5600MHz (PC5-44800), this DDR5 Registered memory category delivers substantial bandwidth improvements compared to previous DDR4 RDIMM solutions. With a theoretical bandwidth of 44.8GB/s per module, DDR5 5600MHz memory supports data-intensive workloads that demand rapid access to large datasets and parallel processing efficiency.

Registered DIMM

The registered signal processing design improves electrical stability by buffering address and command signals. This feature is particularly beneficial in multi-DIMM configurations, where maintaining signal integrity is critical for consistent performance and system reliability.

Optimized CL46 Latency

With a CAS latency of CL46, this memory category is tuned to balance high frequency operation with stable timing performance. While raw latency values are higher than those of lower-frequency modules, the overall effective latency is offset by DDR5’s significantly increased bandwidth and improved parallelism. For enterprise workloads, this balance results in faster data processing, reduced queuing delays, and improved application responsiveness.

Registered DIMM Signal Integrity Benefits

The registered design incorporates a register clock driver that buffers command and address signals, reducing electrical load on the memory controller. This buffering allows systems to support more memory modules per channel while maintaining stable operation at higher frequencies. As a result, DDR5 RDIMM memory is the preferred choice for multi-socket servers and high-density memory configurations.

288-Pin DDR5 RDIMM Form Factor Compatibility

This memory category adheres to the 288-pin DDR5 RDIMM form factor, ensuring compatibility with modern server platforms designed for DDR5 technology. While DDR5 modules share the same pin count as DDR4, the physical keying and electrical layout differ, preventing accidental cross-installation and ensuring proper system integration.The standardized form factor simplifies system upgrades and maintenance, allowing data center operators to deploy high-capacity DDR5 RDIMM modules across compatible platforms with confidence. This consistency supports scalable infrastructure growth and long-term hardware planning.

Power Efficiency and Thermal Optimization

Power efficiency is a critical consideration in modern data centers, and DDR5 technology introduces several enhancements to reduce energy consumption. Operating at a lower voltage of 1.1V, DDR5 RDIMM modules consume less power per bit transferred, contributing to reduced operational costs and improved thermal management.Integrated power management ICs (PMICs) on DDR5 modules enable more precise voltage regulation, improving efficiency and stability. This localized power control minimizes voltage fluctuations and supports consistent performance under variable workloads.

Dual-Rank Memory Organization

DDR5 RDIMM modules in this category often utilize dual-rank memory organization, which enhances memory interleaving and improves overall throughput. Dual-rank configurations allow the memory controller to alternate access between ranks, reducing idle cycles and improving effective bandwidth utilization.

Future-Proofing Server Platforms

Adopting DDR5 Registered memory positions organizations to take advantage of future processor and platform advancements. As CPUs continue to increase core counts and memory bandwidth requirements, DDR5 RDIMM modules provide the scalability needed to support next-generation workloads.The 48GB capacity point offers flexibility for incremental upgrades, allowing systems to expand memory capacity without complete hardware overhauls. This future-ready approach helps organizations protect their infrastructure investments while maintaining competitive performance.
