The Micron MTC20C2085S1EC56BA1R 32GB DDR5 Memory

The Micron MTC20C2085S1EC56BA1R 32GB DDR5 ECC Unbuffered UDIMM memory module belongs to the advanced DDR5 server and workstation memory category, designed to meet the evolving performance, efficiency, and reliability demands of modern computing environments. This category focuses on next-generation DDR5 SDRAM technology that delivers higher bandwidth, improved power efficiency, and enhanced error correction capabilities compared to previous DDR4-based memory solutions. DDR5 ECC UDIMM modules are widely adopted in entry-level servers, professional workstations, virtualization hosts, edge computing platforms, and data-centric applications where data integrity and sustained throughput are critical.

32GB Capacity Memory

A 32GB single-module capacity is well-suited for contemporary server and workstation environments. This capacity allows systems to handle demanding applications such as virtualization, large datasets, high-resolution media processing, and complex simulations. Using a single 32GB module also leaves room for future expansion, enabling flexible memory configurations.

DDR5 SDRAM Memory

DDR5 SDRAM represents a significant architectural leap forward in system memory design. Operating at 5600MHz with a PC5-44800 bandwidth rating, this category of memory modules enables substantially higher data transfer rates, supporting faster CPU-to-memory communication. The transition from DDR4 to DDR5 introduces higher per-pin bandwidth, on-die ECC for internal memory array stability, and a dual 32-bit channel architecture per module, which improves parallelism and efficiency. These advancements collectively allow DDR5 memory to handle increasingly complex workloads, higher core counts, and data-intensive operations without bottlenecks.

Advanced DDR5 Memory Technology

DDR5 SDRAM introduces substantial improvements over DDR4 by increasing memory bandwidth, optimizing power management, and supporting higher densities per module. The Micron DDR5-5600 UDIMM leverages these advancements to deliver faster data transfer rates, improved multitasking performance, and better scalability for future hardware upgrades.

Lower Operating Voltage and Power Efficiency

Operating at a reduced voltage of 1.1V, DDR5 ECC UDIMM memory modules contribute to lower power consumption and reduced thermal output. This efficiency is essential for modern data centers and workstation environments where energy costs and heat dissipation are ongoing concerns. The integration of on-module power management ICs (PMICs) allows for finer voltage regulation, enhancing signal integrity and improving power delivery stability across varying workloads.

Performance Optimization for Modern Systems

With a data rate of 5600MT/s and a dual-rank x8 design, this DDR5 memory module ensures efficient data access and improved multitasking performance. It supports high-throughput applications such as virtualization, database management, content creation, scientific computing, and enterprise software environments.

Unbuffered UDIMM Design

Unbuffered DIMMs, commonly referred to as UDIMMs, are designed without a register or buffer between the memory controller and the DRAM chips. This design allows for lower latency and faster direct communication, making ECC UDIMMs ideal for single-socket servers, entry-level enterprise systems, and professional workstations. The Micron DDR5 ECC UDIMM category balances performance and reliability while maintaining compatibility with a wide range of platforms.

Latency and Performance Benefits

With a CAS latency rating of CL46, this DDR5 memory category offers a balanced approach to latency and speed. While higher frequencies inherently introduce higher latency values, the increased bandwidth of DDR5 compensates by delivering more data per clock cycle. For workloads that rely on sustained throughput rather than ultra-low latency, CL46 DDR5 ECC memory provides optimal performance characteristics.

Platform Compatibility

DDR5 ECC UDIMM modules are designed to work with compatible processors and chipsets that support DDR5 memory and ECC functionality. This includes select server-grade and workstation-grade CPUs where ECC is enabled at the memory controller level. Proper compatibility ensures that ECC features are fully utilized and that the system operates within validated specifications for stability and performance.

Dual Rank x8 Memory Organization

The dual rank x8 configuration is an important aspect of this memory category. Dual rank memory modules contain two sets of memory ranks, which can be accessed independently by the memory controller. This organization enhances memory interleaving and improves overall throughput, particularly in multi-threaded and multi-core processing environments.

Improved Memory Interleaving

By alternating access between ranks, the memory controller can reduce idle cycles and increase effective bandwidth. Dual rank DDR5 ECC UDIMM memory modules are especially beneficial in systems with high core counts, where concurrent memory access demands are common. This leads to better utilization of available bandwidth and smoother performance under load.

288-Pin UDIMM Form Factor

The 288-pin UDIMM form factor is the standard physical interface for DDR5 desktop, workstation, and server memory. This design ensures mechanical compatibility with DDR5 memory slots while preventing accidental installation in incompatible DDR4 or earlier sockets. The physical layout also supports improved signal integrity and higher operating frequencies.

Comparisons with DDR4 Modules

Compared to DDR4, the MTC20C2085S1EC56BA1R DDR5 module offers higher bandwidth, improved power efficiency, and enhanced memory reliability. DDR5 modules support larger capacities per stick, more sophisticated ECC integration, and better handling of simultaneous data streams. Users upgrading from DDR4 can expect measurable improvements in multitasking, application load times, and system responsiveness. In server deployments, DDR5’s higher data rate and on-die ECC result in greater uptime and reduced risk of data corruption compared to legacy DDR4 modules.

Compatibility with Standard Cooling Solutions

The low-profile UDIMM design is compatible with standard server and workstation cooling configurations. This allows for efficient airflow and simplifies system design without the need for specialized memory cooling hardware.
