The Micron MTC40F2046S1RC64BH1 64GB PC5-51200 Memory

The Micron MTC40F2046S1RC64BH1 64GB DDR5 RDIMM memory module belongs to a high-performance enterprise memory category designed for modern data centers, virtualization platforms, and mission-critical server environments. This category focuses on registered DDR5 SDRAM modules that deliver exceptional bandwidth, improved power efficiency, and advanced reliability features. DDR5 RDIMM memory represents a significant evolution over previous DDR4 technologies by introducing higher transfer rates, increased density per module, and enhanced signal integrity suitable for multi-socket server architectures.With a capacity of 64GB in a single module, this DDR5 RDIMM category supports memory-intensive workloads such as cloud computing, large database management systems, AI inference, virtualization clusters, and enterprise resource planning platforms. The PC5-51200 rating and 6400MHz data rate ensure faster data throughput, enabling servers to handle more simultaneous operations while reducing latency bottlenecks across CPU and memory subsystems.

High Capacity 64GB Memory

The 64GB module capacity defines a category of high-density server memory designed to support demanding workloads that require substantial memory footprints. Single-module 64GB RDIMM configurations enable flexible scaling, allowing system integrators and IT administrators to populate servers with fewer modules while still achieving large total memory capacities.This category is particularly valuable for virtualization hosts, where multiple virtual machines compete for memory resources, and for database servers that rely on large in-memory datasets to accelerate query performance. High-density DDR5 RDIMM memory also benefits analytics platforms and containerized environments that require predictable performance under heavy load.

DDR5 Technology

DDR5 technology introduces a wide range of architectural improvements that make it ideal for enterprise and server-class systems. Registered DIMM modules incorporate a register (or buffer) between the memory controller and the DRAM chips, improving electrical stability and allowing systems to scale memory capacity without compromising performance. This category of DDR5 RDIMM memory is optimized for reliability, scalability, and continuous operation.

PC5-51200 Bandwidth and 6400MHz Performance

The PC5-51200 classification places this memory module within a high-bandwidth DDR5 category capable of delivering up to 51.2GB/s of theoretical bandwidth per module. Operating at 6400MHz, this category is designed to complement the latest server processors that demand fast and consistent access to memory resources.Higher memory frequencies directly impact application responsiveness, particularly in data-intensive workloads such as real-time analytics, high-performance computing, and large-scale simulations. DDR5 RDIMM modules operating at 6400MHz help minimize memory latency while maximizing throughput, allowing CPUs to remain fully utilized.

Balanced Performance with CL52 Latency

CAS latency plays a critical role in determining real-world memory performance. With a CL52 latency rating, this DDR5 RDIMM category strikes a balance between high frequency and stable operation. While higher frequencies naturally increase latency values, the overall performance gains from increased bandwidth often outweigh raw latency considerations in server environments.Enterprise workloads typically benefit more from sustained throughput and predictable performance than from ultra-low latency alone. As such, CL52 DDR5 RDIMM modules are well suited for workloads that involve large data transfers, memory streaming, and parallel processing.

2Rx4 Memory Configuration

The 2Rx4 configuration refers to a dual-rank module with x4 DRAM chip organization. This category of memory is specifically engineered for servers that require enhanced reliability and memory interleaving capabilities. Dual-rank designs allow the memory controller to access multiple ranks, improving performance through better utilization of available memory banks. x4 SDRAM organization is a key feature in enterprise memory modules, as it enables more robust error detection and correction. This configuration is commonly used in server-grade RDIMM modules to meet strict reliability and availability requirements.

Advantages of Dual-Rank RDIMM Modules

Dual-rank RDIMM memory provides improved memory throughput by allowing the memory controller to alternate between ranks during read and write operations. This reduces idle cycles and enhances overall efficiency, particularly in multi-core server processors.In addition, dual-rank modules can offer better performance scaling in systems populated with fewer DIMMs. This makes them an ideal choice for servers that prioritize both capacity and performance while maintaining compatibility with enterprise-class motherboards.

Latency and Signal Processing

The registered signal processing design reduces electrical load on the memory controller, allowing systems to support larger memory capacities with improved stability. With a CAS latency of CL52, the module maintains predictable response times essential for enterprise-grade computing.

ECC Registered Memory for Data Integrity

Error Correcting Code (ECC) memory is a defining characteristic of enterprise-grade RDIMM categories. ECC functionality enables the detection and correction of single-bit memory errors, significantly reducing the risk of data corruption. In mission-critical environments, data integrity is paramount, making ECC memory an essential requirement.Registered memory further enhances stability by buffering command and address signals. This reduces electrical load on the memory controller and enables systems to support larger memory configurations with improved reliability.

288-Pin RDIMM Form Factor Compatibility

The 288-pin RDIMM form factor defines the physical and electrical interface for DDR5 server memory modules. This category is designed exclusively for server and workstation motherboards that support DDR5 RDIMM slots. The pin layout ensures proper alignment, signal integrity, and compatibility with modern server chipsets.DDR5 RDIMM modules are not interchangeable with unbuffered DIMMs or previous DDR generations, reinforcing their role as specialized components for enterprise systems. Proper compatibility ensures optimal performance and long-term reliability.

Server Platform Integration

This category of DDR5 RDIMM memory integrates seamlessly with next-generation server platforms built around high-core-count CPUs. System architects can deploy these modules in multi-socket servers to achieve balanced memory distribution and maximize overall system performance.The standardized 288-pin design simplifies installation and maintenance, allowing IT teams to upgrade or replace memory modules with minimal disruption.

1.1V Operating Voltage and Power Efficiency

Operating at 1.1V, DDR5 RDIMM memory modules offer improved power efficiency compared to earlier generations. Lower operating voltage reduces overall system power consumption and heat output, which is critical in dense server environments where energy efficiency directly impacts operating costs.This category benefits from on-DIMM power management integrated circuits (PMICs), which provide more precise voltage regulation and contribute to stable operation under varying workloads.

Micron DDR5 vs. Previous Generations

Compared to DDR4 memory, DDR5 provides higher density, increased memory bandwidth, and improved energy efficiency. The MTC40F2046S1RC64BH1 leverages these advancements, delivering better overall performance for servers and high-end computing systems. Features such as on-die ECC, dual-channel DIMM architecture, and enhanced burst length enable more reliable data processing and faster memory access. Additionally, the lower operating voltage of 1.1V reduces heat generation and operational costs, offering a significant advantage over DDR4 modules.

Scalability and Future-Ready Design

DDR5 RDIMM memory modules are engineered with future scalability in mind. Support for higher densities and faster speeds ensures compatibility with upcoming server platforms and processor generations. Investing in this category of memory allows organizations to extend the lifespan of their infrastructure while maintaining competitive performance levels.The modular nature of RDIMM configurations enables incremental upgrades, allowing IT teams to expand memory capacity as workloads evolve without requiring complete system overhauls.
