This category addresses the growing demand for dependable memory solutions in business-critical applications that operate continuously under sustained workloads.

DDR4 SDRAM Architecture and Technological Advancements

DDR4 SDRAM technology introduced significant architectural improvements over previous DDR3 generations, enabling higher bandwidth, lower operating voltage, and improved signal integrity. Within this category, DDR4 UDIMM modules operating at 2400 MT/s provide a balanced combination of speed and efficiency, supporting modern processors that rely on faster memory channels to optimize data throughput. The use of PC4-19200 classification ensures compatibility with platforms designed around standardized DDR4 performance metrics, making these modules suitable for a wide range of enterprise and professional systems.

Memory Bandwidth and Data Transfer Efficiency

A data transfer rate of 2400 MT/s allows DDR4 UDIMM memory modules to deliver sufficient bandwidth for multitasking environments, virtualization workloads, and data-intensive applications. This speed rating supports smoother communication between the CPU and memory subsystem, reducing latency during peak operational loads. In category terms, memory modules with this specification are commonly selected for balanced performance systems that require dependable throughput without excessive power consumption.

Voltage Optimization and Power Efficiency

Operating at a nominal voltage of 1.2V, DDR4 memory in this category significantly reduces power draw compared to earlier DDR3 modules. Lower voltage operation contributes to reduced thermal output, improved energy efficiency, and longer component lifespan. For data centers, offices, and industrial environments where systems may run continuously, this characteristic aligns with energy-conscious infrastructure planning and operational cost control.

Error Correction Code Memory Classification

ECC memory is a defining feature of this category, offering enhanced data reliability through automatic detection and correction of single-bit memory errors. The Samsung M391A2K43BB1-CRC00 exemplifies ECC UDIMM memory designed for systems where data accuracy is non-negotiable. ECC functionality minimizes the risk of silent data corruption, system crashes, and unexpected downtime, making this category particularly relevant for professional workloads.

ECC Unbuffered Memory Functionality

ECC unbuffered DIMMs combine error correction capabilities with a direct electrical connection between the memory controller and the DRAM chips. Unlike registered memory, UDIMM modules do not introduce additional buffering latency, allowing faster response times while still maintaining data integrity. This makes the category ideal for platforms that support ECC but do not require the scalability of registered DIMMs.

Data Integrity in Professional Computing

In environments such as financial systems, engineering workstations, database servers, and content creation platforms, data accuracy is critical. ECC UDIMM memory reduces the likelihood of computational errors caused by electrical interference or cosmic radiation. Category products with ECC support help ensure consistent system behavior, even during extended operational cycles.

Platform Compatibility and Chipset Support

ECC unbuffered memory modules are supported by specific CPU architectures and chipsets, typically found in workstation-class processors and entry-level server platforms. This category is targeted at users who require ECC benefits without transitioning to full server-class registered memory architectures. Compatibility with Intel Xeon E-series, select Core processors with ECC support, and comparable AMD platforms positions this category as a versatile solution.

Module Configuration and Memory Density

The 16GB capacity offered by modules in this category reflects a widely adopted standard for professional systems. This density allows sufficient headroom for modern operating systems, virtualization environments, and demanding applications without overburdening system resources. As memory requirements continue to grow, 16GB DDR4 UDIMM modules remain a foundational building block for scalable configurations.

Dual Rank (2Rx8) Memory Design

Dual rank memory architecture, identified as 2Rx8, plays a significant role in performance optimization. By distributing memory access across two ranks, the memory controller can improve interleaving and throughput efficiency. This configuration enhances performance in multi-threaded workloads and improves responsiveness under concurrent memory access scenarios.

Impact of Rank Structure on Performance

In category applications such as virtualization hosts and professional workstations, dual rank memory can provide measurable performance benefits over single rank alternatives. Improved memory access patterns reduce bottlenecks and contribute to smoother execution of parallel tasks. This makes dual rank ECC UDIMM modules a preferred choice in balanced system designs.

Scalability and Upgrade Flexibility

Modules with 16GB capacity and dual rank design offer flexibility when expanding system memory. Users can populate multiple DIMM slots to reach higher total capacities while maintaining compatibility and stability. This category supports incremental upgrades, allowing organizations to adapt systems to evolving workload demands without complete hardware replacement.

Latency Characteristics and Timing Specifications

CAS latency plays a crucial role in determining memory responsiveness. With a CL17 rating, DDR4-2400 ECC UDIMM modules in this category provide an effective balance between speed and stability. While lower latency is always desirable, CL17 at 2400 MT/s aligns with JEDEC standards, ensuring broad compatibility and predictable performance.

Understanding CAS Latency in Real-World Applications

CAS latency represents the delay between a memory controller request and data availability. In professional environments, consistent latency is often more important than minimal latency. Category memory modules with standardized timing profiles deliver reliable performance across supported platforms, reducing the risk of instability caused by aggressive timing configurations.
