Overview of Samsung M386A8K40BM1-CRC4Q PC4-19200 SDRAM

The Samsung M386A4K40BB0-CRC 32GB DDR4 2400MBPS PC4-19200 ECC Registered LRDIMM memory module represents a specialized category of enterprise server memory designed for sustained performance, operational stability, and large-scale system scalability. This category focuses on load-reduced dual in-line memory modules engineered specifically for modern data center environments where high memory density, reduced electrical load, and data accuracy are critical requirements. Unlike consumer-grade memory, DDR4 LRDIMM modules are built to meet the demands of mission-critical computing infrastructures that operate continuously under heavy workloads.

DDR4 SDRAM Technology and Performance Characteristics

DDR4 SDRAM technology defines a major advancement in server memory architecture, delivering higher data transfer rates and improved power efficiency. The Samsung M386A4K40BB0-CRC operates at 2400MBPS, classified under the PC4-19200 standard, enabling faster access to data-intensive applications. This speed tier ensures balanced performance for multi-threaded workloads, transactional databases, and enterprise applications that rely on consistent memory response times.

ECC Registered Memory Design and Data Integrity

Error-Correcting Code functionality is a defining attribute of this memory category. ECC memory continuously monitors and corrects single-bit data errors, significantly reducing the risk of system crashes, corrupted data, or unexpected downtime. In enterprise environments where data accuracy is non-negotiable, ECC Registered memory provides a layer of protection that standard non-ECC modules cannot offer. The registered signal processing design further enhances system stability by reducing electrical load on the memory controller.

Load Reduced DIMM Technology and Scalability

Load Reduced DIMM architecture plays a critical role in enabling high-capacity server configurations. By reducing the electrical burden on the memory controller, LRDIMM modules allow more memory modules to be installed per channel compared to RDIMM solutions. This category is optimized for systems that require maximum memory density while maintaining consistent performance levels. The Samsung M386A4K40BB0-CRC leverages LRDIMM technology to support scalable memory architectures in enterprise servers. This enables organizations to expand memory resources incrementally as workload demands increase, extending the lifecycle of server platforms and improving return on investment.

Memory Capacity for Enterprise Workloads

The 32GB capacity of this DDR4 LRDIMM module aligns with the requirements of modern enterprise workloads that demand both high capacity and performance. Memory-intensive applications such as virtualization hosts, enterprise resource planning systems, and cloud-native platforms benefit from larger memory pools that reduce reliance on slower storage-based caching mechanisms. This category is particularly relevant for environments where multiple virtual machines or containers operate concurrently. Adequate memory allocation ensures smoother workload distribution, improved application responsiveness, and reduced latency under peak load conditions.

Latency and Timing Considerations

With a CAS latency rating of CL40, this memory module is optimized for stable enterprise performance rather than consumer-grade low-latency benchmarks. In server environments, predictable latency and sustained throughput are more valuable than minimal access times. The timing profile of this category supports balanced performance across diverse workloads without introducing instability. Latency characteristics are carefully calibrated to align with registered memory buffering and ECC processing, ensuring data accuracy while maintaining acceptable response times. This balance is critical for enterprise systems that prioritize uptime and data consistency over raw speed metrics.

Rank Configuration

The 2Rx4 rank structure of the Samsung M386A4K40BB0-CRC enhances memory efficiency by distributing data access across multiple ranks. This design improves memory interleaving and contributes to better overall system performance under parallel workloads. Rank optimization is a key factor in achieving consistent throughput in multi-processor server architectures. By leveraging x4 DRAM components, this memory category supports advanced error correction mechanisms while maintaining compatibility with enterprise-class memory controllers. The rank configuration is engineered to meet strict server qualification standards, ensuring seamless integration with supported platforms.

Virtualization platforms rely heavily on memory capacity and reliability to maintain performance across multiple workloads. The Samsung M386A4K40BB0-CRC category supports memory-intensive virtualization scenarios by providing stable, error-corrected memory that can be allocated dynamically to virtual machines. Cloud infrastructure providers benefit from the scalability and density offered by LRDIMM memory, enabling higher consolidation ratios and more efficient resource utilization. This category supports the foundational memory requirements of private, hybrid, and public cloud deployments.

Database and Analytics Workload

Enterprise databases and analytics platforms require large memory pools to deliver fast query performance and real-time data processing. This memory category supports in-memory computing architectures that reduce disk I/O and improve transaction throughput. ECC protection ensures data integrity during intensive read and write operations. Analytics workloads benefit from consistent memory bandwidth and predictable latency, enabling faster data aggregation and reporting. The PC4-19200 speed tier provides sufficient bandwidth for most enterprise analytics use cases without sacrificing stability.
