Overview of Samsung M393A4K40CB1-CRC DDR4 SDRAM ECC

The Samsung M393A4K40CB1-CRC 32GB DDR4 PC4-19200 ECC Registered RAM belongs to a specialized category of enterprise-grade server memory engineered for stability, scalability, and long-term operational reliability. This category focuses on DDR4 registered dual in-line memory modules designed to support modern server architectures where electrical integrity, signal timing accuracy, and data consistency are non-negotiable requirements. Registered memory modules introduce a register between the memory controller and the DRAM chips, significantly reducing signal load and enabling servers to support higher memory densities across multiple populated slots.

Positioning Within Server Memory Ecosystems

This memory module sits firmly within the registered DIMM subcategory, commonly abbreviated as RDIMM, which is widely adopted in rack servers, tower servers, blade systems, and enterprise workstations. RDIMMs are favored over unbuffered DIMMs in professional systems due to their ability to maintain signal stability when multiple modules are installed per memory channel. The Samsung M393A4K40CB1-CRC supports this design philosophy by enabling higher total system memory capacities without sacrificing reliability or timing accuracy.

32GB Capacity for High-Density Workloads

The 32GB capacity of the Samsung M393A4K40CB1-CRC places it within a high-density memory category that is essential for contemporary enterprise computing. This capacity allows servers to host large datasets, support numerous virtual machines, and run complex applications without excessive reliance on disk-based swapping. High-capacity memory modules reduce latency by keeping more data resident in system memory, directly improving application responsiveness and throughput.

Impact on Consolidation

Virtualization platforms depend heavily on available system memory to allocate resources to virtual machines and containers. The Samsung M393A4K40CB1-CRC enables higher VM density per host by providing ample memory capacity within each DIMM slot. This supports consolidation strategies where organizations reduce physical server counts while maintaining or expanding compute capacity. Memory-intensive workloads such as virtual desktop infrastructure, ERP systems, and multi-tenant application hosting benefit from larger memory pools. By reducing memory contention and overcommitment, this category of 32GB ECC registered memory contributes to stable performance and predictable behavior across virtualized environments.

DDR4 PC4-19200 Performance Specification

The PC4-19200 classification indicates a peak theoretical bandwidth of 19.2 gigabytes per second, achieved at an effective data rate of 2400MT/s. This performance level aligns with a broad range of enterprise server platforms that prioritize stability and compatibility alongside throughput. DDR4 technology introduces improvements such as higher bank group counts and increased burst lengths, allowing more efficient data transfers compared to previous DDR3 standards. Operating at 2400MT/s, the Samsung M393A4K40CB1-CRC delivers balanced performance suitable for general-purpose and specialized workloads alike.

CAS Latency CL17 Characteristics

The CL17 latency rating defines the number of clock cycles required between a read command and data availability. In enterprise memory design, latency is optimized in conjunction with stability and error correction rather than minimized at the expense of reliability. The CL17 specification of this module complements its 2400MT/s data rate, ensuring consistent response times under sustained multi-threaded workloads. Latency consistency is particularly important for transactional databases, directory services, and application servers where unpredictable memory response times can cascade into broader performance issues.

ECC Technology for Data Integrity Assurance

Error Correcting Code functionality is a defining feature of the Samsung M393A4K40CB1-CRC and a core characteristic of this memory category. ECC memory detects and corrects single-bit errors in real time, preventing data corruption that could otherwise lead to system instability or incorrect computational results. In professional environments where data accuracy is critical, ECC memory is an essential safeguard. Memory errors can occur due to electrical interference, cosmic radiation, or component aging. ECC technology mitigates these risks by ensuring that transient errors do not propagate into applications or stored data. This capability is particularly important in long-running processes, scientific computing, financial systems, and enterprise databases.

Registered Buffering and ECC Synergy

The combination of registered buffering and ECC creates a robust memory solution designed for enterprise reliability. The register reduces electrical load on the memory controller, while ECC ensures data correctness. Together, these features enable servers to operate with large memory configurations across multiple channels and slots without compromising stability. This synergy is especially valuable in high-availability systems where downtime or data corruption can have significant operational and financial consequences. The Samsung M393A4K40CB1-CRC exemplifies this category by integrating both technologies into a single, enterprise-validated module.

288-Pin RDIMM Physical and Electrical Standard

The 288-pin RDIMM form factor is the standardized physical interface for DDR4 registered memory modules. This form factor ensures mechanical compatibility with enterprise server motherboards designed for DDR4 memory. The pin layout supports higher data rates and improved signaling compared to earlier memory generations, contributing to overall system stability. RDIMM modules are electrically distinct from unbuffered DIMMs and load-reduced DIMMs, making it essential to select memory that matches platform requirements. The Samsung M393A4K40CB1-CRC adheres strictly to JEDEC specifications, ensuring compatibility with supported server platforms and firmware configurations.

Multi-Channel Memory Architecture

Modern server CPUs utilize multi-channel memory architectures to maximize bandwidth and parallelism. This category of DDR4 RDIMM memory is designed to operate efficiently in such configurations, allowing balanced population across channels. Proper channel population improves throughput and reduces latency, benefiting workloads that perform frequent memory access operations. The use of registered memory enables full utilization of available memory channels even when all slots are populated, a scenario that would otherwise stress the memory controller if unbuffered modules were used.

Benefits for Data Center Operations

In data center environments, cumulative power savings from efficient memory modules contribute to lower cooling requirements and improved energy utilization metrics. The Samsung M393A4K40CB1-CRC supports these goals by delivering high capacity and reliability without excessive power draw. This aligns with modern data center design principles focused on efficiency, sustainability, and scalability.
