Overview of Samsung M393A4K40CB1-CRC4Q DDR4 PC4-19200

The Samsung M393A4K40CB1-CRC4Q 32GB DDR4 2400MT/s PC4-19200 CL17 ECC Registered SDRAM 288-Pin RDIMM Memory Module belongs to a specialized enterprise memory category designed to meet the rigorous demands of professional server and workstation platforms. This category encompasses DDR4 registered memory modules that emphasize long-term reliability, electrical stability, and data integrity rather than consumer-focused performance metrics. Systems operating within this category are typically deployed in data centers, enterprise IT environments, private and hybrid cloud infrastructures, and mission-critical computing scenarios where uninterrupted operation and accuracy are mandatory.

DDR4 Registered Memory Architecture Principles

The registered memory architecture used in this category introduces a register between the memory controller and the DRAM chips. This register buffers command and address signals, significantly reducing the electrical load placed on the memory controller. By stabilizing signal transmission, registered DIMMs enable servers to support more memory modules per channel and higher total memory capacities without encountering timing instability or signal degradation. In the Samsung M393A4K40CB1-CRC4Q, this architecture is implemented in compliance with JEDEC standards, ensuring interoperability with enterprise server motherboards and chipsets.

32GB Memory Density as a Core Enterprise Requirement

The 32GB capacity of the Samsung M393A4K40CB1-CRC4Q positions it within a high-density memory subcategory that has become essential for contemporary enterprise workloads. As applications grow in complexity and datasets expand, memory capacity has emerged as a primary determinant of system performance and efficiency. High-capacity RDIMM modules allow organizations to scale memory resources without proportionally increasing the number of physical components. This capacity level is especially beneficial in environments that prioritize virtualization, containerization, and in-memory computing.

Influence on Server Consolidation

Virtualization platforms rely heavily on available memory to allocate resources to virtual machines and containers. The Samsung M393A4K40CB1-CRC4Q enables higher consolidation ratios by providing substantial memory capacity within each RDIMM slot. This allows hypervisors to allocate dedicated memory to multiple workloads while minimizing contention and overcommitment. Server consolidation strategies benefit directly from this memory category, as fewer physical systems are required to support the same workload footprint. Reduced hardware sprawl simplifies management, lowers energy consumption, and improves overall data center.

DDR4 2400MT/s PC4-19200 Performance Characteristics

Operating at an effective data rate of 2400MT/s, the Samsung M393A4K40CB1-CRC4Q conforms to the PC4-19200 specification, delivering a theoretical peak bandwidth of 19.2GB/s per module. This performance level reflects a balance between throughput, stability, and broad platform support. DDR4 2400MT/s memory is widely supported across enterprise-grade processors and chipsets, making it a practical and versatile choice for system builders and IT administrators. DDR4 technology introduces several architectural improvements over previous generations, including increased bank group counts and enhanced prefetch mechanisms.

CAS Latency CL17 and Timing Consistency

The CL17 CAS latency rating defines the number of clock cycles required to access data after a read command is issued. In enterprise memory categories, latency specifications are selected to ensure timing stability rather than aggressive optimization. The CL17 timing of this module is carefully matched to its 2400MT/s operating speed, ensuring predictable response times under sustained load. Timing consistency is critical in enterprise environments where multiple applications and services compete for memory access. The Samsung M393A4K40CB1-CRC4Q provides stable latency behavior that supports transactional databases, application servers, and middleware platforms without introducing variability that could impact service-level objectives.

ECC Technology and Data Protection

Error Correcting Code functionality is a defining characteristic of this memory category and a key reason for its adoption in enterprise systems. ECC memory detects and corrects single-bit errors in real time while identifying multi-bit errors that could compromise data integrity. The Samsung M393A4K40CB1-CRC4Q integrates ECC at the hardware level, providing continuous protection against memory-related data corruption. Memory errors can arise from a variety of sources, including electrical noise, environmental factors, and natural radiation effects. In systems that operate continuously and process critical data, even a single uncorrected error can lead to incorrect results or system instability.

Synergy Between ECC and Registered Buffering

The combination of ECC and registered buffering creates a robust memory solution optimized for enterprise reliability. Registered buffering ensures stable electrical signaling, while ECC maintains data correctness. Together, these technologies allow servers to scale memory capacity confidently without increasing the risk of errors or instability. This synergy is particularly valuable in high-availability systems where downtime or data corruption can have severe consequences. The Samsung M393A4K40CB1-CRC4Q embodies this approach, delivering a memory solution that supports large configurations and continuous operation.

288-Pin RDIMM Physical Interface and Standards

The 288-pin RDIMM form factor is the standardized physical interface for DDR4 registered memory modules. This form factor supports higher signaling frequencies and improved electrical characteristics compared to earlier memory generations. The Samsung M393A4K40CB1-CRC4Q adheres strictly to JEDEC specifications, ensuring compatibility with enterprise server motherboards designed for DDR4 RDIMM memory. RDIMM modules are electrically distinct from unbuffered DIMMs and load-reduced DIMMs, making correct selection essential for system compatibility. This category is specifically intended for platforms that support registered memory, ensuring optimal performance and stability when deployed in supported environments.

Multi-Channel and Multi-Socket Architectures

Modern enterprise processors utilize multi-channel memory controllers to maximize bandwidth and parallelism. The Samsung M393A4K40CB1-CRC4Q is designed to operate efficiently within these architectures, enabling balanced memory channel population. Proper channel population enhances throughput and reduces contention, benefiting workloads that rely on frequent memory access. In multi-socket systems, registered memory ensures consistent signaling across CPUs, supporting scalable configurations that maintain performance as memory capacity increases. This capability is essential for large enterprise servers and compute nodes.

Thermal Stability

Operating at a nominal voltage of 1.2V, the Samsung M393A4K40CB1-CRC4Q benefits from the power efficiency improvements inherent to DDR4 technology. Lower voltage operation reduces overall power consumption and heat generation, which are critical considerations in dense server environments where thermal management directly impacts reliability and cost. Thermal stability is essential for maintaining consistent memory performance under sustained workloads. Samsung’s manufacturing processes emphasize uniform electrical and thermal characteristics, ensuring that modules perform reliably across typical data center temperature ranges.

Operational Data Center Deployments

In large-scale deployments, incremental improvements in memory power efficiency can yield significant cumulative savings. The Samsung M393A4K40CB1-CRC4Q contributes to reduced cooling requirements and improved energy utilization metrics, supporting modern data center efficiency initiatives and sustainability goals.
