Overview of Samsung M393A4K40CB1-CRC4Q DDR4 2400MT/s

The Samsung M393A4K40CB1-CRC4Q 32GB DDR4 2400MT/s PC4-19200 ECC Registered RDIMM Memory Module is positioned within a specialized enterprise memory category designed for professional server and workstation environments. This category focuses on DDR4 registered memory modules that combine high-density capacity, electrical signal buffering, and advanced error correction to meet the demands of modern data-driven infrastructures. Such memory modules are engineered to operate continuously under heavy workloads while maintaining strict data integrity and platform stability.

Registered DIMM Architecture and Signal Integrity

The registered DIMM architecture employed by this memory module introduces a register between the memory controller and the DRAM chips. This register buffers command and address signals, reducing electrical load and improving signal integrity across memory channels. In enterprise systems with multiple DIMMs installed per channel, this architectural approach ensures stable operation even at higher memory densities. Within this category, registered memory enables scalable configurations that would otherwise challenge the limits of unbuffered memory.

32GB High-Density Memory Capacity for Enterprise Workloads

The 32GB capacity of the Samsung M393A4K40CB1-CRC4Q places it firmly within the high-density memory segment, a crucial category for modern enterprise computing. As applications grow more data-intensive and virtualization becomes more pervasive, memory capacity directly influences system efficiency and performance. High-capacity RDIMM modules allow organizations to maximize memory per server while minimizing slot consumption. This memory capacity supports large datasets, in-memory processing, and high virtual machine densities. By keeping more active data resident in memory, systems can reduce latency associated with disk access and improve overall workload responsiveness.

Role in Resource

Virtualized infrastructures 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 per DIMM slot. This allows hypervisors to allocate sufficient memory to each virtual instance while maintaining isolation and performance consistency. Resource optimization achieved through higher memory density reduces hardware sprawl and simplifies management. Fewer physical servers can support the same workload footprint, lowering operational costs and improving energy efficiency across the data center.

DDR4 2400MT/s PC4-19200 Performance Profile

Operating at an effective data rate of 2400MT/s, this memory module conforms to the PC4-19200 specification, delivering up to 19.2GB/s of theoretical bandwidth per module. This performance profile is widely supported across enterprise server platforms and represents a balanced approach to throughput, stability, and power efficiency. DDR4 technology introduces architectural improvements such as increased bank groups and enhanced prefetch mechanisms, enabling more efficient data access patterns. The Samsung M393A4K40CB1-CRC4Q leverages these enhancements to provide consistent performance under multi-threaded and multi-user workloads typical of enterprise environments.

CAS Latency CL17 and Timing Stability

The CL17 CAS latency rating reflects the module’s timing characteristics, optimized for reliable operation at 2400MT/s. In enterprise memory categories, timing stability is prioritized over aggressive low-latency tuning to ensure predictable behavior under sustained load. The CL17 specification ensures balanced read and write operations without compromising reliability. Consistent latency is essential for workloads such as transactional databases, directory services, and application servers where timing variations can impact response times. This memory module delivers stable timing behavior aligned with enterprise performance expectations.

ECC Technology for Data Accuracy

Error Correcting Code functionality is a defining feature of the Samsung M393A4K40CB1-CRC4Q and a cornerstone of this memory category. ECC technology detects and corrects single-bit memory errors in real time, preventing data corruption that could otherwise compromise applications or system stability. In mission-critical environments, ECC memory is essential to maintaining data accuracy and operational integrity. Memory errors can result from various factors, including electrical noise, environmental conditions, and component aging. ECC mitigates these risks by ensuring that transient errors do not propagate into software layers.

ECC and Registered Buffering Integration

The integration of ECC with registered buffering enhances overall memory reliability. Registered buffering stabilizes electrical signaling, while ECC ensures data correctness. Together, these features allow enterprise servers to operate with large memory footprints without sacrificing stability. This integration is critical in high-availability systems where memory-related faults could lead to downtime or data loss. The Samsung M393A4K40CB1-CRC4Q exemplifies this category by combining both technologies in a single, enterprise-validated module.

288-Pin RDIMM Form Factor and Platform

The 288-pin RDIMM form factor is the standardized physical interface for DDR4 registered memory modules. This form factor ensures compatibility with enterprise server motherboards designed to support DDR4 RDIMM configurations. The pin layout supports higher signaling frequencies and improved electrical characteristics compared to earlier memory generations. RDIMM modules are electrically distinct from unbuffered and load-reduced DIMMs, making correct selection essential for system compatibility. The Samsung M393A4K40CB1-CRC4Q adheres to JEDEC standards, ensuring seamless integration with supported platforms and firmware configurations.

Multi-Channel and Multi-Socket Server

Modern server architectures employ multi-channel memory controllers to maximize bandwidth and parallelism. This category of DDR4 RDIMM memory is designed to operate efficiently within such architectures, enabling balanced population across channels. Proper channel population enhances throughput and reduces contention, benefiting memory-intensive workloads. In multi-socket systems, registered memory ensures consistent performance across CPUs, supporting scalable configurations that maintain stability as memory capacity increases.

Long-Term Reliability

Operating at a nominal voltage of 1.2V, the Samsung M393A4K40CB1-CRC4Q benefits from the power efficiency improvements inherent to DDR4 technology. Lower operating voltage reduces overall power consumption and heat generation, which is critical in dense server environments where thermal management is a constant challenge. Efficient thermal behavior ensures that memory performance remains stable under sustained workloads. Samsung’s manufacturing processes emphasize uniform electrical and thermal characteristics, reducing the risk of hotspots and ensuring long-term reliability.

Data Center Considerations

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