Overview of Samsung M393A4K40BB1-CRC 2400MT/s PC4-19200

The Samsung M393A4K40BB1-CRC 32GB DDR4 2400MT/s PC4-19200 DDR4 SDRAM CL17 288-Pin RDIMM ECC Registered Memory represents a premium enterprise memory category engineered for high-performance server and workstation environments. This category emphasizes reliability, stability, and scalability, combining DDR4 RDIMM architecture with ECC functionality to ensure superior data integrity and predictable operation under intensive workloads. Memory modules in this category are designed to meet the stringent requirements of data centers, virtualization platforms, cloud infrastructures, mission-critical applications, and high-performance computing environments.

DDR4 2400MT/s Speed and PC4-19200 Bandwidth Performance

This memory category operates at 2400 megatransfers per second, delivering PC4-19200 bandwidth and providing a theoretical peak of 19.2 GB/s per module. This speed tier allows for fast data transfer between the CPU and memory subsystem, which is critical for enterprise workloads that require sustained throughput rather than short-term peak performance. The Samsung M393A4K40BB1-CRC ensures consistent memory access and minimizes latency fluctuations in high-demand server environments.

CL17 Latency and Timing Reliability

CAS latency (CL17) in this category is optimized for enterprise stability and predictability rather than aggressive low-latency performance. This ensures that each memory access occurs within a deterministic timeframe, essential for applications where consistent timing is critical, such as transactional databases, financial systems, virtualized environments, and mission-critical workloads. The Samsung M393A4K40BB1-CRC maintains uniform latency across multiple modules and channels, ensuring system-wide consistency.

RDIMM Architecture and Enterprise System Stability

Registered DIMM (RDIMM) architecture is a hallmark of this memory category. RDIMMs include a register that buffers address and command signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, enabling higher memory densities and improved signal integrity across multi-DIMM configurations. The Samsung M393A4K40BB1-CRC demonstrates the benefits of RDIMM design, including enhanced system stability, scalability, and reliability in high-performance server environments.

Electrical Multi-DIMM Systems

Servers equipped with multiple DIMMs per channel often experience signal degradation and potential instability with unbuffered memory. RDIMM architecture addresses these challenges by isolating and buffering electrical signals, preserving signal integrity across all installed modules. This design is particularly critical in multi-socket server configurations, high-density virtualization hosts, and enterprise blade or rack-mounted servers where stable memory operation is essential for uninterrupted service.

ECC Functionality and Data Integrity

ECC (Error-Correcting Code) functionality is central to this memory category. ECC provides real-time detection and correction of single-bit errors and the detection of multi-bit errors, significantly enhancing system stability and reducing the risk of data corruption. The Samsung M393A4K40BB1-CRC leverages ECC to ensure the integrity of critical workloads, making it suitable for applications in finance, healthcare, scientific computing, virtualization, and high-availability enterprise servers.

Mitigating Memory-Induced Errors and Failures

Memory errors can occur due to electrical noise, cosmic rays, voltage fluctuations, or hardware degradation over time. Without ECC, these errors may lead to silent data corruption or unexpected system crashes. This category mitigates such risks through built-in ECC functionality, ensuring that mission-critical applications operate without interruption and reducing unplanned downtime associated with memory-related failures.

Enhanced Reliability for Continuous Operation

Servers in enterprise environments often operate continuously, 24/7. ECC memory provides a layer of protection that supports uninterrupted operation and ensures data integrity over long periods. The Samsung M393A4K40BB1-CRC RDIMM ECC offers consistent error detection and correction, providing peace of mind for IT administrators managing high-density data centers, virtualization clusters, or cloud infrastructures.

32GB Module Capacity and Enterprise Scalability

The 32GB module capacity in this category strikes a balance between high memory density and efficient resource utilization. High-capacity modules enable large total memory configurations while occupying fewer DIMM slots, improving airflow, reducing energy consumption per gigabyte, and optimizing server layout. The Samsung M393A4K40BB1-CRC supports scalable enterprise deployments where both performance and capacity are critical factors.

Scalable Cloud Deployments

Virtualized environments and cloud infrastructure benefit from high-density memory modules, which allow for larger virtual machine allocations and higher consolidation ratios. IT administrators can expand memory incrementally with 32GB RDIMM modules, scaling infrastructure without replacing existing hardware. This category ensures cost-effective scalability and efficient resource allocation across enterprise servers.

288-Pin RDIMM Form Factor and Mechanical

The 288-pin RDIMM form factor ensures both mechanical and electrical compatibility with enterprise server motherboards. This standard provides secure installation, precise pin alignment, and predictable signal transmission across multi-DIMM configurations. Enterprise servers, including tower, rack-mounted, and blade systems, rely on this form factor to maintain consistent memory performance and reliable operation across multiple modules and channels.

Platform Certification

Memory modules in this category are certified by OEMs for compatibility and reliability with their server platforms. The Samsung M393A4K40BB1-CRC RDIMM ECC meets these standards, offering predictable performance in high-density or multi-node deployments. Certified memory simplifies maintenance, reduces the risk of unsupported configurations, and ensures long-term operational stability in enterprise data centers.

Continuous 24/7 Operation

Enterprise servers operate continuously, often under full load, making thermal efficiency and electrical stability critical. This memory category provides consistent performance under sustained workloads, minimizing thermal-related performance degradation. The Samsung M393A4K40BB1-CRC is designed for long-term stability in high-density, high-performance servers and cloud computing clusters.
