Overview of Samsung M393A4K40BB1CRC DDR4  PC4-19200 ECC

The Samsung M393A4K40BB1CRC 32GB DDR4 2400MT/s PC4-19200 DDR4 SDRAM 288-Pin RDIMM Memory belongs to a high-performance enterprise server memory category optimized for stability, reliability, and scalability. This category focuses on DDR4 Registered DIMM (RDIMM) technology, designed for professional computing environments such as data centers, virtualization platforms, high-density servers, and mission-critical workloads. Memory modules in this category are engineered to maintain consistent performance under continuous operation, providing predictable latency, efficient power usage, and system-wide compatibility.

DDR4 2400MT/s Performance and PC4-19200 Bandwidth

This memory category operates at 2400 megatransfers per second, corresponding to a PC4-19200 bandwidth rating. This level of performance enables efficient communication between the CPU and memory subsystem, supporting multi-core processors and high-density memory configurations. The Samsung M393A4K40BB1CRC provides a balanced combination of speed and stability, making it ideal for enterprise workloads where consistent data throughput is critical.

CAS Latency and Timing Characteristics

The Samsung M393A4K40BB1CRC features a carefully calibrated CAS latency profile optimized for reliable operation. While high-speed memory modules often push lower latency boundaries, this enterprise category prioritizes predictable timing and signal integrity over marginal latency improvements. Stable latency is essential for applications requiring deterministic memory access patterns, including large-scale virtualization, financial processing, and scientific computing. By maintaining standardized timing parameters, this DDR4 RDIMM category ensures compatibility across different server platforms and CPU architectures.

Registered DIMM Architecture and System Stability

RDIMM memory in this category integrates a register between the memory controller and DRAM chips, buffering command and address signals to reduce electrical load. This architectural approach enables servers to support more memory modules per channel, higher total capacity, and increased stability under heavy workloads. The Samsung M393A4K40BB1CRC RDIMM exemplifies the reliability benefits of registered memory in professional-grade server configurations.

Electrical in Multi-DIMM Systems

In multi-socket, multi-channel server platforms, unbuffered memory can struggle to maintain signal integrity when multiple modules are installed. The RDIMM architecture in this category mitigates such issues by isolating electrical signals and preventing degradation across the memory bus. This results in improved system reliability and reduced risk of memory-related errors, even in high-density configurations.

Enterprise Server Platforms

Memory modules in this category are validated for broad compatibility with enterprise-grade servers from OEMs such as Dell, HPE, Lenovo, and Supermicro. The Samsung M393A4K40BB1CRC ensures predictable operation when deployed in certified configurations, reducing downtime and simplifying server expansion projects. Registered memory also supports advanced platform features such as multi-channel memory interleaving and error detection, providing additional performance and reliability benefits.

Data Integrity Mechanisms

While the Samsung M393A4K40BB1CRC RDIMM does not incorporate ECC, this category of memory is often deployed in conjunction with ECC-enabled server platforms to ensure data integrity. Error correction mechanisms detect and correct single-bit memory errors, protecting sensitive workloads and reducing the likelihood of system instability caused by memory faults. Enterprise DDR4 RDIMM memory is often paired with ECC-capable memory controllers to enhance overall reliability.

Mitigating Risks in Mission-Critical Applications

Even in environments without built-in ECC, RDIMM memory contributes to system reliability by providing electrical stability and controlled timing characteristics. This reduces the risk of memory-related failures, particularly in high-density, multi-DIMM configurations. Organizations relying on server memory for mission-critical applications, such as financial processing, healthcare systems, and scientific research, benefit from this inherent stability.

32GB Module Density and Capacity Planning
