The Samsung M393A4K40BB1-CRC4Q 32GB DDR4 2400MT/s PC4-19200 CL17 ECC Registered 2X4 1.2V SDRAM 288-Pin RDIMM memory module belongs to a high-performance enterprise server memory category, specifically designed to meet the rigorous requirements of modern data centers, virtualization platforms, and mission-critical computing systems. This category emphasizes stability, scalability, and error-correcting capabilities, catering to environments where uninterrupted operation and data integrity are essential.

Registered DIMM (RDIMM) Architecture

Registered DIMM modules are fundamental to this category, providing electrical buffering between the memory controller and DRAM chips. This buffering significantly reduces the electrical load on the memory controller, which allows multiple high-capacity modules to be installed per channel without compromising system stability. RDIMM architecture is particularly beneficial in multi-socket server configurations, where memory signal integrity is critical due to longer trace lengths and denser population.

Signal Integrity and Reliability Enhancements

By incorporating a register between the memory controller and DRAM chips, RDIMM modules improve signal integrity, reduce timing skew, and mitigate electrical noise. This category’s design allows enterprise servers to operate with full memory slot population while maintaining stable latency and throughput. The Samsung M393A4K40BB1-CRC4Q module demonstrates robust electrical design, supporting high-performance server platforms with predictable, repeatable performance.

Electrical Load Distribution

The register in RDIMM modules distributes electrical load across memory channels, reducing the chance of data errors and improving overall system reliability. This is essential for enterprise deployments where continuous uptime is required, such as in cloud infrastructure, virtualization clusters, and high-availability servers.

DDR4 SDRAM Technology and PC4-19200 Classification

DDR4 SDRAM represents the technological foundation of this memory category. With a speed rating of 2400MT/s and a bandwidth of 19.2GB/s (PC4-19200), modules in this category offer reliable and consistent memory throughput. DDR4 technology provides significant improvements over previous generations, including lower operating voltage (1.2V), higher memory densities, and enhanced thermal efficiency. This category prioritizes stable and sustained memory performance over short-term speed spikes. Servers relying on DDR4 2400MT/s modules can handle intensive workloads while maintaining predictable latency.

CAS Latency and Timing Considerations

The Samsung M393A4K40BB1-CRC4Q module operates with a CAS latency of CL17. Within this category, the combination of 2400MT/s speed and CL17 latency provides a balance between bandwidth and response time, ensuring that enterprise workloads maintain consistent performance even under full memory load. The focus on latency stability rather than extreme speed is a hallmark of this category, which values predictable performance in mission-critical systems.

Memory Channel for Multi-Core Servers

Modern servers feature multi-core processors with multiple memory channels. This memory category ensures balanced bandwidth distribution across these channels, reducing contention and enabling efficient data access. Balanced channel usage enhances overall system throughput and optimizes the performance of memory-intensive applications such as enterprise databases, analytics engines, and virtual machine hosting.
