This category is defined by the use of DDR4 registered dual in-line memory modules combined with error-correcting code functionality, enabling servers to operate continuously under demanding workloads while maintaining data integrity. Memory within this category is designed not as a performance burst component, but as a foundational infrastructure element that supports sustained, mission-critical operations.

Registered DIMM Architecture Signal

Registered DIMMs are a defining attribute of this category, providing critical signal buffering between the memory controller and DRAM components. The integrated register reduces electrical load on the processor’s memory controller, enabling stable operation even when multiple high-capacity modules are installed per memory channel. This architectural feature allows servers to scale memory capacity without sacrificing reliability or timing accuracy. The Samsung M393A4K40BB1-CRC4Q module adheres to JEDEC RDIMM specifications, ensuring consistent signal behavior across supported platforms.

Load Reduction and Channel Scalability

By buffering address and command signals, RDIMM memory minimizes signal reflections and noise. This characteristic is particularly valuable in multi-socket servers where memory traces are longer and more complex. The category supports higher total system memory capacities while maintaining stable operating conditions.

DDR4 SDRAM Technology and PC4-19200 Characteristics

DDR4 SDRAM technology underpins this memory category, delivering improved efficiency and higher achievable densities compared to previous generations. Operating at 2400MT/s, the Samsung M393A4K40BB1-CRC4Q provides PC4-19200 bandwidth, which remains a widely supported speed grade across enterprise platforms. This frequency tier offers an optimal balance between throughput, compatibility, and power efficiency, making it a preferred choice for long-term server deployments. This category focuses on sustained, real-world performance rather than peak theoretical metrics. DDR4 2400MT/s memory has been extensively validated across server ecosystems, ensuring predictable behavior under continuous load conditions.

CAS Latency CL17 and Timing Stability

The CL17 timing specification associated with this category reflects a conservative and stable latency profile. Lower latency consistency is often more important than raw speed in enterprise workloads, where predictable response times support database transactions, virtualization scheduling, and application performance. The Samsung M393A4K40BB1-CRC4Q maintains stable latency characteristics even under heavy memory access patterns. Modern server processors feature high core counts and multiple memory channels.
