This category emphasizes stability, reliability, and scalability, combining DDR4 technology with RDIMM (Registered DIMM) architecture and ECC (Error-Correcting Code) functionality. It is engineered to meet the rigorous demands of modern data centers, virtualization infrastructures, cloud platforms, and high-performance computing clusters where data integrity, low latency, and high throughput are essential.

DDR4 2400MT/s Speed and Bandwidth Performance

This category of memory operates at a transfer rate of 2400 megatransfers per second, delivering a theoretical peak bandwidth of 19.2GB/s per module. Such performance ensures rapid communication between the CPU and memory subsystem, which is critical for enterprise workloads requiring high throughput and consistent performance. The Samsung M393A4K40BB1-CRC40 provides reliable data transfer for sustained workloads, enabling multi-core server processors to efficiently manage memory-intensive applications.

CL17 Latency and Timing Stability

CAS latency of CL17 ensures that memory accesses occur in a deterministic manner, which is critical for enterprise environments where predictability and stability are more important than extreme low-latency performance. This timing profile supports mission-critical applications such as ERP systems, financial platforms, and cloud infrastructure where consistent access speeds are necessary. The Samsung M393A4K40BB1-CRC40 maintains stable timing across multiple DIMM modules and channels, ensuring uniform memory behavior under sustained load.

RDIMM Architecture and Enterprise Reliability

Registered DIMMs (RDIMMs) feature a register between the memory controller and the DRAM chips, which buffers address and command signals. This reduces electrical load on the memory controller, enabling higher memory density and enhanced signal integrity in multi-DIMM configurations. The Samsung M393A4K40BB1-CRC40 demonstrates the advantages of RDIMM design, including increased system stability, reliability, and scalability in high-density server environments.

Electrical Signal Integrity in Multi-DIMM Systems

In multi-channel, multi-socket server platforms, unbuffered memory modules can experience signal degradation, leading to instability and errors. RDIMM architecture mitigates this issue by isolating and buffering signals, maintaining electrical integrity across all installed modules. This is particularly important in enterprise-grade servers, blade systems, and dense virtualization environments where stable memory operation is crucial for uninterrupted service.

OEM Platform Certification

Memory modules in this category undergo rigorous testing and certification to ensure compatibility with enterprise server platforms from leading OEMs, including Dell, HPE, Lenovo, and Supermicro.
