Product Description
This Samsung M393A8K40B21-CTC4Q module is a high-capacity 64GB DDR4 Registered DIMM (RDIMM), engineered to meet the extreme memory demands of modern enterprise servers and data centers. DDR4 technology provides superior bandwidth and power efficiency compared to previous generations, making it the foundation for high-performance computing. The RDIMM architecture includes an onboard register that buffers command and address signals, significantly reducing the electrical load on the memory controller and enabling greater memory scalability and system stability, especially in systems configured with numerous memory modules. The 4Rx4 organization signifies a quad-rank module, where each rank uses a x4 data width. This multi-rank design allows for enhanced memory interleaving by the system's memory controller, which can lead to improved performance in memory-intensive workloads. The 2400MHz speed (PC4-19200) delivers substantial data throughput, essential for applications such as large-scale virtualization, in-memory databases, scientific simulations, and complex data analytics. The CL17 CAS Latency is standard for DDR4 modules at this frequency, balancing speed with power efficiency. This 64GB RDIMM is specifically designed for environments that require the utmost in memory capacity and reliability. It is an ideal choice for upgrading servers to support massive datasets, consolidating virtual machines, or powering demanding computational tasks. The module operates at a standard 1.2V, contributing to energy efficiency in high-density server deployments. Its robust specifications ensure compatibility and high performance within compatible server platforms.
