Product Description
This Samsung M393A4K40CB2-CVFB0 module is a high-capacity 32GB DDR4 Registered DIMM (RDIMM), engineered for demanding server and enterprise environments. It operates at a rapid speed of 2933MHz, providing a PC4-23466 data rate that significantly enhances system performance for memory-intensive tasks. The dual-rank (2Rx4) configuration, with x4 data width per rank, is optimized for efficient data access in multi-processor systems and high-density memory configurations. The module features a CAS Latency of CL21, which is a measure of its responsiveness. While higher latency numbers generally indicate slightly slower access times compared to lower CL values at the same frequency, the overall performance is a balance of speed and latency. The standard 1.2V operating voltage ensures compatibility with modern DDR4 server platforms and contributes to power efficiency. As an RDIMM, it includes onboard registers to buffer address and command signals, reducing the load on the memory controller and enabling higher memory capacities per channel. This is crucial for servers that need to support large amounts of RAM. Furthermore, the inclusion of ECC (Error-Correcting Code) ensures data integrity by detecting and correcting single-bit errors, making it suitable for mission-critical applications where reliability is paramount. This module is designed to meet the rigorous demands of data centers and high-performance computing.
