Samsung M393A1K43DB1-CVFCQ 8GB DDR4-2933MHz RDIMM 1Rx8 CL21 Memory

Product Description

The Samsung M393A1K43DB1-CVFCQ is a high-quality 8GB DDR4 memory module specifically designed for server and enterprise-level computing environments. As a Registered DIMM (RDIMM), it incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is crucial for enabling higher memory capacities and ensuring system stability in systems populated with multiple memory modules, a common requirement in servers. Operating at a frequency of 2933MHz, this module offers a significant performance uplift over lower-speed DDR4 modules, contributing to faster data processing and improved application responsiveness. The CAS Latency (CL) of 21 indicates the number of clock cycles required to access a particular column of data. While CL21 is a moderate latency, the higher clock speed of 2933MHz generally compensates for this, providing a good balance of speed and timing for demanding workloads. The 1Rx8 configuration signifies that the module is single-ranked, with each rank consisting of eight memory chips. This configuration is common for modules of this capacity and speed. Like most server-grade memory, this RDIMM supports ECC (Error-Correcting Code) functionality, which is vital for detecting and correcting memory errors in real-time, thereby preventing data corruption and enhancing the overall reliability and uptime of critical server operations. The standard 1.2V operating voltage ensures compatibility with a wide range of DDR4 server platforms.
