Description
The Samsung M393A5143DB0-CPB20 is a 4GB DDR4 Registered DIMM (RDIMM) module, engineered for high-performance computing environments such as servers and workstations. It operates at a speed of 2133MHz, corresponding to the PC4-17000 designation, which provides a substantial increase in bandwidth and efficiency compared to previous DDR generations. The DDR4 technology also contributes to lower power consumption, making it an energy-efficient choice for large-scale deployments. This module features a 1Rx8 configuration, indicating a single rank of memory chips, each with an x8 data width. The RDIMM form factor includes a register chip that buffers command and address signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed per channel and supporting higher memory capacities and speeds, which is critical for server stability and performance. Crucially, the M393A5143DB0-CPB20 supports ECC (Error-Correcting Code) functionality. ECC memory is designed to detect and correct common types of internal data corruption, significantly enhancing system reliability and data integrity. This makes it an essential component for mission-critical applications where data accuracy and system uptime are paramount. The CAS Latency (CL) for this module is 15, contributing to its overall performance characteristics.
