Description
The Samsung M393B5170EH1CF8Q4 is a 4GB DDR3 Registered DIMM (RDIMM) module engineered for server and workstation applications where data integrity and system stability are paramount. It operates at a frequency of 1066MHz, providing a bandwidth of PC3-8500. The RDIMM design incorporates an onboard register that buffers address and command signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system performance in multi-module configurations. This module is dual-ranked (2R), which can enhance performance by allowing the memory controller to interleave access between the two ranks. It features CAS Latency (CL) of 7, indicating the number of clock cycles between the memory controller issuing a column-read command and the data becoming available. The inclusion of ECC (Error-Correcting Code) is a critical feature for server environments, as it automatically detects and corrects single-bit memory errors, preventing data corruption and ensuring continuous operation. Designed for reliability, the M393B5170EH1CF8Q4 is suitable for a wide array of enterprise computing tasks. Its specifications make it a dependable choice for servers running critical applications, databases, and virtualization platforms. Users should verify compatibility with their specific server model and motherboard specifications before installation to ensure optimal performance and stability.
