Product Description
The Samsung M393A8G40D40-CRB is a high-performance 64GB DDR4 Registered DIMM (RDIMM) memory module, specifically engineered for demanding server and workstation applications. This module utilizes the DDR4 standard, offering increased bandwidth and power efficiency compared to previous DDR generations. Its 2133MHz operating speed, coupled with a CAS Latency (CL) of 15, ensures rapid data access and processing, crucial for memory-intensive tasks. This RDIMM features an 8Rx4 configuration, indicating it has eight ranks of memory chips, with each rank consisting of four data bits. The registered nature of the DIMM means it includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity. This makes it suitable for systems that require a large amount of stable memory. Furthermore, the M393A8G40D40-CRB incorporates Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data reliability and system stability. This is a critical feature for servers and mission-critical applications where data integrity is paramount. The module operates at a standard voltage of 1.2V, adhering to DDR4 power specifications.
