The M393A8G40AB2-CWE is a Samsung DDR4 memory module with a large 64GB capacity, ideal for high-performance computing and server applications. It utilizes an RDIMM (Registered DIMM) architecture, offering greater stability and fault tolerance, enabling it to handle more memory requests simultaneously. The 2Rx4 designation indicates a dual-path implementation, with each DRAM chip using two data lines for data read and write, enabling faster data transfer. The high frequency of 3200Mbps enables faster response to computer read and write requests, improving overall computer speed. Its low 1.2V voltage makes it more energy-efficient, reducing overall power consumption and heat generation, making it suitable for applications requiring low voltage. The module features a 288-pin design and a 4Gx4 memory structure (each DRAM chip holds 4GB), with 36 banks, offering higher storage density and supporting larger memory capacities.
