Product Description
The Samsung M393A8G40BB4-CWE is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) module, engineered for demanding server and workstation environments. Operating at a speed of 3200MHz, it provides substantial bandwidth crucial for memory-intensive tasks such as large database operations, complex simulations, and extensive virtualization. The PC4-25600 designation indicates its data transfer rate, ensuring efficient performance for data-hungry applications. This module features a CAS Latency (CL) of 22, which, in conjunction with its high frequency, offers a balance of speed and responsiveness. The 2Rx4 configuration signifies a dual-rank design with x4 data width per DRAM chip. Dual-rank modules can offer performance benefits in certain server architectures by allowing the memory controller to access different ranks independently, potentially increasing effective bandwidth. As a server-grade RDIMM, it includes onboard registers to buffer command and address signals, reducing the electrical load on the memory controller. This enables systems to support higher memory capacities and configurations. Furthermore, the integrated ECC (Error-Correcting Code) functionality is vital for maintaining data integrity and system stability in mission-critical applications, detecting and correcting memory errors that could otherwise lead to crashes or data corruption. This makes the M393A8G40BB4-CWE a reliable choice for enterprise data centers and high-performance computing environments.
