Samsung M393A4G40AB3-CWEBY 32GB PC4-25600 ECC Reg DIMM Memory

Product Description

This Samsung M393A4G40AB3-CWEBY module is a 32GB memory component designed for server and workstation environments. It operates using the DDR4 standard, identified by the PC4-25600 rating, which corresponds to a speed of 3200MHz. This high frequency ensures rapid data transfer rates, crucial for performance-intensive applications. The module is an ECC Registered DIMM (RDIMM), meaning it includes a register chip that buffers command and address signals. This buffering reduces the electrical load on the memory controller, allowing for greater memory capacity and improved system stability, especially in systems with multiple memory modules. The module's specifications indicate a CAS Latency (CL) of 22 clock cycles. This value, along with the memory speed, determines the module's responsiveness. The 'M393A4G40AB3' part of the SKU suggests it is a 32GB module, and the 'CWEBY' suffix often denotes specific revisions or configurations. While the exact rank and organization (e.g., 1Rx4 or 1Rx8) might not be explicitly stated in this abbreviated title, it is designed to be compatible with server motherboards that support such high-speed RDIMMs. Crucially, this module features ECC (Error-Correcting Code) functionality. ECC memory is standard in server environments as it provides enhanced data integrity by detecting and correcting common types of memory errors. This capability is vital for preventing data corruption and ensuring system uptime in critical applications. The Samsung M393A4G40AB3-CWEBY is a reliable choice for upgrading or populating servers and workstations that demand high performance, capacity, and data accuracy.
