Description
The Samsung M393A8G40MB2-CTD7Q is a high-density 64GB DDR4 Registered DIMM (RDIMM) module, engineered to deliver exceptional performance and reliability for enterprise-grade servers and workstations. Operating at a rapid 2666MHz, it provides significant bandwidth to handle complex computations and large datasets efficiently. The CL19 CAS latency is optimized for this speed, ensuring timely data retrieval. This module features a 2Rx4 dual-rank configuration, which enhances performance by allowing the memory controller to access different sets of memory chips concurrently. As a Registered DIMM, it includes an onboard register that buffers address and command signals, reducing the electrical load on the memory controller. This enables higher memory capacities and improved signal integrity, crucial for stable operation in demanding server environments. With built-in ECC (Error-Correcting Code) functionality, the M393A8G40MB2-CTD7Q can detect and correct single-bit errors, significantly reducing the risk of data corruption and system crashes. This makes it an indispensable component for mission-critical applications where data accuracy and uptime are paramount.
