Product Description
The Samsung M393A4K40BB2-CTD8Y is a 32GB DDR4 Registered DIMM (RDIMM) module, engineered for demanding server and workstation environments. It operates at a higher speed of 2666MHz compared to some standard DDR4 modules, which translates to increased bandwidth and improved performance for data-intensive applications. The RDIMM design includes an onboard register that buffers address and command signals, reducing the load on the memory controller and enabling higher memory capacities and system stability. This module features a 2Rx4 configuration, indicating it is dual-ranked with four DRAM devices per rank. This architecture allows for more efficient use of the memory bus by enabling concurrent access to different ranks. The CAS latency is CL19, meaning it takes 19 clock cycles for the module to respond to a column read command. While higher than CL17, the increased speed of 2666MHz often compensates for this in overall system performance. As an ECC RDIMM, it provides error detection and correction capabilities, which are critical for maintaining data integrity and system reliability in mission-critical applications. Samsung's reputation for quality manufacturing ensures that this memory module meets stringent performance and endurance standards required for enterprise-level deployments.
