Product Overview
The Samsung M393A2K43BB1-CTD is a 16GB DDR4-2666MHz ECC Registered DIMM (RDIMM) designed for enterprise server and data center environments. Operating at 1.2V with a 2Rx8 dual-rank configuration, this module delivers reliable, high-bandwidth performance for mission-critical workloads including virtualization, database operations, and high-performance computing. Samsung RDIMMs incorporate an additional hardware register between the DRAM and the system memory controller, reducing electrical load and ensuring sustained stability at scale — making them the default memory choice for server-class deployments.
