About the Samsung 16GB DDR4 RDIMM - DDR4 (M393A2K43DB3-CTD)
A single Samsung DDR4 RDIMM at 16GB capacity enables enterprise servers to scale memory configurations up to 768GB per system—the standard ceiling for high-density compute platforms. The M393A2K43DB3-CTD is a registered ECC module engineered for mission-critical infrastructure, delivering 2666 MT/s throughput with dual-rank (2Rx8) organization and full error correction. Built on Samsung's proven 10nm-class DRAM fabrication, this 288-pin RDIMM combines the reliability of on-die ECC protection with 1.2V efficiency, making it the foundation for virtualization hosts, database servers, and analytics clusters that demand zero unplanned downtime.
Storage architects and IT procurement teams standardize on Samsung's DDR4 RDIMM portfolio because registered buffering isolates signal integrity across large-scale memory arrays, while CAS latency 19 and JEDEC DDR4 compliance ensure compatibility with the broadest range of enterprise platforms. Organizations deploying Xeon-based servers, hyperconverged infrastructure, or big-data appliances rely on the M393A2K43DB3-CTD to populate DIMM slots efficiently and maintain consistent performance across multi-node environments. The on-die ECC architecture catches bit-level corruption before it propagates to workloads, protecting revenue-generating applications and meeting compliance requirements in regulated sectors.
