DDR4-2666 R-DIMM

Designed to meet the needs of cloud computing, virtualization, and high-performance computing technologies, Transcend's DDR4-2666 R-DIMMs are fully compatible with Intel® Coffee Lake and AMD Ryzen™ processors. Each R-DIMM module is constructed of top-quality DRAM chips and rated at 2666MHz, thus maximizing data transmission efficiency with a bandwidth of up to 21GB/s. Operating at a nominal voltage of just 1.2V, Transcend's DDR4-2666 R-DIMMs ensure a low electrical load on the memory controller, consuming up to 40% less electricity than a standard 1.5V DDR3.
