DDR4-2666, ECC Unbuffered Memory, CL=19

Stable, reliable operations are critical for both servers and workstations. Transcend’s DDR4-2666 ECC SO-DIMM memory modules are fully compatible with Intel® Coffee Lake and AMD Ryzen™ processors. The memory modules feature Error Correcting Code, which monitors data being transferred in and out of memory and corrects any errors found. Each module is constructed of top-quality DRAM chips and is rated at 2666MHz, maximizing data transmission efficiency with a bandwidth of up to 21GB/s; making it ideal for small form-factor industrial computers, POS terminals, medical diagnostic equipment, and mini-ITX systems. Operated at a nominal voltage of just 1.2V, Transcend’s DDR4-2666 ECC SO-DIMMs reduce electrical load on the memory controller, consuming up to 40% less power compared to 1.5V standard DDR3 DIMMs.
