DDR4-2666ECC Unbuffered MemoryCL=19

Stable, reliable operations are critical for both servers and workstations. Transcend's DDR4-2666 ECC-DIMMs 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. Operating at a nominal voltage of just 1.2V, Transcend's DDR4-2666 ECC-DIMMs ensure a low electrical load on the memory controller, consuming up to 40% less power than standard 1.5V DDR3 DIMMs.
