Transcend 4GB DDR4 SDRAM Memory Module - For Desktop PC - 4 GB - DDR4-2666/PC4-21333 DDR4 SDRAM - 2666 MHz - CL19 - 1.20 V - Unbuffered - 288-pin - DIMM - Lifetime Warranty - TS512MLH64V6H-I

Designed for high-end desktop PCs, Transcend's DDR4-2666 U-DIMM memory modules can perform in a wide range of operating temperatures (from -40°C to 85ºC) and are fully compatible with Intel 9th generation Core CPU. Each module is constructed of top quality DRAM chips and rated at 2666MHz, maximizing data transmission efficiency at a bandwidth of up to 21GB/s. Operating at a nominal voltage of just 1.2V, Transcend's DDR4-2666 U-DIMMs allow for a lower electrical load on the memory controller, consuming up to 40% less power than standard 1.5V DDR3 DIMMs.
