Transcend JetRAM 8GB DDR4 SDRAM Memory Module - 8 GB (1 x 8GB) - DDR4-2666/PC4-21333 DDR4 SDRAM - 2666 MHz - CL19 - 1.20 V - Unbuffered - 288-pin - DIMM - JM2666HLB-8G

Transcend's JetRam memory modules are manufactured with true ETT grade, brand-name DRAM chips that have passed Transcend's strict screening process and rigorous environmental testing. The modules provide excellent compatibility and fully-tested reliability, which is ideal for PC upgrade at an attractive price. Each memory module is rated at 2666MHz to greatly increase data transmission efficiency by higher bandwidth of up to 21GB/s. Operated at a nominal voltage of just 1.2V, Transcend's DDR4 U-DIMM JetRam memory ensures that both operating temperature and electrical load on the memory controller can be reduced in order to save up to 40% of energy compared to standard DDR3 modules offering 1.5V.
