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. Each memory module is rated at 3200MHz to greatly increase data transmission efficiency by higher bandwidth of up to 25.6GB/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.
