Transcend's JetRam memory modules are manufactured using carefully tested ETT-grade branded DRAM chips that have passed Transcend's strict quality controls and testing procedures. The modules offer excellent compatibility and thoroughly tested reliability, making them ideal for PC upgrades at an attractive price. Each memory module is designed for 3200 Mbps to maximize data transfer efficiency with a higher bandwidth of up to 25.6 GB/s. Transcend's DDR4 SO-DIMM JetRam memory modules operate at a nominal voltage of only 1.2 V, which helps to reduce both the operating temperature and the electrical load on the memory controller. Compared to standard DDR3 modules with 1.5 V, this saves up to 40 percent energy.
