Transcend's JetRam memory modules are manufactured using carefully tested (ETT-grade) brand DRAM chips that have passed Transcend's stringent 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 MT/s to maximize data transfer efficiency with a higher bandwidth of up to 25.6 GB/s. Transcend's DDR4 U-DIMM JetRam memory modules operate at a nominal voltage of just 1.2 V, which helps reduce both the operating temperature and the electrical load on the memory controller. Compared to standard DDR3 modules with 1.5 V, this results in energy savings of up to 40 percent.
