This RAM is Approved for use with AMD RYZEN. Energise your DCC PC With Dual Channel DDR4 RAM. The data path is doubled by using two sticks of DDR4 memory. By giving the CPU bridge more data path to the memory, bandwidth is effectively doubled. In simple terms, think of dual Channel DDR as widening the bridge by adding two more lanes. This effectively allows more data to travel faster; much like traffic moving faster when there’re more lanes to drive in.
