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.

We use A-Grade RAM in all our gaming computers such as G.SKILL, Crucial, Corsair and Kingston.
