64GB DDR5 Gaming RAM with Heatsink

Show More

Energise your PC With Dual Channel DDR5 RAM for maximum speed. The data path is doubled by using four sticks of DDR5 memory. By giving the CPU bridge more data path to the memory, bandwidth is effectively doubled. In simple terms, think of dual Channel DDR5 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 such as Kingston / Corsair / G. SKILL / Crucial
