Dual-channel memory modules are two memory modules with the same specification, capacity and serial number in the same package.
Because a dual-channel memory is connected to the memory controller through a series of wires, it requires two sets of memory modules with the same capacity and electrical specification. Transfer speed increases as the memory bus capacity increases from 64 bit to 128 bit. Users must install the two modules in the specific DIMM slots to enable dual channel function to have a stable usage.
