To take advantage of multi-channel memory, the processor must have a memory controller that supports the multi-channel architecture and the motherboard must support the architecture. Manufacturers found that two independent buses increased performance more, so the unganged model is usually set by default on most modern processors. The performance increases were not enough, however.

Triple-channel architecture also uses interleaving, which is a method of assigning memory addresses to the memory in a set order.įor dual-channel architecture, the original design combined two 64-bit buses into a single 128-bit bus, which was later called the ganged model. There are also a few motherboards that run triple-channel architecture. Six-channel and eight-channel architecture is usually designed for servers.

There are memory controllers built with one channel, two channels (dual channel), four channels (quad channel), six channels, and eight channels. This allows faster data exchange, as the data can be sent on more than one channel.

Some memory controllers have multiple channels for communication with the memory module. The RAM on the memory module communicates with the rest of the computer through the memory controller on the central processing unit (also known as a CPU or a processor) using a bus.
