The movement of data between the RAM and the CPU depends heavily on memory channels. In essence, a memory channel is the channel that data passes through. Multiple channels pci slots full formare generally supported by modern motherboards; the most popular configurations are dual and quad channels. Two DIMMs are placed in pairs in a dual-channel configuration, enabling simultaneous data transfer between the two modules. When compared to a single-channel setup, this practically doubles the bandwidth available for memory operations.
