The Dual Channel architecture of the DDR RAM memory modules describes a motherboard technology which doubles the effective data transfer of the RAM controllers depending on the pulsing. In principle this means that not only one RAM controller is built in the PC, but two. If the dual channel is activated for the RAM controller it uses two 64 bit data channels which offer a total band width of 128 bits in order to send data from the RAM memory module to the CPU. Newer motherboards are already equipped with this tool channel function. The differences to the single channel are differing according to the chip set and to the processor.
