It utilizes two funnels (thus two memory modules 2 x 2gb) to feed data to the processor, doubling the speed of traditional older single funnel designs. Dual-channel-enabled memory controllers utilize two 64-bit data channels, resulting in a total bandwidth of 128-bits, to move data from RAM to the CPU.
