Dual Channel DDR2 effectively increases the data transfer rates and bandwidth of DDR2 memory. Dual channel DDR2 offers 30% higher bandwidth while considerably lowering power consumption. This also results in less heat build-up; thereby putting less stress on your system. To make optimal use of the Dual Channel capability, a pair of identical memory modules must be placed in matching DIMM slots. These DIMM slots are usually color coded for easier installation
