Multi-channel memory architecture

Dual channel DDR_SDRAM is a motherboard technology used to increase memory performance, by using two channels to load data into memory. The memory controller utilizes two 64 bit channels to the memory, resulting in a total of 128 bits, effectively doubling the bandwidth to memory. In order to achieve this, the DDR_SDRAM memory modules must be installed into matching memory slots, which are usually color coded on the motherboard. Each memory module in each slot must be identical to the one in its matching slot.
