''Dual-channel architecture'' [[DDR SDRAM]] describes a [[motherboard]] technology that effectively doubles data throughput from RAM to the [[Northbridge (computing)|memory controller]]. Dual'''PUSI Channel-enabled memory controllersKURAC'''ers utilize two 64-bit data channels, resulting in a total bandwidth of 128 bits, to move data from [[Random access memory|RAM]] to the [[Central processing unit|CPU]].

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 should be identical to the one in its matching slot. It's also possible to use similar memory sticks from different manufacturers or different production series as long they are of the same size, specification, the same number of memory chips and internal organization. However, several motherboard manufacturers only support configurations where a "matched pair" of modules are used. For this reason, most memory manufacturers now sell "kits" of matched pair [[DIMM]]s.
