I'm not sure you even need a tutorial. Your motherboard manual should show you how to run your RAM in Dual Channel mode (or Tri/Quad channel - depending on motherboard).
In general, to get your board to work in dual channel you need a pair (two sticks) of RAM of the same frequency, CAS latency, and manufacturer. Next put one stick in Channel A (Sometimes labeled Channel 1) and the other stick into Channel B (or 2).
Really all there is to it. Your motherboard or CPU should auto-detect when the RAM is configured for dual channel and automatically enable it at POST.
