Memory runs along a 64-bit pipeline. Dual channel requires matching sizes, speeds, and latencies of RAM to be installed (2x1GB sticks, for example) in certain slots to work.
This effectively doubles the memory bandwidth to 128-bit.
You can mix memory sizes as long as each channel is matched.
If you mix RAM of different speeds, the faster RAM will underclock to match the slower RAM.
Dual-channel can provide up to a 5% boost. That's not much, but it's free and better than nothing. Keep in mind that adding a third stick of memory of a decent size will probably still give you a boost even though you are now running in single channel.
