does dual channell work between the RAM sticks
Not to be rude, but you should look up "dual channel RAM" sometime. You can't have a dual-channel RAM setup with only one stick of RAM.
As for the rest of your question, to be honest, you'll seriously have to get out your mobo manual and read the section on the RAM slot specs. Not all boards support DC, and some boards only support DC for 2 sticks, not 4.
