I am trying to install new sticks of ram into my A7N8X-Deluxe mobo. I currently have 2x1 gigs of DDR400 OCZ ram, and i also have 1 stick of 512 Kingston DDR 400 value ram. I am trying to figure out in what order i should be placing these sticks. Like which sockets should my 2x1 gigs of OCZ and which socket should my 512 kingston sticks go to? It looks like DIMM 2 and 3 are blue color coded and DIMM 1 is black color coded, but DIMM 1 & 2 are close together while DIMM 3 is further away from both DIMM 1 & 2. I am very confused. I want to use my 2x1 gigs of OCZ DDR 400 ram in dual channel while my 512 Kingston DDR 400 dosen't interfere but is still being used in my PC as additional ram. Any help is much appreciated!

I tried calling technical support, but he didn't say much and left my even more confused because all he literally said whenever i asked him a question was, "yes, uh huh". I don't think he was even listening to me.
