Hi guys, I wanted to ask if you could you tell me what kind of support my RAM slots and they do not understand why a large. I mean I have a mobo Asus M2N-NMS in this photo. Now I have two yellow slots DDR2 1GB each so I have no problem for these slots but I do not know how do you know what kind of support the other two RAM slots because blacks do not fit any RAM currently and appear different from the yellow ones. I tried SIW but does not tell me anything about it. I also did not understand why there are slot of a different color. I read something about the dual channel but I did not understand much.
