Q: ok i have 4 slots and there like this............ BLUE 1 BLUE 2 BLACK 3 BLACK 4 i have the 4 sticks i have two 1gb sticks and two 512mb sticks and the owners manual does not say where to put them
A: The coloured slots are used for RAM to be put into a mode called DUAL CHANNEL mode (look this up in Google for a better explanantion), where the memory is accessed faster. I.e 2 in blue or 2 in black. Or 2x512mb in blue and 2x1gb in black. So all you have to do is pair them so there in dual channel mode.
