I currently have a computer with 2 x 512 sticks of PC5400 675mHz DDR2 RAM, dual channeled. I was wondering, if I were to put two more sticks of RAM in the computer on the other channel, would they have to be the same speed as the first one or can they be different? I know that when you dual channel the two sticks you put in have to be the same speed, but what about the other channel? This might be a noobish question, but up till now I've never really thought about it.
