Hey there, friendly tech support guys! :smile: My system is currently housing two 512 sticks of PC3200 RAM (typical, I know). I know that they are running in dual-channel, because they are specifically said to support it, and because my ASRock motherboard supports it. One of the nice features of my mobo is that is has four memory slots (w/ support for two sets of dc memory). Now to the question: If I buy one 512 stick of PC3200 RAM and put it in, then, in a few months, buy exactly the same stick of RAM again and install that beside it, will they run in dual-channel? Or do I have to buy a 'kit' that specifically mentions that it supports dc? In other words, will buying two identical pieces of RAM and putting them in a dc-supporting mobo (even if they don't specify rather they are dual-channel or not) always result in correct dc operation? Thanks in advance!
