I have two RAM slots, that are dual channel. Currently I have two 4GB ballistix sport lt 2400 sticks in them. If I were to buy an 8GB ballistix sport lt 2400 that is exactly the same, except for the size, would it work correctly with one of the 4GB modules, for a total of 12GB? Couldn't find a clear answer on this, I have seen mixed answers. Thanks ahead of time!
