I am currently running my system using 2 of my 4 banks in dual channel with a matched pair of 512MB PC 3200 sticks of Ram. So riddle me this, I now want to fill the other 2 banks with another 2 sticks of 512MB PC 3200 Ram. If the new pair I'm getting is comparable specs, the only difference being that the set I already have is Corsair, and the new set will be Kingston, should that create any problems for me? I'm not worried about very small drops in effeciency, b/c I'll just overclock untill I am back to normal or beyond, but I just want to make sure that all 4 banks don't have to be identical, just each set of two.?
