i bought 2gb times 2 corsair xm3 ddr3 1600 ram. I when i look at other corsair xm3 ddr3 1600 ram it has a slightly different color. I am wondering if i got more corsair ram that had all the same specs as mine it would work fine. I think the color might be just a minor change but i am not sure that it is not a whole different type of ram.
