I did some research and found out that dual channel isn't as picky as the manufactorers say, just to make you get the "dual channel" packs. Just needs two pairs together to work (not even same size, latencies or speed.)
I liked the heatspreaders on the ram, so that was what basically persuaded me to go with them over corsair value and other companies. The timmings are not too bad either (I think Corsair value was cl. 3.)
