Ok so I got my pc today and the guy who made it (he has his personal shop and he is well known)he said that he tried to put two stick of dd4 4gb ram (kingston hyperx 2400 mhz)in the a2 and b2 slots but he had problems with it so he put one stick of 8gb but I asked him did you put it in the a2 and b2 (because I think thats where you should put them)slots for dual channel and he said that he tried everything he can.So Ive been pondering this even since and I really need your guys help because I believe he did not put them as intended for dual channel.
