so, i recently bought this mobo to work with my brothers old parts. everything seems good but for the fact that it doesent run on dual channel. i have 2x2gb ram sticks which run ok on the A1 slot by themselves but wont boot on the B1 slot (the mobo has only 2 slots). The mobo detects both identically as you will see on the picture i attached. Since the ram is on the compatibility list on the mobos webpage at first i tought it was the mobo slot, but after getting a replacement its all still the same, which makes me believe the mobo just needs the stick to be on slot A when its only one?. I will test the rams on another pc and try to get hold of other rams to test with the mobo but it will be difficult for me. Any ideas if its really a compatibility issue or something else?
