Sorry forgive me if i'm wrong, but what you are describing sounds like you are trying to use 2 Banks of dimms not 2 channels, channels are the same color on your motherboard, i.e. Dimm slot A0+A1 = 1 dual channel. So for example on your setup with the Asus Mobo you would use either both the Grey or both the Black channels, some motherboards (specifically some Asus) will not allow you to use the second Dimms without first filling the primary channels.
If i have been way off i apologize, otherwise enjoy :)
