The board physically has 3 slots, 2 closer together, another separate. The two are one channel, the other one is the other channel. Put the same amount of ram in both channels (i guess keeping an empty slot in between the two sticks would ensure that they are in different channels. It shouldn't matter what is in either channel, (two sticks on one, one on the other, or one in each) as long as each channel has the same total capacity. Then when you boot up, POST will explicitly indicate that it is running in dual channel mode with a message like "Dual Channel Memory Enabled" or something like that (I forget exactly what it says. I wouldn't trust any software to tell me about my hardware. There are no BIOS settings to enable Dual Channel Ram. I hope i helped...
