I assume that if you put either module in the board it will work OK on its own. Have you tried swapping the modules over in the slots, sometimes it helps if the larger module is in the first slot.

Asus mobo's with 3 memory slots like their memorysticks in slots 1 and 3.

I would try what realblackstuff suggests put the bigger memory stick in slot 1 and the smaller in slot 2 or 3
