Hmmmm, from what i remember from reading and my PC repair class, its either a dual channel issue, a memory controller issue, and a placement issue. But you said that it wont work with 2 in any setup. Have you tried slot 1 and slot 3? or even slot 2 and slot 4? It may be a bios setting or a jumper. So many thing it could be (maybe not a jumper as much as others).
