I haven't seen it mentioned, but sometimes moving memory sticks around can get different results. I would start by putting two of the same sticks in and seeing what happpens. Then putting two of the other sticks in. If that works, try putting the additional sticks in the remaining slots. If that doesn't work, try switching the first two sticks with the other two. A little time consuming, but you find out if everything works, and also if a little different configuration will do the trick.
