    Can anyone tell me if my RAM is inserted properly in the correct DIMS
    to make a matched pair ?

    thanks !!

    yep yep, youre all good.

    the next ram you add, youd add into 3&4 in Riser Card A

    If he bought 2 more 2 GB memory sticks, would be better to move his 2 X 1 GB sticks into slots 3 & 4 on Riser Card A, and put the 2 new 2 GB sticks into Riser Card B, slots 1 and 2. Or would it make any difference?

    If it made any difference, it would likely be so small you'd never notice. If it's running correctly the way it is, I'd leave it alone.

    Yes, it would make a difference. Matched pairs in risers A & B is the way to go.

    So would it be better to move them in matched pairs
    instead of what i have now ?

    No, moving them won't do anything for you but make it worse than it is now. We're saying buy another 2 X 2GB sticks, put these new sticks in Riser B, slots 1 & 2, just like Roy suggests. The 2 X 1GB sticks go into Riser A, slots 3 & 4.

    Eventually, buy another 2 X 1GB sticks for Riser B, slots 3 & 4, and then you have two matched pairs in both risers, and 12GB total RAM. This won't help much now in OS 10.5, but it will in Snow Leopard 10.6.
