  1. If I install 2 x 512 MB RAM running in Dual Channel, and then install an additional 512 MB stick for a total of 3 sticks of 512, will the first 2 still run in Dual Channel?

    It depends on the system, without more information we can't give you a proper answer.

    The newer Athlon64s (including the Venice core) are more flexible when it comes to using DIMMs with different sizes but if I'm not mistaken the memory should still be installed in pairs (2 or 4 DIMMs).

    Using 3 DIMMs will either make the CPU work in single-channel or maybe the system won't even POST.

    He has an Athlon64 which differs quite a lot from a nForce2 memory controller.
