Hi, I have the following installed:
6x 2GB 2Rx8 - #500202-061 – Currently installed

And need to install the following:
4x 8GB 2Rx4 - #500205-071 – Needs to be installed

Are there any issues in having 2GB and 8GB DIMMS installed? and is this possible?

    Yes, you can mix, 2GB and 8GB DIMMs.

    You configuration is possible.

    At present, you may have

    2GB DIMMS in Channel 1 Slot 3 (Position A) for CPU1 and CPU2
    2GB DIMMS in Channel 2 Slot 6 (Position B) for CPU1 and CPU2
    2GB DIMMS in Channel 3 Slot 9 (Position C) for CPU1 and CPU2

    When you add the next 4 x 8GB DIMMs they must be added as follows

    8GB DIMMS in Channel 1 Slot 2 (Position D) for CPU1 and CPU2
    8GB DIMMS in Channel 2 Slot 6 (Position E) for CPU1 and CPU2

    Thanks for the response hanccocka!
    I made a mistake on providing the info I have the following setup at the moment:
    8x 2GB (500209-061)

    9C - 2GB (500209-061)
    8F - Empty
    7I - Empty
    6B - 2GB (500209-061)
    5E - Empty
    4H - Empty
    3A - 2GB (500209-061)
    2D - 2GB (500209-061)
    1G - Empty

    1G - Empty
    2D - 2GB (500209-061)
    3A - 2GB (500209-061)
    4H -Empty
    5E - Empty
    6B - 2GB (500209-061)
    7I - Empty
    8F - Empty
    9C - 2GB (500209-061)

    I tried adding the 8GB DIMMS to 5E and 6F for CPU1 and CPU2 and am still getting the beeps when attempting to bootup ...

    Any ideas?

    Allocation should be A - G.

    If you remove ALL the 2G DIMMs, do the 8GB boot the server?
