    sc990 is normally hdd/software errors

    taken from the af2090

    SC990: Software Performance Error 1
    Definition [B]
    An unexpected operation was encountered by the software.
    Possible Causes
    Software crash; reboot the machine
    Procedure 1
    If the HDDs have just been replaced, be sure to download the stamp data (SP
    5853).
    Procedure 2
    With SP5990 004 (SMC Report . Logging Data), print the most recent information
    for SC990. The SC990 information displays the file name, line number, and value.
    Report this information to your technical supervisor. For example:

                positive. i swapped back the old board and problem came back. weird huh?

                i have learned that problems are sometimes caused by the furthest thing related to the error code.

                thats why i like to check this forum cause you find solutions that are not in any manuals but by experience.
