    If the processor is not specifically supported by the board an error will be noted.

    It is hard to tell from here without knowing the board make & model.
    If you can provide that we can look up the manual.

    I, for example, have way over-processed my board & at every boot am told that the CPU code was not found.

    Press F1 to continue. This is what I have to do in order to use my processor.

    This may be your case too.

    Does the board have a BIOS you can upgrade to?

    Do you have any problem other than pressing F1?
