    Bios Flash Will not work

    Hello forum, I am trying to flash my maximus XIII

    Put the cap file in the root of the flash drive restarted pc went into ezflash
    It tells me this is not a correct file to use?

    or the old school method ??

    Your board has the BIOS flashback button built in where you can flash the bios even without a CPU, RAM or GPU installed if you want.

    Try this, right from your manual. just make sure the USB is in the slot marked BIOS.
    Make sure the USB is formatted fat32 and nothing else is on it but the BIOS file named M13H.CAP
    Light will start to flash and it usually takes a minute or two. If it flashes then stops immediately something isnt right like wrong name or USB in wrong port.
    Also best to clear CMOS before beginning.

    you are a gentleman and a scholar

    Before the flash my memory bandwidth was 32.5 Gb/sec
