    As the title says, I got a Maximus IV Extreme-Z (Which has two bios chips). I updated the first bios chip to the latest 1004 version and now when I try to boot it up I get the error code 55 on my debug leds which means "No memory installed" (And there clearly is). Now, when I change back to chip two, on version 0206 I think, it boots fine with the same ram.

    Tried the USB bios flashback, tried resetting cmos and it won't even post on the first chip so I can't do anything other than that, can I?
    Any suggestions how to fix this would be greatly appreciated

    It may sound obvious, but have you tried changing with various RAM configurations from the ASUS manual? I know that sometimes if RAM is put in say DDR 3 & 1 SLOT this can happen

    Although I suspect your ram channels on the board may be damaged if not the ram it self but I doubt that?

    I think there's a button on the motherboard you have to push to set up the ram. Has the new bios does not new what ram is installed.

    Should the above advice not work, can your board flash the second BIOS directly back to the first? I know you said you've tried using USB but doing it directly may yield better results.

    If the old bios is fine, i would go for a bad bios flash. Put it back the way it was , check it works ok then start again.

    Yeah I have, tried it with both sticks in each slot in every combination. The ram channels can't be damaged seeing as it works fine from the 2nd bios chip :/ This is really confusing me now.
