    Maximus Debug LED Codes

    hey guys n gals, I was wondering is there a thread in these forums or a link to somewhere else that has a huge list of all the Debug codes for the Maximus Extreme motherboard?

    I havent got a problem with mine but im just interested in keeping a copy incase something bad happens :P

    Main reason is when im booting the system up the numbers change around and everything, and im just curious as to what kinda stuff its checking :P

    thats a bunch peeps!!

    They are in the GENE-Z manual, not sure if they match other boards. Other boards might have the codes in their manuals.

    They were not much help for me though, when I connected HDMI to onboard on first boot I still had to guess it was defaulting to discrete.

    I had a look at the manual as Spathi suggested and didn't find anything there within the few english pages there was..

    But after some more looking around i ended up finding a page that listed all the codes.. Apparently they say that these codes are all valid for every motherboard that has a P67 chipset that run a LGA1155 socket with an AMI Bios.. So im not sure if these are the same for other different motherboards.

    Anyways heres my findings:

    Progress Codes

    00 - Not used
    01 - Power on. Reset type detection (soft/hard)
    02 - AP initialization before microcode loading

    What means the 30 - Reserved for ASL (see ASL Status Codes section below), I've looked up in the manual and I didn't find an explanation for it.
    Thank you.

    It seems as if there is no clear explanation of the LED code 30 (other than the manual). I've noticed that if I set the mobo (in the boot setup (F2)) to Optimized default settings, it loads up as A0 (which from what I can assume is the normal status). When I click on the 4-way optimization for the comp it loads back up (after reset) as code 30. Not clear on what it means, since anything in the 30's range is for the memory, I can only assume that either the comp defaulted to the 4-way (because we all know technology has a mind of its own), or you clicked it (maybe by accident).

    For myself, it was a mixture of clicking "Gaming" profile on my ASUS ROG 760 P GPU, and clicking the 4-way optimization in AI Suite III.
