    Default Do you know what the Debug Code bF- means on the Z170 Gaming GT Motherboard?

    I looked in the manual and the only code that resembles this is "6F" . There is no "bF"
    from searching the net I have found people with the X99 Boards talking about the Q Code "bF" as being an error.
    In the manual for the Gaming GT it says the code 6F is reserved and does not say it is an error.

    I am concerned because once completely booted my Debug code would settle at "A0".

    I really have done a lot of work figuring things out like I finally ditched the Gigabyte App Center
    because looking in "Security and Maintenance" in the Control panel I saw that Windows was not shutting
    down properly because the App Center EZtune Engine Service and other apps would not shut down as they
    should. So thats fixed.

    I flashed my bios to the latest F4f about a couple of weeks ago i think.

    I also enabled the Raid Controller and created a Raid 0 array for some games and frankly just to make sure it works

    So those are the changes I have made but I am wondering why the Debug Code is now showing i guess "6F"

    Does anyone know what this code actually means?

    In the past I've found that the EVGA motherboard user manuals usually have the most complete debug post code descriptions.

    Hopefully the attached file will help.

    Keep in mind that many of the post codes indicate that a specific initialization routine has started and that these are not debug codes unless your system stops prematurely.

    Hi ProfJim

    Thanks for the help. I actually called Tech Support about it. First off I was told there is no Code = to bF. So the code is 6F. In the manual it says the codes 6B-6F are reserved
    and that there is no particular Definition to these codes. I was told they are Random codes and if the Computer is functioning properly then don't worry about it.

    The only thing my computer is doing that I cant figure out is when I do a Shut down (Turns PC Off) apparently something is triggering a Critical Event in the Stability Index "Windows was not properly shut down" but when you view the details of the event it says , The previous system shutdown , date, was unexpected.

    I wonder if this code 6F might be related to this "Stability Index" message. The Stability Index in Windows 10 can be found going to the Control Panel then Security and Maintenance and then from Maintenance you click on view Reliability History.

    I have never seen any Windows OS have this type of monitoring tool the user can access. It really is quite cool because Windows tries to fix the stability issues if it can. But this Shutdown issue does not register as a Stability Event that can be solved by Microsoft or anyone.

    Everyone using Windows 10 should look at the Stability Index to see what Programs, Processes, Services and Apps might be causing issues.

    anyway I am going to try and not think about that code now and take Gigabyte's advise. This is the time when you might not want a big window on the side of your case right? lol
