  1.    08 Dec 2016 #1


    so this is the third BSOD in a year
    But now the BSOD message was unexpected_kernel_mode_trap
    What could it be?
    Hope the symbol files are already available

    Latest dump (12/8) shows this:
    This means a trap occurred in kernel mode, and it's a trap of a kind
    that the kernel isn't allowed to have/catch (bound trap) or that
    is always instant death (double fault).  The first number in the
    bugcheck params is the number of the trap (8 = double fault, etc)
    Consult an Intel x86 family manual to learn more about what these
    traps are. Here is a *portion* of those codes:
    If kv shows a taskGate
            use .tss on the part before the colon, then kv.
    Else if kv shows a trapframe
            use .trap on that value
            .trap on the appropriate frame will show where the trap was taken
            (on x86, this will be the ebp that goes with the procedure KiTrap)
    kb will then show the corrected stack.
    Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
    Arg2: ffffc500474d7b30
    Arg3: ffffc500489a2ee0
    Arg4: fffff8026bbdf9d0
    May or may or may not be a memory problem but let's start by testing your ram. You have 16GB so it's going to take 12 hours or so for a full 8 passes which is the minimum needed for a good test.

    Follow this tutorial: MemTest86+ - Test RAM - Windows 10 Forums

    MemTest86+ is a diagnostic tool designed to test Random Access Memory (RAM) for faults. MemTest86+ will verify that:

    • RAM will accept and keep random patterns of data sent to it
    • There are no errors when different parts of memory try to interact
    • There are no conflicts between memory addresses

    Memtest86+ runs from bootable media to isolate the RAM from the system, no other components are taken into account during the test.

    warning   Warning
    MemTest86+ needs to run for at least 8 passes to be anywhere near conclusive, anything less will not give a complete analysis of the RAM.

    If you are asked to run MemTest86+ by a Ten Forums member make sure you run the full 8 passes for conclusive results. If you run less than 8 passes you will be asked to run it again.

    Note   Note
    MemTest86+ has been known to discover errors in RAM in later passes than the eighth pass. This is for information only; if you feel there is a definite problem with the RAM and 8 passes have shown no errors feel free to continue for longer.

    Running 8 passes of MemTest86+ is a long and drawn out exercise and the more RAM you have the longer it will take. It's recommended to run MemTest86+ just before you go to bed and leave it overnight.

    I was unable to complete the 8 passes since the power went down
    Last time I saw it, it was on the 4 pass with no errors
    But I also updated the bios before you answered the thread
    When checking the list of compatible memory module I just saw that my ram was added recently(and it said it was compatible with the xmp profile), so it could have just been unstable at 2400mhz on the old bios
    I will update when I have the time to run the 8 passes of memtest
    Thank you for your help.
    By the way, I noticed that memtest86+ didnt recognize the frequency of the ram module, It said DDR3-0
    So I assume it doesnt recognizes DDR4, I dont think it would affect the test but you may know better

    So far no BSOD's, It might have been the overclocked ram all this time since the last time I updated the bios was like in march
    Well thanks for your help
    I'm gonna mark this as solved
