    Random BSOD's [ntkrnlmp, ntoskrnl, rt640x64] + PC Freezes while Gaming


    Hello all!

    I have previously posted in this specific forum due to random BSOD's which had mostly taken the error of
    but it has been quite a while since that post [I'll link it here] and I have lacked the time. Nevertheless, since lowering the RAM frequency, I have been getting blue screens regardless and so I assume that it took no adverse effect to the problem.

    I'd like to also point out that rt640x64.sys was a particular cause into the
    error and so I manually found and downloaded the relevant driver for Realtek 8136/8168/8169 PCI/PCIe Adapters" as mentioned on WhoCrashed. Although, this did not resolve the issue.

    To add on to the problem of these blue screens, I have also witnessed many accounts of a whole PC freeze if not a blue screen while playing games such as Rocket League and more recently Killing Floor 2. These spikes have taken various amount of time and can either semi-freeze my PC (I can still communicate through Discord) or a complete halt on the system (reset required). I've also noticed my GPU load at 100% at these times and RAM usage is also at a constant ~4GB out of the total 8GB (all the time & at idle) which I'm curious about.

    Quite a bunch of information here, but any help whatsoever is much appreciated!

    :)

  2. Multiple BSODs caused by ntkrnlmp.exe in Windows 10

    Also, i not that to geeky to comprehend what was written in the .DMP file, you can also check this:

    BSOD - ntoskrnl.exe & ntkrnlmp.exe Solved - Windows 10 Forums

    it says that it regards the BIOS. . . . ?

  3. Getting multiple BSOD's a week, no clue what the problem is.

    These seem to be happening pretty much at random. Could be happening while playing games, but also while I'm not even active on the computer. Also doesn't seem related to how long the PC has been running. No idea if it's of any importance but I'll also add
    that not every crash is a BSOD. Sometimes it just freezes and I will have to reboot it myself.

    These are my minidump files from my BSOD just a few minutes ago: Minidump.rar

    Random BSOD's [ntkrnlmp, ntoskrnl, rt640x64] + PC Freezes while Gaming

    Latest dump has:
    Code: BugCheck 12B, {ffffffffc00002c4, 43b, 18287300, ffffad00f3853000} Probably caused by : memory_corruption[/quote] Code: FAULTY_HARDWARE_CORRUPTED_PAGE (12b) This bugcheck indicates that a single bit error was found in this page. This is a hardware memory error. Arguments: Arg1: ffffffffc00002c4, virtual address mapping the corrupted page Arg2: 000000000000043b, physical page number Arg3: 0000000018287300, zero Arg4: ffffad00f3853000, zero[/quote] Time to test your RAM with memtest86+ (note the +). You have 8GB so 10 to 12 hours will be needed to let it run a minimum of 8 full passes. Any error indicates bad ram and you can stop the test and replace it.

    ===================================================
    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.


    Random BSOD's [ntkrnlmp, ntoskrnl, rt640x64] + PC Freezes while Gaming [​IMG]
    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.


    Random BSOD's [ntkrnlmp, ntoskrnl, rt640x64] + PC Freezes while Gaming [​IMG]
    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.

    Hello, thanks for the advise and analysis!

    I have been able to run MemTest86+ for a whopping 20 hours and fortunately, I have accumulated 10 total passes an no errors! (see attached picture)
    So I assume the problem lies within the software side of things...?

    Thanks!

    Yes, probably a drivr issue. Let's give Driver Verifier a try:

    ===================================================
    Driver Verifier
    is a diagnostic tool built into Windows 10, it is designed to verify both native Microsoft drivers and third party drivers. Driver Verifier's verification process involves putting heavy stress on drivers with the intention of making bad, outdated, incompatible or misbehaving drivers fail. The required result is a BSOD (Blue Screen of Death) which will generate a crash dump for debugging purposes.
    Machines exposed to Driver Verifier will run very sluggishly due to the stress being applied to the drivers.

    Driver Verifier - Enable and Disable in Windows 10

    Pay close attention to

    PART TWO
    Random BSOD's [ntkrnlmp, ntoskrnl, rt640x64] + PC Freezes while Gaming [​IMG]

    and make sure the correct boxes are checked.

    Warning:
    It is not advised to run Driver Verifier for more than 48 hours at a time. Disable Driver Verifier after 48 hours or after receiving a BSOD, whichever happens soonest.

    Always create a Restore Point prior to enabling Driver Verifier.

    What we're looking for is a BSOD with a mini dump that will tell us what driver caused it.

    Hello again!

    It's been a while since I've updated on what's going on but I've been running Driver Verifier since you posted, so a couple odd days. However, judging by the advice on how long you should be running it for (48 hours), I decided to turn it off today as I didn't have any BSOD's while it was on in the background.
    Unfortunately, while I left the PC for a while, I return to find it had Blue Screened *Shock, back with the same causes ntoskrnl.exe and ntkrnlmp.exe​. Would this mean I should re-enable DV again?

    I've attached the dump.

    Thanks!

    No, DV is only used to try to cause device driver failures by making them work harder. You should not run with it enabled normally. It slows things down for sure.

    I see some pretty old drivers on your system. For example:
    Code: 2008/07/26 14:29:37 \??\C:\Program Files (x86)\NZXT\CAM\CAM_V3.sys 2011/07/12 22:00:01 \??\C:\Program Files\SUPERAntiSpyware\SASKUTIL64 2011/07/22 00:03:00 \??\C:\Program Files\SUPERAntiSpyware\SASDIFSV64 2012/12/04 09:49:28 C:\WINDOWS\system32\drivers\amdide64.sys 2012/12/11 21:21:44 C:\WINDOWS\system32\drivers\amdsbs.sys 2013/01/15 06:25:51 \??\C:\WINDOWS\SysWOW64\Drivers\AsrDrv101.sys[/quote] They may be perfectly fine but appear to be left over from a previous install. Did you upgrade from Windows 7 or 8 to 10?
    If so, this might be a good time to backup your system then do a Clean Install of the latest available Windows 10 which is 14393. Apply all updates and it will make is 14393.479.

    Restore your data and see how it runs.

    Heyo,

    This was a clean OS install, via the USB-image install method. I am currently running build 14393.576 (recently updated) and while I haven't had any BSODs, I have been getting frequent lock ups when the GPU is on max load (ie. via gaming). I've also suffered general video driver crashes (due to Radeon WattMan? even though it's off) so I'm not sure if that has a correlation to this.

    However, I'll try and do a clean install as soon as and investigate whether the blue screens persist!

    ​I've completely reinstalled the OS and all was going well. However, I've unfortunately received a blue screen today bearing the name
    and 2-3 lock ups. I've attached the dump, thanks!

    Ah interesting, that's quite unexpected to say the least. I've never had problems with Avast; but there seems to be an update for it, so I'll see if that fixes up this, else I'll uninstall and resort to Windows Defender. Thanks!

    Hello, it's been almost a week and I've actually had no blue screens within that time. However that streak came to a close with a blue screen:
    Quite worrisome as I haven't had this particular error before and I had checked that there was no RAM problems whatsoever.

    Latest dump indicates a problem with atikmdag.sys.
    Code: ffffe402`09e8d1b8 fffff803`57f6fb54*** WARNING: Unable to verify timestamp for atikmdag.sys *** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys atikmdag+0xdafb54[/quote] This belongs to the ATI Video driver.

    Remove and install latest ATI Radeon drivers:

    I suggest completely uninstalling the ATI display drivers using Display Driver Uninstaller (DDU) from WagnardMobile (near bottom of page) then get the latest driver for you ATI Radeon card here: SAPPHIRE NITRO Radeon™ R9 380 4G D5
    Then install only the graphics driver, not the Catalyst Control Center.

    See if that gets rid of the problem.
