    DPC latency issue (crackling audio) dxgkrnl.sys - Windows 10

    OS - Windows 10
    x64
    What was original installed OS on system?: Windows
    Is the OS an OEM version or full retail version: Purchased a CD
    Age of system: About 3 years
    Age of OS installation - have you re-installed the OS?: Three times, current one is about a year and a half I think

    CPU: i7 3770k (Not OC)
    Video Card: GTX 680 FTW
    MotherBoard - MSI Z77 Mpower
    Power Supply - Corsair Gold 850W 80+

    System Manufacturer: Myself..
    Exact model number: ?

    Laptop or Desktop?: Desktop



    With that out of the way, I keep having crackling audio, it's not my headphones or my sound card, if I restart my PC, it goes away for a while but eventually comes back. So I got some screenshots of DPS tracker DPC latency issue (crackling audio) dxgkrnl.sys - Windows 10-a72s5l2-png and LatencyMon DPC latency issue (crackling audio) dxgkrnl.sys - Windows 10-glm6snz-png

    It's clear that DirectX kernel is the issue but I'm not sure how to fix that since all I can do is wait for a windows update? The database here says so.

    All updates usually fix something, hence the hope is they'll fix your issues...

    Nope, updated and DirectX Kernel always shows up just taking massive resources and occasionally NDIS

    Re: DPC latency issue (crackling audio) dxgkrnl.sys - Windows 10

    Speccy says slot 1 and 2 for your ram slots.
    I can't understand their configuration.
    Your manual suggests you should use DIMM2 and DIMM4 (starting from the cpu, second and fourth slots).
    Did you set them that way?

    Re: DPC latency issue (crackling audio) dxgkrnl.sys - Windows 10

    I also can see you are not using the pcie x16 slot near the cpu for your graphic card (in your manual, it is named PCI_E2).
