    High DPC latecy

    Hi guys,

    Recently I have been having serious issues with my audio, mostly stutters and dropouts

    I've already tried the following:
    -Latest BIOS update,
    -Reinstalled/updated drivers, even rolled back a couple of times,
    -Disable all enhancements.

    I've included my DxDiag, and I also ran a LatencyMon run:

    CONCLUSION
    _________________________________________________________________________________________________________
    Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
    LatencyMon has been analyzing your system for 0:05:11 (h:mm:ss) on all processors.

    SYSTEM INFORMATION
    _________________________________________________________________________________________________________
    Computer name: GAME-PC
    OS version: Windows 10 , 10.0, build: 16299 (x64)
    Hardware: MS-7850, MSI, Z97 PC Mate(MS-7850)
    CPU: GenuineIntel Intel(R) Pentium(R) CPU G3258 @ 3.20GHz
    Logical processors: 2
    Processor groups: 1
    RAM: 8143 MB total

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 320 MHz
    Measured CPU speed: 1 MHz (approx.)


    Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

    MEASURED INTERRUPT TO USER PROCESS LATENCIES
    _________________________________________________________________________________________________________
    The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.


    Highest measured interrupt to process latency (s): 101286,339293
    Average measured interrupt to process latency (s): 14,780613


    Highest measured interrupt to DPC latency (s): 101053,378697
    Average measured interrupt to DPC latency (s): 13,485704




    _________________________________________________________________________________________________________
    REPORTED ISRs
    _________________________________________________________________________________________________________
    Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.


    Highest ISR routine execution time (s): 135,230
    Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation


    Highest reported total ISR routine time (%): 0,235341
    Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation


    Total time spent in ISRs (%) 0,280384


    ISR count (execution time <250 s): 151486
    ISR count (execution time 250-500 s): 0
    ISR count (execution time 500-999 s): 0
    ISR count (execution time 1000-1999 s): 0
    ISR count (execution time 2000-3999 s): 0
    ISR count (execution time >=4000 s): 0




    _________________________________________________________________________________________________________
    REPORTED DPCs
    _________________________________________________________________________________________________________
    DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.


    Highest DPC routine execution time (s): 101062,620
    Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation


    Highest reported total DPC routine time (%): 4,216961
    Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation


    Total time spent in DPCs (%) 4,500411


    DPC count (execution time <250 s): 1056690
    DPC count (execution time 250-500 s): 0
    DPC count (execution time 500-999 s): 1
    DPC count (execution time 1000-1999 s): 0
    DPC count (execution time 2000-3999 s): 0
    DPC count (execution time >=4000 s): 0




    _________________________________________________________________________________________________________
    REPORTED HARD PAGEFAULTS
    _________________________________________________________________________________________________________
    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.




    Process with highest pagefault count: none


    Total number of hard pagefaults 0
    Hard pagefault count of hardest hit process: 0
    Highest hard pagefault resolution time (s): 0,0
    Total time spent in hard pagefaults (%): 0,0
    Number of processes hit: 0

    I overclocked my CPU to 4.0 Ghz. If there's additional info needed, please tell me so I can fix this mess
