    _________________________________________________________________________________________________________
    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 0:05:00 (h:mm:ss) on all processors.

    Hardware: B350GT5, BIOSTAR Group
    CPU: AuthenticAMD AMD Ryzen 7 1700 Eight-Core Processor
    Logical processors: 16
    Processor groups: 1
    RAM: 16337 MB total




    _________________________________________________________________________________________________________
    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 2994.0 MHz
    Measured CPU speed: 5216.0 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.




    _________________________________________________________________________________________________________
    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): 2288.492290
    Average measured interrupt to process latency (s): 5.657487


    Highest measured interrupt to DPC latency (s): 2284.730572
    Average measured interrupt to DPC latency (s): 2.122862




    _________________________________________________________________________________________________________
    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): 72.064128
    Driver with highest ISR routine execution time: Wdf01000.sys - 内核模式驱动程序框架运行时, Microsoft Corporation


    Highest reported total ISR routine time (%): 0.003278
    Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation


    Total time spent in ISRs (%) 0.005762


    ISR count (execution time <250 s): 150016
    ISR count (execution time 250-500 s): 0
    ISR count (execution time 500-999 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): 100482.224449
    Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

    _________________________________________________________________________________________________________
    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

    Re: High DPC by storport.sys

    Hi. . .

    storport.sys is a Microsoft storage driver.

    Driver Reference Table - storport.sys

    If you have an Internet Security Suite (Norton, KIS, McAfee, etc...) installed - remove it - Uninstallers (removal tools) for common Windows antivirus softwareESET Knowledgebase

    Update your audio drivers

    Make sure BIOS is up to date.

    Re: High DPC by storport.sys

    Hi flakes.

    Please read POSTING INSTRUCTIONS for DPC/ISR latency, stuttering, cracks/pops (click).
    Then open your own topic, providing those logs and info.
