  5. Disable Core Parking & CPU Throttling

    Intel processors feature CPU power management abilities that dynamically change clock speeds and sleep states. These changes can adversely affect real time audio. If you are experiencing pops and clicks then we recommend that you disable these features.
    Many systems will have setup options that allow you to turn off certain power management features. Please consult your motherboard or system manual for help with making any changes in your BIOS / UEFI setup utility.
    By disabling the following features, your system will run at a constant clock speed and will not halt individual cores:

    • Intel SpeedStep (or EIST)

    • Intel Turbo Boost (or Turbo Mode)

    • C-State Control (or C1E, C3, C6, C7)

  6. If the problem persists, please generate a Windows system information file and contact Customer Support by submitting a new support request. Follow the directions below to generate a Windows system information file:

    Go To: Start -> Run
    Type "msinfo32.exe" and press enter.
    Go To: File -> Save to save the file. 

    Please attach this '.nfo' file when you submit your support request.
