    Question high dpc latency with my new computer

    i bought i7 and msi z170 motherboard, g skil ram
    but dpc latency is too high(over 1000um)
    i tried almost know solution but didn't work

    i need your help

    which diagnostic program i have to use for your help?

    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 0:15:23 (h:mm:ss) on all processors.

    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.

    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.


    NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

    Re: high dpc latency with my new computer

    Hi again

    Sorry for the long wait for a reply: I've had a surge in my repair business & my free time vanished for a while....

    It looks like you are suffering a lot of the same issues that you experienced with your previous build. Nice upgrades with the advanced motherboard and the i7.

    Native Instruments
    For a first thing to investigate: check over at Native Instruments for the newest versions of their drivers for the Guitar Rig program, and for your audio interface (I'll guess it's a Kontrol model). For the audio interface, check for both updated drivers and for updated firmware. Native Instruments has been pretty good about trying to get their gear to work better in Windows 10 ... quite a lot of the drivers and firmware have quite recent versions.
    Support

    Latency Monitor 6.50 or newer
    To give us a look at your latest numbers, use Latency Monitor to produce a graph of the latencies (DPC counts), interrupts (ISR counts), and hard pagefault counts. Also see if you can produce a chart for each type (latencies, interrupts, hard pagefaults) that lists your processes with the highest counts at the top of the list. [So -- that would be one graph and three chart/lists of processes].

    Also make sure that the version of Latency Monitor that you are using is the most recent. Versions from 6.50 and newer are now compatible with Windows 10 (earlier versions produce incorrect results on Windows 10, due to all the changes).

    And here are some other tips that I've been collecting, as folks fight the battles against audio/video performance in Windows 10:

    SSDs
    Since SSDs are dropping in price and growing in size, I've lately been recommending that the worst-offending audio-pop suffering programs/games be installed onto the SSD. Windows doesn't take up all that much room, and neither do a few games (you can still keep "saved games" and other non-demanding software installed to a larger "spinning" hard drive, along with your photo, music, and video collections).

    SATA ports
    Some users who haven't seen any improvement by means of updating drivers have had success by altering their SATA port usage. A recent thread here concerns a system where the audio stuttering was helped by unplugging a DVD SATA drive (...and our tech Cluberti was nice enough to help explain why) ... The last few posts are where you will see mention of the SATA ports (and the nature of USB polling & the effect on latencies) .... Here's a link to that thread:
    High DPC Latency or pagefaults - Fresh Install - USBPORT.SYS and others.

    Hard Pagefaults
    For the high hard pagefaults, it can help to:
    1) Limit startup processes that you don't need
    2) Limit Windows-Updates file-sharing (in Settings > Updates and security > Windows Update > Advanced Options > Choose how updates are delivered > turn off "updates from more than one place" - that will limit unnecessary background network activity)
    3) Limit the amount of "telemetry" (data sent to Microsoft ... choose the "Basic" option in Settings > Privacy > Feedback & Diagnostics ... and you can try "Never" as your "Feedback Frequency" while testing your latency issues)
    4) Limit any Notifications that you don't need or want (Settings > System > Notifications & actions
    5) Turn off "Live" tiles on your Start Menu (to limit unnecessary background updating of any information you don't want or need)
    6) Uninstall any Windows "Universal" apps that you don't want or need (Settings > System > Apps & features -- click the app you wish to uninstall) ... and for those that you don't want, but can't uninstall (some of the built-in apps) - you can still keep them from starting unwanted services (in Control Panel > Administrative Tools > Services) or startup modules (in Task Manager > Startup tab)

    Drivers
    Even if you've updated most drivers ---> Hunt for updates at least once a week or more, until your audio/video issues are resolved. The driver landscape for Windows 10 is changing daily.... A better driver can be the difference between glitchy audio/video or smooth as silk audio/video.

    Antivirus
    Some users find that certain modules of their antivirus program can have a rough affect on their audio quality. For some, it is especially noticeable when using the third-party firewall. You can try reverting to using just the Windows firewall, or to turn off a feature in the third-party firewall that blocks port scans (since most routers/modems/gateways have built-in port scanning blocking, it doesn't necessarily lower your defenses, since your hardware provides the service).

    Virtual Memory & a large set range
    Since some computers experience the audio/video glitching during gaming, and Latency Monitor graphs often point to high hard pagefaults as a contributing factor (as in the pagefault tips above), I like to recommend testing things with the Virtual Memory settings for your computer manually set to a generous range (generally, with the lowest value the amount of your total installed physical system memory, and the highest value twice that number). This is an overly large range = but it can prove useful for testing. [after testing, the upper range could be lowered to one and a half times the physical memory total]... The reason for the large set range is that some games are infamous for memory leaks, and the large range might give you a better chance of surviving the memory trouble caused by the game with the memory leak.

    __________

    I'll be out doing repairs in the field most of the next few days, but I should have a chance in the late hours to see how you're doing.

    Cheers

    6) Uninstall any Windows "Universal" apps that you don't want or need (Settings > System > Apps & features -- click the app you wish to uninstall) ... and for those that you don't want, but can't uninstall (some of the built-in apps) - you can still keep them from starting unwanted services (in Control Panel > Administrative Tools > Services) or startup modules (in Task Manager > Startup tab)

    Antivirus
    Some users find that certain modules of their antivirus program can have a rough affect on their audio quality. For some, it is especially noticeable when using the third-party firewall. You can try reverting to using just the Windows firewall, or to turn off a feature in the third-party firewall that blocks port scans (since most routers/modems/gateways have built-in port scanning blocking, it doesn't necessarily lower your defenses, since your hardware provides the service).

    Virtual Memory & a large set range
    Since some computers experience the audio/video glitching during gaming, and Latency Monitor graphs often point to high hard pagefaults as a contributing factor (as in the pagefault tips above), I like to recommend testing things with the Virtual Memory settings for your computer manually set to a generous range (generally, with the lowest value the amount of your total installed physical system memory, and the highest value twice that number). This is an overly large range = but it can prove useful for testing. [after testing, the upper range could be lowered to one and a half times the physical memory total]... The reason for the large set range is that some games are infamous for memory leaks, and the large range might give you a better chance of surviving the memory trouble caused by the game with the memory leak.
    -> oh...i forgot about the windows's virtual mem, i'll try this

    Re: high dpc latency with my new computer

    Hi again

    Just wanted to let you know I haven't forgotten you, but I've been out fixing things & haven't had as much time here lately. I have you on my list of "things to do" for tomorrow ... so I should have some feedback for you by 3 a.m. or so Saturday.

    I'd clone myself if I could.

    Re: high dpc latency with my new computer

    Hi again


    Well djseltus, you have managed to send a file that may have set a record for being far too large to analyze. The file you sent is over 2 GB unzipped. I don't have any tools that could analyze that without crashing. Let's try another tactic.

    Try downloading & running the SysNative info-gathering app. All the instructions for downloading it and running it are in the link I'll post here in this thread. It will gather files that show your error logs, drivers, startup processes, etc. Very time-consuming to look through, but can provide clues in hard-to-solve systems issues such as you have. There are other tools and other recommendations in the link, but for now I'm mostly interested in a look at the app's info collection. You had tried Driver Verifier previously, if you've tried it again - remember that you need to turn it off after testing (because it can be a source of instability & has enough overhead to cause performance issues as well. Here's the link to the info-gathering app (post the results here in this thread, since yours is an audio/video issue rather than BSOD issue) ...
    Blue Screen of Death (BSOD) Posting Instructions - Windows 10, 8.1, 8, 7 + Vista

    While you wait for me to analyse those files:
    Diagnostics
    Please run some system diagnostics. Test the memory with the latest version of MemTest86, and test the hard drives with diagnostics from the hard drive manufacturers (especially the SSD).

    Crossfire & Power Supply
    In your previous build, you'd mentioned both a Radeon R9 270x and a Radeon R9 280. Are you using just the R9 280? Or do you have both installed, and linked in a "crossfire" configuration? If you are running both, I'd recommend going to a 750w power supply, up from the current 650w. The Radeons are real power-guzzlers. If you are only using one card, the 650w is probably OK.... assuming it is a high-quality brand (I'm leery of lesser brands boasting 80 bronze)....

    USB
    Check in Device Manager & see if you have the ASMedia USB 3.1 driver. If you do, uninstall it & try a generic. We've seen it cause trouble in the past, and it came up recently (yet again) in another audio-issue thread here in the forum.

    I'll check back for the info collection files. Till then ... let us know if you discover anything new.

    Re: high dpc latency with my new computer

    Hey.. looks like Win 10 isn't out of the HIGH dpc latency water yet .
    I basically had no way to fix this, so I had only one choice: DOWNGRADE to win 8.1 . Since you're also doing audio, I'll take a looksie to see if you can work around it..

    this was pretty much different with old one
    maybe you can read test files with this tool

    Re: high dpc latency with my new computer

    Win 8.1 has DPC latency too, but not nearly as bad as Win 10 for me. Either of them don't have great support for nvidia drivers, the Nvidia team actually admitted that haven't solved it yet.
    But I'm not sure what video card you are using? Many network cards and soundcards aren't optimized yet too.

    With WIn 7, there was no such thing as DPC latency on my end.

    Re: high dpc latency with my new computer

    Hi again

    Thanks for sending the latest files.

    It looks like your system's default language is something other than English. This causes your system and error logs to be in the default language, rather than English. If it were French, Spanish, or Italian I might be able to figure them out (took some language classes in college). But I'm afraid I'm not as familiar with the character-based languages of Asia. If you could add English as a language to your system, and then change to it when running the SysNative info-collecting app: that should cause the logs to use English. Then you can simply switch back to your usual default language. You can keep many different languages installed on a Windows 10 PC, and fairly easily switch between them.

    So - try the language switch long enough to generate an English batch of logs, post them here, and we'll have a look.
    _______________

    In the meantime ...
    I was able to see that you are running an "Insider" version of Windows 10. I recommend reverting to the officially released public version. Since we are troubleshooting, we don't want to fuss with beta versions.
    _______________

    Regarding the traces: I too have the latest version of the Windows 10 Performance Analyzer. The reason that I couldn't read your trace on my computer was that it was so huge (2 GB is far too large for a simple computer like mine to analyze ... for business, I use a modest little 4 GB total system memory laptop).
    _______________

    You mention that you didn't have latency issues in Windows 7, but have had latency issues in Windows 8.1 and Windows 10. Any reason not to run Windows 7 for now, and wait to upgrade to Windows 10 later (if you upgrade the hardware to Windows 10, it should keep it's "digital entitlement" to Windows 10 for the future. You could upgrade, when ready, for no extra cost. You'd simply run Windows 7 until Windows 10 works better with audio.

    I'll stay tuned...

    Re: high dpc latency with my new computer

    i'll install eng lang pack then try it again
    _____________
    i installed it recently because of some reasons and it has just the same dpc latency value and drivers with high latency count
    i submitted that report for confirmation of 'did i perform it right?'
    and nevermind about it. as i said before, i'll clean install os soon
    _____________

    one of two test files is only 500mb even after unzip
    maybe you can run this one on your laptop


    _____________
    i didn't test win7 on this computer yet. and i don't want to because as you know windows 7 dosen't support many uefi features so it runs on csm legacy mode
    so i can't use fast boot and many more, plus even some chipsets of my z170 mother board dosen't support win7 (
    well.. then i'll try it for test though..

    and my old fx8300 computer had an issue with win7 too
