    [W7SP1 x64] High Latency, DPC/Pagefault Time Issues

    Hello, I've got an issue with a machine I built for myself that for the better part of a month I have not been able to pinpoint exactly what is going wrong. In games (specifically noticable in Fallout 4) I get Micro stuttering (visual). I started looking into what could cause this issue and ended up looking into DPC's from things like my video card drivers ect. I ran LatencyMon and found something I don't have a clue how to interpret. This is what I get just from loading firefox, or any application I have. There is a noticeable pause, the highest measured interrupt to process latency rises to whats seen here, and the program loads. The pagefault resolution time sits in the yellow at idle, and skyrockets once I load something like firefox along with the pause before it finishes loading.

    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 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  0:42:28  (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.
    
    Highest measured interrupt to process latency (s):   2629.324871
    Average measured interrupt to process latency (s):   1.527590

     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.

Having tried all I found (disable HPET, disable C-states, disable intergrated audio/network cards (in bios and windows) and even running with intergrated graphics) the issues are still present.

    Any suggestions would be appreciated.

    Re: High Latency, DPC/Pagefault Time Issues

    Hi Sytron.

    Would you try these steps?

    Preamble

    In case you don't know how to open an elevated command prompt in windows 7, you can use one of these three methods:
    • click start, all programs, accessories, right-click the command prompt in the list and click run as administrator, click yes on the user account control window that should appear
    • click start, type cmd in the searchbox, right-click the cmd in the list of results and click run as administrator, click yes on the user account control window that should appear
    • click start, type cmd in the searchbox, press and keep pressed ctrl + shift Keys on your keyboard, then press enter, click yes on the user account control window that should appear


    1. Left-click on Start, type directly msconfig, press enter.
      Is the radio button on normal startup?
    2. Advanced disk cleanup with cleanmgr:
      • Open an elevated command prompt
      • Type cleanmgr /sageset:1 and press enter.
      • Select all the options, or leave unticked the ones you prefer.
      • Type cleanmgr /sagerun:1 and press enter
      • Let it work until it finishes.

    3. Launch this command from an elevated command prompt:
      sfc /scannow
      If you get the following message:
      Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log
      Read Windows Update Forum Posting Instructions (click) and provide the necessary (and missing) informations to the experts. I.e., you should:
      • export and zip/compress the entire CBS folder on your desktop
      • open a new topic in the windows update sub-forum (in sysnative.com)
      • attach that zipped file to that new topic

      If the CBS compressed folder will be too large, you can check the second post on that thread (to use the sfcfix tool with a script) or you can use a (possibly fast) web service like MS OneDrive, Google Drive, DropBox, Box, Mega, Apple iCloud, Amazon Cloud Drive, and so forth...
      Instead if you get the following messages, go to the next step:
      Windows Resource Protection did not find any integrity violations
      Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log
    4. Defragment your system drive (using windows default defragmenter). Steps:
      • Open an elevated command prompt
      • Type defrag c: /h and press enter
      • Wait until it finishes

    5. Check your system partition, then post the result here. Steps:
      • Open an elevated command prompt.
      • Type chkdsk c: /b and press enter.
      • You'll get:
        The type of the file system is NTFS.
        Cannot lock current drive.
        Chkdsk cannot run because the volume is in use by another
        process. Would you like to schedule this volume to be
        checked the next time the system restarts? (Y/N)
      • Type Y and press enter.
      • Then restart/reboot and wait until it finishes this check.
      • To find chkdsk result:
        • Open an elevated command prompt
        • Copy/paste this command and press enter:
          Code:
          wevtutil qe application /c:1 /rd:true  /f:text /q:"*[System[Provider[(@Name='Microsoft-Windows-Wininit')]]]" > "%userprofile%\desktop\ChkDskLOG.txt" & notepad "%userprofile%\desktop\ChkDskLOG.txt"
        • It should create chkdsklog.txt on your desktop and open it: paste its content here.
        • If the command won't work, type eventvwr, press enter, in the event viewer window double-left-click Windows Logs to expand it, left-click Application, double-left-click the information event with source wininit, copy its content and post it here.

    Other: I've also ran this machine outside of a case on my wood desk to rule out ground/short/static issues. Also changed all minor cables such as DVI/HDMI/SATA with no improvment. Tried using 3 different displays as well.

    I've Tried All that I can to eliminate any thing I myself may have caused. Thanks for your time!

    Re: High Latency, DPC/Pagefault Time Issues

    Your MB should support DRAM Frequency until 2400MHz, without overclocking.
    Intel declares DDR4-2133/2400 @ 1.35V, supported by your cpu (without overclocking, I suppose).
    Speccy reports 1500.0 MHz (i.e. it's 3000 right now), and XMP-2998 --- 1499MHz --- 15-17-17-35 --- Voltage 1.350V.
    Then I saw (under motherboard): Voltage CPU CORE: 1.212V --- MEMORY CONTROLLER: 2.040V.
    I'm not sure if that value should be 1.350 (or 1.200, with other RAM profiles).

    It seems your MB manufacturer tested the RAM sticks (that model is present on their QVL) with these values: 15-17-17-35 1.35 2133.
    It also seems they tested the sticks on all the four slots.

    In the end, I'd try first to modify the XMP profile in your BIOS settings to jedec 7 or 8 (see speccy), i.e. I'd set the DRAM Frequency to 2133.

    Ok having done that, still getting the same results. I also looked at lowering the memory controller voltage but 1.94 is as low as it goes.

    Re: High Latency, DPC/Pagefault Time Issues

    I forgot you modified some settings in your BIOS.
    Load the optimized defaults in your BIOS, then re-check the DRAM frequency value.
    If it choose 3000, set it to 2133.

    Another thing you can try is to unmount every piece of your hardware, (remove dust if present, and apply new thermal compound on your CPU if necessary), then re-mount it.

    Re: High Latency, DPC/Pagefault Time Issues

    Loaded the optimized defaults, checked the DRAM frequency and then reduced it from 3000 to 2133. No change
    Forgot to mention when I was trying different videocard/SSD/PSU combinations on my desk I also re-did the thermal paste on my CPU. Re-mounted everything (cooler, gpu, ram, SSD, PSU ect) once I put my motherboard back into the case I'm using. Thanks again for all the time your taking trying to help me find whats wrong here. I really appreciate it!

    Can't seem to find the edit button, anyways I'm noticing more and more times when even scrolling in firefox or steam that my machine seems to freeze in the midst of scrolling then continue on as normal. It's as though if I do something it has to "wake up" taking about 2-3 seconds before it responds to my actions. My mouse cursor is unaffected during these freeze's, reminds me of the days of using dial-up and playing first person shooters online with a 400ms+ latency.

    Re: High Latency, DPC/Pagefault Time Issues

    Update at last, I found something that may be of use to others. Though the issue I've been chasing (visual stutter) seems to persist.

    I did a fresh format, installed Win10 Pro, switched over to a corsair ForceMP 500 M2 SSD, nothing changed. Looking further I found out something about 7th gen intel chips that I never knew about. A feature called core parking. I used a program to "unpark" the cores that had been parked. That solved the noticeable pause that I would get when loading up an application like Firefox or even scrolling down a page after sitting idle. DPC issues seem to be gone along with the high pagefaults.

    However the overall issue I've been chasing is still present and hasn't changed. I've tried various games, emulators, all of which have the same stuttering. Running Dolphin a Gamecube emulator that my old 3770k used to handle just fine, FPS stays at 60 but at random times the video stutters.

    Is it possible my CPU is faulty? The motherboard/cpu are the only things I haven't been able to switch out and A/B compare. I checked the board for blown/bulged caps and found none. The cpu socket *looks* fine so far as I was able to tell. No burnt smells of any kind either.
