  1. GIGABYTE GA-Z170MX-Gaming 5 Huge DPC Latency Spikes, Help!


    Hello,

    I recently upgraded my 5 year old PC and put together a new build utilizing the new 1151 chipset and following components:

    G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Intel Z170 Platform Desktop Memory

    Phanteks Enthoo Evolv Gray Aluminum / Steel mATX/ MicroATX Tower

    GIGABYTE G1 Gaming GA-Z170MX-Gaming 5 LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 Micro ATX Intel Motherboard

    i5 6600k

    EVGA Geforce GTX 760 SC ACX (from previous build)

    Windows 10 OS 64x

    Ever since upgrade, I have noticed the sound to intermittently hum/distort/crack while playing music, streaming videos, and especially gaming. I don't mind the occassional pop, but with gaming, this "DPC Lag" is significantly affecting performance dropping my FPS at times from 120FPS to 15FPS in games such as Dota 2, as well as Witcher 3 ( I have not had enough time to test other games). I've attempted various solutions, including all the useless support Windows 10 moderators have to offer (Run SFC /scannow does not work, nor does disabling audio devices).

    In addition, I have disabled all CPU power options and uninstalled Geforce drivers + network drivers only to get a slight decrease in lag as noted in the photos below which were taken after all solutions were attempted. I reinstalled Killer drivers as they were out of control with spikes, and that seemed to relieve some lag from those drivers. However, the directx and geforce drivers are way high and I can't figure out what I need to do. I've also been using the resolution timer application which also assists w/ reducing latency, but not to the point where all issues have been resolved (pictures below are with resolution timer on).

    I have contacted Gigabyte and they are legitimately useless. The worst support I have received in recent age. Did nothing to help me, only told me that they were unable to recreate the issue so they can't assist me.

    I am at wits end with this issue. I have spent over 30hours attempting to figure out how to solve this problem, and without success. I even reinstalled windows 10, and some issues.

    I will provide any additional information as requested and I appreciate any assistance .

    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. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 1:15:36 (h:mm:ss) on all processors.

    Reported CPU speed: 3504 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.

    ____________________________________________________________________________________________________ _____
    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.


    Process with highest pagefault count: dota2.exe


    Total number of hard pagefaults 13599
    Hard pagefault count of hardest hit process: 5107

  2. Extremely high DPC Latency from Directx Graphics Kernel since Anniversary Update.

    Same problem here. Updated to Anniversary yesterday (9/9/2016) and since then am getting DPC latency spikes of 5000-7000 us on dxgkrnl.sys when playing games. My games will literally freeze for about 0.5 seconds when this DPC spike occurs. The spike itself
    happens about every 3-5 minutes.

    Uninstalling and reinstalling graphics driver made no difference.

    Since you have a Gigabyte motherboard, if you have the Gigabyte supplied "EasyTune", uninstall it as it can cause noise, DPC spikes, dropouts, etc. I built a system with a Gigabyte motherboard and installed the EasyTune (V6 in my case). The PC was to be used for my recording studio and I was getting dropouts and noise. After conferring with a recording studio PC builder he found out I had installed EasyTune. He told me it was a known cause and as soon as I uninstalled it (and rebooted the PC) all my DPC spikes and dropouts went away.
