    [10v1703b15063 x64] DPC Spiking issues

    Hi, I'm currently having rather bad DPC latency's with a few things. Although, I don't actually have any audio pops or anything, though, my SSD usage spikes when a stutter happens. I particularly watch streams like on twitch and stream.me and they stop anywhere from two seconds to a full twenty and the disk like is spiking then it stop and then continues normally till the next one again. I have a decent connection 350Mbps down/15Mbps up. I use Chrome, But the same issue happens in firefox too. I get stutters under heavy disk load and heavy network loads, No amounts of settings seem to work, bios is set up. I have two network cards because i thought the killer one was doing it.

    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. 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 0:31:12 (h:mm:ss) on all processors.

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 350 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.


    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.






    _________________________________________________________________________________________________________
    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): 5483.553581
    Average measured interrupt to process latency (s): 12.426166

    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.

    Re: Windows 10 DPC Spiking issues

    Can't your company's IT people figure out the problem and fix it?

    Thanks for the amazing post.

    I don't work for a company.
    Enterprise was downloaded by my brothers link with his university when he attended there.
    I have a proper key. It is not a VLK or KMS.

    It is activated normally through windows activation

    Not sure if anyone's able to find out anything, or if they just don't know

    Would be grateful for any help.

    Re: [10v1703b15063 x64] DPC Spiking issues

    Latest official and stable bios is M4 2015-12-23; your logs say V22.5B5, 07/06/2016 (July 6th).
    Alternate your sticks (dimm0 ares, dimm1 ripjaws, dimm2 ares, dimm3 ripjaws).
    Increase your ram speed to 1866.
    "cmudaxp.sys is not digitally signed" found in dxdiag log. Try to use the tested and stable driver for it.

    It is the latest bios that was made for this board, however msi havent updated the boards page in a long time. It is Given when requested, from the staff over on MSI forums.
    But i'll try switching back.
    And i will try doing that, Though i think i did.

    The ripjaw ram is rated for 1600mhz, while the other 2133, If i increase the ram speed, wont that be overclocking the ripjaws?

    And yea. It's not signed, since it's a custom updated driver by the guy at maxedtech who does the Asus/cmedia drivers. UNi Xonar Drivers official page - MaxedTech
    However i will give the last driver from 2015 from asus a try.

    Thank you very much for your input.

    Re: [10v1703b15063 x64] DPC Spiking issues

    ~I ahve purchased the same sticks as the Ares, so they should come soon, so i wont be using mixed ram atleast.

    Will try it again once those come along. I will also do a no power battery cmos clear.
