    Latency problems after upgrade to version 1803


    Hi,

    After the upgrade last spring to version 1803 my PC began to experience latency issues. Audio popping, lagging & stuttering. I have since installed many different OS’s (Linux too) on this old Dell Studio desktop (x58 chipset, i7-950, SSD) & can verify the problem started with 1803. I am currently on 1709 & the PC is running great. I have deferred feature updates for 365 days & found the WU mini tool, much thanks to the folks who post here.

    Support for version 1709 runs thru spring of 2019. Hoping I can resolve this before then.

    Here’s some of Latencymon while on version 1803. USBPORT.SYS & STORPORT.SYS look like the culprits:
    Code:
    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.

    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.

    I installed 1803 again (1809 first, just in case the latency issue had been fixed) & then installed the Intel chipset drivers: INF Update Utility - Primarily for Intel® 6, 5, 4, 3, 900 Series Chipsets. Received message stating install successful but still the latency issues persist.

    Honestly have no idea what I’m doing here & hoping someone can point me in the right direction. Southbridge on X58 is ICH10R, where I’m assuming the problem resides. Did Intel/Microsoft finally drop support in 1803?

    Latency problems after upgrade to version 1803-chipset.png


    Found year old threads regarding RST ICH10R driver & BSOD on the Intel forums. No BSOD here & those posts occurred in the Creators Update, or the one I’m on now.
    Way back when adding the SSD (Win7) I removed RST (or Matrix Storage Manager), seems it wasn’t necessary. Did just install them on both versions 1803 & 1809 tho, made no difference regarding latency. Don’t think those threads apply to me…

    Am I not understanding the drivers at fault?

    Hey, thanks for any help

    Hi, those two reports are relatively common for LatencyMon.

    1. When MS delivers a new build, it comes with a set of drivers. That, from the lowest level, may differ from those delivered with the preceding build. Thus people upgrading their build may suddenly find they encounter unexpected issues.

    It is possible, therefore, that if you could identify a driver difference between that used in 1709 and in 1803, you could reuse the driver from 1709 in build 1803. There is one thread where this was done.

    This is very far from ideal of course.

    2. Is your BIOS up to date?

    3. For further analysis, you can use the Windows Performance Recorder, available for download from MS (search the forum for that for threads with examples of its use). This was used in the thread I'm thinking of, which took several iterations back and forth between 1709 and 1803 to identify the driver, if I recall.

    How old is your PC?

    Note that there are (quite different) known issues with 1803, particularly with respect to changing default apps (e.g. for txt- like file types), apparently caused by one particular update.

    Hi dalchina,

    Yes, I have the latest & greatest BIOS update from 2009.

    Purchased this Dell Studio XPS 435MT in 2009 with Vista Ultimate. Came with a free upgrade to Windows 7 & then MS gave us another to Win 10. Very pleased with this purchase so far.

    I do have the Windows Performance analyzer & debugger portions of SDK installed & did find my way to Fernando's BIOS modding forum. Sure I must have come across that topic... Now I see his name everywhere.

    There are only two options in my BIOS, ATA & RAID. In order to get AHCI enabled it must be in RAID. I have no RAID volumes defined.
    I'll learn how to use WPA/R & figure out what the driver difference is.

    Thanks, sure I'll be back.

    Hi,

    So, apparently the SATA RAID Controller driver v15.44.0.1010 introduced in version 1803 was the culprit. Driver v13.44.0.1026 from 1709 is good.
    Thanks to the great folks at win-raid dot com I installed an earlier driver version = 13.2.8.1002.

    Currently on Windows 10 version 1809 & PC is running well, experiencing no latency issues

    Thank you

    Great you've identified it. It's unfortunate that there doesn't seem to be any easy way to do that - and also that MS occasionally delivers inappropriate drivers.

    Report on Feedback Hub... and you'll need to block any update of that driver.

    Hi dalchina,

    I've updated my feedback. These forums are great!

    Thanks for your assistance.

    Hey guys it seems like on and off since the 1809 update I've been getting a lot of audio stuttering and popping, this also significantly slows down my Overwatch game (even tho I have 140+ FPS the whole time), I also get instances where my mouse will be unresponsive for a few seconds.

    I looked into DPC and latency and it shows USBPORT.sys or something was the issue. I'm also wondering if it could be the same issue with RAID/storage driver you had since I use to have a RAID setup and now I don't since a disk died. I can't figure out how to download or get a copy of the older 1709 Intel SATA drivers, can you tell me how you did it?

    Thanks a ton.

    Thank you for solving my problem!


    Dog Park,
    I have the same computer and the same problem and your fix worked for me too. I used a slightly different driver from Intel's web site because they didn't have the one you mentioned and I had a little difficulty navigating the web site you used. I had to use the "I have a disk" option to get Windows to accept the old driver but now that audio/video stutter is gone!

    I can't believe it took me over a year to find the right solution, I tried all kinds of crazy suggestions to fix this. It's a miracle I didn't blow the computer up with all the stuff others had me doing.

    Many, many thanks!

    Hi Atomizer,
    I'm helped so much on this forum glad to hear I provided some.


    Hey MMAniac911,
    Short story I ended up installing driver Intel RST AHCI/RAID driver version 11.2.0.1006, Dated 5/30/2012 on my I7-950 Dell XPS. Have been on it for several months now - no problems.
    You can find it here:
    Intel's RST/RST(e) AHCI/RAID Drivers - under "Newest/best Intel AHCI and RAID Driver" you will find "Classical" Intel RST Drivers and their RST Software:" wherein resides ">64bit Intel RST AHCI/RAID Driver v11.2.0.1006 WHQL<. It is digitally signed by MS, makes it easy to install. Don't download the Drivers & Software Set, just the driver. The software set is only needed for those who use RAID, imo.

    I suppose you could download it from Intel: Intel® Rapid Storage Technology (AHCI) for Windows XP*/Vista* on Intel® 6 Series Chipset-Based Desktop Boards

    Fernando at WIN-RAID dot com modded for me driver (actually the .inf file, not the driver itself) "Universal 64bit Intel RST AHCI & RAID Driver v13.44.0.1026 for Win10 x64 mod+signed by Fernando.rar" (from 1709) & my PC would Not enter sleep mode in WinX versions 1803 or 1809. Same for driver "original 64bit Intel RSTe RAID driver v13.44.0.1026".
    Generated the following messages in the log:
    Event ID: 26 - \SystemRoot\System32\Drivers\iaStorAV.sys failed to load
    &
    Event ID:45 - The system could not sucessfully load the crash dump driver.

    You can read all about it if you like by clicking this link.
    No problems sleeping with 11.2.0.1006.
