[SOLVED] Very high DPC Latency by storport.sys and ndis.sys. FIX: I turned off MS driver verifier.

[yoghurt13]

I have audio cracking/dropouts and everything laggs.

I ran LatencyMon for about an hour



I reinstalled and updated the drivers, and the bios, nothing has changed. I'm running on windows 8.1.
I have xperf installed, but don't know what command to use to make a trace.

Is Windows 8.1 the original OS installed on your system?

Is BIOS updated?

 

[yoghurt13]

My motherboard is an ASUS M5A97 LE R2.0, I updated the BIOS from their site, BIOS Version 2501. And every driver was reinstalled from there too.
And if you mean by "Is Windows 8.1 the original OS installed" that the installation was from an 8.1 disc, yes it was.

Here are my computer specs if it helps:
ASUS M5A97 LE R2.0
AMD FX 6300
FSP Hexa 500W
Western Digital WD5000AAKX 500GB SATA3
Gigabyte HD7770 Ghz edition OC 1GB
Kingston HyperX 4GB DDR3 1600mhz CL10
(downclocked to 1333MhZ, CL9)
AMD Entertainment Edition 4GB 1333MhZ CL9

Hi,

avast! is a red flag here, especially considering MSFT Storage Port/Network Driver Interface Specification are the effected drivers. Remove it and see if it stops.

Regards,

Patrick

The problem still occurs even though Avast! is uninstalled.

Dear,

To properly troubleshoot issues with high/frequent DPCs/IRPs, we require a XPERF trace. Please follow these steps to generate one:

1. Download Windows Software Development Kit (SDK) for Windows and run the setup.
2. Select Windows Performance Toolkit feature (all the others can be unchecked) and proceed with the download/installation.
3. Once the installation finishes, open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
4. Type the following command, which will start tracing, in the Command Prompt window you just opened:
   

   xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER+IDLE_STATES -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular

   If you see a yellow warning "xperf: warning: This system is not fully configured for x64 stack tracing" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):
   
   Read More:

   1. Run the following command which will stop the tracing:
      

      xperf -stop

   2. Run the following command to enable stack tracing (by disabling Paging Executive):
      

      REG ADD "HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management" -v DisablePagingExecutive -d 0x1 -t REG_DWORD -f

   3. Reboot the computer
   4. Once computer reboots, proceed from the step #3
   If you see a red error "xperf: error: NT Kernel Logger: A device attached to the system is not functioning. (0x1f)" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):
   
   Read More:

   
   

   1. Run the following command to disable Driver Verifier, which causes the above error:
      

      verifier /reset

   2. Reboot the computer
   3. Once computer reboots, proceed from the step #3
   
   If you see a red error "xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7)", please do the following (otherwise, proceed to the step #5):
   
   Read More:

   
   Make sure you do not have any programs that capture ETW data already running. Some examples of these are:
   
   

   • Process Explorer
   • Process Hacker
   • Resource Monitor
   • Process Monitor
   • Latency Monitor
   • Another instance of XPERF or WPR
5. Perform some activities with your computer for few minutes, making sure the issues you reported are reproduced.
6. Run the following command, which will stop the tracing, in the command prompt window you already have opened:
   

   xperf -stop -d C:\CPU.etl

7. Compress file C:\CPU.etl
8. Upload the compressed file to a file sharing service (e.g. OneDrive or DropBox).
9. Share the download link here.

Thank you.

Thank you.

Let's start by disabling Driver Verifier:

1. Open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
2. Type the following command:
   

   VERIFIER /RESET

3. Reboot the computer
4. Check if the issues still persist and, in case they do, generate a new trace.

Thank you.

The DPC latency is now way lower than it was before, haven't experienced audio cracking/dropouts yet. But the hard pagefault is still high, and some lagg or system hang still occurs. But I think It's a faulty RAM or my old HDD, and I'm already going to upgrade those.


Will update in the next days if there are still some problems with DPC latency, and cracking/dropouts show up again.

And thank you guys for the help and care.
You're awesome guys.

I'm glad to hear it worked.

Let us know if the issues come back and don't forget to mark the topic as SOLVED if they don't.

 

[medievil]

had this issue myself, audio as very buzzy/clicking.. it would drop out for full seconds... disabled readyboot (Not ready boost) in win7 and now latency is near non existant. Still have a lot of hard page faults nut not as many as before...

Is anyone here willing to help me PLEASE, I'm going nuts. Here is my CPU.etl: http://puu.sh/lgnc0/d7ba03d0ef.rar

Hello, I have just built a new pc and I have been having latency issues with them randomly stopping my video/game for maybe a second or less ( not too bad but annoying). considering i built the PC less than a week ago, I believe something is wrong and I'm not too sure how to fix it. I read online about CPU throttling, not sure how that all works. I ran tests and most of them lead to my network and storport drivers. ( the biggest latency spikes) If someone could help it would be appreciated. (if i get a response I will post whatever you need to know) [specs, the cpu.etl, etc.] Thanks.

I'm glad to hear it worked.

could you pls help with my win10 pc? i tried to reset it (reinstall windows), install new network adapter and disabled existing one (normally i have internal intel network adapter), tried lots of other options. nothing helped. computer started normally, but it going slower and slower shortly. just in few hours 'interrupts' significantly overloads my pc. latency monitor shows the problem is in ndis.sys. actually, my problems started after march 2017 CU. before - all was fine. april CU helped a little, but may CU killed me again.

aceace, if you want someone to see your post on Windows 10 (this is the 7 and Vista section)
you need to start a NEW thread here

I´ve had this problem for a very long time and really tried everything. I clearly can't fix it with drivers. The issue does not exist if i completely disable my network device and live with no internet on my pc.. which is not really possible. Its not possible to disable driver verifier either. When i run it to reset it it says the settting have not been changed. And thats it. The stutter is so severe my mouse hangs around the screen for almost a full second quite often before moving again. Sometimes repeadetly. The sound stutters too and obviously playing games, listening to music, watching videos is all pretty unbarable. Bios update useless. All windows 10 versions have the problem. After 5-6 Pc resets and reinstalls I gave up on that. Ive tried installing windows 7 to finally get a working pc again but when i try that the mouse and keyboard stop working in the middle of the install process and im just stuck there. And i could not find a solution for that either. Ive used surely more than 100 hours on this instaling. reinstalling. deleting, reading forums, etc. Reinstalling all my programs and devices, backing up all my documents and games.. downloading things for days again and again and again. Even on a full factory windows 10 with nothing else installed a completely empty windows 10 this problem occurs. At least my laptop which also has windows 10 works fine. I dont understand this. I had the same issue with my old desktop pc, now ive got a new one with nearly the entire hardware being new. The only things still the same are the PSU and the WIFI card. I´ve run Lateny mon too ofc. It is primarily ndis.sys i get up to 120ms latency. Mostly 86 though. My PC is quite high end (a waste of money since as you know it really doesnt work) .. so unsurprinsingly the stutter has nothing to do with system load which on all ends can be as low as 5% and still stutter like hell just moving the mouse around.

AMD?
In the device manager, find "ATA / ATAPI IDE Controllers", select "AMD Sata controller" and disable it.

Omg, thank you so much!

I found this thread total by accident, and i had this issue with my pc for some time now, and disabling the AMD Sata controller solved it. Idk how, but it works now, no more stuttering.

Well i´ve 4x AMD Sata Controllers showed in Device Manager, should i disable them all?
