Hi,

I hope someone can help me !

I have high latency readings for NDIS 6.20 and ataport.sys my specs are:

Windows 7 professional 64
No wireless card
Killer e2200 gigabit Ethernet controller
MSI G-45 Gaming motherboard
No third party firewall or anti virus

I have heard bad things about this Ethernet adaptor but it is built into the board so is there any way to stop the high latency ? Would it be causing problems with the ataport.sys also or is this a separate issue?

Many thanks !

I've had a lot of issues with my motherboard (asus maximus viii hero) but the most annoying one appears to be related to intel's ethernet adapter I219V.

Basically whenever i download something or use the internet for a long time i would get huge sound stuttering issues. They appear ONLY while internet connection is active and only while something is downloading (while watching and caching youtube videos for example).

The issue gets progressively worse the longer the internet is active as well and after a few hours and heavy usage i get 14ms delays on ndis.sys and sometimes tcpip.sys too.

I've tried contacting Asus support four times to no avail - they confirmed that this is an issue related to intel's adapter and windows 10 and recommended me to buy additional cheap lan card (what's the point of having a gaming motherboard i wonder?), i've also tried writing in intel's forums which contain at least 14 pages of complaints related to this issue but apart from some shady guy claiming to be an engineer we didn't get any response and the only thing he recommended was to contact the manufacturer.

I've also set my CPU performance to 100% and disabled speedstep in BIOS which didn't help at all. I also keep my bios and drivers relevant but it doesn't make any difference. While running sfc /scannow i had not encountered any issues either.

Another solution seems to be to install much older drivers which do not produce this issue but unfortunately it doesn't work for me since th... Read more

I was wondering if anyone found a solution for a high latency issue with intel's ethernet drivers and windows 10 which results in ndis.sys driver producing stuttering? It's a known issue which became worse with the release of windows 10 and apparently the only solution so far is to use older drivers which only work on windows 7 and 8.

Basically whenever i download something big and or use the internet connection for several hours the ethernet adapter starts producing latency spikes. I've contacted motherboard support 4 times and been told that this is an intel's issue or that i should buy additional cheap lan card or just wait for a fix but and im kinda tired of waiting. Also intel never properly responded or confirmed this issue either, apart some guy claiming to be an "engineer" and writing a couple of messages on intel's forums basically saying "this is not our issue go and talk to motherboard's manufacturer".

Hi,
Over the last few weeks I've noticed that I was getting audio studders and distortions. I ran a few programs and identified that ndis.sys had been running at a latency of about 86 ms. When I disable the PCI network adapter driver, the latency spikes stops
and audio/video returns to working order. Obviously running without internet is not a solution.
I updated the bios and all drivers, still no fix. I ran Windows Defender and Malwarebytes but nothing was detected. 
I downloaded the Windows Assessment and Development Kit by following the Wiki. Here is the WPA file that was returned:

hello all,

I am a professional audio designer and I use an external audio card for performance playback,
however, recently, I have started to have problems with audio dropouts because of this service.
I understand that it is a networking driver, but I have never had issues with it until recently. What
is more confusing is that the problem persists when I disconnect from a network and it is not in use.
I am puzzled by this and since I do a lot of work in a mobile environment with my laptop, it is
driving me up the wall. I cannot find a solution. It is a necessary driver and I understand that this same driver has caused a lot of problems including bsod's for people.

Why would it start doing this "out of nowhere"? also, I performed a full factory default restore on the machine including service pack and all updates. ndis.sys STILL runs at an average of 3ms.

Any idea on what can cause this and how to fix this?

*I know this has been threaded all throughout the internet on many different websites and I think we need too get to the bottom of this.

As usual, this is a problem that happens when I use Windows 7 64-bit. (I think it's happened to 32-bit users as well, and I read some cases with XP users... but as for me when I had XP, I never experienced any of this).

In my case, I need to run Windows 7 due to the fact that I have 8 gigs of ram in my system and Windows XP 64-bit has basically no drivers developed for it that are in working condition. My specs are: ASUS M4A785-M mobo, AMD Athlon II X4 620 Processor 2.60GHz, 8.00 GB of RAM, Realtek PCIe GBE Family Controller, XFX AMD Radeon HD 6950 2048mb, Steinberg CI1 Audio Interface.

Basically when I disable the network adapter, everything works smoothly, music, games, video files, etc. but once it's on, my LatencyMon shows NDIS.sys running at 33ms where as everything is in the microseconds more or less. Although at the very moment netbt.sys is running at 2ms (I don't know if that's bad or good) but I definitly notice when the network adapter is disable, I get no audio-dropouts/static/distortion. Is there any way of fixing this issue that anyone has come up with? I tried a whole bunch of different methods including updating drivers, uninstalling applications one by one, disabling/enabling different options in control pannel, power management etc. NOTHING but disabling my network adapter does anything so I know that is the problem...

For more than a year now i've been trying to get rid of latency issues on my pc. According to latencymon they appear due to ndis.sys driver spikes which tend to appear at random intervals when i browse and refresh pages or download something. Remarkably though they do not appear while i play online or at least i do not notice them.

Those spikes produce noticeable sound distortions/pops when watching movies or videos on youtube.

Recently i've made a complete fresh reinstallation of windows 10 and updated it to 1607 but unfortunately the stutter is still there.

I've also been talking to Asus support and writing on Intel's forums, and while Asus keeps shifting blame on Intel they in return keep insisting that there are no issue's with their network devices. I've also tried different drivers and recommendations like disabling "interrupt moderation" or "offload/upload" settings in network driver settings, or removing wan miniport drivers.

There are also multiple threads about this issue on Intel's forums but unfortunately they are all related to older network devices and the usual recommendation is to install older drivers which aren't compatible with my device.

I've been hoping that someone might have figured it out over the passed year or might be interested enough to help me fix this issue since it's probably the only one i've got left with my new rig and it's driving me crazy.

I have a question about ping times, latency, and jitter.

I believe I understand the concept of jitter. If I ping www.google.com, and get some results of 10ms and others of 100ms, my jitter is 90ms; right?

If that's true, here's the question I have:

Is it ever preferable to have a connection with higher latency but less jitter? For instance, would it ever be better to have a 100ms latency with zero jitter than it would be to have latency that fluctuates from 10ms to 100ms?

One possible application I could think of would be something like VoIP or videoconferencing, where (perhaps) you would prefer consistency, even if it means higher overall ping times.

Over the past week I have had serious audio/video stutter every few minutes for a second or two. It wasn't until last night I ran LatencyMon and discovered the drivers that have caused the issue. I have tried doing multiple diagnostic tests and many of them have come clean. I suppose that to provide more information on what has occurred, I will provide a timeline.

1. Experienced a BSOD right before shut-down due to "Page Fault Found In A Non Paged Area."
2. On the next boot, the keyboard plugged into one of my USB3 ports was not working, so I unplugged it and plugged it back in and it worked again.
2. It was after this BSOD that I began to experience the audio/video stutter issues.
3. Attempted to do tests on multiple pieces of hardware including CPU, RAM, and my various HDs. All seem to be okay (did not run MemTest but Windows Memory Diagnostic, however).
4. I thought it may have been drivers, so I tried updating my video/audio drivers.
5. Ran LatencyMon to discover that tcpip.sys and ndis.sys were the culprits. Updated motherboard/on-board network card drivers, but still experienced the freezing/stuttering
6. Plugged an already-faulty iPhone charger into the front USB port. Sparked and caused smoke to come out of cable.
6. Received a "0x0000001E" BSOD on shut-down a few days after the first BSOD.

Hi All,

I've been having issues with latency after a recent build and fresh install of Win 7 Home Premium. When playing video (especially online) I see horizontal bars flash randomly on the video screen. I also hear audio crackles / cut outs when I'm playing music through Foobar and browsing the web - usually when navigating to a new page, opening a new tab, mousing over an auto-dropdown, these types of things.

I've been reading up on these issues, and have updated my Realtek drivers. I've been using a Rosewill wireless USB adapter for internet, but have noticed the same issues when connected directly to my modem as well. Only thing is, I don't see iusb3xhc.sys affecting latency any longer when I'm connected directly.

When I disable my LAN controller, I see the issue with ndis.sys disappear and it's not affecting my latency as reported by Latency Monitor.

When directly connected, I do still see ndis.sys coming up as a latency issue in Latency Monitor.

I have just uninstalled my Nvidia video drivers to see what effect it would have on the Latency Monitor finding dxgkrnl.sys being the King of latency-causing affairs on my troubled system. Now, this file is not causing issues.

So, now, being directly connected to my modem, with no video drivers installed, the issues come up as seen in my attachment. ACPI.sys and ndis.sys.

I'm at wit's end, what is my next step to get this fixed?

Thanks ahead of time for your assistance!

Hello all - hoping some real experts can shine a light on this one.

Installed a brand new mobo - Asus Sabertooth 990FX - and DPC latency checker was showing full red. Used Latency Mon to track down the culprit which was storport.sys. Searched everywhere for a driver update for storport in Win 7 and nothing exists.

Then went further and installed Windows Performance Toolkit and ran the Performance Analyzer to look at what was going on with storport. PA showed that the "RaidAdapterTimerDpcRoutine" was causing storport to spike so badly.

I'm not running any RAID drives - they're all set to AHCI in the BIOS, so I'm at a loss what to do next. All latest drivers & updates are installed. Are there RAID related drivers I can disable from device manager? Or switches in the registry?

Setup:
Windows 7 x64 SP1
Asus Sabertooth 990FX mobo
AMD Phenom II X6 1090T black edition CPU
8gig ram

A:Very high DPC latency in Windows 7 x64 caused by storport.sys

Well I seem to have finally fixed my endless DPC problems. I performed a fresh install of Windows 7 and carefully installed all drivers and updates for everything in the following order:

- Asus motherboard drivers
- Flashed the BIOS and reinstalled latest vers.
- AMD CPU drivers
- All Windows 7 important updates incl SP1
- GPU drivers
- and lastly, the drivers for the external firewire audio device.

Hardware wise, I changed the slot that the GPU was installed on. I had it in PCI slot 3, and on reading the manual, they recommended slot 1 for the GPU. I also removed an Astrotek PCI firewire adapter card which was not being used. The new mobo has an external firewire slot that I've plugged into instead.

I also kept the driver installs "lean". Only installing the essentials. So I did not install the AI utilities for the Asus mobo, as I saw the AiCharger.sys misbehaving at one point. I also only installed the graphics drivers for the GPU - not PhysX, or 3D etc etc.

Something in that mix of changes was the secret sauce to fixing the DPC problems. Now I can run video, audio, flick between screens rapidly at any resolution and DPC never peaks above about 153. I've even still got aero running. I've got fingers and toes crossed that this remains stable, but this is the first time I've ever had Win 7 so calm since first installing it 18 months ago.

Lately ive noticed that while watching youtube videos or listening to music in windows media player, ill get these random stutter moments where the computer just seems to slow down for a second. It makes my audio/ video/ and mouse all stutter.

I ran DPC Latency checker and found that at the moments I had stutters, the latency checker was spiking up to max in the red.

I read around online that it is the network card that causes this, so i disabled my network card and the latency checker remained in the green.
Then I tried reconnecting my internet via wifi while the network card was disabled, and once again I started getting spikes.
I also tried updating my network card to the latest driver and now its even worse....

can someone please help me? These random stutters are starting to get annoying.

Also a side note:
Ive noticed that if the driver is enabled, and im not doing anything network related its all fine. But once I do something like load a page or load a video, thats when I start to get the random stutters.

Since that , I just can't watch some videos anymore with the ANNOYING static/crackling sound , its very annoying .And it also seems that it affects CPU performance and fps drops.Like I said before , I installed Windows 8.1 yesterday , so no minor tweaks have been done to the system .

A:Windows 8.1 High DPC Latency,(annoying static sound)-Help.

Windows 8 Compatibility:[FONT=Arial] The DPC latency utility runs on Windows 8 but does not show correct values. The output suggests that the Windows 8 kernel performs badly and introduces a constant latency of one millisecond, which is not the case in practice. DPCs in the Windows 8 kernel behave identical to Windows 7. The utility produces incorrect results because the implementation of kernel timers has changed in Windows 8, which causes a side effect with the measuring algorithm used by the utility. Thesycon is working on a new version of the DPC latency utility and will make it available on this site as soon as it is finished.

Beside that it's most likely a hardware / driver / codec - issue.

Your system is also not really powerful as well.

Windows 8 / 8.1 are not causing that kind of issues. There is only an input-lag, which can be fixed via M$-tool, when playing older games without direct-/raw-mouse-input.

Hello!

At first everything seemed fine. Everything was working, I only needed to upgrade the VGA driver.
I have a xonar D1 card with uni-xonar which worked immediately.

Than when I listened to music I noticed clicking and stuttering which got really horrible after while.

Talked about it on hydrogenaudio: Clicking, stuttering after upgrade to Windows 10 - Hydrogenaudio Forums

I clean installed VGA, updated the LAN driver, re-installed xonar. Things improved but they still suck. Clicking is still a regular occurance.

I checked latency when LAN and the soundcard was disabled but latency still sucked:

Since I was using the very same hardware for years without these issues and I have doubts that several hardware or their drivers suddenly started misbehaving I'm guessing it might be an issue in win10 itself.

I attached the latest measurements. (screenshots and report) The worst values still belong to the same as the first time: VGA, soundcard, LAN, USB, ntoskernel

Don't know what else to do.

A:Clicking, stuttering sound after upgrade to Windows 10 - High latency

The latency-problem is usually caused by the latest Intel network driver. There are countless threads about this and easily google-able. There is no real help, Intel is promising to "look into it" for over a year now and still no fix.
I changed to Realtek NIC because of that - best €10 I ever bought for the computer, to have no problems.

Hi guys,
Yesterday evening I was watching some youtube videos when suddenly the sound cut out. I turned the volume back up only to find there was a loud staticky crackling pop as the only audio output. Audio output is fine on headphones.

I have a Lenovo Yoga 920 (with highest specs) with Windows 10 home 64x bit. Since the issue arose, I have tried several things:
- disable/enable drivers by REALTEK related to sound, and Qualcomm Wifi Network Adapter

-Reinstall drivers via windows and directly via REALTEK website
- Update Windows 10 OS as well as BIOS
- Messed around with several battery plan settings
- Restored PC to previous backup, then messed around with audio mixer. This helped, as there was no distortion until volume 20, but beyond that it was the exact same issue.
- Lastly, I resorted to just resetting my computer (deleting all files, etc.)
My next step would be to do a clean install of windows 10 but I need to be using my computer and was wondering if there is a better way.

I believe this is a software/driver related issue as I was partially able to fix it by messing with the mixer settings (even when not having restored my PC). However, this "fix" doesn't work since I reset my PC...

I would kindly take any suggestions since I am so desperate that I am considering trowing this device out the window.

Here are my specs:

OS Name Microsoft Windows 7 Home Premium
Version 6.1.7600 Build 7600
System Manufacturer Dell Inc.
System Model Studio 1558
Processor Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz, 2400 Mhz, 2 Core(s), 4 Logical Processor(s)
Installed Physical Memory (RAM) 4.00 GB
Name ATI Mobility Radeon HD 5400 Series
Adapter Description ATI Mobility Radeon HD 5400 Series
Adapter RAM 1.00 GB (1,073,741,824 bytes)

A:High CPU usage, low fps, high latency.

All of your symptoms could be a driver issue. Please download this free latency checker and run it to see if it is.

Hello, everyone!

First of all, here are my PC specs:
OS: Windows 10 Pro x64 (Latest updates)CPU: AMD A10 5800k @ 4.4 GHzMotherboard: MSi FM2 A75MA-E35GPU: MSi R9 380 Gaming 4gRAM: 2x4GB Kingston HyperX Fury Black 1866MHzPSU: Silverstone Strider ST60F 600W 80+Bronze FMStorage: Samsung SSD 850 Evo 250GB (Windows), WD Blue 1TB WD10EZEX (Games), WD Blue 250GB WD2500BEVT (Music and Media), 500GB Toshiba drive in external Rosewill case (Backups)

A few months ago I started noticing that my audio would "pop" from time to time when watching videos or playing games. Some time after that, it got worse, to the point where the PC freezes for a few moments before "catching up". After a lot of searching, I finally learned that it was all due to high DPC issues. Its been two weeks since I've been trying to get rid of it with no success. Thanks to the program called LatencyMon I managed to log what exactly causes the high DPC. The culprits are HDAudBus.sys, ndis.sys, and USBPORT.SYS.

I read almost everywhere that had a DPC thread, that the network driver (ndis.sys) would cause trouble when using a torrent program. However, this didn't help me at all since I almost never use qBittorent, which is the one I have installed. In terms of audio, an outdated Realtek driver would cause issues, except I'm using all the latest drivers for my motherboard. Regarding the usb related one, I read that unplugging all other usb devices other than keyboard and mouse would get rid of it. ... Read more

Hi, hope you guys can help me out.

My issue is that whenever i log onto WoW, my latency is 2.5k or above and as soon as i enter anything, even just jumping around in the cities, i get Dc'ed.

First i thought it was a virus, so i cleaned out my computer and reinstalled everything. I haven't installed any ui mods or addons, fearing that it might have been those that caused the problems.

I'm playing on a laptop, which has a tendency to get pretty hot some times, but i've been playing on it every since i got it in November 06 and haven't really had problems before now.

It's a 2 ghz core2duo, with 1 gb rams and a geforce go7600. I'm playing with a 20 mbit connection, and not on wireless.

What do i need to do? is it my router that is messing things up via a firewall or a port i need to open?

any help is greatly appreciated

Well lets start here by asking what type of network card you have and router? Are both up to date with the latest drivers and firmware for the router? Does the router support IPv6? if no on the IPv6 disable it and see if that fixes the issue.

Ok, I have been playin Asheron's Call 2 for about a week now, i had to purchase a new video card in order to play it. I'm only 15 so I got the cheapest one I could find, which was the Radeon 7500. While i'm playing, my latency seems to sky-rocket from my usual no lag rating of 146 to an intensely high lag rating of 200-2000! In my computer, im running 2.0Ghz, 256Mb DDR ram, 40Gb hard drive. The Radeon 7500 has 64Mb of ram and so on if you didnt already know. I've asked many people what to do in order to end my lagging spree which if I may add makes the game very un-enjoyable, some have said to get a better video card, and others have said to get more ram. I just wanted to comfirm with you guys which is need.

I ran DPC Latency Checker with drivers disabled for Network adapters, Internal modems, Internal sound devices, Comm 1, Printer, Portable Devices G:, H:, I:, and J:, Imaging devices, DVD/CD-ROM Devices, UPS, and Acronic Backup Archive Explorer. The result was latency exceeding 1600 Microseconds for at least one second out of every minute.

I looked at RATTV3, but the documentation said it was for Windows XP and I am using a Windows 7 Home Premium 32 bit OS.

ParetoLogic Health Advisor says one of my drivers is not up to date, but it is a Microsoft driver and Microsoft says it is the latest version. ParetoLogic anti-virus did a thorough check (12 hours) and found no viruses. Zone Alarm finds no viruses.

The system is very slow much of the time and the speakers crackle from time to time. I was having blue screens several times a day, but afterscanning with the Health Advisor they only occur about once a day.

Any ideas about how I can fix this?

I've had broadband for a few months from central-point, 512mg. I used to get speeds of about 70kbs download and latencies of about 40-60 on Counter-Strike Source. Now, I get downloads of about 50-60kbs (not too bothered about that) but latencies of about 300-500 on CS:S! Anybody have any ideas? I did have some problems with my router, and I restarted it, but I'm not sure if that was before or after the low latency.

I've emailed central-point, but I fear it's a scam to get me to buy 1mg.

Hi!

I have problem with latency! I have Sony Vaio VPCF12M1E/H laptop with Samsung SSD.
Current OS is Windows 7 x64.

In last two days i have reinstalled OS three times! And still no success.
I have tried running LatencyMon with default OS (microsoft) drivers and with latest drivers from manufacturer.

I have tried to disable many devices in device manager step by step but the problem is still here.

So i guess its not software... Am i right?
It is very annoying! And i cant use this laptop like that! If i watch youtube i hear "clicks & pops" every few seconds. Annoying!

Is there any way to solve this problem?

A:High DPC latency

Can't seem to edit the thread above, so ill explain here about what happened.

2 days ago I was getting weird popping/cracking sounds coming from my audio, so I googles it and dled dpc latency checker. It was in all green around 300-400us and every once in a while I would get a spike to over 100kus for about 1 second and you can hear the crackling sound in the audio.

Well I restarted my pc and I checked the dpc latency checker and I was getting more yellows and reds than before, so I thought I had a virus or something. So I started disabling/enabling drivers and it didn't fix my problem.

Downloaded nod32 and ran a scan and it didn't find anything. Restarted my comp and now dpc latency checker shows nothing but red in the 10k+ us range. My computer is to sluggish to do anything now.

So I tried combofix and I got BSOD, thought I had a virus yet again. Booted into safe mode and ran combofix and I posted its deletion log in the other thread.

Well as of today im still in the red and have no idea what is going on...

Seems like a problem with your internet provider. Ring them up (or email if you prefer) and ask them if they can turn off interleaving as you are having ping/latency issues. That's what my ISP did and my ping on counter strike went from 100ms+ to 10-20ms.

There may be an option in your router to turn it off but contacting your ISP is the best bet.

Hey folks

I've run into a strange something, which I can't find any explanation for.

Whenever I turn on WLAN in my router, the whole network suffers from an incredible latency. No online game is playable, but the download speed itself is not being touched (i.e. fullspeed) and websites load - even if they're a bit slower, it seems.
Once I'm switching WLAN off, it is all back to normal again.

I have really no clue about the source of this evil and due to the nature, it's actually hard to google, as you'd only find problems of people that have high latency over the WLAN devices. I'm experiencing all this stuff on my normal LAN PCs as well, though.

So.. if anybody could point me in the right direction, I'd be overly grateful.

Thanks in advance.

Cheers

Jan

WLAN should only be on when you are trying to pair your router with another wireless device at that moment.

Once paired it does not need to be on.

Recently I had some High DPC Latency which I believe was the cause of some sound stuttering. I believed it was my headset but when my new headset, Sennheiser PC363D, came in I had the same problem. At the time I was unaware of what DPC Latency was and just thought my old headset was dying. When I used my new headset I experienced the same stutter in sound. I never once experienced any stutter in sound when I use my TV, I use a TV as a monitor.

I ended up switching USB ports a couple times and found that I no longer had any sound stutter but I was still experiencing High DPC Latency.

If I am playing music through youtube and teamspeak I experience on average 550 DPC Latency.

If I turn on OBS to stream I experience around 600-700 DPC Latency

If I turn on Steam to play games I experience about 12000+ DPC Latency

Now I know none of this is normal because my friends are running all of this on computers that are not as strong as mine and are averaging 50 DPC Latency, 130 DPC Latency, and 80 DPC Latency.

I tried doing this guide How to Diagnose and Fix High DPC Latency Issues with WPA (Windows Vista/7/8) - Sysnative Forums but I was getting stuck on this part xperf -d %userprofile%\Desktop\trace.etl

I was wondering if anyone would be able to help me lower my DPC Latency or give me an explanation why mine is so much higher than my friends who rigs are not as good as mine.

Either way thanks for the help ahead of time! As a note I am not extremely tech savvy bu... Read more

A:High DPC Latency No Stuttering

I am assuming you are using Windows 7 Ultimate.

1. Forget about "xperf -d %userprofile%\Desktop\trace.etl". That is part of a toolkit for Windows 8. The only reason they suggest using it, is that LatencyMon is not compatible with Windows 8.

2. Download and install LatencyMon from Resplendence Software - Advanced System Tools and Developer Components

3. Download DPC Latency Checker from DPC Latency Checker

4. Run DPC Latency Checker. Note if you are still having high latency.

5. If you area experiencing high latency, run LatencyMon. From there look at the Processes tab and Drivers tab and see which processes and drivers are causing the most amount of latency. If it is a process causing the issue, try ending the process to see if things improve. If it is a driver, try updating the driver.

6. If you need to disable prevent a driver or process from running at startup, download and install Autoruns from Autoruns Download Be sure to run as administrator and be sure you know what you are disabling before you do so. To disable something from startup, just uncheck the box next to the item (do not delete it!).

7. If you suspect a virus or malware, post your problem in Windows 7 Forum - BleepingComputer.com Bleeping Computer is very reliable and would be a great place to help you with such things.

Notes: If it is specifically the USB driver, also try unplugging everything from your USB ports to see if that helps. USB 2 generally has a higher contribution to D... Read more
