It just keeps it from down clocking and up clocking all the time. I keep the p2 state off all the time and it stays at 39c without doing gaming. I also use MSI to change fan speed. It also keeps my 4k movies running smoothly.
Each to there own however, will see if I can find another solution for you. There might be one more I can get you to try at the moment.
The first time of uninstalling, reinstalling drivers my rtx clock was unchanged, like starting pc and 1755Mhz in idle with 170W on the wall.
Then i use DDU, installing 527.56 drivers and now looks like the clock is the default in idle.
Right now opening afterburner looks fine, as was at default.
its reverted to the original status, right? you scared me out with this P2 state
EDIT: i was wrong, 170W at wall is (obviously) for "Prefer Maximum Performance" in Global Profile of Nvidia CP
Not related with P2 state
Sorry, I am a bit afraid, because I don't know where to post without being moderated.
I don't really know if it's Dell , Nvidia 3070 (from Dell) , a faulty motherboard (dell), a bad driver, or Windows 11 Pro but while current measured interrupt is fluctuating between 40-150 μs (which not optimal of course), I get some spikes around 700+μς (it happens once in 2-3 minutes) and and some super extreme spikes around 38.000μs which might happen once in 10, 20, 30 or minutes (with ntoskrnl exe and wdf01000.sys to be responible)
I tried EVERYTHING (from Dpc latency guide).
My actual question is, what are the chances that a motherboard replacement and a clean install of windows will help?
(That's what dell's technicians suggested, but I doubt they know anything about DPC latency, because when I told them about sound crackles and pops the first answer was that my speakers are incompatible with Dell!!!)

This is a lot of questions to answer, and yes it is a post that we're asking people to not do anymore because they've all been answered many times over, but it seems that we need to continue to clarify this stuff, because people are still confused by this thread:
1) You have an Nvidia 3070, so yes your issues are probably coming from that graphics card. You did not post any LatencyMon screenshots so we cannot know for sure.
2) ntoskrnl and wdf01000 spiking into the thousands is partially from the Nvidia driver because that issue compounds all other problems, but spikes this high need to be addressed before installing the Nvidia driver as they are their own problems. I can only say that the DPC Latency guide and my other guides will fix these, until someone shows me that it doesn't, with good proof.
3) You said you tried everything from the DPC Latency guide, but it has only been posted for a few hours. Did you actually do the steps that deal with reinstalling Windows, because I find it really hard to believe that you installed firmware for every device, bios updates, reconfigured bios settings, troubleshooted your non-Nvidia driver problems, and created/installed a clean Windows using an optimized image in this time, and also saw no results for any of this.
4) Replacing hardware is almost never needed, unless something actually dies or is dying, and when that happens you usually know it. For example, a graphics card that is dying will start to display artifacts on the screen. A power supply that is failing or dead will not boot up when you press the power button. Usually, tech support telling you to replace a part is just their version of "I'm out of options".

Thank you for your reply!
DPC latency is an issue i found last week on my new DEll XPS pc, so many of your suggestions have been already tested, except for new Windows install, but we are talking about a brand new PC.
I just received the new motherboard from Dell, it is refurbished that makes me even more anxious about what new is going to come up....
I Did provide some pictures in a previous post, but it was moderated.
As for nvidia, I totally removed drivers with safe mode+DDU, and my tested the pc without a nvidia drivers and the spikes were still there.
(Also tried to diable Realtek, wifi, and every device that is not vital for a PC to run)
I can tell for sure that my old pc (Ryzen 2600+rx580+16gb ddr4) is much more snappy than the new one (I7 12700K , 3070, 32ran ddr5).
Latencymon on my old pc fluctuates between 8μs - 40μs, with only one spike up to 400μs) and I didn't even tried any tweak (because I never felt the need to do so).
To chime back in: I've tried installing the latest Nvidia drivers which resulted in crazy latency spikes again. So I'm back to the known working versions.
Hello!
I would like to thank very much for anyone that has contributed to this thread and so on. Last week when I installed a M2, I started having the dreadful nvdlmkm crash everytime i'd play a game. It would happen in 10 minutes, 30 minutes, 60 minutes... For reference my PC is new, I built it in December and the only new thing is the M2 ssd from last week.
Tried almost everything I could find on google. Reseat ram, try different pcie slot on gpu, switch display ports, DDU... i'm sure we all know at this point what it says lol, the only things I didn't do were change my hardware as I don't have any other avaliable to test.
Luckily I came across this thread and tried a few things written here + Hellbovine's DPC Latency thread (not all the things written there, mind you.)
Specifically I have: installed nvidia driver without the bloat using NVinstaller, driver version 511.65, enabled XMP on my Ram, made pcie lane 8x4x4 & pcie gen 4 (not sure if this even helped but oh well) and finally changed cpu to be on eco-mode (45w). I have also uninstalled all my audio drivers with DDU.
Maybe i'm celebrating too early as it's only been 30 minutes i've done these things, but before my Highest Reported DPC would be nvldmkm or wdf01000.sys with extremely high values, now it's not that bad. I usually would get random sutters? too, but so far they don't show up. I'm sure there are more things I can do to improve the latency but as long as my games don't crash i'm happy
I think messing with the BIOS was probably your solution. It looks to me like there has been a trend in this thread where NVME/M.2 may be the main contributor to wdf01000.sys problems, and now it's starting to make sense why.
NVME/M.2 Drives
I'm seeing a lot of people with serious DPC issues into the thousands, and more often than not they are running an NVME/m.2 drive. In addition to that, a few people have mentioned that they dropped from the thousands into the hundreds by changing the BIOS settings that control these drives. It's becoming pretty clear to me that these drives are finicky, and need an optimally configured BIOS to prevent problems.
I have a traditional Sata SSD so I can't really test these things, which is why I've been hesitant about discussing it because I don't want to accidentally spread misinformation. What I would suggest for everyone with these drives is to check out the BIOS options you have for them, and then discuss amongst yourselves on this thread what the optimal settings are, then I can add that information to my DPC Latency guide once a consensus has been reached.
Here's two support articles (link1, link2) on the topic I came across a few days ago.
POWER / BIOS SETTINGS
Some other tweaks I've seen appearing often in similar support articles, is making sure USB Selective Suspend is disabled in the active power plan, as well as disabling PCIe ASPM (both are included already in my optimized image guide).
The BIOS is really the proper place to start first with DPC issues, as most of the heavy lifting is done there. The important thing to realize about the BIOS is that it controls what the operating system can and cannot do. If something gets disabled in the BIOS, then Windows is not allowed under any circumstance to use that feature, and then you don't have to worry about tracking down the multiple places in the operating system where you would need to toggle settings to disable it there. The other beneficial thing about the BIOS is that it doesn't care which operating system you are using, nor does it care about version or edition of that operating system, as the BIOS settings are global and override everything.
The best thing everyone in this thread can do for easy performance and DPC improvements, is write down every single BIOS option they have, and Google them to learn, then toggle off all the ones related to power savings (of which there are tons). If you find any settings that made a major impact and they aren't in the DPC guide already, let me know so I can add them. Right now all I can do reliably is add settings I have in my computers since I can test those. I know I'm missing some important ones, especially the ones from newer motherboards, simply because my BIOS doesn't allow me to toggle them. Something I had to learn the hard way over the years is to research motherboards thoroughly before building a new PC, because you can get stuck with one that has a crappy BIOS with limited settings if you don't.
So I've managed to completely mess up my system to the point that it won't even load into Windows 10. Even safe mode results in an instant BSOD.
How it got to this:
After updating drivers and applying small tweaks (Interrupt Affinity Policy, MSI mode, etc.) I got some decent DPC results (see previous post) so i decided to do a complete check on all drivers and firmwares to see if it was possible to further improve things. I've updated the Nvidia Driver to version 528.02 and updated the MSI BIOS to the latest version. But then.. It got a lot worse! I noticed the clicking and ticking audio again and I couldn't figure out why. I checked Latencymon and the spikes now went up in the 1000's to 2000's.
So I thought there must be something else. I've found the chipset driver to be outdated. On the MSI Manufacturer website they don't offer a driver download, so I went to the AMD website and got it there. It wouldn't let me install the Chipset driver because of some corrupted registry keys (installation failed every time I tried), so I found a Tool from the Microsoft website which helped me fix that. Next I've installed the M.2 SSD driver from Samsung website (already had the standard driver from Windows installed, but who knows this improves latency). I did another clean Nvidia driver installation back to the previous version. But it didn't help as well. I tried removing the Interrupt Affinity Policy's and Interrupt priority settings. But no.
The only thing I couldn't revert was the BIOS version. Since MSI removed the previous version from their download page regarding a bug that occurs in some systems.
Nothing worked. I couldn't get my system back to the acceptable range (occasional spikes to 280), So I decided to use the System Restore Point that I made before making all these changes and tweaks. Little did I know that System Restore can in fact completely trash the system. I am now left with a system that won't boot at all! I tried disabling 'driver signature enforcement' at the recovery screen and tried entering safe mode but it gives me an instant BSOD, Now I am afraid I might lose all my files and music projects.
I still have a recovery USB from Macrium reflect (cloning software) from when I upgraded my SATA SSD to the new M.2 NVMe SSD (This is when I started noticing the Latency issues, which brought me to this forum, So Hellbovine maybe you're on to something being it M.2 or BIOS related for some users).
TLDR:
- Tried to make more DPC latency improvements
- Updated various drivers (GPU, Chipset, SSD) and BIOS firmware
- DPC readings went worse (up to 2000 and higher)
- Tried to revert all tweaks and settings, didn't work.
- Tried to revert to a System Restore point to before I did all the system tweaks and driver updates.
- This completely wrecked Windows 10 to the point that it doesn't boot anymore, even in Safe mode.
- Tried to disable 'driver signature enforcement' didn't work
- Now I am left wondering if I can recover my files and music projects

EDIT:
Sorry for the long post. @Mods Should I start a new topic on this? It's kinda related to the Nvidia driver bug, but I am not sure anymore.
Please read the previous (recent) posts. This point, the thread is only looking for success stories to find answers.
If you got broken NVIDIA issues, join the crowd. We're not attempting to fix those issues. But NVMe might be a common factor in the DPC question, so your tale of woe might still be a helpful clue.
Just as a reminder, Hellbovine is working thru reported cases by himself. But NTLite forum isn't a specialist site for NVIDIA problems.
Everyone's welcome to track this thread, but he's mostly trying to see which advice works better than others.
I'm going to write 2 responses to address this, one for your specific situation so that I can teach other people, and another generalized post for non-Nvidia DPC issues. Below I try to touch on all the points in your post, and explain why things went wrong.
Interrupt Affinity Policy
I never condoned this, in fact I keep saying I don't think it's a good solution. Check my previous posts for info on that. It's volatile and will break systems, it's not a tweak for anyone except the most advanced computer users that really understand what's going on. I'm sure this is a huge part of why the tool was discontinued many years ago by Microsoft, long before W10 was even released. It's not meant for W10/W11, and there's a lot more to it, which is why I keep trying to avoid it. Notice how this tweak was NOT in my DPC Latency guide?
MSI Mode
I never condoned this, and like the interrupt tool it's misunderstood and complicated which is why I keep avoiding it. It's my understanding that some/many of the modern Nvidia cards already use MSI mode anyway, so those people aren't "enabling" it, it's already enabled. Also, according to some of the veterans at guru3d MSI mode has nothing to do with DPC (their words). Here's my logic: Nvidia and AMD are competing, they both appear in tons of gaming news and benchmarking articles. If MSI mode was a flat improvement it would always be used by default. These companies aren't completely stupid, the reason it's not enabled is because of compatibility issues or other reasons. If we were talking about Microsoft this logic doesn't apply, because they have zero competition, it's a monopoly, so they do whatever the hell they want, which is often suboptimal. Notice how this tweak was NOT in my DPC Latency guide?
BIOS Update
There were very specific protocols I listed for this, of which none of them were mentioned in your post. Did you reset it to defaults? Did you then optimize settings? This step is in my DPC Latency guide.
Chipset Driver
You said "It wouldn't let me install the Chipset driver because of some corrupted registry keys". I'm a broken record here, the solution here is a clean/proper install of Windows. This was skipped in your posts and why you have so many issues, as well as other people. Nobody is listening to me, install Windows cleanly and properly following all the steps I laid out. You MUST either integrate registry keys to pause Windows update by default AND also keys to stop automatic driver installation, OR unplug from the internet BEFORE installing Windows. Seriously, probably 75% of all Windows problems can be resolved by this one step. This step is in my DPC Latency guide and keeps being ignored by just about everyone.
Nvidia Driver
DPC issues for Nvidia are NOT going to be resolved by changing drivers. The problem has existed for YEARS, all of the drivers since at least Windows 7 have this issue. This thread confirms this to me, and not a single person has yet to show that a certain driver actually resolved issues, there's always something major wrong with their posts, such as no screenshots of before/after, or other red flags. It's a waste of time to try and troubleshoot this with DDU/NvCleanStall, it has nothing to do with the problem, it's ruled out entirely. Notice how this was NOT in my DPC Latency guide?
System Restore
I think System Restore is useless and causes more problems than it fixes, and should never be used. A clean install is *always* the way to go to fix issues that make someone want to use a restore point. Keep in mind I'm talking about gamers and home users, I'm not talking about IT/Corporations or anyone else that might benefit from these kinds of things. Notice how system restore doesn't appear in ANY of my guides?
Cloning Software
Again, I don't condone this, just like System Restore. A clean install is *always* the way to go. Notice how this software doesn't appear in ANY of my guides?
Driver Signature Enforcement
I don't know a lot about this, I read a few things on it and it didn't interest me at this time because I don't think it's relevant to probably 99% of all users. Everyone should only be installing the latest, official drivers straight from the manufacturer of each piece of hardware.
Data Recovery
How do you recover your info, now that Windows is borked? I wrote a guide (link) on that too, who would have thought!
I'm really not being mean here, I promise, but you and many others are in this DPC nightmare because you aren't following directions. On top of that, you guys are doing a lot of stuff that's not recommended too. It's really this simple: follow the guides exactly as written, to the letter, THEN let me know if you still have issues, and I'll help you. Until then, I refuse to troubleshoot issues that are self-inflicted anymore in this thread, it's exhausting and not productive, because I'm not sure I'm even teaching anyone anything at this point, since so much of what I say is ignored.
To everyone struggling with DPC issues that are not related to Nvidia, this post is for you.
Your problems can be solved, and we can make your computer run better than it ever has, but you must follow the guides to the letter, don't skim through or skip steps. Even if you disagree with something, do it anyway to gain the hands-on knowledge because there will be "eureka" moments and you will learn a lot in the process. If you run into problems and something needs to be fixed in any of the guides, please let me know so I can improve them, but I need people to follow directions before complaining.
This will be the final non-Nvidia post from me in this thread, all other posts discussing non-Nvidia problems will be linked back to this post with no further explanation because we've given out many announcements so far and they are being ignored. It's time to get productive again and stop wasting time on people's self-inflicted issues. Do not participate in this thread unless you have zero DPC issues, except for the Nvidia driver.
Below is everything you need to fix your non-Nvidia DPC issues and improve your machine's overall gaming performance. Reserve one week where you will sit down and focus hard on these guides. Follow them precisely as written, and do them all. You will be reinstalling Windows several times during the process, but you will learn years of knowledge in this short period of time, and can then become self-sufficient in how to solve problems and optimize things on your own, plus you'll have a better gaming computer after all that hard work.
NON-NVIDIA DPC ISSUES
To everyone struggling with DPC issues that are NOT related to Nvidia, this post is for you.
Your problems can be solved, and we can make your computer run better than it ever has, but you MUST follow the guides to the letter, don't skim through or skip steps. Even if you disagree with something, do it anyway, just to gain the hands-on knowledge, because there will be "eureka" moments and you will learn a lot in the process. If you run into problems and something needs to be fixed in any of the guides, please let me know so I can improve them, but I need people to follow directions BEFORE complaining. Not following directions is by far the #1 problem when it comes to DPC/performance issues.
This will be the FINAL non-Nvidia post from me in this thread, all other posts discussing non-Nvidia problems will be linked back to this post with no further explanation, because we've given out many announcements so far and they are being ignored. It's time to get productive again and stop wasting time on people's self-inflicted issues, this thread has derailed long enough. Do NOT participate in this thread unless you have no DPC issues, except for the Nvidia driver. This thread is ONLY about finding a solution for the NVIDIA driver, nothing else. If you actually followed the entire DPC Latency guide and still have problems, then please post over in that thread with a detailed summary of your non-Nvidia issues and I will assist.
Below is *everything* you need to fix your non-Nvidia DPC issues and improve your machine's overall gaming performance. Reserve one week where you will sit down and focus hard on your computer and these guides. Follow them precisely as written, and do all of them. You will be reinstalling Windows several times during the process, but you will learn YEARS of knowledge in a short time span, and can then become self-sufficient in how to solve problems and optimize things in the future on your own, plus you'll have an optimized gaming rig after all that hard work.
Do these guides in order, and don't skip any steps, even if some of the guides overlap with others, because every guide is written as a standalone and so the steps that come later, rely on the previous steps in that guide. The whole point is to learn how/why problems exist, and what to do to avoid them. You will be learning how to do things properly, so that in the end you have a gaming machine that you enjoy playing on.
I cannot stress enough that the ordering of things in a computer is important. The reason we do things like telling people to fully optimize their bios BEFORE installing Windows, is because it matters. Windows is dynamic, it adjusts things during install based on your hardware/BIOS. It is not efficient or proper to work on a computer that is fully installed with all sorts of apps, games, active internet connection, Windows update and Defender running, and all the bloatware tools like MSI afterburner, Nvidia GeforceExperience, etcetera. You have to optimize from ground zero, on a clean system, not the other way around.
Guide #1: NTLite For Beginners https://www.ntlite.com/community/index.php?threads/guide-ntlite-for-beginners.2979/
Note: version 22H2 is out now, so the Microsoft ISO link will point to that unfortunately. Because 22H2 is bugged and should not be used, you will have to use another website, like uudump.net or the Rufus script to download the 21H2 ISO. I will not troubleshoot 22H2 since it has major bugs (link).
Guide #3: Optimized Image https://www.ntlite.com/community/index.php?threads/guide-optimized-image.2990/
Note: all of the small guides I have written, such as "Optimizing Cortana", "Pausing Windows Updates", and "Start Menu and Taskbar" are all already included as a part of this optimized image guide, which is why they aren't listed in this post. Those smaller guides were just for people that already have optimized systems and needed that information to further enhance their images if desired.
NOTE: This thread was deleted and re-posted with the help of a moderator, to clear the derailment that was taking place. Keep all replies related to the contents of this guide, and do not post about the Nvidia bug in this thread. Disagreeing with parts of the guide is okay, but it needs to be...
If I can add something as well. Start with one part,restart, then test. If better backup and start number 2 and so forth. This way if one thing buggers you up you won't have too go through it all again to figure it out which caused the problem.
Please read the previous (recent) posts. At this point, the thread is only looking for success stories to find answers. Please read through the the following
Does your computer have frame rate stuttering, audio drop-outs, or other noticeable problems while playing a game or working on audio production? If so, it may be due to high DPC latency, which is an extremely important topic that often gets overlooked in gaming websites, forums, and benchmarks...
Ok the thread is closed, but i want to share a workaround to fix DPC issues caused by Nvidia idle power management.
The problem, as you all maybe know is the costant on/off of the GPU caused by the driver and power management setting.
In fact if you set "Prefer maximum performance" in your Nvidia Control Panel, the DPC magically get fixed (if the problem was only from Nvidia drivers)
That setting have a negative side, because is a lot more power used for idle status.
The goal is to set a low idle power fixed, and i have achieve this with a profile in Afterburner.
Quick review of my fresh Windows 11 Pro 22H2 installation / DPC status
Real photo for less interference, also you can look at the power consumption from last screen where power of GPU is fixed to 1065Mhz at 762mV with 92W on the wall
Its a workaround of course, but usable as a profile.
Nvidia never fix it, its a feature for less power consumption. The wrong side is, the choices: OR LIKE THIS OR MAXIMUM POWER EVERYTIME
Hope this help someone
In fact if you set "Prefer maximum performance" in your Nvidia Control Panel, the DPC magically get fixed (if the problem was only from Nvidia drivers)
Already mentioned here, and from my own experience it does not work.
Locked, because you failed to read Hellbovine's request about reading the full thread before posting
Nvidia Display Driver:
If you are coming here because of DPC issues with your Nvidia driver, we have a separate thread dedicated to that (link). Please don't post in that thread until you've read through all the links on the first post of page 1. Right now there is no known, universal solution, for fixing that driver.
This bug has finally been recognized by Nvidia, and is now on their open issues tracker. It sounds like this NTLite thread was a driving force in getting it recognized, so thank you everyone that was involved, I really appreciate the time and effort from the participants.
1) The open issues (link) states: Increase in DPC latency observed in Latencymon [3952556].
2) The top comment on a Reddit thread (link) states: Wow the increased DPC latency actually listed as a known issue!
3) A moderator at the Nvidia developer forum (link) states: ...I have forwarded this information as an internal ticket to QA/Engineering...
At this point we just need to wait for Nvidia to fix it, and if a few months go by and they don't, then we need everyone with the bug to keep submitting support tickets to Nvidia, as well as using the Feedback Hub app to submit a ticket to Microsoft, until it gets fixed, since it's clearly not an issue caused by consumers, or one that we can mitigate on our side, it requires updates to solve it.
