Having an issue with latency/audio dropouts stutter on my new pc not sure what is causing it

[Mattyblueeyes]

So ive just built a new PC and i was checking latency through latency mon when i have having these spikes when just running it idle after booting my PC. Ive got a i9 13900k and a 4090 z970-f gaming wifi MB what would be causing this kind of spikes as im not that familiar with latency mon and i cant work it out.

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 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 0:05:01 (h:mm:ss) on all processors.

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 (µs): 14529.80
Average measured interrupt to process latency (µs): 5.359342

Highest measured interrupt to DPC latency (µs): 633.0
Average measured interrupt to DPC latency (µs): 1.045420


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

_________________________________________________________________________________________________________
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.

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.

Process with highest pagefault count: hwinfo64.exe

Total number of hard pagefaults 2752
Hard pagefault count of hardest hit process: 1328
Number of processes hit: 27

I understand the nvidia drivers are known to cause latency im more referring to the huge spike in highest measured interrupt to process latency. This is also with high power plan and max performance on graphics card. Any help is appreciated

 

[Bill_Bright]

And did you do as advised? Is your BIOS current? Is the OS current? Drivers?

How much RAM is installed?

As far as I know, NVIDIA (as an entire brand) is not susceptible to latency issues any more than AMD. My NVIDIA, for example, is showing all green in LatencyMon.

Well this is whats odd i just played COD MW2 and it was all green it only seems to happen when starting my pc that i get these huge latency spikes ive tested it a few times now in games or like 10 mins after starting and its all green and normal. Bios is updated 32gb ram windows 11 and drivers are all current/up to date unless there is some that im missing they arer up to date off my mb website which is a z790-f gaming wifi i9 13900k 4090. If you google about latency and nvidia drivers there are tons of people having latency issues with nvidia drivers so much so nvidia even noted it as an issue in one of the last drivers that came out. https://www.nvidia.com/en-us/geforc...orce-grd-52849-feedback-thread-released-2823/ - under open issues

 

[Bill_Bright]

I know there are issues NVIDIA. I am just saying if you google AMD drivers and latency, you will find many hits there too.

Frankly, I do not put a lot of stock in LatencyMon results - unless I can actually hear or see latency issues.

Have you tried any other programs, like DPC Latency Checker?

Disclaimer: While I have some experience with latency issues, I am NOT claiming any expertise in this area. All I can promise is that I will try not to lead you astray.

I am far from an expert in this area also I just appreciate you actually responding and trying to help I didn't mean to come across as rude i just misunderstood what you wrote, I have not tried any other programs yeah I mean it could just be a case of something loading upon boot that is randomly causing the spike cause it seems after about 5 mins of the pc being booted up everything is fine which seems odd I have seen a post about people with 12th and 13th gen on windows 11 having this issue that I was just reading. Does seem similar to the latency spikes i am getting https://www.reddit.com/r/intel/comments/10u5amb but who knows. There is definitely not an issue when I'm playing games from what I can tell I just played MW2 and it ran completely smooth for quite some time latency mon was all green and low, the only game ive noticed spikes on latency mon and maybe some audio issues is rdr2 when playing the story so idk if that is just an issue to do with that game specifically.

Ive just used the bitsum highest performance power plan which comes with process lasso and the issue is completely gone im not getting any spikes at all on boot virtually. It disables core parking completely so im wondering if this is an issue with core parking in windows 11 or just with 12th and 13th gen cpus in general but yeah the issue seem to be completely gone i just ran it on boot and got 0 spikes above 150 and whats even more interesting is the nvidia driver doesn't seem to be spiking as high anymore either.

 

[erocker]

Last Nvidia driver's notes mentions this issue. Try rolling back to a previous driver. That being said it could just be different sound devices causing it. Go into your device manager and disable all sound devices you aren't using.

 

[Bill_Bright]

I didn't mean to come across as rude

Rest assured, I never felt that. We're good.

 

[ThrashZone]

Hi,
I have looked up latency mon but when was the last update for the utility ?

New system might not be all that compatible with it seeing even ddr5 doubles latency for 50% more frequency.

I have no idea tbh you could for sure be on to something but like i said for the most part when i run bitsum highest performance the spikes in latency mon go still getting them in rdr2 but seems like the only game its happening and the game runs smooth so idk why it is like that.

 

[ThrashZone]

Hi,
You should fill in your system spec's page and switch it to yes show system spec's

https://www.techpowerup.com/forums/account/specs

But example ddr4 quad channel on x299 runs around mid 40's at 4000ghz
And ddr5 say 6000ghz is hitting around low to mid 60 and is shown as quad because it's dual channel per stick.
But if your thinking 4090 is high latency wise IDK where to check that besides what you're already doing = game play.

AIDA64 can show latency as well which has a 30 day freebie period
Also check out some of the lastest post for simalar hardware as your own you might feel more at ease and or see some ddr5 timing tips

Share your AIDA 64 cache and memory benchmark here

Hey folks, how about sharing some cache and memory benchmark you get using AIDA 64? Rules: Use the latest stable(non alpha/beta) version of AIDA(currently 4.50.3000) So here goes mine. All the best. :) Table as requested. In order of entry.... Only the best scores of an individual are...

Just because an app has not been updated recently does not mean it cannot effectively do what it was designed to do. Latencies are all about time. And last I heard, 1 second still equals exactly 1000.0 milliseconds. So as long as the operating system supports running that app, and as long as there are no unresolved bugs that might affect the accurate counting of milliseconds, no big deal.

Installing nvidia drivers in MSI mode can help with DPC latency. Try it out with TPUs nvcleaninstall if you haven't yet.
