Hello,
I have been dealing with this issue for the longest time. In most games, I drop FPS or the game micro stutters randomly, and it ruins the immersion for me, I really hate it. What can I do to fix this?

Here are my specs:
  • CPU: Intel i7 7700k @ 4.2GHz
  • GPU: ASUS GeForce GTX1080Ti ROG Poseidon Platinum (I have to note that I don't run water cooling through my GPU, even though it is a Poseidon.)
  • RAM: GSKILL 16GB Trident Z DDR4 3000MHz RGB
  • PSU: Thermaltake Smartpower 80PLUS Bronze 650W
  • Motherboard: ASUS ROG Maximus IX Hero
  • Drive 1 (Harddisk): WD 1TB Caviar Blue 7200Rpm
  • Drive 2 (SSD): Corsair 480GB Force PCI-Ex 3000MB/2400MB
  • Cooling: Cooler Master Masterliquid 240 AM4 Liquid Cooling Solution
  • OS: Windows 10 Home 64-bit
Idle:
  • CPU: 41 °C
  • GPU: 65 °C
Ingame:
  • CPU: 55 °C
  • GPU: 84 °C

CONCLUSION
_
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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.
LatencyMon has been analyzing your system for 0:05:25 (h🇲🇲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): 1150.30
Average measured interrupt to process latency (µs): 5.271220

Highest measured interrupt to DPC latency (µs): 1141.90
Average measured interrupt to DPC latency (µs): 2.280437

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: discordptb.exe

Total number of hard pagefaults 1727
Hard pagefault count of hardest hit process: 462

I have clean installed Windows very recently, used DDU. My graphics drivers and other software are all up to date. I run 3 monitors at the same time, but only game on a 144hz monitor.

Thank you.
 
Hey there,

So, what games are you playing when this happens?

I guess it could be a number of things. Possibly faulty ram, possibly GPU overheating (temps are a little on the high side - causing throttling). Maybe high disk usage, or faulty drive.

For the ram, you can test outside of Windows using memtest86+.

For the GPU, check it's seated correctly, cables are connected correctly. Check all fans are spinning. If the GPU is a few years old, it may be worth looking at replacing thermal paste. Your idle and load temps are on the high side as I've mentioned.

It's possible it's your PSU also. You have a power hungry GPU that on load can use up to 300w! I'd be looking at getting a decent gold rated PSU in your system,

Use something like HWMon/Info, and monitor your system during load/idle and see if there are any 100% usage scenarios or high temps.

You can post screenshots of HWMon with idle/load info and we can see if there's something going on the backround.

You've done pretty much everything else that would be advised: e.g Newest drivers, Fresh OS install. Have you made sure you have the most up to date bios for your mobo? This would be a good thing to do also.

Hello, thank you so much for your reply.
I am playing pretty much any triple A game, most often Battlefield V and Fallen Order for now, but this does happen in games other than EA too.
After posting this question (and before your reply), I disabled Turbo Boost and Hyperthreading from BIOS to see if it would make any difference. So far I cannot exactly tell if it is worse or better, but there definietly still is microstuttering. Do you think I should keep those off or would they not affect this issue? Also, I have started to see spikes in LatencyMon. It spikes up to thousands sometimes. I couldn't recreate the huge spikes but I will include the data anyways just in case.
Thank you again.

EDIT: I had already checked the BIOS update a few months ago but I just checked it again just to be sure, and it is up to date.

I have collected the data:
  • Fan speeds at max
  • Disk usage
  • LatencyMon
  • memtest86+
  • GPU and cables correct seating
  • HWMon

And the results are:
  1. HWMon shows CPU and GPU usages 100% almost all the time while under load; seen in the image below.
  2. Speeding up the fans to full speed did not help.
  3. GPU and cables seating checked.
  4. Disk usage on Task Manager shows around 5% ingame.
  5. memtest86+ ran for 8 hours, got 5 passes with no errors.
Here are the screenshots from HWMon:

Okay, so looking at your data, everything apart from the GPU temps are where I would expect them to be.

Your GPU temp idling at 60c is smacking of something wrong. Its very possible that at high gaming load the GPU at 90c+ is throttling.

My advise is to try thermal past replacement on GPU. Have you confirmed all fans are spinning on the GPU, and it's properly seated?

Your CPU and GPU being at 100% load isn't really an issue. What it tells you is they are actually quite well matched/balanced.

I have checked that my GPU is properly seated and the fans do spin. My theory is that because my GPU is supposed to be ran with water cooling, (it has a built in water-block) the fans may not be sufficient. The problem with that is I do not know much about water cooling, especially on a GPU. I do run my CPU with a water cooler already but I am pretty sure I cannot just attach extra pipes to that, not that I know where to get the required pipes in the first place.
I don't know much about thermal pastes either, instead of the regular CPU install routine, however I will check it out.
If it helps, I would like to mention I have a very loud coil whine issue under load.
Thank you.
 
Coil whine is normally a GPU/PSU issue, or perhaps the PSU isn't providing enough power to the GPU. But that would't manifest itself with higher temps. It could be the fans are failing on the GPU. It might be worth looking into the water cooler to add to the Poseidon.

Hello,
I am trying to change the paste, but don’t know where to go from here, any ideas? I don’t see any other screws.
