Strange 1080 Ti display problem

[Shineful]

I have been pulling my hair over this problem for the past few days, I finally decided to seek help. Hopefully someone will have an answer.

 

I bought a used Gigabyte aorus 1080 Ti (non extreme). It was used for mining and was underclocked and undervolted according to seller.

 I installed it and used the latest drivers 441.87.

 

My monitor is a 75 Hz freesync display. I have been experiencing frame drops/stuttering on my desktop. Whenever I scroll, move windows around etc.

I decided to try the UFO frameskipping test. 

 

Result was as follows: 

The frame rate varies anywhere from 65-75 erratically. Gpu clock and memory clock stay at 139 Mhz and 101.3 Mhz. I tried to turn freesync off, put display in 60 hz mode. Stuttering persists. The test now shows frame rate varying from 54-60. Everything 2D still stutters. As seen when running at 75 Hz..the gpu is more than capable to render more than 65 frames..I thought 60 Hz would fix my problem.

 

Now here is the interesting part:

 I tried playing a youtube video, gpu clock goes to 601 Mhz. Video plays smoothly. I try to move windows around..all smooth! UFO test stays at locked 75 fps on 75 Hz and locked 60 fps at 60 Hz. 

 

 

Over the course of the past few days, I tried to DDU, try various driver versions ranging from 399-441. I even tried the clean drivers without RTX. I'm totally lost.

 

What gives? Is my gpu defective? What else can I try? FYI, in games it is perfectly smooth! running all on all ultra and everything, no stuttering, nothing.

Any other 1080 Ti owners having the same problem? Is factory idle clock too low? 

 

 

SOLVED. See solution below.

If it runs stable in games it shouldn't be defective, you could try a software like asus gpu tweak and enable the '' 3D clock always on'' setting, but it would consume much more power then in idle. 

But first I would check if the BIOS was flashed.

Bios version number is same as latest version on the gigabyte website. Seller also told me its the original bios.

I guess 3D clock will be my last resort but I feel like I shouldn't have to do that just for a smooth desktop.  Do you have any other suggestions as to what I could try? Thanks.

Hm if the BIOS is allright, I guess it would be a driver issue, or maybe some windows power managment. 

My card clocks imideatly to 1600mhz for a second even if I just open a Firefox instance. If I watch yt 720p non full screen my card clocks just up to 155Mhz and is 8% used what is just 1% more than usual idle even at that clock. 

What GPU Usage do you have in idle? 

Did you install a fresh Windows before mounting the GPU, if not, that can cause driver issues. 

You also could try stress testing the gpu, see if clock is stable at full memory and gpu load.

I already tested with furmark 10 mins, OCCT, unigine heaven 30 mins, MSI kombustor 30 mins(0 artifacts). Temperatures are pretty nice, mostly hovering around 62-68 degrees. ambient is 26 C.

 

No I did not do a fresh install. I was using an RX 570 before. However I did use DDU. Shouldn't that be enough?

[Plermpel]

I never used that software but clean install is allways the best choice.

If I scrub arround Windows dwm.exe shows about 10% GPU load in Task Manager.

I assume that some deep parts of Windows are still used to your AMD card and didn't really get the upgrade, so they don't communicate to the driver to crank up the clock speed due Window scrubbing arround.

I'd really recommend a fresh Windows install, if you have two hard drives thsi isn't even a big deal, you just leave all your steam library and all data on the second Drive copy your whole User Folder from C:\Users to the other Drive, clean up all the crap out of the folder, and then you just have to reinstall Windopws and the software that was installed on C Drive, if you copy your User Folder be shure to not replace double Files on the new clean Install, just merge all the folders so all the System Files stay clean and new.

If you don't have Tones of Software installed on the C Drive that usually takes you a few hours to get everything back to normal and make shure you download all the importend drivers before, or it can be tricky if you want to download drivers on clean Install with WiFi but got no WiFi drivers.

 

Have you ever done a clean Windows Install before?

Yes, numerous times, I just find it tedious to reinstall everything, restore all backups and settings. Thanks for suggesting it though, I will probably do that if no one has another suggestion. I did run into an error in Event viewer where dwm.exe crashed. (twice since the last 3 days) You might be onto something.

You did? What Errors? Can you post the reports?

If it's a DLL Error I could just give you that DDLs cause I have a 1080Ti that should match, or you can try running sfc /scannow in command promt, sometimes helps.

Also would be interessting than if your Windows is also laggy if you run save mode?

dwm.exe crash. faulting module is ntdll.dll. 

already ran sfc /scannow, returns no errors.

There are several NTDLL.DLLs what CPU are you running? If you run Intel that could cause a system crash but if you run 3rd Gen Ryzen I could send you the DLLs

 

Full Crash Reports would still be interessting

SOLVED. 

 

I'm glad to report that the reason was because of power monitoring in GPU-Z and afterburner. My monitor is running perfectly now. If anyone has nvidia gpu and is experiencing microstutters, in games or even frank stutters on desktop, this is the fix:

Intressting I am monitoring Power without a problem in ASUS GPU Tweak, but I'm glad you found the problem.
