Question Why does my 2080Ti crash in every game if I set the POWER TARGET above 50%?

[GDR]

I bought a few years ago a system with a 550W PSU and a GTX 1070 GPU that I was using with a 27 inch monitor. I sometimes had system crashes with a blue screen.​

Anyway, after a couple of years I sold the GPU and PSU and bought a Corsair HX850i PSU and upgraded my GPU to an ASUS dual OC 2080Ti and had no more PC blue screen crashes, but sometime, very rarely, games crashed when there were very intense scenes.
When I upgraded the hardware I did not reinstall windows.

After a year I upgraded my monitor to the 144Hz LG 34GK950F and since then the crashes have increased so much that every game crashes after a few seconds of gameplay.​

The system doesn't crash, only the game crashes to desktop.

​

First I thought it might be the high temperatures, but most games run under 70C. And the dual fans rarely run above 30% of capacity.
So I limited the temp to 70C and there have been no more crashes. If I go 71C limit all games crash after a few minutes.
After some time I played more with the settings and found out that the issue is the POWER TARGET. If I set it to 50% there are no more crashes. I can leave the temp to the 84C default limit.
What does this power target mean and how can I fix the problem?

For example in Divinity Original Sin 2 if I set the maximum FPS to 60 I get crashes after an hour or so of gameplay without any power targer limit. But if I crank up the FPS limit to 144Hz it crashes immediatly unless I set the GPU power target to 50%.
This happens in absolutely every game. From non demanding games like Two Point Hospital to Control and Gears 5.

Thank you very much for the support and I look forward to your reply!

Maybe the monitor isn't set all the way up to 144hz? Not completely sure, but I know my monitor had to be manually adjusted.

If you are positive about monitor being the issue, try the stuff I posted earlier (turn freesync off, lower resolution, or change the interface from dp to hdmi).
The FPS will surely go up but we are testing if the card can sustain 100% load at 100% power target regardless of resolution right?
I am skeptical about the monitor being the issue, but it is possible.

I tested OCCT with a hdmi cable and no freesync (I think it isn't supported via hdmi anyway, only with DP 1.4) but the issue remains. I ran the test at 1920*1080. I haven't switched the resolution in windows. Sometimes the whole screen would flash black for 3-4 seconds than the image would be back.

I kind of refuse to believe that the GPU is busted. I have never seen artifacts. And even at 50% power target I still get over 100 FPS in most games. The only exception being Control. I struggle to get over 60fps constantly on ultra settings 3440x1440 resolution and ray-tracing. I'm sure it's because of the 50%power limit.

You said "temps at max". What are your CPU and GPU temps while gaming? Install MSI Afterburner and enable the overlay.

I don't think I've ever had the GPU go over 80C. Usually it's under 60. Depends on the game. Lately, Gears Tactics on ultra 3440x1440 goes between 60 and 70C.

I don't know what you mean and how to do that. When OCCT test begins it shows over 156 fps, but then it drops to 0.5
Should I limit it somehow to 144. Maybe via ASUS GPU Tweak? In advanced settings there is an option "Frame Rate Target (FPS)", by default it's 0, but I think it means unlimited.

Early batch of Samsung GDDR6 had a defect that caused issues and required memory replacement. There is a whole bunch of defective 20xx for sale on ebay because of that. Does not seem to be your case though.
Regardless, I am somewhat positive on blaming the graphics card at this point. RMA it if you can.
P.S. Omit all your findings and state performance issues and crashing in the ticket.

The settings to do this vary from monitor to monitor. I have a Sceptre monitor, so I don't know too much on how different your monitor is from mine. I just don't know how to change it on your monitor, as I have never used one of that brand and model before. Personally, I would look onto other forums, youtube, google, and even the monitor instruction pamphlet to find out.

RMA it if you can.

When I go to the ASUS website and write the serial number, it says invalid serial number. It's written on the card and in at least 3 places on the box. 😓 I'm gonna call them tomorrow.
