I have a RTX 2080 Super (https://www.gigabyte.com/si/Graphics-Card/GV-N208SWF3OC-8GD#kf) it is a little over a month old now and suddenly i have been having problems with it. When playing more demanding games (Deus ex mankding divided, Just cause 4, even outwards...) after a few minutes of playing (5-10) all monitors go black and GPU fans speed up to 100%. Then i have to do a force restart PC (holding the power button). Sometimes i get a blue screen with error message "video_dxgkrnl_fatal_error". GPU on 100% utilization ran at about 75°C, i also have a big case with a lot of ventilation so i don't think that would be a problem. I also played Control and skyrim before Deus Ex and had no issues with those 2 games, also playing Legue of Legends and have no problem as well.
I have tried the following things:
-Using DDU to uninstall driver and reinstalling it. I tried new nvidia drivers as well as 3 months old ones.
- Turn off any kind of OC
- Resetting motherboard BIOS
- Reinstalling windows 10
- Increase Virtual Memory
- Upgrade my PSU to 850W
- Re plug and change all the cables in my PC
- Changing thermal paste
- Played games that uses Vulkan instead of DX12 and found out that the crash does not happen. I played Read Dead Redeamtion 2 for about 45 minutes all settings cranked to max and there was no crash.
- I also ran some benchmarks (OCCT, MSI kombustor) with GPU and VRAM stress test. Runned for about 30 mins and there was no crash.
- Tried installing an old version of DX and it didn't help
- Reduced the power limit of GPU to 80% and after that i don't get any crashes.
My specifications:
- i5 8600K
- AIO liquid cooler
- Asus prime Z370 A
- 16GB gSkill tridentZ
- 250GB nvme ssd
- 2TB HDD
- Evga 850W PSU
- RTX 2080 Super
- Windows 10 version 1903, build 18363.720
