I have been running fine for months on my new build playing PUBG and LoL mostly. I took a little time off PUBG and justy played LOL for a month an a few other low quality games. Last week I tried PUBG again and the game started and crashed. Thought it was the game so I reinstalled the game. Same issue. All steam games would crash after being run for a little. I started stress testing my GPUs with Heaven Benchmark and the PC will always crash and rest around the same point in the test. Same with running Fire Strike. This Problem only happens while in SLI. I have been able to run stress test on single cards without the program and PC crashing.
I researched all over the internet and have found similar issues and tried the fixes they use (Usually a power supply) But nothing has made the stress test go any further. Nothing is overclocked. My CPU and GPUs are stock settings.
-MCI MEG ACE Z390 Motherboard
-EVGA 1300 G2 power supply
-2x EVGA RTX 2080 TI Black Cards Running in SLI (EVGA SLI Bridge Installed)
- 2x 8gb G-Skill TridentZ 4000Mhz Ram
I have tried...
-Updating GUP drivers
-Rolling Back GPU drivers
-Uninstalling all GPU driver and reinstalling using DDU
-Rolled Windows back
-Ran both GPUs off separate power supply From rest of PC
-Switching GPU cards around and reseating the cards
All Lighting Software
OC software for GPU
OC softwares for Motherboard
-Disable the: Nahimic Service
Nothing works. Tried all suggestions to be and any ideas i could com up with and all seem to have no effect at all. Still crashes under stress test.
Any other Ideas? SOLVED:
So the issue was one of the GPUs was bad. But I had to replace the motherboard for the card to show this for some reason. Both cards ran alright by themselves on one of my original motherboard. It was not till I switched to the second motherboard. Once I switched it was clear that one card was not working correctly as running it without the second card in the system it would freeze my Bios every time I entered Bios within a few seconds and it had an issue loading windows correctly and would crash sometimes. I do find it odd that I didn't have this issue with the other motherboard but I did RMA the card and the replacement works great by itself and in SLI.
