I tried to apply with my 2 x rtx 2080ti stack I experienced more stability but still bsod occured randomly…
:(
Maybe I should change my Asus x299 W mobo?
Test your system with one GPU at a time. Can you test GPU1 and GPU2 on 2 PCI-E slots (e.g. PCI-E1 and PCI-E2) as follows:
- GPU1 on PCI-E1, check for stability
- GPU2 on PCI-E1, check for stability
- GPU1 on PCI-E2, check for stability, and
- GPU2 on PCI-E2, check for stability.
If one of the GPUs performs without any issues on both PCI-E slots and the other GPU has issues on both PCI-E slots, it's most likely a GPU hardware issue.
If both GPUs works fine in one PCI-E slot and cause BSOD in the other, I'd continue testing one GPU at a time in each of the remaining PCI-E slots, to ensure I've identified the defective PCI-E slot. If you identify a particular PCI-E slot that causes BSOD, it's most likely a motherboard hardware issue (e.g. bad/cold solder).
If all tests with one GPU at a time pass successfully, I wouldn't replace any hardware, I'd contact NVIDIA and ask them to look into the drivers, providing your hardware configuration.
In the past, I had an X99 mobo and an X299 mobo replaced twice (!) because of BSOD and because NVIDIA's tech support was blaming the motherboard and ASUS's tech support accepted it could be a motherboard issue (!!) and what I found was that it was NVIDIA's fault in the software drivers.
It's still unclear to me why NVIDIA recommends that we use a third-party utility to enable MSI, while NVIDIA could enable MSI upon installation of the software drivers.
I hope you find the above useful.
