PyTorch CUDA Errors on Ubuntu 22 with RTX 3090 Ti x2

Actually I did so at CUDA errors with CUDA 11.7 + dual RTX 3090 Ti - PyTorch Forums

However, as I explained in this post, I feel that the issues are something more like fundamental (RTX 3090 Ti and/or dependencies) rather than caused by the specific script, and that’s because I made the post here at first.
e.g., this is a similar case, and people experienced or suspect that the card was/is broken.

Are there any stress tests available to make sure that the GPUs (NVIDIA RTX 3090 Ti x2) are not the root cause of the issues?
I am still looking for help.

Thank you
