Up to the documentation of CUDA toolkit 12.2.2 ([Release Notes :: CUDA Toolkit Documentation](https://docs.nvidia.com/cuda/archive/11.2.2/cuda-toolkit-release-notes/index.html)) we had the following requirements:
Documentation of toolkit 11.3.0 ([Release Notes :: CUDA Toolkit Documentation](https://docs.nvidia.com/cuda/archive/11.3.0/cuda-toolkit-release-notes/index.html)) says:
and 11.3.1 ( [Release Notes :: CUDA Toolkit Documentation (nvidia.com)](https://docs.nvidia.com/cuda/archive/11.3.1/cuda-toolkit-release-notes/index.html)):
whereas the latest documentation ( [CUDA 12.0 Release Notes (nvidia.com)](https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html)) says:
I’m concerned about the lowering of the requirements for toolkits 11.2.\* that went from minimum driver versions 460.27/32.03 in documentation 11.2.2 down to 450.80.02 in documentation 11.3.0 and after.
We have V100 and A100 cards with Driver Version: 455.23.05. Using toolkits up to version 11.1 works fine. Any attempt to use a toolkit from 11.2 or above fails with cuda error 222 (cudaErrorUnsupportedPtxVersion), what makes me believe that the actual documentation is misleading but was correct up to version 11.2.2 ([Release Notes :: CUDA Toolkit Documentation](https://docs.nvidia.com/cuda/archive/11.2.2/cuda-toolkit-release-notes/index.html)).
Note that this applies to the case where you want to generate PTX (e.g. with -arch compute\_80 -code=compute\_80 for an A100 card) to be JIT compiled. Generating binaries (e.g. with -arch compute\_80 -code sm\_80 for an A100) works fine with both 11.1 and 11.2 toolkits.

R455 is EOL according to

Yes, I saw this one. However there is no such deprecation notice in the release note of the 11.3.0 toolkit. And, if I understand the version numbering correctly, it’s a bit awkward to step back to a lower version than indicated at release time.
