NVIDIA drivers are version 430.86, GPUs are any of GTX1060 6GB or 1080Ti
For Nvidia the ProgPOW support requires two additional DLL files. You need to download the archive
PhoenixMiner_NVRTC_Windows.zip from
https://mega.nz/#F!2VskDJrI!lsQsz1CdDe8x5cH3L8QaBw and extract it into the same folder as PhoenixMiner.exe. We didn't include these files in the main PhoenixMiner archive because they doubled its size and are needed only for ProgPOW mining with Nvidia cards.
