I think you should rework the way you do miner exit on gtx1080ti's with straps applied. I found a trick how to fix your timings and than run your miner without strap management.
It keeps high speed of modded timing and doesn't crash system on exit.
Ok I will restore settings at exit.
14.0 - 14.2 versions do not detect NVIDIA GPUs on mixed rigs (AMD + NVIDIA)
Install latest drivers or use files from "cuda8" folder (redownload v14.2 if you don't have this folder).
