Try the following (replace your pool address and change coin address)

sgminer -k skunkhash -o stratum+tcp://sigt.suprnova.cc:7106 -u B59jAuXTHv6GEww6K7AGg6DTjwkm2qiUh9 -p x -I 20 -d 0


Create separate bat files for each card you're using - just change the d 0  at the end for d 1  then d 2  etc.

I'm having to do different intensities on different cards.  If it still crashes reduce the intensity right down to 10 and test again.

It does work on nvidia, but you may find you have to run a different bat for each card and different intensities (I 20 part make it I 10).

On my 1080ti I'm getting 38mh.
