I'm getting the following:
1080ti Aorus         PL 80, Core +60, Mem -500 = 49.8-50.5 MH/s
1080ti MSI Gaming PL 60, Core +100, Mem -500 = 46.8-47.2 MH/s
1070 Gigabyte       PL 90, Core +105, Mem -500 = 29.5-30.5 MH/s

This is great compared to other miners, no crashed so far in a few hours on 2 rigs.
However I am experiencing the same issue as others with the shares sending, after 1h30 I only send a share every 2 minutes.
