Hi zer0k, did you have any issues setting -ac with the 1080 ti? I have a script I used for my 1080's last year that set max mem/gpu clocks, but it gives an error that looks vaguely familiar (running the shell as admin already, so it's not that):

Setting applications clocks is not supported for GPU 0000:01:00.0.
Treating as warning and moving on.
All done.

Any suggestions are greatly appreciated.
