Wow .. I have had a s9 for a couple of weeks now. been running it on slush. I was going to move it over to Kano but will keep it on slush after all the negativity about the s9 here.
FWI we would all have been better off just buying bitcoin instead of buying any of these OVER priced miners.
Best of luck to all.
Sounds like your S9 is fairly new if you bought it new. There's a pretty good chance it is a v2. You can tell if you go to System and see if the BMminer Version is 1.x or 2.x
