Thank you for posting, let us know if you keep it at 750 and how it responds. Also, I see you are on MPH. For some reason my Z9 is earning on MPH, but it is not registering on the dashboard, graphs, worker page etc. Did you have any similar problems? I have successfully mined using the Equihash switching, BTG, ZEN, ZCL and ZEC. I am generating coins but no record of my miner at all on the pool.
For equihash auto switch, gotta add the workername to the individual equihash coins for it to show. I have the same issue with my GPU rigs.
Are you sure BTG is working on MPH? When I look at the MPH Auto Exchange supported exchanges, it doesn't look like any of them are working with BTG:
