I probably have the same card, exactly the same hashrate, but 115 watt power consumption, 5 Celsius less, fan at 37 % but running in windows, because I was unable to fine tune power in Hiveos.
Whats ur memory like? maybe I'll try ur setting and see if it works better?
you are on the same core and memory setup that I used when I was in Hiveos.
Now my memory is down to 1258,(windows 2516 in Hiveos) because the sweet spot was there . PL etc obviosly have changed
