Try phoenix miner with the following settings: : -ethi 8 -tt 54 -cclock 1300 -cvddc 750 -mclock 910 -hstats 2
I make 52.65MH/s with 93 watts powerdraw and gpu hbm temperature 70 degree C. You can try with higher -tt to decrease the fan speed. 54 works for sure and is too safe.
what phoenix miner version?
