Mining with 3080 & 1660S

Friends,

I have a rig with 3x1660S and 1×3080. After tuning, I am getting about 70Mh/s with 600Watts power consumption with all 4 cards. I tried to look for some YouTube videos which claimed that 1660 can get unto 16Mh/s but my throughput is limited by 11Mh/s.

​

If you are using 3080 and 1660s, Please share your stunning parameters.

​

PS: I was mining ETH earlier and I was getting about 180Mh/s.
