My 1060's have Samsung memory. I am getting 25 MH/s mining ETH.

Linux settings:
Core: -200
Memory: +1850
Power Limit: 75 watts

Same hash under windows. The only difference is when using Afterburner I set memory +925 (half the Linux setting).

I tried 1060's with Micron memory, was getting around 22 MH/s. Cards with Hynix memory were even worst at 19 MH/s.
