Can I do more hashrate from these?

Hi everyone!
Can I do more hashrate from these cards? Is there any bad OC what I use?
Thx for the help!

Switch to locked core clocks on all, no power limit needed. For lhr cards around 1500mhz is a good starting point, for non lhr cards the goal is to run the lowest locked core clock (not the negative offsets you’re using) that gets you full hashrate.

Thanks, I Try it.
