not really dropped. infact i had to increase powerlimit as it became unstable,

https://ibb.co/4NMqHk3Hi AZaman,
we are sorry, but maybe we did not understand exactly what you consider to be the problem.

With --oc1 we expect that the cards with less power would benefit more.
Did you try running miniZ without --oc1? What was the difference?
Could you paste here right the beginning of the log? (Right after "******** miniZ v1.2m ********")
Cheers
here is the beginning of the log:
