I was a bit surprised that the Antiminer S19 does not have performance configuration options (like S9), for frequency/voltage, for lower or higher performance (I'm especially interested in running it at lower power).
Is there some trick for this?
Or are there alternative firmwares supporting S19? (Braiins, HiveOS seems not)
I did some search, in this forum too, but found no answer.
S19_95T, original firmware Dec 11 2020, updated to April 11 2021 (no visible differences).
