Does this work for Antminer S17+
no, not yet. but i think soon. vnish (another developer) is already working on version for S17+ release mid february
As far as i know late march/april hiveos is releasing their firmware for S17+ . I seen few firmwares been advertised already 100TH/s at 4200 watts, but really dont know how legit are they. Will need to test them.
