S19 and S19j overclocking

Does anyone know of firmware out there for over clocking the S19 or Z15s series of miners

Braiins has a beta for S19 autotuning, I don’t know how much, if any, it overclocks

Marc with asic.to has one. His group was the first one to write new firmware for ASIC machines.

The website says they only have S 17‘s but shoot them an email or give them a call because they do have firmware for S 19‘s. For the S 19 Pro he can overclock it up close to 200 th/s if it’s in immersion or in Siberia on air cooling. But you should easily be able to get 140 with air cooled.

He’s a super great guy and has probably forgotten more about ASIC tuning than most people will ever know.
