Can somebody please tell me if I get this right:
The difference between the fixed frequenc firmwares is the voltage, right? So If I load the 650M firmware on a S9 with stock 14TH, it will assume it has good chips and give them LOWER voltage than the 600M firmware, right?

So could i just load the 650M firmware on my S9 and check what frequency it accepts?
Problem is that as soon as I load the fixed frequency firmware, the temps show above 100°C. But i think the readings are not right...

Any advice?

The readings are right, i have a lot of S9's and i loaded 650 FF FW and the temps went crazy.. some showed 82 temp but in the firmware it said display upto 82 only so god only knows what the temps were.. for that extra 1.5TH it aint worth burning your boards..
Just my opinion.. tried and tested.. i have auto freq on all of mine.. loading the 650 FF FW is for very cold climates
