I have a s9 that has a failing hashing board. This s9 is an early 11.5th model, but I have a hashing board from a 13.5th unit to use as a replacement. I plan on learning how to flash a new os like brains to the controller. My question is will the os be able to handle the mixed batch boards?
Very likely it will work.
I have mixed and matched s9 gear.
But the oldest s9 units have the bigger two piece controller I have not used those two piece controllers with brains.
so i am not completely sure.
