thierry4wd some miners have been seen from factory with mixed hashboards, don't always rely on this method. I have no idea what using the wrong eeprom info could cause...
BitMaxz endusers are not going to do backups of their eeproms unfortunately... That is why bosminer never touches them.
precisely, but I have the habit, many times! and as I develop firmware, I know exactly how they work, I affirm with certainty, that it has no risk ...
in the firmware, there is a file which lists all the possible hashboards for this model, in this specific case we talked about the S19Jpro, there is also another file which lists all the possible speeds (100 / 104 / 110th for example ), then , the PSU models ...
if only one of all these parameters does not match, then the miner will not start!
flashing another EEPROM has no adverse effect ... only 2 solutions, the miner will simply not start, or it will work a little faster or a little slower (frequency info)
