Hi i have 2 Whatsminer m3x.

First has i think latest fw from 18.01.2019 which is good adn fun speed is ~3700 that is ok.

But second ASIC has old fw from 30.05.2018 and on same temp has ~1000 more fun speed than first always.

Both miners are in same room, the distance between these two is about 30cm and both are in a ventilated room.

I need latest fw for secon miner like first because lower noise, better fun control and better efficiency.

I cant find this fw for my second miner.

Both miners were purchased as used.
