Hello,

I want to control in a linear way the power of my miner from 0 ( no mining )  to Pmax ( max hashrate ) :

1- Hardware modification of internal power supplies of chips  on hash boards : If I get a hardware solution to undervolt / overvolt supply of each chip , do you think it will be OK to control power ?

2- Custom firmware that control the hashrate : is it possible ? how it will work ? I heard about Braiins firmware that can do that , but how it works really ?

3- disconnection of hashboard supplies ( 12V) : If I add a switch on the 12V , do you think it will be possible get 0 or Pmax only by switching ?

Thanks
