my question would still be Taserz. On GitHub I can see that there are several versions available for example: bmminer870, bmminer880, bmminer890, bmminer910, bmminer920, bmminer930, bmminer940, bmminer9v. What are the differences between them? Currently I'm using bmminer940 at 700mhz speed. Is that right? 

I tried custom firmware. It works perfectly so far. Thank you so much for taserz! (Antminer S9i - 14TH\s)

okay. I still have a question. I can not connect via the Putty program to the machine. It does not accept the password as root is root / root and is not good. There is a port number I do not understand why it would be a local network.

okay. I can see multiple versions of GitHub (bmminer870, bmminer880, bmminer890, etc.). How do I change the TH ratio? Should I set the Volt or Mhz?

okay. Can you send me which version to put on my machine? What can I expect to increase performance? is there a chance to keep the temperature display?

Hi there. I would have an Antminer S9i factory 14TH version. I want to operate at 15TH clock.You can help me in taserz? I need a firmware that does not steal your performance thank you in advance.
