I recently bought several antminer s4's from zoomhash and have them set up, however I need to underclock a few to be able to run them in the same room. The power breaker trips with the last ones running and I can't run them anywhere else, so they are currently just sitting in the room. Does anyone have a bit of information on how to underclock them, or a chart detailing the hashing to power rate?

Thank you for the help.

you need to post in the s-4 thread

https://bitcointalk.org/index.php?topic=796839.0

most likely the mods will move you to this thread anyway.

I never owned and s-4

I owned
s-1
s-3
s-5

You need to set frequencies but I am not sure about that unit.
