Re: Running different frequency S9 hash boards in same miner...possible?
Not only possible, the auto-tune almost makes sure of it! 
The rated speed is the sum of the boards in the miner, the boards alone don't know if they're in a 13.5 vs 14 version.
Do it, many members here swap boards around to keep a miner fully operational.

Awesome, thank you for the reply, that completely answers my question as all of my units are auto-tune!
