I have 2 Antminer S1's, and they behave differently when I Apply and Save a new Miner Configuration. The first one kind of shuts down for a minute or so and quickly resumes working with no beeping. The second does the same thing, but it takes a minute or two longer, and it beeps almost the whole time.

I know it's not the best description, but can anyone tell me why the difference and how to make the second one behave like the first? I bought each unit from a different place.
