Hi,
hope someone can help me.
Yesterday one of my S7 suddenly stopped hashing and started beeping.
When I restarted it one of the has boards instead of showing oooooo just showed ---------, what the miner would do is that it started hashing for a couple of minutes and then stopped.
They miners are in a controlled environment with several other miners with constante temperature of 55 C.
Also tried with all 3 hashing boards connected change the frequency to 250 and same thing happened.
I tried to test connecting just one board to see which one was not working, with just one board connected it starts hashing normally for a few seconds, then the miner restarts as usual and when it comes back up the temp on the hash board is 95 so it stops hashing.
I tried with the second board, only that board connected and same thing happened.
Tried with different terminales and cables on the PSU.
Haven't tried with the last board since I don't want to damage them.
Could it be the PSU? Any advise would be greatly appreciated.
Thanks

I would try upgrading to the latest firmware version. If that doesn't fix it, then consider sending it to Bitmain or Bitmain Warranty if you are in the U.S.
