one of s7 freezes after about an hour powered on - I am trying to deduce what or which component is giving problems. The rigs are currently racked and tied down neatly and taking it out with the PSU will be a hassle. My guess is a bad PSU. I am using the stock 1600w PSU by Bitmain. Anyone had this situation before, comments pls, it would save me a lot of time....
Try using another PSU from a close by machine. What are your temps?
temps are normal low 60s and overall cage temp also ok.
Yeah, swap PSUs on it and see if it still behaves erratically. It could also be your controller, I had one that was wonky like that. You could almost set a timer and countdown to when it would die. If so that's hopefully still under warranty.
Let us know what you find in case someone else has the problem.
