Hello all,
I have a Bitmain Antminer S5 that hashes properly for 1-2 minutes. Once it reaches it's maximum hash rate it stops hashing and begins beeping. There is plenty of power and a fan is connected to the PCB controller board and shows 1,680rpm. Temperatures are in the mid-60's. It has a constant internet connection and I can see the 1-2 minutes of mining in the pool.
Has anyone heard of a problem like this before? Any recommendations?
Hmm. Mid 60 is a bit high, its probably unlikely but it would do that if it was overheating, but it should probably resume later on.
I'd try with a different PSU to be sure its not the PSU failing.
Then i would run it one board at a time to see if its a board or the controller. Assuming its not the PSU.
