Title: New to me Antiminer S7 Starts mining then stops Post by: bmukkamala on January 24, 2018, 01:21:47 PM Greetings and Thanks for reading:
I bought a used Antminer S7 primarily to learn about mining. I understand that it is unlikley to prove profitable. I plugged it in and connected to network. All seems fine and it shows up when I login via IP address and for a good 20 minutes seems to hash fine. Then the flashing green light stops (no red light appears) and the miner is no longer discoverable in the IP Address search of my network. Any advice on what I should be checking? Thanks again!

At the current price of BTC (11.5K usd) you should be able to generate around $100 usd per month with an S7 model (assuming your electrical is somewhere near 0.10 kwh). Hopefully you get your money back and start making a profit at some point ;) I would try and make sure your unit is clean. On one occasion I had a similar problem and I took the fans off and outer case off so I could get at the hashing boards. I used compressed air to blow the dust out of everything. There are lots of utube videos on how to clean an S7. Even just going through the process of plugging and unplugging the hashing board cables that go to the controller board might help. Another thing you could try would be to use a different power supply, however, most people don't have spare ones available. It doesn't sound like an Internet problem as you're not able to see the IP when the problem begins.

Hashing board is too hot that is why its stop 2. Maybe your PSU is not giving enough power and your miner stop hashing. 3. Your hashing board is shorted For solution or troubleshoot about this problem you can find it in bitmain support here https://support.bitmain.com/hc/en-us/articles/220872007-Possible-problems-for-Antminer-Troubleshooting-for-S7-S9-L3- Title: Re: New to me Antiminer S7 Starts mining then stops Post by: fanatic26 on January 24, 2018, 09:44:06 PM If the miner is not connectable the controller is crashing. Overheating, overclocks, all that will stop it from hashing but you would still have full GUI access. I am gonna say its either a bad controller or a bad power supply.
