So! me and my friends got each like 8 antminers S5, different batches, using a Corsair CX750M, HP DSP 800GB and DELL N750P on the miners.. we all use different routers, switchs, firmwares, but we all suffer from the same thing.
One of the boards on the miner will turn off for about 6 minutes, and then turn on again, its always the left board if you look the miner from where it pulls air. it happens in ALL the miners! not even one saves from this problem!
Its random, so in the morning it can happen to 2 of them, and in the afternoon to 1.. it can happen twice in 24 hours to the same miner.
How did i find out about it? one day i was checking the miner Hashrate 5 seconds and realized it was hashing under 600 ghs for 6 minutes and then went back to 1.15th, you can even see the red led on the board turned off!
