put a new update management program BaikalMonitor. Two days one of the Baikal began to glitch ( became often turn on the fan). Turned off, turned on and as wrote above Hashrate av showed 44 GH. Within a few minutes fell to 16 GC. Then another few minutes went down to 14 GC. And smoothly fell to 10.14 GH. Neither of which is not pierced. The question, maybe already from the factory to have the firmware and how to find it? But you can get to see the traffic from each machine. Possible hidden traffic, that is, the main to another address..
