Good ideea, i didn't do that.
I'll try it as soon as possible ang get back with an answear

I've tried to put it in antpool, still same response. It's 4,73Th/s so the freq should be 700M, the firmware should be correct.
At the moment i'm running it on HP 1000w PSU, they are completely fine, i've tested them on another S7, working fine.
Thanx for the ideeas.

Any ideeas in order to solve my problem would be welcomed.

Thanx, but i still face the same problem...
