I have one small klondike 5-6Gh/s (donnu how to overclock it I bought first one to play with it.
When I restart first time it drops half speed, when I restart again it wont start up, only shutting down it and disconnection from electricity helps...
And last two days, one of two S1 after booting cold simple don`t start to mine (not showing speed in gui) after I change speed in file and rebooting it starts again. Simple restart don`t work. Working temp. 43-45c.

I forgot about this option, because I did not like it. Not taking in mind that it will ship in 20/9 maybe, I`m located in eastern Europa and fastest I something receive from China is 3weeks, sometimes even almost 2 mount with economy shipping.
But, what there is in package, how I understand I can buy russbery pi those boards to run and not disassemble S1. And mine idea what I concern about is that S3 has shell what directs air. S1 does not, its huge difference in my mind.

It seems because of difficulty is going up and in the same time now bitcoin price is going down AntMiner S1 will be worthless to run sooner rather then later...
Only good possibility is in cold winter to overclock them if your electricity is "free"... you can use them as electrical heater in the same time...
