Thanks. I will look for a drop and order again. I was able to set up some at my friends office.
I think I can run 4 at his place with under volt and down clock . I can get 600 gh and 800 watts.
He shares a building 4 ways and splits the power bill 4 ways.
so I am getting power at 4 cents a k watt in his place vs 16 cents in my home.
my limit would be 4 units in his office but at 4 cents a k watt I smell roi.
That's a nice price for electricity if you can get it. What would be even better would be if the S2 came down to a more realistic price of 2 to 2.5 BTC - then we could all save on elecricity bills...
