you can do any of these right now:
Buy 3 antminers and undervolt = 400GH / 500W / 2.7BTC
Has someone developed a method for undervolting the S1? Doesn't this require a hardware mod?
just a pencil mod on R3 (or was it R12?). 8 pencil mods per S1 unit.
but the reality is that underclocking/volting an s1 doesnt make monetary sense right now. In about 2 months it will make more sense if power is a limitation and as power costs begin to catch up to the profit of mining
