Spondoolies SP20 Using a voltage setting of 0.62 my SP20 was able to get 1.2TH/s while using 640 watts (0.53W/GH) and exhausting 124 degree heat.
So if SP-T is going to compare the SP20 to S5, can we get S5 pricing? They are down to $353 each for a 2 pack shipped to US. If you are changing, then I want to change my order to a mini-farm
