About under voltage, the marking of "11.8-12.2V" means this miner will have a 3.65T (+- 10%) of the performance, we test it under this voltage. You can run it under a 11V PSU, and will get a better efficiency performance but slower speed. The hardware and software is fully support this case. but I think the lowest voltage is ~10V.

That is excellent that it can be underclocked & undervolted. Do you have a table of Clock Frequency, Supply Voltage, TH/s & J/GH ?
