I like the miner but it eats up too much electricity 2kw for only 256MHZ that's crazy power use
Seems to auto clock itself based on temps to always achieve hashrate, so the higher the ambient the higher the power consumption. Mine is about 2500W @ 35C.
Have you tried putting in a cooler environment? like 15c or less? it's help a lot if you could show the graph of consumption/temp
