I pretty much run my machines clocked down to save power.
16,400 @ 800W 1-2v
Today I thought I would fiddle around a bit.
Running at 19,300 @1100w 13v(bitmain stock)
So its an increase of 18% in speed and 37.5% increase in power consumption. Its not worth it!.
Power mode Im at 500-525. Some boards will run 550 but I start creaping to 1250w. I have run it stable at 21GH but its not worth it.
in quiet mode I really have to fiddle with the settings but its mostly around 450. one board wont run low volts unless i put it down to 400.
