The best thing about this firmware for me is the fact that my miner runs despite the front fan sensor being faulty. Previously, it would shut down because the fan is not sending the correct signal to the control board. Now it runs and ignores that (which is perfect). The fan works 100%, speeds up, slows down, but doesn't send it's speed to the controller. I don't have to replace this expensive $80 fan any more now, it just runs.
Glad it helped you out
I rolled the dice and flashed my D3, i have to say, this firmware has a lot more proper-like features than Bitmain's stock crap. Kudos there. I was wondering about the voltage, are you using numbers because you can't actually read/tell the real values?
