No sorry, just changed card voltage...
Wow 300 watts reduction?!?
How low did you set the voltage? I set mine to 780 as a test and while the temps run lower & fans are little slower/quieter I'm only seeing very minimal power savings at the wall for some reason.. As in at fixed 450 mhz frequency, 4 watts per card so ~16 watts less reading on my kill-a-watt:
Chain[J4] set working voltage=780 [54] orignal voltage=930 [0]
(The typo is theirs in the code.. lol)
I got the fans tweaked exactly how i like them now! Instead of the annoying way too fast or the ramping up & down over & over, I can basically now set a goal temperature & the fans auto-tune accordingly. To me this makes a lot more sense than the nonsense they build into the antminers. Wow that code of theirs on github is a mess.
But yeah it'd be cool to know what you changed.
Thx
