Finally tried out some of the other modes on the Apollos in the last few days.
Had a very delightful and surprising discovery.
In Eco mode.... I was getting 2 th/s @ 76w per th/s
in Balanced mode.. I get 2.5 th/s @ 64w per th/s

So, not sure why but balanced mode actually offers better wat per wat performance for me.
Also, it was a more substantial hashrate increase than I expected too, with 25% performance gains over eco.
So, if your out there just chillin on ECO with your miners, I recommend trying out the other settings and seeing what you get.

Same here. There isnt much in it between ECO and Balanced. I think ECO was more for keeping noise down. Balanced is the best for me really 2.5Th at 66w Th/s. ECO was around 62w-ish for 2Th.
