You set your "diff" manually at Slush to 1664? or did you tell Slush to auto select? I'm talking about settings at Slush for all of your workers. Not settings you actually did on your S4
I set it to 1664 for the S4. Seems to work best with less rejects and less variance too.
PS. oo... I really hate the 360 seconds wait....
That did it...
I rebooted so i would not have to wait 360 seconds to see best shares on the S4... IF that was what you were referring to. Not sure.
