Z9 working with nicehash. Had to set the difficulty manually. Still playing with that though.
How are you setting the difficulty manually?
in the password field where you add the stratums under the control panel menu you add D=yourdesireddifficulty
i guess you have to test it as no sources are available for it yet, try several digits like 1000, 5000, 10000 and so on and see how it works out, than fine adjust.
What kind of results are you getting with various difficulties? At the standard, I was getting around 2/3 my hashrate, and about 40-50% rejected shares, so I just said screw it and went back to antpool for now (because I have work to do), but if you're seeing better results I'd be into playing with mine tonight...
