I can confirm that PPNLS payouts with Antpool is not working but PPS is. Also my Freq is 643 & I'm getting an average of 15.4ksol
15.4 KSol = Almost my 3 rigs full of 1080TI and Titan Xp, but less power efficient :-)
Significantly, I'd estimate that overclocked z9 is running at under 500W.
Do any of my fellow Z9 miners know why? , I am set up on Antpool mining Zcash with my Z9, strange the payment status is showing "Paying" all day and not paid out. have you any idea why its doing that?.. Thank you
