Thanks guys. Appreciate the help. Yeah, this S9 was brand new sealed, just plugged it in this week and getting higher than expected stats I've been mining with many L3's for a while. Just wasn't used to seeing that many discarded shares. So far today, 11 hours on, 2575 accepted and 19530 discarded with a 4.3 utility and 115HW.
I understand the machine working on stuff that is already been solved/old news is discarded. Didn't know what to expect.

Thanks again.
