1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Antminer Z11 Overclocked Overvolt Release Updated 148-150+ k/sol on: May 05, 2019, 08:33:48 PM
Beta 3 Update:

Luxor admin is telling me that my Z11 is submitting many duplicate shares, likely the cause of most of my rejected shares.

Elapsed           KSol/S(RT)   KSol/S(avg)
21h18m56s   145.63           146.41

Accepted shares: 7860
Shares rejected: 1738
Stale shares: 101

7860 / (7860+1738+101) = 81.01% share acceptance rate / efficiency

HW Errors: 14,586

Fan Speed: 100%

Chip Temps: 82c-86c

I see them on the server
that's the reject reason

2019/05/05 19:31:53 Error Message: {"id":9369,"version":"2.0","result":false,"error":[22,"Duplicate share from miner at address abcdefghijklmnopqrstuvwxyz",null]}

EDIT: I just swapped pools to see if I can replicate the issue.

Just sharing some observations. The beta 3 firmware held over 151-153 ksols for most of the day, but settled back down to 145 ksols recently with chip temps in the 81c-85c with fans set to 100%. Another Z11 twelve inches away running Bitmain 4/23 FW is at 70c-73c with fans at 95%. Re-releasing an April 23 version to cut down on hardware errors at the very least (and any other positive unintended consequences) seems like a no-brainer.
