yeah it is very likely dying on you.

and most likely it is a board or two.

not the controller.

definitely possible that the board is dying but for now it seems to be working from the local side, so i was wondering why the pool side hr hadn't moved. but it's slowly coming up now (>10.5TH/s) so the number on the workers>>workers page of kano.is must be a little bit longer average than what i expected.

Your hash rate can take an hour or two to level out.
Of course that can be high or low on the pool, but it takes a while to converge.

Also, of course, if you were almost continually mining, i.e. the stop+start was short, the 1hr hash rate will take longer to average out since it's not 'starting from now at zero' but instead averaging out the longer running lower hash rate with the higher new hash rate.

Hi,

I have had a very similar experience. Had a bit of a power spike and middle board on one of my s9 just stopped hashing. Sounds exactly like your board. Everything working except no hash showing in the pool and board just showing no hash, (so kind of not working, but working!).

I moved controller cables from working boards to the dud one to see if that helped...but that did no joy Cry

. I left it running for a couple of days but that did not help either.

Have just, (today) sent board off to Bitmain Warranty USA. I am in UK so may be in for a long wait. Still the s9 is still pushing out 8 (ish) Th/s on the two remaining boards.

I'll let you know how it goes...
