Title: s9 Post by: samosamo on March 16, 2018, 12:10:59 PM Hello,
I have 60 pcs S9 miners. Some times some S9 have error with HB "xxxxx" , and ussaly send to reparier to china. Two weeks ago i have same problem with one of miner. But befor i have send to china, i put on other miner ( who work normaly) this 3 HB and was suprise that now all 3 HB work. So i put gain back on error minet this 3 HB and again show all "xxxxx". So i figured out that problem was not with HB . So on stock i have 2 controal board new one and i put on this error miners and miners not work not because " xxxx" but because too low tempreture of chips. So i change 2-3 difrent firmaware and same problem. Now i asking if anyboday could tell me to solve this problem. Because my HB are ok, but on this miners not runing with old controal borad ( because "xxxx") and also new controal board ( because low temperature) . I dont want send back complete miners to chine, because they need 3-4 months to send back to me. best regards P.S. : I apoligized for my bad english :) Title: Re: s9 Post by: SGMPhil on March 16, 2018, 06:15:24 PM You might want to purchase a couple of spare controller boards - they are not expensive.

He stated he had a spare controller and tried that, but the problem returned... Samosamo - did you move controller cables with the controller, or did you use the ones with both test? Did you use the same power supply each time? Title: Re: s9 Post by: pantalyra on March 17, 2018, 09:56:22 AM I have a fairly good sized farm here. I had everything wired up properly on my end for all my miners and was having a similar problem with a new batch I ordered. Was bashing my head against the wall for over a month going back and fourth with parts and RMA. When i got them back I had the same problem as before...
Long story short, it turned out I was just crossing the threshold of what the cities powerline/transformer could provide. It might be worth looking into. |
