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

How much are daily mining Pura  coin with D3 miner?

I have 7 D3 on D3pool form Saturday 14:00 . Til now they make me 0.022 BTC that means , 0.0044 BTC per day , so one miner daily 0,00063 BTC wich are cca 5 €/day.

It is not this a litle to less, because we talk about 8-9€ per day?

I have put 7 D3 on pool, isn't it better to set difficulty at 96 instead of 64 for the D3's though?
