Conductor: 18 AWG i need 16 or less |

i get my 2 antminer s9 batch 12 today i powered one by EVGA 1600G2 in cold room using air condition and the second still not powered because i can't find C13 cord for AWP5  |
|
|
|
|
i need cee 7/7 schuko - c13 16amp on amazon
i can't find one!
|

i have this cables come with computer C13 10A-230V (0.75mm)
why there power supply using C13 in first place ?
they should use C19 to find cord with 2mm
now i need to power 4 boards on 2 antminer S9 using one power supply on 220V
can this power cord handle that ?

i replaced my air condition to a powerful one 2.25HP now i increased freq from 500 to 550 and free my fan from 100% speed to auto  |
|
|
|
|
what i hope to see in the future is Freq/Temp tasks
like what a fan do to manage temp i hope to see freq did also
so i can add tasks like ( if temp exceed 95 reduce freq to 550 ) ( if temp lower than 90 increase freq to 575 ) and so on.

Hello.My hashboard arrived at Bitmain service, UPS says it was collected and signed by MR SUNG yesterday, 09.09.2016,
but on BITMAIN service ticket it is not updated as collected.Should I worry ?
I sent a mail to bitmain support regarding this
It takes sometimes up to a week for them to update it. they update my ticket after a week with this  and send it to me is that mean it repaired or replaced or what ? they don't tell me anything They generally will ship it back to you withing a few days, once they post that status on your account. they shipped it to me is than mean it fixed ? |

is there away to get alert on mobile and computer when antminer get high temp ?

Hi all,
I would like to send my faulty hashboards to Bitmain. As I understood I can remove hashboards and than I'm creating repair ticket, RMA etc.
Or do I need to inform Bitmain before I remove the boards ? (which would be very stupid practice) but I would like to make sure I do everything properly.
Thank you
open a support ticket first and do what they ask you to do http://support.bitmain.com/hc/en-us/ |

now i get no lower than 0.0023% Ja that is more than you were originally seeing and is puzzlement why, but -- still perfectly acceptable and I'd say is fine. My s9's range from 0.0002% up to around 0.003% after a few days/weeks of running. 3 of them are running stock speed, 4 are slightly under clocked to keep chip temps below 100C. Start pushing 0.005 and then I'd start poking around. that what happen to my board today i replaced the place for both boards and decreased freq to 500 now every things is ok so i think if we kept our miner's chips in temp lower than 92 C from the first day we will keep it from this drop that happen to it after some weeks and make it get more HW errors than it get in its first use  |

here is picture from 3 days before what happen to the middle board ( on 550 Freq) after 3 days and half i get 0.0001% Hw errors now i get no lower than 0.0023%  i think i can't restore this board to the old situation i tried restart or close the miners for hours still have same HW error |

Are you hashing with 2 hash PCB in the case instead of all 3? i get message today that my board repaired and sent to me, but ..
yesterday i get my miner stopped and after restarting i found one board from the both still i have get temp higher then the other by 10C
and getting many HW errors 0.0023%
from 2 days the highest HW i get is 0.0003
i down clocked my miner from 550 to 529 ( its B9-600 Freq)
now one board have 87C and the other have 97C
can i under clock one board only ?
yes, in a room with air condition and down rated from 600 to 529 is that wrong ? exactly what happen after removing third board so i decreased frequency a lot to make its temp in acceptable range but after a week i suddenly get 10X more HW than what i get from it in the past  I believe he is pointing out that if the missing board is not the middle (in other words one of the side boards) then the air flow in the cabinet would very likely account for one board running a lot hotter than the other. One board would have lots of space on one side of it for air flow and heat dissipation (the center board) and the other would not (because it has the center board close on one side and the cabinet close on the other). So the air flow differences from the missing board could account for the heat difference. |

Hi guys, I've been trying to read up on overclocking my S9s, now before you roll your eyes at my post, I understand the waranty implications and I am certain it will run hotter. My question is, is anybody doing it? If not, what are the risks/disadvantages? Also, why is Bitmain bringing out a 11,85 that runs at 550MHz, a 12.93 running at 600MHz the 14.0 running at 650Mhz. Surely this can't be the same machine running at different frequencies? I'm trying to understand this concept but there really not much to read up on, on google  wait until your first 3 months gone and start to overclock because there S9 boards have many hardware issue so leave it under test for 3 months first i have special environment each miner have chimney to Take out the hot air to the outside and have a strong air condition to cool the room and i will wait until warranty finished to overclock with temp less than 90C |
