Very sorry to hear about the DOA S9, fortunately, i haven't had any bad luck on the S9-B12 that i received today. Hope it gets resolved quickly...

it is 2/3 working so i am down say 450 usd unless they replace it.

as for lost password it is pointed at my pool

At the risk of getting even more OT...

I guess you're not using a proxy? If you were, then this would be less painful because you'd still be able to change the pool at the proxy level.

I've been using the Stratehm stratum-proxy on an RPi and am happy with it. Pointed my S9s at the proxy on a local IP and now I can manage them as a group.

That said, I'm sure there must be a way to reset these newer models. Probably have to write them an email (they never answer support in  my experience).

Hmm, can't say I've tried it on the s9 but doesn't SSH use a different user/password than the GUI? I think with the s7 it is admin/admin (could well be wrong there). If SSH lets you in then it's a matter of will Bitmain's OS let you change & save the GUI access words.

edit: Correction, M's Miner Monitor says SSH words for the s5 are root/root and I believe those worked on the s7's.

Hmm.. Looking at the s9 pic shown in the manual I see a BB in it. Does the batch 10 have a BeagleBone? My batch 11 don't. That said, bet that once again Bitmain may have f***ked up the reset like they did on the s3(?)...

Well like I said at least it has a pool setting that works.

Maybe you need to sacrifice some of the critters from those cages in the barn (rabbits?) to whatever gods of BTC you seem to have ticked off...

Seems like I should do that  well at least it is mining on my pool of choice.

Even If I can't reset it. Grin

this link may not work but I followed it and setting stay set

Ja, possibly the board failed QC a xx speed so maybe was binned as runnable at a lower speed.

I'm rather puzzled by the top heatsinks not being nicely (or at least better) aligned. Probably explains why some s7/9's are sirens and others not too bad.

You would think that they would be using a pick-and-place to put them on which should be very very repeatable or if being put on by hand (shudder) at least a frame of some sort to locate them and keep in place until the thermal epoxy hardens...

yeah they could be straighter.

Okay a completely   different problem.  this 2 board miner is working fine but I fucked up the user name and or the password.

So it is mining away on kano.is but I can not longer access it.

I was trying to change the user name from root to a different user name.  and I was trying to change the password.

A  long day and my  mind is very stupid at the moment. Grin

So I now do not know:
 the  user name
 I do not know the password

and the little reset button does not seem to reset the miner.

a little help to reset would be nice.

Anyone here read Chinese? If so, are those hand written symbols on Phil's bad board readable?

In particular it would be interesting to know the meaning of the symbol that looks like a 4 with a line through it.

i think it means they need to send phill a new board free of charge.. the upside 4 means power.. so im guessing it says no power.. but i dont speak chinese.

I have been contacted by Yoshi of Bitmain warranty.  

I will need to pull board take photos and send to Colorado. Better then spending 110-149 to ship to China.

   I will drive to the solar array on monday and pull boards.  I will continue to post how it is handled.  Include Emails with redacted info I.E. my personal info.  I go back to older times in BTC  when BFL  and real asic ripoffs were all over the place. So I actually want Bitmaintech to figure a better warranty method.  Including the idea I posted above.  I.E.  a discount for no warranty  Since shipping a piece of gear and spending 110-150 to be told no warranty is bad for business.


I salute you for your efforts and I get it that you want it to be better for everyone.
Hopefully, it would not be a one-off deal, but something that will change their understanding of the situation.
People cannot continue to buy miners that brake even in a year while warranty is so inadequate.
That said, no warranty at all is just a recipe for potential abuse. They need to make it 1 year.


Yeah maybe 6 months and maybe a better method then shipping to China and getting rejected.

Here are 2 photos of the dead board. Some things to note it looks to have zero damage.
 It has hand written notes on one side.
The good boards in that miner have no writing. My guess is this board had a fail on its quality check at the factory and then a tired or careless worker installed it.
I worked in assembly line work to help pay for my college degree.  This error happens more then one would think.
I am pretty sure I will get a replacement board Which reminds me I will need to give Yoshi a return address.





notice good board has no writing here

... DC does not travel well over distance ...



Yes, it is.

We are talking about residential 240V AC power & not 500KV of power transfer.

Anyway, it's got boring now....... Roll Eyes




 DC actually travels BETTER over distance, due to AC suffering from skin effect.

 The REASON AC is more common is that it's a much lower technology need to change the VOLTAGE of AC power, and HIGHER VOLTAGE is a much more important consideration on losses for power transmission than skin effect is.



 Bills are generally in wattHOURS, not watts straight up - though some electric companies charge a "use fee" on some of their rates based on the peak watt usage IN ADDITION TO the actual charge for watthours.



 The problem with common lead-acid batteries is that while they might have a "nominal" voltage rating of 2Vdc per cell, they ACTUALLY have a normal voltage a fair bit more than that. A common auto "12V" battery usually has more like 13.5ish volts output at low amperage draw when full charged, and charging circuits commonly go as high as 15VDC.
 "12V" Gel Cells like many UPS units and some solar setups use tend to be in the same range as they use the same technology with some minor modifications to allow them to be sealed.

I was also thinking about awesome lasers a bit, but I only know the classroom math there instead of actually playing with them on a daily basis; be assured I am darn jealous.

One KWh is 3.6 megajoules, right?
Ja. 1000 watts x 60 sec x60 min

At the risk of seeming unnecessarily pendantic, but for the sake of correctness:

Now comes where the confusions seems to be: The amount of WORK the volts and amps together produce. The unit for that is Watts or Joules and has a simple formula. Watts = Volts x Amps and the rate of use is Watts/time

Everywhere except apparently India the electric bill of all consumers be they residential or industrial is based on Watts  - from an AC source - consumed.

Watts are the amount of work; Joules are energy. Work is energy per unit time. The electric bill is actually based on energy; you are billed in accumulated kilowatt-hours (equivalent to 1 kilowatt draw [at 240VAC, about 4.17A] for one hour), which since watt = (joules / time), watt-hours = watts * time = (joules / time) * time = joules. I'm not entirely sure what to make of "the rate of use is Watts/time".

1300W in hour

24 hours x 1,3 kw =31,2 kW/h

24 hours * 1.3KW = 31.2KWh -> there is no unit division, but unit multiplication. The proper unit is kilowatt-hours, not kilowatts per hour.
Absolutely correct.
I probably should not have included Joules in the discussions because as you said, Joules are the amount of energy independent of time and it's relation to Watts is Watt-seconds eg 1 Joule = 1 watt for 1 second. Play with watts over time and Joules stay the same as in 10watts for 0.1sec still = 1 Joule.

What is fun on my end is how that equation plugs into ultra-fast lasers: eg a 1pico-sec pulse delivering 85uJ translates to a peak power of 85MW. Things get rather weird when hit with power like that... Wink

The "the rate of use is Watts/time" was applying Watts to to Watt-hours and should have been Watts x Time
