So go back to 500 freq and 80%  and run for days.
I know there is a slight language barrier. 

So let me be very specific when you ran at freq 500 and fan 80%  what happened after 30 minutes?
Did you turn it off and then test at freq 550 and fan 80%?
Or did it fail and turn itself off?

   If it worked the entire 30 minutes and you turned it off please go back set it at freq 500 and fan 80%  leave it there for at least a day.  If it works for a day straight at freq 500 and fan 80%  we will have a better idea of what is wrong.

Yes i tried at 500 freq and at 80 % fan it worked well for 30 min now i done 550 freq and at 80 % fan
and fan should be kept automatically or manually ,if manually then at how much % ?

dang still so many having issues with s9's....the 4 i ordered have had no issues. i thought one had 2 boards die and i freaked out all the way to the server room i run them in and found out the breaker got tripped on one of my 230v apc 5000w converters causing one of my power supplies to go off on 2 of my miners (1 psu each) so the hash rate dropped by 2/3 but after turning them off and resetting the internal breaker for that set of plugs everything fired up and works just fine. the key is keeping those temps down and running them in a non humid area or in a tiny room like i have seen others do. its getting cool outside though so running them in a shed or a garage wont be a good idea EVER but it wont be as bad as running them out in the garage or shed in the summertime like others have done. i just cant bring myself to abuse $5k worth of miners like that. when a new batch goes up i will be getting the rest of the miners needed to replace all of my s7's so some can come home and be my space heaters at lower freqs and the rest i will sell locally or online.

+1 or +2 as i seems to be.

I had an early S7 where one of the grooves in the chassis where the boards slide in were not fabricated correctly.
The one board which was forced in that "slot" had been shaved so it would barely fit. During assembly, QC, etc someone had slid / forced that single board in the chassis enough the board had scrape marks and literally removed part of the board. There are pics in a thread around here somewhere. It caused the board to have an unusual amount pf mechanical stress and the board was warped when installed.
When that board was connected it developed similar symptoms o what I see in your videos. The other two boards ran fine.
Bitmain in Colorado *Actually Yoshi is who I worked with while making arrangements* - Yoshi took care of the issue and me during that scenario. It wasn't fast, but overall he did make sure I made up for time lost.

My most recent S9 failure is unfortunately not covered by warranty. I had a symptom before the warranty expired but I failed to report it. I had one board with an X. I have read many posts by people who were told one X did not mean it would be covered. Within two weeks the board was dead and I was approximately two weeks out of warranty.

I tested this recent failure by first not having any hashboards connected. Fans ran and everything looked good. I installed the board I thought was the problem but it ran correctly. I disconnected it and connected the next one. This one showed the same symptom which by then was Xs across the entire line.
I exchanged the cable going between the controller and hash board with a different one which was functioning - no change.
I tried a different control board port which was functioning correctly.
I tried different cables from a different power supply.

I am confident the issue is the hash board.

Two things which should be available I have not located:
1. A board drawing covering basic test points so we can isolate to a particular component or at least a specific circuit.
2. Where is the S9 firmware? I must have missed a post stating what is going on with firmware. I would like to have the ability to re-flash as an option.
Anyone - Please let me know where this is located.Hopefully I m just being dense and i is right on the bitmain downloads page.

@sunny163
Take your time
Make notes of everything. Mark your hashboards, cables, etc
Be meticulous and consistent
If it is under warranty do not break the warranty seal until you receive permission from Bitmain support and try to get everything in writing. The Colorado people have done good things for me, but they are not good about returning calls or getting things addressed in a timely manner.

If there is physical damage to the board immediately take pictures and get those emailed to support while pressing for a response. There is not a good reason to waste more money for shipping if they are going to deny your claim anyway.
Make this clear and again get it in writing.

Then evaluate options.
I do not see any physical damage to my latest S9 board failure. I am sending it to Colorado and I understand they are unable to give me a price until they evaluate the failure.

Take your time. Do not make rushed decisions and again document dates - times - names - instructions - EVERYthing

Good Luck

Has anyone had a hashboard repaired out of warranty?
If so would you mind sharing what you paid and if it was done in China or Colorado?
Feel free to PM if you feel more comfortable.


I am shipping an S9 board, but please specify if your experience is with an S7.

Much appreciated

I think you should try it at lower freq  and not max hashrate.  Since  you are altering your info  a lot and I don't know what freq you are at or what fanspeed ?

did you do freq 500 at fan 80%?

Can you video tape how the LED and network port LED flashes?

Also done the usual, swopped the PSU's about and given it a brand new APW3+ (the new ones) as I have had 3 of the older style ones fail so I was kinda hoping it was the PSU

hi again all,

still having issues with this S9, I have rebooted it about 6 times now, it keeps restoring to factory defaults then just disappears from the network???

then when you reboot it, its network lights, light up briefly (and the coinciding ones on the switch) then go out after 1-2 seconds, it cycles this over and over, on and off with both the "fault" and "Normal" LEDs dimly lit,

It also doesn't respond to having its reset button held in for 10 seconds,

Any advice or should I just contact bitmain again

That's what I was thinking too, why I was recommending he test using only one board at a time.

Honestly it sounds to me like it could also be a PSU overheat issue.  Usually if something works fine for a period of time and then stops I think overheat.  Do you have another PSU to try? 

I have 2 mbps and no one is using to download anything so speed is not used

Do you think phillip PSU or controller board will be failed because 10-15 min it is running perfect with good temp and max hashrate

you could be correct  as I have really good internet 50 down 15 up  and very solid do  not drop connections.

I tend to forget  that many people have bad or unstable net connections.  I have read poor internet is common in India

For example
here is a ranking for India as number 5 for bad service

http://www.elist10.com/worlds-top-10-countries-slow-internet-connection/

India is around .25 speed vs my speed of 50/15  so I am 200x faster on download and 60x fast on upload

here is the fast list

http://www.elist10.com/worlds-top-10-countries-with-fast-internet-connection/

so if the poster sunny163  is under 1megabyte speed and more traffic is on his service or the service sees his 24/7 online with the miner it could be simple throttling by his net provider.

this happen to me before and i found the reason is internet cable after more than 2 hours of restart and try
happen again after a month from that and found the reason is my sister using torrent to download something and get all internet speed to her
check your internet and try another pool too

well  it could be  the fans are damaged not the controller.  and once again it really is not your fault since they do not say anywhere don't set the fans on manual speed of 100%

But there is no question that you need to replace

1) the fans and the controller----- worse case
2) the controller
3) the fans------------------------- best case

try a simple test set freq to 500 fans to 80%

see if it runs longer  like for hours and hours.

 if it keeps running at 80% fans and freq of 500 .

 you could stay at that point or you could order rma on fans and controller.

my guess is lower freq and lower fans won't help.
my guess is you only need the controller.

of course you will need contact bitmaintech in china vs bitmainwarranty in usa.

my opinion is they should have warned about 100% manual fan speed setting. they did not.

i warned about 100% manual fan speed settings but I am just a miner.

the machine is running for 10-15 minutes sometime 30-40 minutes with perfect hashrate and perfect temp and then suddenly it stops and starts within second and then the machine is not able to mine it is running miner fan is running at faster speed then slower speed again the same and not mining 

I am in India

I posted this months ago.  I said running fans at 100 % for months is not advisable.  I said it would burn out fans and or controllers.  I said it was common sense to set at 90 or 95 %.
Here is another piece of info. The manual does not tell you this. So it is the manual and bitmaintech that should mention this  . My advise months ago was my advice no one else placed it but the fact is 100% fan setting is wrong on this gear.  Since I killed a controller at 95% it could be a setting of 85% is better then my setting of 90% 95%.

I will also mention the s9 is more delicate then the s7 or s5.

My annoyance should be made clear do not set the fans at 100 percent. Is my advice and no one else's
I just get annoyed when people do not practice common sense.
In the case of fan settings bitmaintech should say a manual setting for your fan of 100 % is not advisable
They don't say it.
They do say overclock of freq voids warranty.
I know of nothing anywhere that says setting fans at 100% will void warranty.

I told him just buy one from bitmainwarranty. Since shipping it to China and waiting for it to be returned costs more then just buying one from bitmainwarranty in Colorado.

This is just getting ridiculous Phil and you Freaking know it.>   I wish people would stop making excuses for this company and giving them ways to get out of shit.

Can Phil or god forbid Bitmainwarranty give the list of what not todo.   Here people are replacing controllers left and fucking right and now it finally comes out that they arent meant to run at full fan speed?  What about letting the software control it where it would pulse up and down thus causing spikes in amperage as it comes from factory.  KNowing that the controller is made to fail(why would i think otherwise its planned obsolescence ffs), This S9 is the biggest POS fail ive seen .  And the countless excuses being made for this company just grinds my gears.  makes we wonder why i didnt get that gig.  Must pay rather well.

you definitely damaged the controller by running fans at 100%  .  order a new one  from bitmainwarranty if you are in the usa.  the cost will be about 118 + shipping.


I will repeat this in huge letters

Never set fans to 100%  do 90%
