didn't really save any kernel logs but this is what i sent to bitmain for the repair request for the first miner.


as for now it shows the following


so i would assume the J8 is possibly board no3 out of 3 s9s boards was the missing one.



for the second miner " image in OP it was J7 missing.

but from what i recall they both showed the same info of [Jx] has 0 asic

so 1 of my S9's suddenly stopped showing one of the hashing boards.



i searched online, contacted Bitmain , did a dozen of re-setting , firmware changes and tens of rebooting attempts but nothing worked.

so Bitmain asked me to send the miner back, and the best settlement was me sending the BAD hashing board, yet even with that offer it didn't make sense to me as the shipping cost from my country to china is kind of expensive and i just thought it was not worth it. so i was about to give up on that hashing board until something strange happened !

I for some reason flushed the autofreq firmware and suddenly the missing hash board showed up.

this is the name of the firmware > Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz  

can be found on bitmain website > https://service.bitmain.com/support/download?product=Antminer%20S9

now before you say it might be just my luck. i flushed back another firmware and boom ! hash board goes missing again !

still until that point i thought maybe only this particular miner that has this fix work for ! so i searched for a used S9 with a board not showing "bought it for pretty cheap" i tried the firmware and damn ! it worked again .

I do not have any TECHNICAL or even REASONABLE explanation for this !

I just wanted to share this with you all , maybe someone find it useful.

I deleted my negative review on his wall because he paid back the money he owe me.. but i am keeping this topic unless the mods think it should be deleted. i think it's for everybody's best interest to keep this topic because i am pretty sure some people won't delete their negative trust on stingers trust page ,and they use this topic as a reference, so others need to see it, read it and then judge for themselves whether or not they should trade with stingers.

i will also edit the OP and mention that stingers did pay back my money but i will leave the initial  "story" so that people can learn from my mistake to never ever trust someone just for their merit or rank.

Ok so just to clarify things to everyone here. I would like to report that "stingers" paid back the money "150$" that i sent to him. he texted me on telegram as well as on this forum explaining to me that had his own reasons and asked for my forgiveness.

now regardless of  his intentions or story of why he stopped replying. I do appreciate that he finally came and talked to me and of course paid my money back.

so from my side the problem has been solved and i do forgive him for what happened. i will also delete my negative feedback on his trust page.

 but again this is a lesson learned , never deal with anybody without escrow.

thanks to everybody for supporting my case and thanks for keeping this forum as safe as possible.


Mikey.

what did you expect then ? the Equihash network is relatively small and mainly run by nvidia gpus. 1 z9 mini over-clocked z9 mini = 12 * gtx 1080ti ! 190% in 90 days change is nothing. now that they sell for cheaper, you should expect something like 1900% pretty soon. those z9 minis will do MAX 1-2  $ daily at most in 2 months at most ! . mark my words come back in NOV.

** so this is what bitmain has on thier page https://shop.bitmain.com/product/detail?pid=000201809111803105065Lb6UvUc068A

APW3++


APW7



so if you are using 110 vs then you should get the APW3++ which give you 1200w . if you are using 220v then you should get APW7 as it gives you 1800w instead of 1600w.

you don't have to push your PSU to the limit if you don't have to . also you do not want a lot of spare power sitting there doing nothing when you have to buy another psu ! . if there is a room on your psu which you can use then just use it.

I don't have a 120v circuit i think only people in the U.S and a few other countries have that old power infrastructure. i don't know how much exactly in WATS you would be able to pull from APW psu but i am sure it is not 1600w. i think 1200w is the BEST you could wish for but then dyor regarding that matter.

assuming you can get a 1200w of it, then it's safe to say that you can consume 1200w from it , all year long .



 

this is completely based on your own or someone else's speculations and it has no solid proof what so ever, the max you see on the label is the safe point which a good psu should handle all day long. I have been pulling about 970w of  a 1000w psus on my rigs for years and zero problems, it all comes down to the room ventilation and the quality of your PSU. bitmain psu is a solid psu. i have some A3 and S9s slightly over clocked consuming close to 1500 for ages and never a problem with the PSU. you can test it out yourself if you like. 

it's the other way around. it is dangerous to connect multiple PSUs to a single ASIC.  you can connect as many asics you want to a PSU as long as both your PSU and the 6pin connected can handle the power needed. from a theoretical point of view you can have 4 z9 minis connected to 1 APW 1600w psu ( each z9 mini takes about 350w if not overclocked" ). how ever i would not do that until i verify that the 6 pin connectors which are going to be split can actually handle the load.

Seems like you guys can't keep up with bitmain and the other major Asic manufacturer. with all due  respect !  X11 coins are nothing but bullshit !. the only coin there is that MAY be worth mining is DASH , the rest are worthless shitcoins with market cap bellow 20 millions $ .
! also the fact of risking 15,500$ + shipping and other expenses in a single machine is not the best thing I would do.

 I rather get 4-5 Z9s with this amount of money and make 2-3 the profit ! anybody can do the math ! sorry but this is so disappointing.!

I used to be a big fan! but i gotta be honest, after all this time i was hopping you guys would come up with something that actually worth investing in.
I hope that you take ROI / PROFIT as well as other options available in the market for your next one !

anyway, Good luck

Still HODLING 

nice app , i like it. only if i could all the miners i have together

Bump

just a yearly bump.

exactly my friend !  . the first and only RED he had was some drama bullshit! . that's why i didn't really care about it ! . now the new REDs he got is SCAM-BASED. so it has more meaning

Daily Bump

Dude got his wall painted in red and that's the point of the scam accusation forum. thanks to everyone who helped in the painting process  , i hope that he's now a more OBVIOUS scammer.

Exactly the way i was thinking before sending him the $$$ . i mean with such an account rank and a little bit of brain and work you can make some good money !! .  look at all these Digital goods , the least you can do is to act like a middle men between too newbies ! make some profit . because by default NEWBIES " like myself" . trust those  "Legendary" members based on the exact point you stated ! . it's common sense and simple human nature ! but it's all wrong in this forum ! .  i have dealt with bunch of newbies and some were legit and professional ! . so this Rank shit is meaningless to say the least !. my brother was scammed by a localbitcoin paypal seller who has well over 5000+ reviews and over 1000 btc trades ! . guess for how much ? 500$ ! dude charged back and ran away ! . it was probably a big hit for him that made him run away " not the 500$" probably another HUGE hit that worth a couple years of working " my brother was just unlucky to be among those poor people who had pending transactions with that guy while he was planing for the big hit.  many people will act and be legit for a while for a BIGGER and LARGER scam-plan ! . you will be amazed when you see the numbers of previously-legit members including former escrow agents on this forum turned into scammers when they had the chance !. 

Money drives people crazy ! anybody may turn into a cold blooded scammer at any second specially when they can easily get away with it ! moral of story " as long as you on the internet the chances of getting scammed is relatively HIGH.

dude , i bought well over 3000 bitmain coupons on the forum " many members here can confirm" that's well over 250k USD "aka quarter a million " , i got scammed a few times for more money than this, on the other hand i met a lot of legit people. i wasn't greedy as you may think , i was foolish to think that a legendary status means something when it clearly doesn't . because i had dealth some a legendary members with no escrow and things were smooth !
 as for your point of  " You should never deal with anyone who has negative trust"    i have to disagree to this because many negative reviews are based on "personal bullshit and drama" that's why you can always reference your reviews to support your case, a lot of legit people here have their walls painted in red because of so many reasons , for an instance once somebody accuses someone else for being a scammer chances are the person accused will post the same shit on accuser trust page and then at least one of those reviews will be irrelevant if not both . i am not sure if you getting my point !

anyhow, thanks for the reply.
