Your issue is stated in the kernel log


Each of these chains J6,J7 and J8 must have 63 Asics each, what the kernel log is saying is that all 3 hash boards are dead, in other words, you bought a dead miner and you should contact the seller and ask for a refund.

The other possibility would be a dead PSU, which you should also ask for a refund for, you should also check all the 6 pins cables and the ribbon cables, make sure they are tight.

If you have the tools, then follow this video https://www.youtube.com/watch?v=5WH7g61d90w , the voltage and resistance of RI,BO, CLKO, and etc values might be different on the S9k, but usually, every row of chips is considered a domain which should give you the same readings with small variance, on the S9 the top row and bottom row read higher values than the middle rows, if you need more info regarding this do let me know I'll see what I can collect.

The video shows a fixture tool that you don't really need now (not worth it just to fix a broken S9k board) so just test all the chips manually one by one, start with 49,50,51, and then the row which contains them, usually the bad chip/s will be around that area, it's also common for chip no.0 to go missing, and then finally test all of them.

Keep in mind that to test the voltage the miner needs to be sending signals to the chips, which only happens for a few seconds before it stops, you can however test the resistance offline (no need to be plugged in) and then confirm the voltage, you have a few seconds from the time you turn it on until it stops, if you have the time, just power off and on as many times as you need to get all the readings, you save over a $100 on the fixture tool by doing so.

First of all, I should say thank you for posting such a detailed and neat question, unlike 99% of the new members here who don't do basic troubleshooting before posting, heck they don't even post any details and expect us to tell them what's going on with their mining gear.

So your problem is


S9k has 60 Asics on each chain/hash board, the signal here was interpreted at the 50th chip, which suggests that either chip 49 or 50 has a problem, the problem could be a loose heatsink or a dead chip.

You have bought the worst mining gear bitmain has ever made, oh, not just bitmain, the worst anybody can make, it's bad enough that nobody can make a gear that is bad as it is, you follow the logic?

I have written a complete topic about, its title is WANRNING! Do Not Buy Antminer S9k, the failure rate for these gears is well above 70%, so please - be prepared.

Now back to your problem, you need to physically inspect the hashboard, apply some pressure on the heatsinks to see which ones fall, and then update the thread.

Well I would argue it's the opposite, simply because the earlier we are in the epoch the sensitive the change is, 10% has more likely to fall than to go up, this is where the expected lower value of 2.5% comes from, but anyway, we are still very, very early, let's wait for a couple of days before judging this epoch, we know this month will be the first month of s19 series and some M30/31 gears, but it's still the 11th, not sure if some batches are delivered and going online, I'll check with some of the folks who are expecting gears this month to see where things stand.

معظم الدول العربية لديها نفس المشاكل, اعتقد اكثر منصة مرونة في هده المواضيع هي Binance, اما بخلاف ذلك فسيكون عليك الشراء من خارج المنصات من مواقع مثل paxful او localbitcoins, الخيار الاخر هوا الاستعانة بأحد الاشخاص الموثوقين هنا وعمل حوالة Money gram / WU او Paypal او اي طريقة تتفقون عليها, طبعا يجب الحذر من النصابين وحاول استعمال وسيط موثوق.

الخيار الاخير وهوا واضح ولكن قد يكون قد فاتك هوا البحث في قروبات الفيسبوك وتليقرام عن اشخاص مهتمين بالكريبتو في مكان اقامتك وبدون شك سوف تجد ناس تبيع وتشتري باستعمال الكاش, وهده الطريقة الاكثر شيوعا في معظم البلدان العربية.

I live in a country with a very hot climate, and even when temps are pretty high, I can get away with 50% fan speed on S9 which uses two 12cm fans, and 50% speed is 2500-3000rpm, provided that I underclock the miner to 10th or so, where power consumption is below or right about 1000w, 140 watts worth of heat is really nothing serious, it can be really silent and run in a hot climate.

@sidehack, sadly, I am not a hobby miner and thus I won't be interested in small mining pods, although I think 2terahash per second at 140w is a great achievement, and I have always admired your work.

With that being said, if the price is right, I might be interested in 1 or 2 of them just to solo mine on ckpool.

Good luck.

ماشاء الله اخي حظك "يفلق الصخر" في الواقع الهاش الذي وجدته انت يتطلب 1,048,576 محاولة وبناء على سرعتك التي تم حسابها في منشورك السابق كانت 1.4 محاولة في الثانية يعني تحتاج الى اكثر من 8 ايام لحل لايجاد بلوك يبدا ب 22222, وكنت اخطط لان ازود الصعوبة في البلوك القادم واضاعف الجائزة.

اما بنسبة لقبول البلوك فكل تأكيد هوا مقبول لان الهاش الذي وجهته اصعب حتى المطلوب وفي التعدين الحقيقي مطلوب منك تجد بلوك يساوي الصعوبة المطلوبة او اصعب منه.

النتيجة الحالية:

Khalid = 7
1+icy3 = 1
yhiaali= 1
ulven = 8

ارجو من احدكم مساعدتي في التأكد من النتيجة.

And what happens next when (if)BTC tanks? they will be paying more BTC, or they will have to re-evaluate the situation every time a major change in price happens which isn't very practical. There is really no easy "fix", you pay in fiat - you are subject to pay more BTC, you pay in BTC - you become subject to pay more fiat, which why I think most businesses will pay in the "currency" they earn in order to keep their budget in place since Chipmixer is one of the few companies on planet earth that earn and spend only in BTC it will be hard to peg the payment to fiat, on the other hand, fiat wise while BTC price is at levels is a lot, and Chipmixer can really save a lot by reducing the payments at least temporary, and as Suchmoon said, most likely nobody will complain.

With that being said, and given how successful Chipmixer is and also how long they have been in the business, I bet they are more capable than most of us in making decisions related to advertising campaign budget.

It trades on the 1H chart for the most part, but the take profit points are very extended, and it uses a trailing stop so some trades do extend to well over 100%, but since my main focus is not to lose money so the initial SL kind of tight, so the bot can make 10 losing trades of small loses and then makes 1-2 large winning trades.



I could never develop something that works on 1M or 5M time frames, even when the backtesting shows great results, the real testing shows other wise, given the nature of the crypto market I just don't think I can do with these small timeframes, but this doesn't mean I don't need the bot when trying to trade 10 pairs on the 1H chart, it still requires hours of monitoring and the worst thing is the entry and exit, it's very hard to be available once you need to exit.



If you look at the last couple of close positions, in my manual trading I only entered one EOS/USDT trade which resulted in a loss, the bot managed to get all of these trades on these two pairs, and despite losing 8 out of 12 trades, it still made 60.48% profit against 8.02% loss.

But I wouldn't get excited yet, this is a bull market era, most random strategies will work and outperform manual trading as long as they only open longs, the real challenge is the side-ways and bear markets.

On the specification sheet, it says "Number of Immersion Cooled Units = 90" which means it's a complete package (rack) which you would buy empty and then fill it as you want,  so each unit will be 50th and you can have a total of 50th*90 units or 4.5ph.

The specs are messy and hard to understand, it says each unit is 50th and consumes 3400w, and then it also mentions that the max hashrate for the whole unit can be as high as 7200Th/s and if you divide that by 90 you get 80TH per unit, and then it also says the max power consumption is 306KW, which brings me to think that there are units which are as efficient as 42.5w/TH (based on 306KW*1000/7200th).

Is it just me or these units are outdated and far from efficient given that the AntRack takes S19 pro hash boards which can do 29th/w (on stock settings) so with 306KW you are getting at 10.5ph instead of 7.2ph, there is of course a good portion of power consumption for cooling, but still.

I don't like to be bearish, I "hope for the best and expect the worst" I also learned to lower my expectations with the things I have no control over, I am heavily invested in bitcoin with both money and time, it's for my best interest that bitcoin goes to 1M or even 10M before I leave this world, but I don't see that happening simply because I believe bitcoin follows logarithmic growth rather than an exponential one, and this makes me think that 1M bitcoin will need at least 10-15 full cycles, that adds up to about 50 years, I don't know how old you are, but I certainly won't live for another 50 years.

What were you expecting? with 8ph for 24 hours (which you didn't even get fully) your chances were 1 in 140, it would be surprising if you hit a block but very normal and expected if you didn't, after all, you were going in for about 10% of the block reward which is about $27,000, sadly, it didn't work out.

اعتقد ان هدف المسابقة قد تم تحقيقه, وحتى النقاشات والمعلومات التي جائت في التعليقات لم يكن مخطط لها بل اغلبها ارتجالية, هدف المسابقة بالدرجة الاولى هوا فهم ماهو ال hashing وكيف يكون حل بلوكات البتكوين, بالرغم من بساطة هدا الشي الا ان الكثير لايفهمه لذلك اعتقد الان وبعد الممارسة العملية التي تحاكي واقع التعدين, يمكن ان نقول ان من شارك في المسابقة او حتى من يقرا التعليقات سوف يفهم بطريقة مختصرة كيف يتم التعدين, اما الجانب المادي فهو مجرد تحفيز للتجربة العملية, فهدا الشي مهما فهمته لن تتمكن من اثقان تفاصيله الا بالتجربة, فعامل الحظ وعدد المحاولات والعشوائية كلها مختطلة في ان واحد ليس من السهل شرحها نظريا فقط.

لذلك مبئديا ربما نستمر لهدا البلوك وبعده بعدد بسيط من البلوكات نقوم بأنهاء هده المسابقة, سوف افكر اكثر في الامر بينما نسمع اراء الاعضاء الاخرين, مشكور اخي خالد لتفاعلك.

use the code function when you paste the kernel log, you are going to get into troubles, the mods here don't play around.

the kernel log should be like this


The good news is that all 3 chains show 63 Asics, so a total of 189 chips which is exactly what a perfectly functioning S9 should show, the kernel log you posted last isn't complete and thus I can't say for sure what's wrong with the miner, but if I had to guess, it would be a pool connectivity issue. If you are serious about getting help to fix your miner you SHOULD

1- Post the complete kernel log in a code format
2- A screenshot of the miner status page
3- A screenshot of the pool settings (you can hide a portion of the worker if you need)

Use one of thees two websites to upload the image and paste the link here

If you don't provide all these details you simply won't get the proper answer, so it's your call.

حسننا اذا لنبداء في محاولة حل البلوك القادم وهوا البلوك رقم 11.


ستكون الصعوبة هده المرة 2222 يعني بداية الهاش ستبداء من هنا.

ايضا لديا سؤال لكم, هل تريدون استمرار المسابقة ان نقوم بأنهائها والدفع لمن فاز؟ ام تقترحون تغير معين في سير المسابقة؟

اضف على ذلك


بصراحة المنطق يقول ان كل هده البطاقات يجب ان تخضع لل KYC لان الامول ستمر على البنوك بطريقة او باخرى, وكل هده البنوك ملزمة بالتقيد بقوانين الدولة والبنوك المركزية, مما يعني انه من الطبيعي ان يطالبو ب KYC ولكن هل يقبلون جواز سفر دول عربية او لا فهنا السؤال, اما موضوع تقديم الهوية فهوا مفروغ منه من وجهة نظري.

This happens mainly to one of these reasons

1- The Sdcard you use doesn't work:

For some weird reasons, you might need to try a couple of Sdcards to get one that works with these control boards, once you find one, label it and hold on tight to it, also try to use smaller size Sdcards as they tend to have more success.

2- The Sdcard slot is dirty:

Just blow at it with your mouth, that should clean any dust in the way

3- The component that is responsible for the flash is bad:

This is more like physical damage that you can't fix.

Also, it's possible that you did not load the files the way you should, so it would be best to test on another control board if you have one.

In reality, all that matter is the number of hashes, so 8ph in 24 hours or 16ph in 12 hours or 32ph in 6 hours will all have the same odds, the only advantage of going with less hashrate for an extended period of time is demand affect on the nicehash market.

You should also know that nicehash renting is more of a pay-per-hash rather than pay-per-x time unit, so the fact that your hashrate has been less than 8ph for a couple of hours means that you have more balance to run beyond 24 hours (assuming prices stay constant and ignoring pool connectivity issues).

With the being said, the images of the orders show (fixed orders) which means that the hashrate should not fluctuate by much, when you use fixed order on Nicehash you essentially outbidding everyone else and you should always get the hashrate you asked for but I don't know what's going on with this particular case of yours.

perhaps that's when miners start to feel the heat, I mean even with 6.25BTC mining has been really tough, it's only recently when BTC price went up exponentially -  those who held coins made some nice profit, the few months following the halving were the worst months for many miners, rewards cut in half, the difficulty didn't drop, and the price wasn't going up, I can only imagine that many miners capitulated at that point in time.

When rewards are 3.125BTC mining would still be somehow okay to many miners, even if the price was below 100-200k, but when the rewards are at 1.5625 BTC price needs to be beyond those levels for mining to stay as decentralized, if not, then only those with free power will be able to mine at a profit.

With the being said, there might come times when bitcoin holders will need to mine for no profit just to keep the blockchain running the way it is, sort of like how many people run full nodes now without any financial benefits, but I guess it's too early to judge since we don't know how will the mining fees become like since they will be more important than the block reward soon.


I agree with the logic, 1M before we both (and perhaps most of the people that are in this discussion) are dead isn't a logical expectation IMO, but I don't think the term "wealth" is accurate here, money, as we know it, is merely a digit in a centralized database which is owned by the federal bank and the like, 18 trillion is a lot compared to what does it weight against real-world products and services today, but with the never-ending printing, one day it will sound and be small enough.

So out of curiosity, I was just checking the orders because I usually see folks rent on Sha256 when Sha256Asicboost is cheaper, and the two orders of yours are nowhere to be found neither on the EU nor the US hashrate market of both Asicboost and the normal Sha256, looks like nicehash closed them or something went wrong?
