If all 12 units stopped hashing at the same time then it's likely a pool/network-related issue, can you try a different pool? I don't have AvalonMiner but with Antminers you can ping the pool using the miner, I suppose Avalon would have even more network troubleshooting tools.

انا ضد شراء هده الاجهزة لعدة اسباب, اهما هوا معدل الزيادة في مستوى الصعوبة, طبعا يمكن ان تقول ان هدا الشي ينطبق على البتكوين  ايضا, هدا صحيح ولكن النقطة التي لا يقوم بحسابها اغلب المعدنين الجدد هي "سرعة" زيادة الصعوبة, وهنا يأتي جمال الرياضايات والارقام.

لو اخدنا عملة KDA فان الهاش ريت الحالي لها هوا حوالي 9 بيتا هاش اي 9000 تيرا, احد اجهزة الاسك وهي التي تكلمت عنها حضرتك KD5 يمكنه تعدينها بقوة 18 تيرا, مما يعني اننا تحتاج فقط 500 جهاز لمضاعفة الصعوبة اي خسارة نصف الدخل.

لو قمنا بنفس هده المقارنة على البتكوين, الهاش الحالي 130 اكسا هاش, اي مايعادل 130,000 بيتا هاش, او 130,000000 تيرا هاش, لكي نقوم بمضاعفة الهاش ريت باستخدام احدث اجهزة التعدين مثلا بهاش 100 تيرا لكل جهاز نحتاج الى 1,300,000 جهاز , مبدئيا لايوجد شركة قادرة على تصنيع هدا الكم خلال فترة سنة او حتى سنتين, وحتى ان زادت هده الشركات قدرتها الانتاجية فأن تكلفة هده الاجهزة بسعرها الحالي في الاسواق 10 الاف دولار للجهاز اي حوالي 13 مليار دولار, من شبه المستحيل ان يحدث هدا الشي في فترة قصيرة, بينما فرصة صناعة وبيع 500 جهاز KD5 او حتى 5000 جهاز فهي واردة جدا ويمكن ان تحدث في اسبوعين او شهرين.

لذلك تجد ان دخل هده الاجهزة في البداية يكون عالي جدا حيت يصل الدخل احيانا الى الاف الدولارات في الاسبوع الواحد, ولكن فور استلام اول دفعة تجد ان الدخل انفخض بنسبة 90% او اكثر, فأن لم تكن من اول الاشخاص الذين تحصلو على هده الاجهزة (وهدا امر شبه مستحيل لان الشركات المصنعة في العادة تحتكر هدا الشي) فأنت على الاغلب سوف تخسر.

طبعا يوجد شواد لهده القاعدة فمثلا يمكن ان يرتفع سعر العملة 100 ضعف ليعوض تضاعف الصعوبة, فمثلا اجهزة L3 لتعدين لايت كوين ودوق كوين كان دخلها اقل من دولار ليقفر فوق ال 10$ عندما ارتفع سعر عملة دوق كوين وهنا قد استفاد كل من يملك اجهزة تعدين لايت كوين وقامو بجني ارباح طائلة, ولكن هل من العقلانية ان تستتمر اموالك وتتمنى حدوث شي غريب مثل هدا؟  لقد شاهدانا مئات العملات التي تفقد 99% من قيمتها بين يوم وليلة, عند شرائك لجهاز تعدين عملة معينة فأنت تراهن على بقائها ونموها وايضا ارتفاع سعرها, لذلك بالنسبة لي فالخيار دائما سهل, بتكوين او ايثيريوم هم فقط العملتين التي يمكن ان نقول عنهم مضمونات وصعوبتهم وصلت لارقام يصعب تحريكها للاعلى بنسب جنونية, والخيار بين البتكوين والايثيريم ايضا سهل وهوا يرجح البتكوين, الا طبعا في حال انك لاتستطيع شراء اجهزة اسك وتريد استعمال كروت الشاشة فعندها الايثيريوم افضل (بالرغم من ان الايثيريوم سوف تنتقل الى POS يوما ما على اي حال).

Would you explain more about "cold solder" did you find some solder balls shorting some legs/pins? it would be great if you could share some more info (photos would be really nice).

What firmware is installed on this machine? can you test with custom firmware like Vnish or BO+ ? I prefer the former, you can get it on Asic.to or AwoesomeMiner website (both have some fees 2-3%), these custom firmware "ignore" some things that the stock does not, there is a good chance that the miner might work with custom firmware.


Great that you chimed in, what does the pattern test actually do aside from counting chips?

يبدو ان احد ما يحاول التحايل عليك, كن حذر وتأكد ان الرسالة فعلا جائت مني, رابط قناة التليقرام التي ارستلها لك هوا https://t.me/minerexpertsales ومديره اسمها grace وحسابها على التليقرام هوا @gracezhou1993

الكثير من المحتالين يستخدمون اسامي تشابه اسامي ناس موثوقة لكي يتحايلو على ضحايهم, يجب عليك دائما التأكد انك تتحدث مع الشخص نفس, كأجراء احتراجي في حل قررت ان تشتري قبل تحويل اي اموال يمكننا التأكيد معي, ربما يمكن ان ترسل لي العنوان الذي طلب البائع التحويل اليه واقوم بالتأكد منه ان كان فعلا عنوان ينتمي له او نجد اي طريقة اخرى للتأكيد المهم انك يجب ان تكون حذر فمستوى النصب في هدا المجال يفوق الخيال, ايضا اريد تذكيرك بما اخبرتك به في الرسالة انه وبالرغم من اني تعاملت مع grace عشرات المرات واعتقد انها اهل للثقة الا اني لا اتحمل مسؤولية اي شي قد يحدث بينكم لا سمح الله.

كنت اميل الى كوننا نعيد سيناريو مشابه ل 2016-2017 ولكن مع مرور الوقت في هده السايكل وخصوصا بعد الهبوط الاخير تبين لي انني كنت مخطاء واننا على الارجع سنعيد ماحصل في 2013, يعني اننا في "بير ماركت مصغر" ان صح التعبير, واتوقع ان يستمر السعر تحت 40 الف لاشهر ربما حتى نهاية السنة او الاشهر الاخيرة منها قبل البدء فعلا في التحرك الى الاعلى, في نفس الوقت لا اعتقد اننا سنرا مستويات ال 10 الاف وغيرها.

اعتقد ان الضرائب في تركيا على الاجهزة الالكترونية عالية جدا وربما يتم مصادرة اجهزة التعدين, والاهم من كل هدا ان سعر الكهرباء في تركيا مرتفع ولن يكون التعدين هناك مجدي, ارجو ان تحققك من كل هده المعلومات قبل المخاطرة لكي لاتتعرض للمشاكل.

في حال لا زلت تصر على الشراء ارسل لي رسالة على الخاص وسوف ارسل لك حساب تليقرام احد الباعة في الصين ويمكنك التواصل معها مباشرة.

It's pretty normal for the miner to show socket connection failed when it's booting, don't worry about that.




Seems like the voltage is a bit too low, it's likely that you have a bad PSU, can you confirm if all 3 fans on the PSU are spinning? also can you test 1 hash board at a time?

You are still wrong, most used miners come blank as well ( most sellers don't want to reveal their pool and worker details), so the chances of whatever you are claiming to happen are slim to nothing.

According to one of the Chinese miners I know, the government wants to tax the electricity used for mining, as funny as it may sound the government told miners in some regions to shut down for a while until the new electricity law gets implemented, so far the rumors are 10% tax on power, which isn't large by any means.

But regardless, all of the mining gears will have to find another home, it's only a matter of time before everything gets plugged in, I personally think the whole China news is irrelevant and that the market price could not care less.

The price has been overextended for months, if you follow my posts in the mining post I have been telling people not to buy over-priced mining gears because that price was not sustainable and a huge drop will have to come, I don't take credit for it because I have no invited the wheel, anyone who understands the basics of the markets understands that, but some people think everything is just random.

Now my projection for the price is that we did indeed hit the bottom of the correction or at least came very very close to it, all those 5k and 15k calls are likely going to go with the wind, I, however, do not believe that will go straight up, this will probably be one of the longest bear traps in bitcoin's recent history, we could very possibility extend the cycle for another year, people who are expecting 100k this year will probably be wrong, I hope that I am wrong, but I can't think of any other scenario except a for a boring market that will take months to change, regardless of what China, Elon or Trump has to say about bitcoin.

Wrong, since the lawsuit against Bitmain in 2018 all of their miners today (and most other miners) come blank and the miner won't start mining until you enter your pool and worker details.

While I don't use Slushpool anymore, I did contact someone from their team whom I was in contact with regarding some issues with BO+, he responded pretty quickly and told me that someone will attend to you guys ( I sent them the topic URL), I don't use Slush nor their firmware anymore, but I do have faith in these folks, I think they are genuine and they will refund your funds, but if they don't - I will be the first person to tag their account and support the "victims" of this incident after having heard from both parties.

With that being said, let's just hope that things will work out smoothly.

نعم يوجد العديد من البرامج, اشهرها هوا AwesomeMiner طبعا هده البرامج ليست مجانية ولكنها ايضا ليست باهضة, في حال كان لديك عدد كبير من الاجهزة فهيا ضرورية جدا اما ان كان العدد بسيط فيكفي فقط مراقبتها عبر تطبيق الحوض في الهاتف المحمول حيت انه ستصلك رسائل تنبيه في حال انخفاض الهاش ريت لاحد الاجهزة.


لاي بلد تريد ان ترسل اجهزة التعدين اخي؟


ملاحظة: حاول ان تكتب اسمي في تعليقك حتى يصلني اشعار لانني انسى الرجوع لبعض المواضيع هده الفترة خصوصا لاني مشغول جدا.

Where did he say he was located? he is most likely trying to scam you, these prices are way too low, the lowest this gear went to was about 3k when btc fell to 31k before the difficulty adjustment ( which was the cheapest time to buy a mining gear for weeks), today, it's priced at about 3.3-3.5k, these are China prices which are in theory are the cheapest.

When someone offers you a 3k gear for 1.8k you should be extra careful, there are a few legit sellers in this forum such as grace, Scott, and kaboomrack, even if you don't buy from those guys at least check their prices against the other buyers if the price is way too cheap - you should probably avoid it, there are probably 10 scammers for every single legit mining gear seller, keep that in mind.

Given Slushpool's reputation, I highly doubt they will "steal" people's funds this way, have you contacted them? what did they say? I believe Artemis3 is an ambassador for BO which is also Slushpool in one way or the other, perhaps he should be of some help.

Just so we don't go with interpretation of what "set-up" means, and judging by the OP, it's pretty clear he means some installation of a certain software/firmware, which in that case, you are wrong because all miners today are indeed pre-set.



The asic miner in the link you posted is T9+ by bitmain, yes it comes ready to mine, all you have to do is fill these 3 fields




The password is usually just "x" for most pools, the URL is something that the mining pool you join will give you, and the worker name is something you set in your pool account, pretty straightforward and takes no more than 2-3 mins to get it up and running.

With that being said, 1.2k for antminer T9+ is way too much, this gear is now worth about $200 or less in China including a PSU, so the max you should pay for it should be below $300, it's not effienct and if your power rate is above 2-3 cents you won't be making any profit, and it runs pretty hot as well, but it's a good learning object if you just want to start with it, however, do not expect to become rich mining with that old gear.

There are test points (CLK-CO-RI-BO-RST) which you can use to test the chip without having to remove the heatsinks, this is the repair manual for the S17+, the same website is also full of other tutorials, one thing to keep in mind is that if you are using the fixture tool you must NOT use an external PSU to test the hash boards.

All bitcoin miners as of today come with their own software pre-installed with a web access and a simple GUI, you just need to enter your pool and worker details and start mining right away.

If you have any device that needs some sort of software then it certainly can't mine bitcoin in the first place.

I did conduct long research on this problem a year ago, more details can be found here, long story short, the temp sensor error is very rarely the result of a bad temp sensor, which makes perfect sense because what are the odds of 4 temp sensors falling at the same time? slim to nothing if you ask me.

Your problem is a bad chip (or a few of them), we do not "yet" know why some chip failure causes the miner to report a dead temp sensor but we are certain that is the case, if the fixture tool did not help with identifying the exact chip, you will need to manually measure the volage/resistance across all chips.

If the temp-sensor error shows on all three boards (you get a total of 12 temp sensor errors) then that is just a bad PSU.

If it was this simple, nobody would mine bitcoin in the U.S, China, or any other region, everyone would move to a country where power is dirt cheap and we all will become millionaires, unfortunately, the world does not function this way.

Most places that have cheap electricity have other major issues which most people rather not go through, the majority of those countries are pretty corrupted, so just because the power is cheap it does not mean the mining operation itself is cheap, you will still need to bribe some cops, mafias or a militia to be able to mine safely, and even if you were okay with that route then your operation needs to be either so huge that you can afford to keep those folks happy or too small to stay under the radar, in other words, you need a lot more than just 60-70k.

On top of that, you will need someone to get you there, a partner who will ask for a huge cut without sharing any risk or investment with you, there is so much to be said about this, but in short, those cheap rates are not for everyone and the average joe should not even think about it.

What's more important than that is the fact that mining isn't a no-loss business that will secure your financial life at no risk, I have almost free power, and yet I have encountered some serious losses in my mining investments, there is a lot that can go wrong, the power bill is just one of so many other things you need to worry about, add to that the fact that by next halving or the following if bitcoin price fails to reach super high prices the profitability of mining will just keep going down.

It might be okay for some people to consider mining bitcoin (despite the fact that most folks lose money and are better off just buying the coin) but moving to a new country just to mine bitcoin is one of the worst ideas I have heard this year.

Care to explain how is your mining pool going to be decentralized? I don't think anyone has issues with centralized pools since 99% of pools are centralized anyway, I just don't like seeing the word "decentralized" used for marketing purposes like that unless your pool is something like p2pool then please refrain from using that term.
