That's pretty strange, when you use a new control board, it's like buying a new miner so this problem should have been solved, the only two things left to troubleshoot would be the fan 4 pin wire, it's a 2 pieces wires, the fan isn't directly plugged into the control board, so the wire from the control board to that junction could be faulty, the second thing would be the PSU, while the fans get power directly from the control board, that power still comes from the PSU, there is a chance that the power is dying/dead and can't feed enough power to all 4 fans.

🦊 Foxpup-III 🦊 now just BTC710! That's right: mere triple digits! Never before has this fox been on offer so cheap!
Shut up and take my BTC. 999 BTC cap loss for my tax return.
I wanted to get your VII but I am 9999000 BTC short. |

Weird, that address does not look like it's been mining at nicehash according to their dashboard lookup and looking at an explorer, the last time it received funds was January of last year.
Ignore nicehash dashboard it's useless, also this BTC addy belongs to nicehash, it's really more or less used as a username, and then you withdraw your BTC to your own wallet, so the process isn't traceable on the public ledger, of course, only nicehash know which mining address sent bitcoin to which address. OP, your miner is indeed infected, I am pretty familiar with this virus, although I don't recall the real name (I think it's called NightSwitcher) I do remember the nicehash hk, jp and the address looks familiar, so I am 100% positive. You will need to flash the hashboard using Sdcard, do that on a separate LAN, before putting the miner back online make sure you change the password and disable SSH, after doing so, your miners will be secured to a good degree, the only thing left to fix would be the PC/phone you use to access the miners, that's where the virus probably came from. If you want more security, get a cheap PC (the cheapest you can get), don't connect it to the internet, and use it exclusively to monitor and configure your miners. |

@MinerMEDIC, you don't seem like the kind of a person who would go through all this just to scam someone for a broken miner, judging by your post history you also seem to have some solid knowledge in the mining field, however, I still need to see someone trusted to vouch for you so I can add you to the list.
With that being said, feel free to keep your post here for now.

Welcome to the club, 99% of Bitmain 17 series gears' issues is similar to the one you have, in a nutshell, this is a dead hashboard and can't be fixed on a firmware/software level, you will need a set of tools and skills to physically fix the damage which is usually a loose heatsink/chip, you can find all the details you need in this topic, if you have more questions, feel free to ask. |

My guess is you can still use it if you clean the surface to ensure proper contact between the heatsink and the chip but to be sure I would reach out to wndsnb, he is one of the few members who have actually fixed a good number of hash boards and has probably faced the same issue. |

Are you sure it's 161? as far as I know, the error codes don't go past 40 something, can you post a screenshot? also have you tried to flash a different firmware on one of the gears that shows this error?

Mar 29 16:04:47 (none) local0.notice cgminer[442]: Chain 3 ASIC 0 !!! This part in the kernel log shows that all 4 hash boards are dead, so basically you have a dead miner and that's all about it, there isn't much you can do about it, but you could try a different PSU if you have one or custom firmware that might help revive a board or two. |

About that, I recently called the new Bitmain repair center that opened March 1st about repairing a bunch of broken APW9s. They told me that they were only doing in-warranty repair at the moment because they already have more requests than they can handle. And HM Tech is only taking business from people with 25 or more dead miners. All these repair centers have a constant backlog of 17 series miners waiting to be put back online.
and this is only in the U.S, so you can easily imagine the number of gears which have been fixed or in the process of being fixed in China, also the 1-2 cents power rate in the rainy season will allow the Chinese miners to overclock their old gears to the max, and that alone adds up to the considerable amount of hash power, the good news is that the effect of all this shouldn't last long, maybe 2-3 months, the other good news is that it gets harder and harder to move the difficulty to the upside. When we hit 200EH, 1% of that will be 2000000TH, that's 50,000 T17 or 20,000 S19, so to go from 200EH to 210 which is a tiny 5% (like the current epoch) we will need 100,000 S19, in today's aftermarket price that will be 100,000 * 10,000 = 1 BILLION dollars, it will be extremely difficult IMO to move the hashrate past 200EH, I might be too optimistic, or obviously biased. |

طبعا الاتجاه نحو الطاقة النظيفة هو من أهم الأمور التي تشغل بال المعدنين في العالم
انا كشخص اقوم بتعدين البتكوين وعلى مقربة من الكثير من المعدنين منهم الصغار والمتوسطين مثل حالتي ومنهم حيتان كبيرة تمتلك الاف المعدات, قمت ايضا بالاشراف على تصميم وتنفيد مزارع تعدين كبيرة تكسب الاف الدولارات يوميا, يمكنني ان اجزم لك ان المعدنين اخر همهم الطاقة النظيفة ويعتبرونه كلام فارغ ومضيعة للوقت. التعدين مبني على شي واحد فقط وهوا الربح, اين ماوجد المال وجد المعدنين, السبب الوحيد الذي سيجعل المعدنين يتجهون للطاقة النظيفة هوا في حال انها كانت ارخص من بدائلها, ان كانت اغلى حتى بمقدار 10% فلن يقومو باستخدامها, ولك خير دليل في الصين التي تمتلك الغالبية العضمى من اجهزة التعدين. في شهر ابريل وحتى شهر سيبتمبر يبدا موسم الامطار هناك ويقوم المعدنين بنقل اجهزة التعدين الخاصة بهم الى Sichuan الغنية بالانهار والطاقة النظيفة, طبعا هده النقلة لاتنبع من حب البيئة بل لان سعر الكهرباء هناك اتناء الامطار يتراوح من 1 سنت الى 2 سنت وهي تعتبر رخيصة جدا, فور توقف الامطار وانخفاض مستوى الماء وعدم قدرة التوربينات على توليد الطاقة يعود المعدنين بمعداتهم الى مناطق اخرى مثل مانقوليا الداخلية و شينزين, الجدير بالذكر ان معظم المزارع تعتمد على الفحم وهي اكتر طريقة ظارة للبيئة اكتر من الغاز والديزل والمفاعلات النووية واي مصدر طاقة اخر, طبعا لان الفحم ارخص مصدر للكهرباء بعد الرياح والامطار. الشاهد هنا انا المعدنين يسعون وراء ارخص مصدر للكهرباء سواء كان الانظف والاصدق للبيئة او العكس تماما, فالامر لايهم وهدا امر منطقي جدا فمنذ اللازل هكدا هي غريزة البشر, الشركة هده التي تدعي حبها للبيئة فاما انها كادبة او انها تسعى للربح من وراء التظاهر بحبها للبيئة والحفاظ عليها, او ان تكلفة الكهرباء ستكون ارخص في موسم الامطار تماما مثل مايحدث في الصين. السؤال الذي يطرح نفسه, عند انتهاء موسم الامطار او توقفها لاي سبب هل سيبقون اجهزة التعدين التي تجني ملاين الدولارت خارج الخدمة حتى نزول الامطار؟ ان فعلو هدا يعني انهم سيخسرون المال ويتجهون للافلاس عاجلا ام اجلا, ان اتجهو لمصادر اخرى يعني ان نوايهم حول الحفاظ على البيئة هي كاذبة, لذلك دعنا نجلس ونشاهد ماتئول اليه امورهم. |

اخي اولا مرحبا بك في المنتدى, تانيا هدا القسم مخصص فقط للمواضيع العامة مثل التشفير والمحافظ وغيرها وطبعا اي شي اخر يخص البتكوين, سيتوجب عليك نقل الموضوع الى قسم العملات البديلة والموجودة في هدا الرابط https://bitcointalk.org/index.php?board=242.0يمكنك نقل الموضوع بالدهاب الى اسفل الصفحة واختيار move topic. بالتوفيق. |

My questions, should I even bother?
Does it worth anything?
Unless someone wants to add it to their " museum" it has zero economical value, it hashes at 0.67TH and draws a modest 400w to do that, just to give you a reference, the newest gear S19 pro consumes below 30w per terahash so that's 20w vs 400w, which is 20 times more effienct. |

و هذا برأيي هو معنى التبني الصحيح للبيتكوين وليس فقط محاولة الاستفادة منه ضرفيا: Tesla is using only internal & open source software & operates Bitcoin nodes directly.
Bitcoin paid to Tesla will be retained as Bitcoin, not converted to fiat currency.
اخي خالد هل يمكن ان يكون معنى هدا الكلام عكس ما فهمناه؟ كلمة retained والحاق not convereted يمكن ان تعني انهم لم يستعينو بأحد بوابات الدفع التي تقبل بتكوين من الزبون وتقوم بتحويلها لدولار فوريا, ولكن هدا لا يعني ان شركة تيسلا ستقوم بالاحتفاظ بالبتكوين لفترات طويلة, من الممكن جدا ين يكون استعمل هده الوسيلة لشراء البتكوين بطريقة غير مباشرة, هدا لا يعني انهم ليس لديهم هدف معين من حيث السعر مثلا يبيعون كل شي عند سعر 80 الف دولار. انا لا اناقش شخصية elon وكونه يختلف عن الباقية, ولكن شركة تيسلا وغيرها لديها ناس مختصة تلجاء لها في استتمارها, ربما يقوم elon بشراء بتكوين من امواله الخاصة ولكن لايمكنه فرض سياسته على الشركة, ربما اكون مخطاء ولكن انا اعتقد ان جميع الشركات التي قامت بشراء بتكوين سوف يقومون ببيعها عاجلا ام اجلا, وعندها سنشهد انهيار في الاسعار ونعيد نفس سيناريو 2017 ليقومو بالشراء مجددا باسعار منخفضة من البسطاء الذين يشترون عند القمم. |

Nice finding, I liked the research, especially because matches what I have always thought, mining outperforms holding in side-ways and bear markets, holding outperforms mining in a bull market, this is the general rule of course with some exceptions such as your power rate and or the price of the gears you buy/sell.
The study also proves another point which is the "sell daily", it has the most profitable outcome for the majority of the time, it also proves that the theory which states " you should mine at a loss and hodl bitcoin" will almost always make you lose money".

it might be that finally there is a serious batch being delivered?
It's actually a combination of a few unfortunate events, new gears are being delivered, many old gears have been fixed, the rainy season in China, and perhaps the arrival of gears shipped by sea which takes up to 2 months depending on the origin and the destination. These events will contribute to increasing the difficulty at a higher pace, and this should last for a few months, however, with the current price of bitcoin, it doesn't matter the difficulty does, 2021 will still be a lot better than 2020 for miners. |

Do this while testing them one by one and maybe the reason for this is because of overtemp that's why all hashboard acting dead.
This is unlikely to be the case, in fact, it's almost impossible, the reason is that during the initial chip-count the fans will be spinning at 100% and the heating process has just started, actually, the time it takes to count the chips is too short that you can even get away with no fans at all, 0 asic problem is almost never a temperature-related problem. |

Apologies, quick question and excuse my ignorance. I am looking into solo mining so I was wondering if you what you've suggested is also good for solo mining in order to avoid duplicated nonce guesses?
Why do you even worry about the nonce thing altogether? each mining instance will get a different template from the pool, and then the miner itself will adjust the extranonce2 as it pleases, and then you have the timestamp which adds up to the making of the Merkel root which creates a whole new world of possibilities, it's good that you want to learn about these things just for the sake of knowledge, but these "problems" are from the past and they have been solved for good, just pick the pool you like and mine on. |

و كيف اعرف ان كان المشروع مقبول و له قيمه او لا
لايمكنك الجزم بقبول المشروع من عدمه الا بعد التجربة, عندما تخطط لانشاء مشروع مبني على فكرة جديدة فأنه لايوجد اي مرجع لتقيم نجاحه. و هل الافضل العمل على المشروع وحدي او البحت عن اشخاص ليتبنوا هذا المشروع
ان كنت تمتلك رأس المال فبكل تأكيد الافضل ان تقوم بالاشراف عليه بنفسك وتقوم بتوظيف العناصر المطلوبة للمشروع, "بيع الافكار" ليس بالامر السهل. برأيي فكرة المشروع هي الأهم، يجب أن يكون لديك فكرة جديدة وغير موجودة حاليا والناس بحاجة لها فعلا حتى تستطيع النجاح.
اختلف معك قليلا اخي يحى , هناك احتمال كبير بنسبة 99.99% ان اي مشروع تفكر فيه فهوا مشروع موجود او على الاقل تم تناوله في العلن, العبرة ليس ان تأتي بفكرة جديدة بل العبرة في تطويرها وحل المشاكل المتعلقة بها وتنفيد المشروع بشكل مثالي, كل المشاريع التي ظهرت هدا العام مثلا هي مشاريع لافكار قديمة, ولك خير مثال في مشاريع ال المنصات الامركزية Dex, الجميع يتحدث عنها منذ سنوات ولكن الفريق الوحيد الذي نجح في تنفيد هده الفكرة بطريقة ممتازة كان فريق Uniswap بالرغم من وجود عشرات المشاريع المشابهة. |
