I am under the impression that he means the complete the list of Myrig repair centers, they do state the following countries on their website (U.S, Russia, Ukraine, Venezuela and Japan) but no address are available.

With that being said, please make sure you double-check the address with any repair service before sending the gear to them, just to avoid losing the gears forever or face some delays in the best-case scenario.

لا اتفق معي اخي بالرغم من ان كلامك حول سرقة وحجز الهواتف صحيح, ولكن هدا ينطبق على الابتوب, او جهاز الحاسوب او حتى الهارودير والت, لذلك وان قلنا ان ضياع تلك المحتويات او الحصول عليها بالقوة من قبل العصابات او السلطات هوا ممكن لكل شي بدون استتناء فعندها يمكننا تجاهل هدا العامل كليا والتركيز على مستوى الحماية الثقني فقط, وهنا سنجد ان محافظ الويب هي الاكثر خطورة.

طبعا من المنطقي جدا ان اي شخص يضع اموالا يخاف عليها في محفظة على الموبايل ان لا يتجول بالموبايل ويعرضه للضياع بل يجب ان يحافظ عليه في مكان امن, واي مبلغ "كبير" نسبيا للشخص يجب ان لايكون على محفظة "ساخنة" من الاساس.

What is that 49 cents or 4.9 cents? if it's the latter then you have got a very decent power rate, if it's the former, no luck.

I think the only question that matters is how much do miners in China pay per Kwh, I honestly can't find any rationalism in mining bitcoin if your rate isn't close to those in China, one might get away with a bit of difference but if it's more than double, they should just forget about mining altogether.

We know the average price in China is anywhere between 1-5 cents depending on the season, to be on the safe side, you should work with 3-4 cents, if your power rate is around that or slightly higher (maybe up to 6-7c) you have a good chance of making a profit in the long run, if your power rate is 10c or higher, you will need a lot of luck to be profitable and once you redo the math you will figure out that in most cases, you would have made more profit by simply buying the coin directly.

So you are expecting the Chinese to send their mining gears to your "farm"? The mining ban fud has been going on since 2017 or probably earlier than that, mining generates a huge income, the Chinese government gets a good chunk of it, mining in China will not stop.

Even 1000 miners aren't good for solo mining, in fact not even 10 times that amount is "safe" for solo mining, and as the hash rate grows, you will face the risk of never finding a block for the lifespan of those gears, honestly, at this point, it's safe to assume that nobody can solo mine, at least, not those who have to ask the question, there are probably a few entities out there who are capable of solo mining ( you can probably list them in less minute or so) but we all know those won't be asking such a question online.

Check the pinned thread regarding Asic miner repair services, I have updated the list and added Myrig to the list after they have been vouched for by a few members, of course, I am not responsible for any loss you may encounter, I am trying to maintain a list of services for the community to use and I do my best to list only the trusted services, but you should deal with everybody mentioned there at your own risk.

If this was the case, why would anyone use 220v over 110v, you pay your electrical bill based on the KwH consumption which is directly related to the wattage, it would be cheaper to get a step-down transformer and run everything at the lowest voltage possible.

As Haqqs mentioned, electrical engineering is complicated, electricity consumption on the other hand is rather simple, if it says 1000w on the label and assuming it's accurate, it will always print 1000w on your meter regardless of the voltage, the voltage will affect the amps (lower voltage = higher amps).

But if you are interested in calculating the amps (which is pretty irrelevant for this case) I = W / V where I is the current in amps, W is the wattage and V is the voltage, so if something consumes 220w on a 220v circuit, it will draw 1 amp, if you run it on a 110v it will draw 2 amps (220/110 = 2), but of course this is sort of oversimplifying the subject to give you the general idea.

Ignoring the breaker issue and assuming the breaker trips because it was too small for the current needed, based on my own experience, it's very common for a single fan to stop the whole PSU from working, you have 2 fans next to each other and 1 fan which is on the other side, the one which is located alone should be working fine, the other two both need to be good to spin, so what you can do is use the plug from the single fan to test the other two fans, if all 3 fans are good you need to replace the PSU, otherwise, if one of the fans is bad you just replace the fan.

I added Myrig to the list of services in the U.S, I tried getting their address but nothing is mentioned on their website, which state/city did you send the miners to for repair?

لا ارى اين النصب في الموضوع, لا اعتقد ان ايلون استفاد اي شي من اخر تغيردة, وثم انه لم يعد احد بأن سعر البتكوين سوف يرتفع, من المضحك ان يجد الناس شماعة يعلقون عليها نتائج قرارتهم الخاطئة, نحن في هدا المجال قبل ان يتكلم عنه ايلون على الاغلب قبل ان يسمع عنه, والكثير من الناس كانو يتجاهلون الكريبتو ولكن عندما تكلم عنها الون قفزو لشرائها متجاهلين كل ميزات ونقاط القوة للبتكوين ولكن فقط لانهم يركضون وراء ال hype ومن المنطقي انك عندما تشتري عملة بعد صعودها بنسبة 1500% يجب ان تتوقع الخسارة.

البتكوين زارت مناطق ال 3000$ مرتين, بقيت تحت ال 10 الاف لاشهر, من تجاهل البتكوين في تلك الايام ويشتريها ب 60 الف فقط لان ايلون تكلم عنها فأنا اسف لقولي ان هاؤولاء الناس سدج واغبياء, انا لا ادافع عن ايلون ولا يهمني, ولكنه ليس السبب في سقوط السعر وان كان هوا السبب فهل يعني اننا مدنيون له عندما صعد السعر؟ ان كان هوا السبب فقد تسبب في صعود السعر ونزوله وهنا اصبح رصيده لدينا صفر, يعني في كلتا الحالتين موضوعه لايهم والبتكوين اكبر منه بكثير.

بالحديث عن الشراء في القمم, انخفضت البتكوين اليوم الى 30000 الف وبعض المنصات سجلت 29 الف وكسر, هل اشترى الناس المساكين الذين ضحك عليهم ايلون بهده الاسعار؟ بتأكيد لا, سوف ينتظرون صعود السعر مجددا والشراء في القمة والعذر دائما موجود.

كلامك صحيح اخي خالد ولكن دعنا لا ننسى انه من عدة اشهر كان سعر البتكوين اقل من 10 الاف دولار, ولو رجعنا للماضي وقلنا انه بتاريخ اليوم سيكون سعر البتكوين 40 الف لما كان هدا ليكون سهل التصديق, ان تجاهلنا الصعود الغير المبرر والسريع لمستويات ال 60 الف واعتبرنا اننا قد وصلنا لل 40 الف للتو اعتقد ان الجميع سيكون راضي عن اداء البتكوين ويقبلها كويسلة دفع استنادا على ان سعرها على المدى الطويل يتجه في اتجاه واحد وهوا اتجاه صاعد.

المشكلة وكما ذكرت في تعليقي السابقي


انا ضد فكرة ان اموال الشركات اهم من اموال عوام الناس تأثيرا على السعر, والسبب الرئيسي هوا عدم قدرة الشركات على الخوض في استتمارات تصنيفها "خطير" وبالرغم من ان السعر بالمجمل صاعد الا ان السعر قد يستمر في الانخفاض لسنوات قبل ان يعاود الصعود, الشخص العادي مثلي ومثلك يمكن ان يستتمر مبلغ معين لايحتاجه وينساه لفترة 5 سنوات, اما الشركات لايمكنها القيام بهدا الشي, وكما قلت في تعليقي السابق من عدة اشهر انه لايجب الانجرار وراه هده الاخبار ويجب عدم الثقة في الشركات فهي سوف تبيع بمجرد حاجتهم للمال او بمجرد ارتفاع السعر وتحقيق ارباح.

Well that's an improvement, you went from a complete dead miner to 1/3 of the total hashrate


Chain 2 is likely dead and it is not much you can do about it, chain 0 shows all 65 Asics but has a temp-sensor error, the temp-sensor error is mostly not due to a temp-sensor but rather a bad chip or a bad PSU, the same thing could apply for chain 2 since now chain 1 is hashing well, we know the PSU is good for at least 1 hash board, what you should do is unplug chain 0 and 1 and run chain 2 only, then unplug chain 1 and 2 and run chain 0 only, this will ensure that the issue isn't PSU related.

The majority of the time it's the chips themselves the fail, usually 1 chip at a time, and the way these hash boards are made, 1 bad chip will stop the whole hash board from mining, replacing the chip will need a few tools and a bit of skill, there are many topics around here related to that, youtube also has a ton of videos, and if you want the techy stuff - head to Zeusbtc and download the S9 repair manual.

With that being said, if you have no previous experience fixing electronics, it will be very hard to worth with these hashbaords.

This does not change the fact that you are trying to sell your mining gears here without accepting escrow and without having any history around here, with all due respect, to me, you are more likely to be a scammer than a legit seller, and I am sure most folks would agree.


Alibaba is far from safe, while it's unlikely to be directly scammed, the gears most sellers on Alibaba will send you will be either not what you paid for or defective gears, getting the seller to refund you the money will be a nightmare, and the safe-trade or trade-assurance b.s will only work if you are a Chinese, it will be extremely difficult to get Alibaba to stand with you against a Chinese seller, if you want to take that risk, it's on you.

There is no such thing, you are guaranteed to get paid the amount agreed on when the escrow is done with their part, the price fluctuations are irrelvent.


Anyone can create such a list, it means nothing and it's worth exactly nothing.


Account rank can be irrelevant, many of the old era legendary accounts changed hands a dozen times, I am not sure why do you have to mention that your alleged clients registered here before me, it's off-topic, but just to piss you off I would like to let you know that I am top 10 most earned merit, DT member and highly trusted, my account is more trusted than a dozen other legendary accounts combined, and even with that - I don't go around the forum selling mining gears without offering the option of escrow.

I do not care who your clients are, if you are counting on getting a vouch from 1 or 2 random legendary members that nobody around here trusts - it will be useless, those accounts are sold for pretty cheap all over the internet, if you are going to bring someone here to vouch they need to be trusted, there is probably less than 50 members whose vouch will count, the rest will be useless and you still have to use escrow if you want to sell your stuff here.

But nobody here knows you, it's safe to assume that it's pretty risky to deal with you, the majority of asic miners sellers are scammers, so this is nothing personal, you should offer the use of forum escrow or cash-on-delivery if you are serious about selling your miners.

Please use the code tag to post kernel log, it looks terrible this way.

It appears that this miner might have mixed hashboards with different EPROM data, what you should do is try to run the miner with 1 hash board at the time, or use custom firmware like Vnish which ignores the EEPROM.

I don't that is possible without a tester/fixture tool, my understanding is that the current won't flow in the hashboard without a control board, and the normal control board will only supply the hashboard with power for a very short period of time, it will stop once the asic count fails, so you have a very short window to test, I am not sure if that is doable, but I guess it is if you perfectly time when does the current flow based on the kernel log or x seconds from powering on.

The main feature of the fixture tools despite their brand is that they keep the current on the hash board for as long as you want it to be there so you can measure the voltage around the chips, I think it would be best to reach out to wndsnb to confirm the above.

It has been a while since I played with these gears, but IIRC they will always display the same chain, it would be best if you just troubleshoot them 1 by 1 to avoid confusion.





There is a tiny chance that the PSU is faulty and causes this, but it's not very likely to be the case, it's very common for a dashboard to show 30 Asics and then after a reboot, it will show 3 or 0 Asics, so this could very well be just a coincidence, this is why it's ALWAYS best to test 1 board at the time, so now since chain 1 (previously showing 21 Asics) is showing 30 Asics, let it run alone for 12-24 hours, if it sticks and nothing goes wrong, you can be somehow sure that it has been fixed and then put it aside and start with chain 3 doing the same process all over again, testing the board for a few mins can be misleading and will give you a lot of false results.




Do you mean voltage? if it's what you mean then it is 21v DC.

This could be a faulty control board, but in my years of mining I have never come across such an issue,  the likelihood of a control board that works okay with 2 chains and the 3rd chain is bad is just too low, did you try the 4th slot? the control board has 4 places on which you can attach the ribbon/data cable into, there is an empty one since the T17 has only 3 dashboards, can you try to use that port and see if you get any different results?

Also, make sure the busbar is firmly put, and the screws are tightened, if either the positive or the negative is even slightly loosen the dashboard won't show up.
