I don't think that is confidential information, assembling thousands of miners isn't something you can keep a secret, unless specified otherwise by my source then i will not reveal the information.

I stand corrected then, I confrimed from a Malaysian source that Bitmain does indeed assemble some of it's miners in Malaysia, still "assembly" is quite a broad word as in we don't know to which level of assembly they go to.

I still think the quality isn't very different because 90% of the issues that all of these 17 series gears have in common is the thermal paste/solder, whereby the whole chip fall down or just the heatsink drops (both lead to a none-working hash board) I highly doubt soldering the chips nor glueing the heatsinks on them is done in Malaysia, it's more likely that they receive ready to use hash boards, control boards, PSUs and a bunch of screws and all they do is put them all together, and just by doing so, you can't really harm the hash boars unless you intentionally do it, and even then, you need a lot of time and effort.

on the other hand,  if the assembly goes to a much lower level like soldering the chips and all, then the difference in quality will vary greatly, however, all the 17 series gears I ordered came from China, and the quality is terrible overall, so I still believe it's a matter of luck after all.

I shall confirm what does actually happen in the warehouse of Malaysia in a few days, will keep you updated.

As far as I know, Bitmain doesn't make any mining gears in Malaysia, it's probably just a sorting hub to reduce import/tax costs for countries that aren't so friendly with goods coming in directly from China, what happened to you was probably nothing but a bad luck with one of the batches, Someone said that the recent batches are slightly better build as far as the thermal/glue is is concerned, which does make sense.

Please keep us updated with your attempt to fix this broken S17 pro, if possible, describe the issues you are facing just in case someone had the same problem and they could help you fix it.

That's true in your specific case, I was taking about the general use of these PD adaptors since they are two-way connection like how NFW explained here:


In other words, if you plug in your phone into your laptop or tablet, your phone can charge your laptop, but since your miners won't have any other source of power like battries or so, then please ignore this whole part.

---

What I don't understand about this whole PD protocol is the way it "negotiate" the voltage needed with the plugged in devices, in the article that NFW linked it says:


We know that PD can output 5V, 9V, 12V, 15V, 20V, so without exchanging some sort of data/signal between the headsets and the USB PD, how is it possible that you can charge different devices which require different voltages?

How about using something like this and your miner has two USB ports, one for charging and another for data? or one USB port for charging and another ethernet port for data?

That seems like it, most USB C ports I have seen are only for data transfer, they don't even support video output, there might be a mobo or two that support both but I am pretty sure they are pretty limited and can't be targeted as potential clients for your miners.


That could work, althought the cost of that thing might be a bit too much, another potential problem is that this will be capped by the power source, many PD adaptors can do up to 20v/5a but that doesn't mean all devices you plug it to will be able to provide that.

That's a good point, but actually, if he indeed flashed the latest firmware then he is stuck with it, in other words, migrating to another firmware for testing purposes won't be as easy because Bitmain did pretty "well" locking these miners with the latest firmware.

I am also eager to hear from OP, I still think it's either a power-related issue or the miner is dead ( all hash boards are dead), I hope the former is the case.

في الواقع منصة Unsawp هي احد الاسباب الرئيسية لزيادة رسوم التحويل على بلوك تشين الاثيريوم, نظرا لان البيع والشراء في المنصات الامركزية يتطلب فعليا حدوث التحويل transaction على البلوك تشين بعكس المنصات المركزية حيث ان كل هده التحويلات تكون محلية في قاعدة بيانات واحدة ولا تكلف شي تقريبا.

ونظرا لموضوع الستيكن والمكسب الذي يأتي منه فالمستخدمين لايمانعون دفع هده الارقام, في الواقع وصلت تكاليف التحويل لاكتر من 50$, مطوري عملة ايثيريوم يعولون على ان الاصدار الجديد من العملة سيحل مشاكل ال scalabitiy والوقت وحده سيكون كفيل بتأكيد صحة هدا الكلام من عدمه.

It's done, and it's almost flat with just -0.0858% which doesn't mean anything because that tiny drop could be the affect of luck and not a single miner has left the network, very bad news for those who are counting on either a drop in difficulty or a spike in price, flat price and difficulty works for me, but to many people, this only prolongs their ROI given that most of them think if the price doesn't go up then the difficulty will have to drop which hasn't been the case for quite some time now.

Current diff status:

لاداعي للاعتذار اخوتي , لايوجد وقت محدد, قصدي كان ان ترسول عنواينكم "بعد" الوقت وليس اثنائه.

نظرا لعدم اكتمال العدد ومن الواضح اننا لن نصل الى 10 اعضاء فقررت تغير المبلغ من 0.001 الى 0.0015 اي حوالي 15$ بالسعر الحالي, بهده الطريقة كل شخص اشترك وحتى وان لم يفز يكون تحصل على الاقل مبلغ  معقول بعد خصم رسوم التحويل, طبعا في حال ارسال 0.0015 بتكوين ل Chipmixer سوف يتم اعتبار ال 0.0005 تبرع للمكسر كما اشار الاخ خالد, طبعا انت لست ملزم بعمل هدا ويكفي ارسال المبلغ الاذنى لكي يكتمل معك الشرح العملي.

بالتوفيق.

The forum gives you all the ability to decide the source/sources of feedback you want to see, but most members here have only the "default trust" group in their trust list, so all in all, none-DT members (The vast majority of the forum members) are the once who give the default trust list value and importance. If you have a better way of dealing with the trust system go ahead and propose it, I am pretty sure it won't be as effective as the one we have now even though it's far from perfect, it's probably the best we can have, and until members learn how to use a customized trust list - nothing will change.

Awesome Miner firmware is nothing but a re-branded version of Vnish firmware, so I highly doubt that they can edit the firmware in such a way, in fact, even the "unlock" tool is from Vnish IIRC, with that being said, I was personally able to migrate from Vnish (AowsomeMiner version as well as Asic.to) back to Bitmain and the other way around, this works on S9 as well as T17, I am not sure about the other versions but I can only assume they all are the same.


As far as I know, only Bitmain locks your miner, I have only tried Vnish and BO firmware so I can't speak about the other dozen firmware out there, but I have not heard about any other firmware except for Bitmiain's that would lock the miner, of course, absence of evidence isn't evidence of absence.

في الفترة الاخيرة معظم المنصات قامت باضافة زوج بتكوين-دولار للمضاربة على سعر البتكوين سواء ب long or short , البعض منها ايضا اضاف المضاربة على future contracts, ولكن كما اوضحت انت اخي فهده المضاربة لا تعني انك تملك تلك العملة, يعني لو اشتريت ايوانة صينية بالدولار وكسبت 10% فأن مكسبك سيكون بالعملة ال base وهي في العادة الدولار الامريكي, طبعا هدا نفس الشي ينطبق على منصات الكريبتو عند تداول على future / margin لانهم بعكس ال spot فالمكسب والخسارة يكون بعملة واحدة.

اولا مرحبا بعودتك الى المنتدى اخ Ulven , تانيا لايوجد اي شي يمنع انضمامك للمسابقة فرتبتك تسمح بذلك, تم اضافة اسمك للقائمة واتمنى لك التوفيق.


** ارجو من الاخوة الموجودين في القائمة ارسال عنواين بتكوين غدا الاحد (4-10-2020) بعد الساعة السادسة مساء بتوقيت قرينتش, طبعا هدا لايعني ان باب الانظمام قد اغلق, ولكن الاعضاء الموجودن حاليا لديهم الحق في استغلال الوقت والبداء في تجهيز الشرح وهم ليس مجبرين على انتظار باقي الاعضاء.

In this part of the kernel:


It shows that the miner can't find any chips on all 3 hashboards, and it seems like one of the 3 hashboards is missing because the kernel log only shows 6 chains (1,2,8,9,10,11) when it should show (1,2,3,8,9,10,11,12,13).

The kernel log suggests that your miner is dead, but this also can be a power related issue, what PSU are you using and what is the voltage?

لم الاحظ هدا حتى اطلعت على بروفايل Ulven ومن ثم بروفايل Salamstar وتبين لي ان الحظر فقط حتى نهاية السنة يعني حوالي 90 يوم فقط وهدا امر اكثر من منصف من وجهة نظري لانه جرت العادة ان يكون الحظر لسنوات وليس لاشهر, اتمنى من كل قلبي ان تستتمرو هده الفرصة وتبتعدو عن الاخطاء, نصيحتي لا تحاول حتى الدخول بحسابات اخرى حتى وان كان هدا ليش ضد قوانين المنتدى, ولكن كما يقول المثل " ابعد عن الشر وغنيله".

بالمناسبة مرحبا بعودتكم واتمنى ان تشرفونا في المسابقة الجديدة.

Phill and I ( as well as a few other members) had the same Email last year IIRC, so we are familiar with "Bitmain Balance" thing, there was a whole topic regarding that which I can't seem to find, anyway, you don't have to do anything now, they will ship the miner without a PSU and the PSU's value would be credited to your Bitmain account.

When you wish to use it, all you have to do is select USD Wire (so that your order won't expire in 2 hours), and then send them an email tell them you wish to use your balance to pay for your order ID xxxxxx, and since they have nothing for sale at this moment, then all you can do is make sure the balance shows in your account and leave it there.

When this happened to us last year, they gave us an option to "Withdraw" the balance, it took about 60 days for the BTC to show up, so do ask them if that is an option, if not - just wait until they have something else for sale which you might want to buy.

يعني الخلاصة ان المنصة التي وضعت رابطها في نهاية الموضوع هي منصة موثوقة؟ انا لم اسمع بهده المنصة من قبل وببحث سريع لايبدو انها منصة ينصح باستخدامها, وهده احدا الاسباب https://www.forexpeacearmy.com/forex-reviews/14281/atfx-forex-brokers

لايوجد تعليقات بخصوص كون المنصة "سكام" ولكن يبدو انها سيئة بالمجمل, بما انك وضعت رابطها في الموضوع هل يمكنك ان تشرح لنا عن ميزاتها ولماذا قد يستخدمها اي شخص؟

You are 100% correct on this one, we all have different ways to run our businesses and to each their own goals, mine has always been on the low-risk side, in other words, I always focus on fast ROI, and the only time I did something different I was screwed.

Telling people that I have 300KW to use and they all are S9 seems stupid, some would suggest that since my power is limited but free I should go for more efficient gears.

In order for me not to push things too much, I usually keep the load around 200ish KW, with just about 180 S9s in that farm, what I can alternatively do is use that 200KW for S19 pros for an example, and then I will have about 70 of them that hash at  7700TH instead of just 2500TH, I am sure many people would have gone with S19 pros or T17 at least, but my maths won't work that way, and here is why:

S9i 14th costs about 60$ shipped
S19 pro costs about $3500 shipped

This is $10,800 vs 245,000, in fact, even if I were to go with T17s, the maths will still favour the S9s in every single way.

Also, it isn't just the ROI factor, it is the robustness of these gears, in my other mini-farm since power is pretty limited to about 180amps, I can only use about 28 S9s, which is a bit less than 390TH and isn't worth the trouble, so I went ahead and filled with more efficient gears (a mixture of the 17 series) and now I have a ton of dead boards and PSUs, after having re-done the math, I would have been better of with keeping just S9s in there, but well, a lesson learned.

I plan to close down this mini-farm by next year and expand the other one, I would like to get a 600Kva transformer (won't be easy but doable) and I will only place S9s in there, my initial plan was to get rid of those Antminer 17 series and replace them with MicroBT M21s, but two things got in my way

1- M21s price increased after the 14k bull run and the shutdown of bitmain shop.
2- People here are heavily focused on ROI as well, so nobody is willing to pay $1000 for an S17 pro that does 52th when they can buy about 15*S9s for the same price and mine at 200TH, so I am stuck with these 17 series gears and looks like I am going to milk them until they die on me.
