حسنا أخي مايكي سأخذ الوقت الكافي لقراءة المواضيع و تقييمها و بعدها التصويت للموضوع الأفضل و أتمنى من الله أن يوفقني و لا أظلم أحد في الحقيقة لا أحب أن أسبب الإزعاج للمشاركين على ما يبدو الإدلال بالتصويت يكاد أمرا صعبا نوعا ما.

لا اعتقد انك ستبب ازعاج لاي احد, بالعكس ستكون قد قدمت خدمة لهم ودفعهم نحو تطوير انفسهم في كتابة الموضوع, الغرض من هده المسابقة هوا التعلم وليس الربح, وعلى الاغلب سأقوم بارسال مكافئة مالية بسيطة لكل الذين شاركو حتى الذين لم يفوزو, لذلك لن يخرج احد خسران من المسابقة, في الواقع الخبرة التي اكتسبها الاعضاء في مجال التعدين عبر البحث لكتابة مواضيعهم هي من وجهة نظري اكبر مكسب لهم وكذلك للاعضاء الاخرين.

Hum ... your kernel log is very strange for me... i thinks used by custom firmware... is true ?

As far as I know, there is no custom firmware for S9k yet,I believe vnish should have theirs ready in a few weeks.

if not try for a 40% refund and be willing to settle for a 33% refund.

At 33% it means he bought only 3 hashbaords without a PSU, Control Board, Frame, 4 fans, etc. I think the best he could hope for is 25% assuming every hash board makes 25% (75% in total) and the rest of the components make the remaining 25%.

If the seller is honest and nice enough, they would give them more than that considering the downtime and the efforts in troubleshooting, but I don't see that happening because if the seller was honest they would have tested the machine before sending it out.

وأين سيكون التصويت في الموضوع الخاص بالعضو أم هنا في هذا الموضوع.
أرجو توضيح هذه الأمور وكل الشكر لك

التصويت للموضوع التي تراه الافضل من حسب وجهة نظرك اخي, اما عن كيفية التصويت فيتم التصويت هنا, مثل مافعل الاخ Ya3rob بتصويته هدا

لا اخي يكفي فقط ان تكون لذيك رتبه Member او اكثر للتصويت

سأشارك إن شاء الله في التصويت إذا كان مقبولا

تصويتك مقبول بكل تأكيد اخي فعضويتك تسمح.


المواضيع جيدة ولكن القاسم المشترك في جميعها هو عدم الدقة في الترتيب وطرح المعلومة لذلك اعتقد ان علينا ان ننشئ موضوع لتعليم الاشخاص اساسيات التنسيق بهذا المنتدي وكيف تحول الموضوع والكتابة لشكل جذاب" اعتقد ان لدي موضوع بهذا الشأن بالعام 2017 ولكن الموضوع نفسه يحتاج الي اعادة صياغة ليكون حسنا."

اوفقك الرأي اخي, ترتيب المواضيع هي مشكلة يعاني منها معظم اعضاء المنتدى سواء العرب او الاجانب, وانا شخصيا اعتبر مستواي في التسنيق اقل من جيد واحاول تطوير نفسي بالرغم من انه في هده المرحلة من العمر تصبح مثل هده الاشياء صعبة نوعا ما.

1 - no control over the fans, at least not from the UI

Bitmain are doing a great job limiting the things you can do with your miner, but anyway I have figured out an easy way to temper with fan speed in S9k from the GUI, you can read about here

Quote
2 - ventilation is more then good, tried it also at different ambient temperatures but makes no sense to turn off the other machines, its not just 1-2 of them Grin

Depending on the room size, 1-2 miners can make the place very hot, but since you know the ventilation is "more than good" then there is no need to go the route.

did you inspect the gears for physical damage such as lose heatsinks?
4726  Bitcoin / Mining speculation / Re: Antminer S9 classification on: February 21, 2020, 04:00:13 AM
Maybe the k are all the left over low yield chips that Bitmain wants to get rid from their inventories before ceasing S9 sales?

The K version uses BM1393 and BM1393B chips, S9/S9i use BM1387 and BM1387B and S9j uses BM1387BE, I am not sure if these "models" indicate different chips from TSMC itself or Bitmain adds something more to them after receiving them from TSMC, in other words, not sure if these are the worst chips Bitmain has or TSMC sold, this is due to the lack of my understanding on how these chips are actually used by bitmain.

Having said that, you are probably right, and it does not matter how did these chips came into existence, they are simply the worst once out there. I keep losing a board every now and then, to the point where I stopped bothering, these S9ks run alongside with old S9js/S9s that have been mining for years without any major issues, I think the Chinese know something we don't about the K version, by looking at the price tag in the retail market in China, a used S9j goes for almost the exact price as a brand new S9k.

First of all, always code the kernel log by using the hash/number sign in the toolbar.

Code:
[2020/02/20 23:21:35] ERROR: driver-btm-s17.c:1189 chain[1] - Failed to detect ASIC chips

The error is quite clear, the board is bad, sadly!

To break it down, there is at least a 90% chance that this board is dead and will no longer function, however very seldom there might be other reasons for the kernel to through this error.

A faulty PSU or a bad connection to the control board, you need to first check the ribbon cable that goes from the control board to hash board number 1, it might be loose, however, the best practice would be swapping the cable with a working one, ribbon to board 2 goes to board 1, and vice versa, and the same thing with the PSU, you need to switch the hash board positions.

Expected results:

1-The miner now finds 48 chips on chain 1 and 0 on chips on chain 2 (The hash board is dead)
2-The miner now finds 0 chips on  chain 2 and 48 chips on chain 1   (Ribbon cable/Psu connection is faulty)

very seldom this error might come from a bad firmware, a hard reset might (chances are slim) fix your issue, you should also post the complete kernel log so we know if the other boards work fine. If all boards are bad then this could be a control board related issue.

Meanwhile, you should start contacting whoever you bought it from, let them know what's wrong and that you are going to troubleshoot it using the methods I explained, if the return of product is an option, you should go for it as soon as possible.

تتمتع S20s الآن بمعالج آمن مخصص فقط لحماية كلمة المرور والنمط ورمز PIN ومفتاح البلوكشين الخاص.

هدا تطبيق لفكرة ال hardware wallets حيث ان المفتاح الخاص لايغادر المعالج الخاص بحفظ بيانات المحفظة, كل مايقوم المعالج بعمله هوا توقيع التحويل عند اعطائه ال pin الصحيح, وهده ميزة رائعة جدا بحيث انه حتى وان كان هاتفك يحتوي على برامج تسعى لسرقة اموالك او ان هناك ثغرة في نظام اندرويد نفسه سيكون من الصعب جدا جدا سرقة اموالك من المحفظة.

المشكلة ان الكثير من الناس وانا اولهم لن اقوم باستخدام الهاتف كمحفظة باردة او hardware wallet لان الهاتف معرض للضياع والسرقة و و , ولكن يمكن استخدامه ك hot wallet حيث تكون الحماية فيه اكثر من استخدام المحافظ التقليدية الموجودة على الموبايلات.

هدا الهاتف سيتم اطلاقه يوم 6 من الشهر القادم, السعر والمواصفات الاخرى ستكون الفيصل في تحديد كون انه يستحق الشراء ام لا.

Not sure WTF is happening in China but this articles says Apple to lose billions in sales
https://www.msn.com/en-us/news/technology/coronavirus-could-cost-apple-billions-in-missed-sales-analysts-say/ar-BB108y24

I think the main reason Apple will lose money because of the decrease in demand for its products rather than the production itself, China is a major market and once they stop buying, Apple's value drops, look at crude oil prices, they dropped from $68 to $52 in no time, simply because China is the largest buyer for Crude oil, Apple's revenue in China was about 45 billion dollars last year alone, that's a big hit for them.

As far as mining is concerned, I don't know about other companies, but Bitmain seems to be operating normally, I get replies to my emails normally, they shipped the s17+ control board faster than I thought, the slow in production and the long waiting periods might have been caused by the virus, but it has been this way since the last year-end, maybe not as bad as today, but most certainly nothing too strange.

Bitmain should ship S17+ and T17+ next month, let's see how they do.

على حد علمي هذه الخاصية لا تعمل مع العملات البديلة

في الواقع تقريبا 99% من كلامي في هدا المنتدى مخصص للبتكوين واحيانا انسى اصلا ان هناك عملات اخرى  Shocked.

على العموم الموضوع يعتمد على تصميم العملة, فمثلا عملة ايثيريوم لا تقوم بتحويل القيمة بناء على UXTOs بحيث انه لا يمكنك انشاء عنوان جديد لكل عملية.

مايحدث بطريقة مبسطة هوا الاتي:

لديك 1 بتكوين في عنوانك tttt وتريد ارسال 0.5 بتكوين لصديقك على عنوانه ffff تقوم المحفظة بانشاء عنوان جديد nnnn وفي نفس ال transaction تقوم بارسال 0.5 بتكوين ل ffff و 0.5 لعنوانك الجديد nnnn , مما يعني انه بمجرد ان يصبح المفتاح العام لعنوانك tttt معروف, يكون رصيده قد اصبح 0, في الواقع هدا ليس "قرار" لان المحفظة مجبرة على ارسال ماهو موجود في tttt ولكن بدلا من ترسله 0.5 الى ffff والنص التاني الى tttt (نفس العنوان) تقوم بارساله الى العنوان الجديد nnnn ( الشرح يطول ولكن يكفي فهم النقطة كما هي).

انا لا اعرف ان كانت محافظ الاثيريوم لديها بدائل لحل هده المشكلة , ولكن اعتقد ان الحل بسيط, بدلا من وجود Transaction واحد يمكن ان تتم العملية على التوالي بحيث تقوم بارسال المبلغ الى عنوان المستلم, وبعدها تقوم باجراء تحويل تاني منفصل لعنوان اخر, سيكون هناك فرق زمني في الارسال يمكن استغالاله لسرقة ماهو متبقي من في العنوان الاول, ولكن لا يمكنني التفكير في اي طريقة اخرى, ولكن انا شخص هاوي وافكاري محدودة وبكل تأكيد ان تلك العملات لديها البدائل والحلول, الموضوع يحتاج لبحث اكثر وبصراحة انا لست مهتما كتيرا بالعملات البديلة.
4736  Bitcoin / Mining support / Re: S17 Pro Firmware Booster on: February 19, 2020, 09:47:32 PM
Last I checked awesomeminer is also a vnish re-brand. At least the S9 version they advertised was.

You are right about this one, in fact, Patric from awesome miner himself confirmed that

Quote
Of the 2% mining fee we are actually getting half of it. So we do benefit from customers that go for the Awesome Miner firmware. This is also the reason why we can provide product support for it and also integrate it well with Awesome Miner. Users of other Vnish firmware do get most of the features as well, so your point is valid that we do give away features to a larger user base. Some features like setting Mining Profiles via Awesome Miner is exclusive to our brand of the firmware. We could make more feature exclusive, but we are also trying to be nice to our customers and respect what decisions they make.

The dev fees on Vnish website are as follows

Quote
Dev fee 1.6-1.9% only for S9/T9,  2.6- 2.9% for S17/T17

awesomeminer's fees for S9 is 2% or 3% (without consuming awesomeminer license), for S17/T17 the fee is 3%, so that's anywhere from 0.1% to 0.4% more for awesomeminer, if you use awesomeminer to monitor say, 100 miners, then you have to pay 700$ for the software, so one should do the math and see if the difference in fees is worth the license and the features that awesomeminer provide which Vnish doesn't. If it makes no economic sense, one might want to stick to Vnish, I personally use awesomeminer and I count on it big time to manage my gears, so I wouldn't mind paying a little extra, but that is just me, everyone should run the numbers.
4737  Alternate cryptocurrencies / Mining (Altcoins) / Re: Please Identify this miner for me on: February 19, 2020, 09:01:11 PM
Phill, I have to agree to PassThePopcorn on this one, this without a doubt is Innosilicon Equihash A9++ ZMaster.

Pay attention to the images below for comparsion.

a9++



S9 Dual



There are a few difference in the way they look, but the most obvious one is the white sticker with the blue writing right next to the ethernet port, bitmain always use a sticker with a black background and white writing, only Inno uses white and blue.

What is strange about the image that tmfp posted is in fact Jay Locke's image with his face hidden, Jay Locke is the founder of what's accused of being a Ponzi/MLM, called "goldmine369" and it's also based in UK!



I have no further information neither have I dug any deeper, but there is what looks like a solid scam accusation against the guy in the picture, you can read further here and here.

This is nothing but a warning to tmfp to rethink his choices, I am not accusing goldmine369/Jay Locke for anything without having a rock solid proof.



The math:

A9++ Zmaster is an Equihash based miner, it does not mine bitcoin, so you should not worry about bitcoin halving, the gear makes about 6$ a day after power at 10 cents Kwh , but keep in mind that is somehow a fresh alogthirm, the improvemt of the coming gears will differently kill the current once, it's nothing like Sha256 miners where we at 7nm already, and improvements are very little.

I wouldn't advice anyone to buy these gears, but that's just me!
4738  Bitcoin / Mining support / Re: S17 Pro Firmware Booster on: February 19, 2020, 08:12:30 PM
There are probably a dozen out there, the only two that I would trust would be taserz aka Asic.to's firmware and awesomeminer firmware.

Could there be any better than those two? well maybe, but the amount of fake and scam firmware we see every day stop me from vouching for any firmware which I have not tried/trust the developers behind it.

Having said that, you should always be careful when attempting to overclock/boost your miner, you could easily toast it, stick to "auto-tuning" and/or refer to other user's outputs and what voltage and frequency they suggest.

شكرا لك اخي ميكي على الشرح المميز وعلى مشاركة هذه التجربة معنا

القيم المتاحة هي : 5$,10$,25$,50$
أعتقد أن سعرها ليس غالي والجميل فيها أن تقبل الدفع بالبيتكوين
يعني البطاقة التي سعرها 5$ تعادل حوالي 0.0005$ وهو مبلغ بسيط

اريد توضيح نقطة اخرى وهي ان قيمة البطاقة اقل بقليل من المبلغ الذي يتم دفعه، فمثلا بطاقة 50$ تدفع 52.23$ لتحصل عليها.

مما يعني ان عمولة الموقع اكثر من 4% فيجب تجنب استخدامها الا عند الحاجة، والافضل هوا شراء ال gift cards للمواقع التي تتعامل بها لان سعرها اقل ، يعني مثلا amazon gift يمكن الحصول عليها بدفع 80-90% من قيمتها فقط.

China is really coughing to death and I don't see anything going to hell!

How? with 2,000 deaths of coronavirus? more than that die from car accidents every month in the U.S alone, but even with that "$34 billion were wiped out of apple alone", oil prices feel from $68 to $52 as china imports the most crude oil in the world, everything has been affected by the small and silent half cough of china, china is a "global supply chain", look around your house and you will see china in every corner, if the virus is not contained and cured soon enough, things will get pretty ugly all over the globe.

Let me break this down for you:
GDP PPP per capita:

GDP per capita is not the same as GDP (PPP), you seem to have gotten things mixed up a bit, the example you used is PPP per capita which is pretty dependant on the population size, that's why you see Qatar is placed first but 51th in GDP (PPP). you should probably browse this website http://statisticstimes.com/index.php to get a better understanding of the differences, although this is really going off-topic.

First, how do you get that 4,285,714 s9?
Money!

And this is when economic strat to play their role, bitmain doesn't have that many chips and they need to also put an order on TSMC for that and if TSMC is busy, could it still be done? If its this huge order and must be done quickly just how much not are only prices going to spike, not even mentioning bribing a lot of guys to keep quiet?

The king can have 10 countries and 1000 companies work for him to collect all the miners he needs, money buys everything, he can even buy mining farms in China or any other place.

Could this be done in secrecy? No way!
So until you manage to manufacture that many miners build the infrastructure, ship and install them there is a lot of time to take some measures, and code is pretty faster than a cargo ship.


There is no need to keep this a secret, the King's country can simply say they are going to support bitcoin mining by holding a large mining farm if people find out, a dozen of mining gears get moved around, does anyone know where did the last million S9s go to and who bought them?? anyone who has both power and money can potentially and easily accumulate all the hashrate they need, in fact, the Chinese president now does "technically" have control over all the mining farms in China and can perform the attack if he wants, but you are suggesting that he probably wouldn't, therefore there is no risk?

And anyway, there is nothing we could really do if someone is bent on spending billions or tens of billions attacking it!

There must be, it's to be or not to be, in 2041 BTC has to be worth nearly half a million dollars  for the chain to be as secured against 51% as is today, if it's worth only 100k then it will be 80% less secure than it is now.

I do believe in the role of economy, more people and businesses owning bitcoin gives it more value and more security as whoever uses it should at some point "invest" a portion of what they have to secure the network, I don't discard that role, but there is nothing wrong with planning for a technical-based solution rather than completely counting on the assumption that "nobody will perform a 51% because it's expensive or difficult".
