Will bitmain go bankrupt? I wish so, they have already abused their clients, the mining community and Bitcoin in general, I feel bad for those who have thier money stuck with bitmain and have yet to receive thier mining gears/parts because the two founders of this company can't get thier shit together, but I won't be sad to see them leave the game or slow down for months to come so that their rivals such as Canaan and MicroBt will have a better chance in improving also for other new players to potentially join the market.

It's also worth saying that even if they restock some gears on thier website, people should still be careful as we can't tell who really owns the website now, it does seem like it's under Jihan's control while Zhan still control the warehouses, but we won't know where would the money go to and wether or not you will ever receive a mining gear or your money back with all the mess going on, so please be careful.

which is around 50 to 55 watts.

my point is amps and volts on a meter can be off by 10%

in fact a meter can be adjusted or calibrated so the only thing in question is if the meter is accurate.

That's a good point phill, not sure if they be adjusted but sure they can be off by a good percentage, something like "Kill A Watt" would be much more accurate, with that being said as long as the meter hasn't been tempered with in a way that it would show lower values than the real once and accounting for up to 20% in accuracy to the downside, he is still just about the 60w/th mark which is indeed a lot more effienct than the best reported number so far which is 70w/th.

I will be willing to test the mod as well, let's see what OP has to say.

Not sure why hasn't anybody responded to this video, I watched it and based on the video you got the following:

2 S9 hashboards doing 6.2th and consuming 1.5 amps, in the video you did measure the voltage from the same socket that the S9 uses which was 209-210v so that is pretty much 1.5a*210v = 315w for 6.2th or 50w / th, and there doesn't seem to be a way for you to cheat the video content, so these results are impressive to say the least.

Please post more updates and wether the miner was able to run stable for hours/days with these configurations, would also love to hear thierry4wd's take on this.

على ما يبدو الوضع صعب جداً والسوريون أدرى بهذا الأمر , لم أكن يوماً في صف الوسطاء ولكن في الوقت الحالي أظن بأن الجميع يرى ما يحدث حالياً لذا لا ألوم أي وسيط وخصوصاً اذا قرر التوقف عن العمل
بالنسبة لحوادث النصب فمن الأفضل عدم التعامل مع أي شخص لأنهم بالفعل كثروا كثيراً واستغلوا غياب الأسماء الموثوقة , الأفضل الآن ربما البحث عن طرف آخر والتقابل معه
الحلول دائماً موجودة ولكن الوضع الحالي ليس مناسب على الإطلاق ( أتمنى أن تكون قد وصلت الفكرة )

هل المشكلة في بيع البتكوين والعملات الرقمية ام تداول العملات الاجنبية بصفة عامة؟ ان كانت المشكلة فقط في البتكوين هل من الممكن تجربة وسائل دفع اخرى مثل Skrill , Payeer او غيرها من بنوك الانترنت؟ ايضا هل الحدود مع تركيا مفتوحة للتنقل او على الاقل هل يوجد اموال يتم تحويلها مابين تركيا وسوريا لغرض التجارة مثلا؟ لايجب ان تكون تركيا يمكن ان تكون اي دولة اخرى لديها علاقات "مالية" جيدة مع تركيا ويوجد بها حركة تجارية بحيث ان بعض التجار قد يحتاجو لتحويل اموال الى تلك الدول لشراء البضائع فهنا يمكن ان تكون البتكوين حل لهم لارسال الامول وحل لمن يمتلك البتكوين لبيعها, طبعا هدا يعتمد على حجم البيع والشراء وان كان ملائم, على العموم هدا ارتجال مني في فهم المشكلة ولكن ان كان هناك شرح مفضل اكثر ربما يمكن التعاون لايجاد حلول للاخوة السورين.

would you rather just deal with 20 841 clusters, each cluster being 20 miners with a single IP address and mining info input?

There is a downside to this way of operation, having 400 individual IPs and most importantly workers gives you the ability to keep track of everything from the pool-side, when I look at the pool status using the app on my phone or a "watch link" even from untrusted device, I can tell if there is a problem with any given miner, so i can call my guy and ask him to reboot miner xxx.

Having 20 miners with the same worker will require a local access in order to troubleshoot the bad unit, also as far as setting up a ton of miners it's no longer an issue with so many programs that will handle that for you in no time, so this isn't really an advantage but rather a disadvantage ( a minor one to be reasonable), however, less network cabling / switches is the only advantage in having clusters of 20 miners.

With that being said and without owning any of these avalon gears, based on your words and the other trusted members, I can tell that they are way more robust than the equivalent of bitmain's S9, the only advantage that S9s have over these gears is the ability to downclock them down to 70w/th, not sure of these Avalon gears can do 70w/th but since he has free power his main focus should be on durability and lifespan which without a doubt favours Avalon 841.
3666  Bitcoin / Mining support / Re: t17+ 55 th/s problem on: August 01, 2020, 10:37:52 PM
Yes, thats it, PSU was on the top, i see lot of images in the net that way, the best way is leaving PSU bottom, sad no know this before.

Most people on the internet are clueless, some random person on youtube position their miner in that way and people think it's the best way to do it, you should always refer back to this forum for more information.

Weird part is that i remove a heatsink and i dont see any glue like the S9 serie, i see is soldering, why? i think glue is better and have more resistance.

Are you sure? why would they solder an aluminum on a plastic-like surface? will that even work? maybe they used a tiny amount of black glue which was all stuck on the chip itself and thus it's hard to see, did you confirm that the chip's surface is soft and has no trace of any glue at all?
3667  Bitcoin / Mining software (miners) / Re: Release S17E custom firmware on: August 01, 2020, 10:10:21 PM
Big oooof, 500$ might be a over the top, maybe it's good if you want to sell it to resellers, but it's bad for small miners like me or someone who has only a few of S17e (which can be bought for roughly 900$ nowadays so you get my point).

If it were my firmware I would probably price it at 3% of 1 year of mining, this is based on the fact that 3% is about the average fees for custom firmware, and that 1 years is the average lifetime for these lousy gears.

As of today the S17e makes about $6.48 a day, or $195 a month so that's 0.016 BTC / month so that will be 0.192BTC a year and 3% of that is 0.00576BTC or $68, can be rounded to 70$ per miner.

The price is good for the buyer if their gear manges to stay alive and protifble after 12 months, bad if it fails to reach the 12 months point, it's good for the buyer if the price of bitcoin goes up and vice versa, so it's a sort of a risk to both the buyer/seller but I believe it's reasonable on average.

I could probably come up with some good arguments on why it should be cheaper and at the same time there are plenty of arguments on why it should be more expensive, but overall I believe this is a fair price.
3668  Bitcoin / Mining support / Re: S15 doesn't power on on: August 01, 2020, 09:57:13 PM
I bought a 2560 off mouser for $8 shipped. I'll post an update when I get it installed if that fixes it or not.

And I don't take it as a mislabeled website or anything with Zeus BTC either because I talked to him and I was told several times that the 2560 they sell is 1000v and they do not sell any 2510 chips.

$8 is pretty reasonable compared to $40 at least, as far as the the support guy/girl institing that the 2560 bridge rectifier is able to handle 1000v it is pretty much b.s, I think whoever you were talking to doesn't understand much and they were simply counting on the label on the website, the owner of the website "kevin" surely knows well enough about electronics, he makes most of the youtube videos regarding "fixing miners" and I believe he is the head of the team that makes the "fixture tools" for all the antminer models, so I will make sure to deliver a message/complaint to him to re-label the product and educate his support team.

Anyway, keep us updated.

You can literally turn the miner upside down so that the chips are on top, there is nothing that could restrict you from doing so, simply place the PSU at the bottom like so:



Sorry about the quality of the image, but I guess you should clearly see that in this position all the chips are facing up and without you flipping the miner to another position the large heatsinks can never touch the smaller once.

What you did was placing the miner with the PSU facing up, so either the 3rd or middle board (most likely middle) had a headsink which fell on the 1st board' small heatsinks.
3671  Local / العربية (Arabic) / Re: معاملات وخدمات برسوم صفرية؟؟!! on: July 31, 2020, 11:36:59 PM
هل يمكن لاي شخص سرد قائمة بالمنصات التي تتعامل "برسوم صفرية"؟ لم اسمع بهدا الشي ولا اعتقد انه ممكن اصلا, بعض الخدمات مثل Shapeshift تتيح لك مقايضة عملة بعملة اخرى على اساس انها مجانا ولكن المكسب لديهم يكون في تسعير العملات, فلو قمت بتحويل BTC to USD وكان السعر بالمتوسط في المنصات 10,000$ سيحسبون لك ان السعر 9950$ مثلا, ولكن كل هده مصطلحات دعائية اما الواقع فهو عكس ذلك تماما, ادارة وتشغيل منصة تداول للعملات تكلف الكثير من المال, بحكم مجال دراستي وعملي يمكنن الجزم بأن المنصات الكبيرة تدفع مالا يقل عن عشرات الاف الدولارات فقط لتشغيل السيرفرات الخاصة بها, كمية التداول وكل امر بيع وشراء يحتاج الى استخدام صف كامل بعدد كبير من الاعمدة في قاعدة البيانات, معالجة وتخزين هده الارقام مكلف جدا جدا جدا لدرجة انه من شبه المستحيل ان يحققو دخل من اي شي اخر مثال الدعاية او حتى بيع المعلومات ويجب ان يكون هناك رسوم على كل عملية.

يمكن لبعض المنصات ان تقدم فترات معينة من التداول المجاني كنوع من التداول ولكن مهما كان رأس مال المصنة فمثل هده الامور لاتستمر طويلا, مثلا Binance عندما اطلقت حوض التعدين اتاحت التعدين بالمجان لمدة شهر بدون رسوم بنظام FPPS والذي في العادة يكون 4% , والان الرسوم هي 2.5% , نظريا تمكنت باينانس من تعدين حاولي 522 بتكوين يوميا لمدة شهر في وقت كانت قيمة البتكوين حوالي 9000$, مما يعني انهم خلال ذلك الشهر قامو بتععدين 16560 بتكوين يعني ان 2.5% تعادل 414 بتكوين او 3,726,000$ , نظريا ايضا ال 2.5% لاتمتل مكسب صافي لباينانس (موضوع يطول شرحه) وتقريبيا المكسب هو النصف يعني بالملخص بايناس قامت بدفع اكثر من مليون ونصف دولار خلال شهر لاستقطاب قوة تعدين للحوض ونجحت في ذلك وهي الان تمتلك مايقارب 8-9% من اجمالي قوة التعدين مما يعني انهم خلال الشهر التاني قامو باسترداد مبلغ مليون ونص دولار الذي خسروه وهم الان يجنون نفس المبلغ تقريبا شهريا!.

Sorry for your loss, fortunately it didn't catch fire or something, did one of the heatsinks from the top board fall on the lower board and caused short circuit? I don't seem to understand what happened exactly looking at the images alone, my initial guess is that the vertical positioning of the miner wouldn't prevent such issues, assuming a heatsink from board A caused board B/C to short, in fact, that "horizontal position" is safer in such cases because even if the heatsink is losen, it will stay where it is assuming the chips are facing upward because the smaller heatsinks on the other side of the hashbaord don't tend to fall.

Anyway I would love to know what happened exactly.
3673  Bitcoin / Mining support / Re: S15 doesn't power on on: July 31, 2020, 09:37:57 PM
Sadly I can't vouch for the accuracy of the information on thier website regarding this product, it is simply something beyond my ablitity, for what we know it could be mislabeled, but I know that if they tell you it will work on APW8, it will most likely will, but $40 is way too much IMO, i mean there is no guarntee that this will be the only problem and that the PSU will work again, so investing $40 in that is something I wouldn't do, how much does the 600v on mouser go for? also why don't you get the 1000v?
3674  Bitcoin / Mining support / Re: These sites are safe for overclocking T17 , S17 ? on: July 30, 2020, 11:12:14 PM
Probably not, I have never heart of them, aside from thierry4wd "hacked" versions of some of the original bitmain firmware or Vnish (Asic.to / Awoesmeminer there isn't another firmware that's widely known around the mining community in this forum at least.

In addition, why on earth do you want to overclock your T17/S17 gears? a while ago I replied to your thread complaining about losing a hashboard on your T17+, all of these 17 series gears have terrible solder/adhesive and overclocking them will only speed up the process of toasting those hashboards, if anything you should be looking for underclocking rather than overclocking, but hey, your gears - your call.
3675  Bitcoin / Mining support / Re: t17+ 55 th/s problem on: July 30, 2020, 10:54:02 PM
Thanks mikeywith, I changed fan speed to 90% with your method. but problem is stable yet.

Changing the fan speed fixes the high temps on the other boards, it isn't going to fix the bad board, does your miner report lower temps on the two working chains? it MUST, and that should "prevent" the other two working boards from falling apart.

I heard form some technician that we must set it With a 90 degree deviation horizontally instead of the normal position of miner in surface for problem heatsink in T17 and S17 !! whats your idea?

The_binary_Observer mentioned about this before, and my reply to him was:

Quote
... without totally negating the effect of positioning the miner in a horizontal position, it's safe to assume that unless you can do it easily [1] it's really not worth the effort, there isn't much you can do about these heatsinks until they fall, sadly.

[1]- if you use spilt-room design as I do and you have already made a whole to fit the miner vertically, going horizontal is a lot of effort, which IMO not worth it given the little advantages you get from this, but if it's a matter of simply repositioning the miner in 30-60 seconds, go ahead, you lose nothing...

If you want to go ahead with the "horizontal position" make sure the large heatsinks are facing the top, you must understand that the PCB is covered by 2 layers of heatsinks, one sits right on the top of the chip (they are lager in size and they are the once that tend to fall 99.99% of the time), if you would mistakenly position them in the wrong directing (facing down) you could expose them to more gravity and they might fall even faster.

In general you want to these gears to run as cool as possible so that the lousy solder paste doesn't get heated, so having your fans at 90-100% is without a doubt more effective than re-positioning the miner.
3676  Bitcoin / Mining support / Re: S15 doesn't power on on: July 30, 2020, 09:07:44 PM
I have identified that the bridge rectifier is bad. And I am working on pulling it out but I'm looking on mouser and Google to find a new one but I'm not sure on the specs. It reads that it's 2506 but there is like 50 and they all look similar and have slightly different specs. Which one do I need?

You probably need  "GBJ2506 power rectifier 1000v 25A", that looks like this one



This will 99% work for you, I have yet to touch one but I know that https://www.zeusbtc.com only sell spare parts that work for mining gears, and they have this product https://www.zeusbtc.com/RepairDetails.asp?ID=101 and it matches the 2506 you got on yours.

Having said that and to be 100% sure, I suggest you talk to kevin or whoever is in charge, simply contact their support and ask if this would work on your APW8 or whichever PSU you are trying to fix, those guys know their stuff very well so I would trust whatever they got to tell you.

I want sell this, by miner, without any devfee, one purchasse, no futur fee (mine 100% at your pool), and containe no malware of corse, is original firmware patched Wink

First of all allow me to congratulate on your new firmware, I have a few questions regarding how are you planning to distribute the firmware, in other words how do you ensure that other people won't re-sell it, I understand that trusted people of the community like your first client Favebook won't be doing that, but what about others?

Also the price tag should be discussed in public IMO, pricing is very difficulty and it's almost impossible to get the perfect number that would work well for you and the clients, so perhabs a community discussion on the subject will be very helpful, of course you could ignore my suggestion and keep the sales private, I just  think it would sell out a lot better when price is known and the community "agrees" to it.

Your miner has a total of 12 temp sensors, so that is 4 on each board, now it simply can't communicate with any of the 4 sensors on the 3rd board (usually most left), but based on information I have collected and confirmed from different sources including my own and other memmber's experince, it's unlikely that all 4 sensors went bad, and it's more likely than not that one of the chips/heatsinks lost conductivity to the PCB and it causes this error, there are a few things you can try, chances are slim but there is always hope.

It is easy to calculate the block rewards because it is static (6.25 btc/block), the rest comes from the transaction fees which varies greatly and there is no way to figure out future blocks rewards, you could do something like taking the average block fees for the past month/year and get the average in %, if block fees are 10% then simply multiply your number by 1.1, but again all of these are rough estimations as long as you can't predict the future accurately.
