It's probably not, I know many people in UAE, none of them is hardly named Donny , jokes aside, with all honesty, I believe this is nothing but a scam attempt, I can't tell you how I arrived at this conclusion (for security purposes but being in this mess long enough, I have good reasons to believe that this guy is not legit at all).

With that said, if you are interested in "investing" with him, please don't unless you are in Dubai and have seen the facilities and gears, that will at least reduce your chances of getting scammed.

I tried to use all the imagination I can afford and honestly I can't see how your control board will damage the fans, the miner's fan isn't some sort of a sophisticated piece of electronics where a dozen of things can go wrong with it, it is just a .. fan.  So I still suspect it's the air pressure that causes this increase fan failure, before you fix it, there isn't much you need to troubleshoot, not even the quality of the fans.


Where do you see that on the pool status page or the miner itself? hash variance on the pool is pretty normal, on your miner status page, it's a lot less noticeable, however, seeing 50th and 250th from a mining gear that puts on 95th on average is somehow very strange, I have seen my M20s does 80th instead of 64th, sometimes 55th, but nothing close to 50% or 200% as you explain, it certainly is strange.

The hashrate variance is probably caused by a bug on antpool, maybe the difficulty code isn't right, or maybe some issues with the miner itself, but really, before pointing your gears to a proper pool -- it's hard to tell where the problem could be, so if you want PPS+ pool, try Viabtc (i personally use it), it has a bit higher fees than most other PPS+ pools, but to me, it's worth every satoshi.

My guess is that nothing is going to change for Bitmain and the other mining manufacturers, they might stop accepting crypto payments to comply with the new regulations, but I highly doubt that they will be forced to leave China, the Chinese government only has a problem with crypto and mining, I don't see why would they want to shut down mining gears manufacturers that feed tens of thousands of Chinese.

But if what you think actually ends up happening, it will be good for the difficulty I suppose, the making of these gears anywhere outside of China mainland will without a doubt make them a lot more expensive.

As for burn-in, maybe they can use a bogus Bitcoin address such as "1BitcoinEaterAddressDontSendf59kuE" and they will rest assured that nobody can spend it.

A few hours before the news from China when BTC was at 44k, the pace was positive it was at about 101.5%, right now it's 99% flat, could be "luck doing it's thing" but I am leaning towards the fact that price drives those mining profiles as explained in my previous post.



Used gears prices in China fell by a tiny percentage in the past few weeks, nothing major, I believe this is based on the fact that right after the mining ban prices dipped a lot for a short while due to the increase in supply, and then in a few weeks prices started to rise due to demand, this crazy shift in the ratio of demand-supply ratio made the level of impact of bitcoin price on mining gears a lot less.

Usually, gear prices are determined by profitability,  lower diff / higher bitcoin prices = increase in gear prices, the exact opposite is also true, but recently due to the ban, you will find that gear prices go up with profitability going down or the opposite, so it will take a while for things to settle and go back to normal.

Same here, since (as you are probably already aware) that power rate isn't a problem for me, I only play with those numbers for cooling purposes, but if I had to pay a large bill then making my gears 20-30% more effienct when prices are just not right - will most certainly be something that I do on daily bases (automatically), also add to that the fact that smart mining pools like Viabtc give you the option to convert your payouts to a stable coin automatically, so this combined with the auto-switching becomes a great tool for managing your gears this way.

An S17+ can do 80th at 3160w (40w/th) and it can do 52th at 1700w (32w/th), the effienct profile is 20% more effienct, while the beast mode gives you 50% more hashrate, if we assume that 20-30% of mining gears are switching between similar profiles, then it won't be surprising to see huge immediate shifts in hashrate as the price moves up/down

Can't speak about the other 3 epochs, but for this one, I tend to believe that the 10% price increase had a major effect on this, 2 days ago when the price was at 39k-40k the pace was well before 96 (I believe it was at 91) and then it started rising as the price kept moving up, which means there is a good possibility that many miners are mining at the edge of being profitable.

The other possible scenario which is more likely would be the automated overclocking/underclocking, with all the available tools today, miners can set their miners to mine at say 70w/th when prices is above x, and then drop to 50w/th when the price is below x (the latter will result in a less hash rate), the over/underclocking effect is real, personally, I have just about 15% of my total hashrate setting on the sidelines waiting for mid-October, those will come online with exactly 3 clicks.

For viabtc, the above points are likely less worthy of any consideration, but the point you mentioned here is key


I have noticed and warned about this subject back in November 2020, Viabtc will only allow you to point those contracts to their PPS+ pool, which is more than clear that Viabtc does not really own any mining gears, they will simply collect cash from you and give you bitcoin based on the theoretical income of that imaginary hashrate you pay for, so once the contact starts generating a lot more than what you pay, I don't see what stops Viabtc from rejecting to pay you anything.

Given that they are a well-built company, they won't just scam you, they will probably offer you a refund and maybe some kind of bonus on top and tell you "sorry our mining facilities were shut down by the government" or any other excuse, they could be honest and bear the loses, but I highly doubt that they will pay you a 100$ in BTC in return for say for an example the $20 you pay them, this is just a high risk that I certainly wouldn't want to take under any circumstances.

That is a possibility. however, I have personally used some very cheap fans on my gears and they don't die anywhere close to the rate OP is talking about, this is likely a combination of bad quality and some other issues.

OP, what is the design of your farm? pressure plays a major role when it comes to the lifespan of these fans, I remember before fixing the pressure in the farm we were losing fans a lot more often than we do now, ever since we controlled the air pressure we seldom lose fans despite the fact that we run most of them at a constant speed of 90% where temps are usually a lot hotter than your temps.

Why does anyone else hide their code then? why can't everyone just publish their code and the whole world becomes a nice little happy place? just because they hide the code does not necessarily mean they are doing something bad, they could be doing that so other folks can't use/sell it for free.

OP, none of the "trustworthy" custom firmware have the option you are looking for, it's safer and better for them to just charge you the fees by using your miner to mine to their pool, I don't see why would anyone offer a one time payment which is a lot harder to maintain.

There are a few factors involved, nothing I say or think is worth anything for that matter, in other words, you can't take any of it to the bank, what I know and have been saying for years is that difficulty will ONLY go up regardless of what the price does, of course, I am not talking about the short term drops that happen within a month or so, I am simply stating that the average difficulty this year will without a doubt be less than that of next year.

The second most important factor to most folks would be the price of bitcoin, while price tends to go up in the very long term, there is no guarantee that it will go up within the period of the contract, plus, notice why I said "to most folks" because, to me, price does not matter, simply based on the fact that if you are certain that price will go up, why not just buy bitcoin instead of those mining contracts?


The whole purpose of mining be it cloud mining or actual mining is to make more BTC than what you can buy directly, if not, why even bother? of course, there is always a chance that you will end up making more BTC buying those contracts, but then, so many stars have to be aligned for that to happen, chances are, most folks won't be making more BTC than what they could otherwise buy directly.

The recent difficulty drop caused by the mess in China was probably the only reason why buying those contracts a few months back was a good move, but I won't be counting on that to happen again.

The majority of cloud mining companies are nothing but scam, the rest are overpriced, Viabtc offers a legit cloud mining service, I have not tried it but I use viabtc for mining and they are indeed trusted so it's highly unlikely that such a large pool will turn out to be selling scam mining contracts.

Also, IIRC bitdeer has a partnership with Bitmain which makes them somehow trustworthy, but again, the legit ones are overpriced, the fake ones are just ... fake.

انا لا انصح اي شخص بتحميل هده البرامج فهيا في اسواء الاحوال تكون اداة لاختراق حساباتك والوصول لملفاتك وحاجياتك الشخصية وبيعها لمن يدفع مقابلها سواء شركات الدعاية او غيرها, وفي احسن الاحوال هده البرامج هي مضيعة للوقت وتقوم باستخدام هاتفك في اشياء اخرى عكس التي تصرح به.

هل اجزم انك لن تتحصل علي اي مكسب من مثل هده البرامج؟ بكل تأكيد لا, ولكن هل ستتحصل على مبلغ يبرر الوقت والمخاطرة المرتبطة بتحميل مثل هده البرمجيات؟  على الاغلب لا.

الامر نسبي, مثلا معظم حملات التوقيع في المنتدى تدفع مثل هدا المبلغ وبعضها يدفع هدا المبلغ اسبوعيا, وبضعها يدفع ضعف هدا المبلغ اسبوعيا, يعني ان التركيز على بناء حسابك في المنتدى (وهده واحدة من عدة اشياء اخرى) دخلها افضل بكثير, اعرف ايضا بعض الاصدقاء يجنون مبالغ اكبر من هده بكثير عبر وضع روابط احالة لمنصات في شروحات على اليوتيوب والفيسبوك و غيرها, اعذرني على استخدام مصطلح "مضيعة للوقت" ربما كان الاجدر ان اقول ( هنالك بدائل قد تأتيك بعائد افضل) وعلى العموم اعتذر عن التطرق لهده النقطة من الاساس.

This kernel log looks pretty strange, what firmware version is this?


It's extremely unlikely to get a hold of any trusted firmware that supports S17E, I believe thierry4wd has a modded version for this, I am sure you can't get the chain to work without all chips, but you might bring them to life by changing the voltage or/and frequency, so if the modded version allows that, then you have a good chance.

But overall, you need to be prepared for the worst, the 17 series gears are the worst mining gears anyone has ever produced, the "E" version of the 17 series is the worst among the series, so you are likely to have 50% failure rate in a few months, sorry to bring you even more bad news, but it's what it is, you should start looking for a repair service nearby as all the other chains will likely start failing in the not so distant future.

منطقيا ان كان اصل الشي حرام فما يترتب عليه من كسب فهو محرم ايضا, ولكن الاهم من هدا كله انك تسئل في المكان الخاطيء, لا اعتقد انه يوجد اي شخص هنا مؤهل فقهيا ودينيا لاجابتك على مثل هده الاسئلة فالفتوى في مثل هده الاشياء تطلب دراية وفهم موسع.

اما نصيحتي لك وهي منفصلة عن الجانب الديني هي ان تبحت عن مصادر دخل اخرى فمواضيع البونص بغض النظر عن مصدرها قد يكون مضيعة للوقت.

The miner needs some time to settle, it does not seem like this miner has been online for long enough, leave it online for 4-6 hours and see if that changes anything, also the way you post the logs is so messy, use the code tag when posting anything like that.

Really? the T17 uses 4 fans, by "added" it's clear that he means he replaced an old fan with a new fan not randomly installed a new fan and mounted it in the middle of nowhere.


I agree, I am also against ignoring a critical issue like a lost fan, it's just a recipe for disaster IMO, chances are the fans he installed are bad, the signal wire is missing or he positioned the fan backward, fans need to be blowing air in the SAME direction pointing to the opposite direction of the LAN plug whether they are intake or exhaust.

Well, then why don't they put this warning for other mining gears that use separate PSUs if the purpose is what you claim? I don't know what to believe since I have not tried any of that, but my guess is that the warning isn't a random one, also I just noticed that the tool you are using is not the standard bitmain fixture that folks like Zeusbtc and other sellers on Alibaba sell, you are using the Russian version asic.repair which is a whole different tool, so maybe different tools - different setups.

And then what happens after this line? there is no way the kernel log will stop at this stage, it needs to check the other fan which is usually fan 6 in your case, or at least tell you that one of the fans is lost, not sure why haven't you posted the complete kernel log, nobody can help you if you can't read and understand simple requests.

Are you sure you placed the new fans in the right direction? please post images of the new fans you installed, make sure the plugs are visible, also seeing all fan spin does not mean all of them are actually working, the airflow of 1 fan can move the other which will give you a false signal.
