Or they have long-term contracts with their repair employees and they want to make sure they get them working 10 hours a day for the remaining span of the contract lol.

Alas, Bitmain and their never-ending drama, make the same miner with 4-5 different control boards, change the PSU style for every slight change to the same miner they make, and use $2 solder on a gear you sell for $4,000, just the typical Bitmain.



I learned my lesson after losing a lot of money on the 17 series, I am no longer willing to risk anything with Bitmain, for all I know, they could start shipping the other models that had the large bolt-on heatsink with the stupid single soldered heatsink the movement they run out of those large heatsinks, since I can't verify how my batch is going to look like, I rather not touch anything Bitmain related as long as there are other more reliable options.

If this isn't about BTC then what is?


I too want to move value for free, but have you considered the possibility that there are more people who want to move memes that essentially also have value and are willing to pay more than us? I am sure someone else who had to pay more to acquire some stupid NFT was complaining about my $5 transaction and thinks it's spam, it's hard to get everyone to agree on what is spam and what is not, as far as capitalism style free-market is concerned, those NFTs freaks are transacting value similar to what we do.


True, in fact, none of them even look pretty, I wouldn't pay 10$ for the whole NFT market combined, but I respect the fact that that stupid stuff mean a lot to someone else who is willing to pay for them.

Both links are not working for me, I get this error.


But I get the idea, I don't think it will do you any good, in fact, it could have a negative impact as those walls could trap the heat there and cause the miner to overheat, I'd say just make enough space between them, even better to space them with other low-power gears like your L3s, keep them clean and they will run just fine, I ran these monsters in 45c amp temp at my previous small farm which had terrible cooling, and they are still running, these are not the average Bitmain gears that would break easily.

Not saying you should toast them, but I see nothing wrong with the current temps.
                  

I explained what causes the majority of issues on those Antminer 17 series in the previous post, now check that against the points you listed, and you will see that most of them will not solve the issue and will be a waste of both time and money.

Point 1 is good for anything you buy used, point 6 is good for dead hashboards as per your own experience, and point 7 is only needed when an error that matches eeprom shows up, otherwise, it would be a waste of time.

Now if I have to give you a better tip than all, it would be "do NOT buy any 17 series at all", Now if you are willing to invest time and money to learn how to fix those boards, go for it, you buy cheap broken 17 series for the $100  range, fix them, then either use or resell them, but if you are like me and "can't fix shit", the best thing would be to steer clear from that model.

Actually, temps are not bad at all; fans are running at 5k rpm, which is not 100% since that is 7k rpm; the max temp for the hashboard is 80 c, which you are still 10 degrees away from; so unless the outside temperature increases by another 5-7 c, I do not see a problem.

One thing to know about whatsminer vs. other miners is that the miner's case is designed to get rid of heat, think of it as a large heatsink. You will notice they are hot to touch from the outside, unlike most other gears, so they cannot be stacked too close to one another. I prefer to keep 5 cm of space between them to allow the chasis to get rid of the heat easier.

Actually, judging by the Envtemp of the four miners, you can guess which two are located in the middle.

The pace seems to have slowed down a tiny bit compared to what you posted yesterday.


With just a bit over a day left for this epoch to finish, it's very likely to end up with a small negative adjustment, maybe not enough to wipe out the previous 1.7% jump but pretty close, meanwhile, the price is at 28.5k, the good/bad thing (depends on how you look at it) is that fees have been incredibly high for the last blocks, I saw 1.8 BTC fee block earlier, many blocks were above 1BTC in fees, I think the average for the past 24 hours is pretty close 1BTC per block.

How did you get those figures?

9 BTC in today's price is roughly $261,000

Here is a list of some gear prices for (only for bulk)

M30s++ 100th = $1250 , 10ph = $125,000 or 4.3 BTC

S19 90th = $750 , 10ph = $85,000 or 2.8 BTC

S19 XP 140T = $3400, 10ph = $240,000 or 8.27  BTC

M50s 128th= 2,624, 10ph = 205,000 or 7 BTC.

---

As you see, it could be anywhere between 4.3 BTC to 8.27BTC, of course, this doesn't take into account the other expences which could easily add up 20-30% to each model.

Now let's review the 5 BTC you assumed they would make.

10PH today makes 0.0262, so without any difficulty increase, in the roughly remaining 340 days for the halving they should make almost 9 BTC.

Now you need to account for power bills, someone with S19xp and 6 cents per kWh which seems to be the average would be paying 35% of that 9BTC for bills, someone with M30s would be paying close to 50% of that BTC in power bills.

So the XP guy makes 5.85 before halving (70% into ROI on paper), while the M30s guy makes 4.5 (already hit ROI on paper) BTC before the halving.

What happens after the halving is unknown, it's safe to assume a 50% drop in BTC reward if the price goes up i.e, no hashrate drop from the less efficient miners.

Keep in mind that those figures in the previous line are just ROI on paper, it assumes difficulty won't rise for 340 days, no gear fails, no downtime, no monthly/daily expenses, wiring, networking, and everything is not taken into account, which you honestly can't, because to set up 10ph with S19 XP 0.25MW, it could cost anywhere between a few thousand dollars to a few hundred thousand, depending on where you live, so it's impossible to know for sure that exact cost for 10PH for everyone.

Yours are the "S" model, the "S" after any Whatsminer model represents a more effienct and usually more hashrate gear than the non-S, and then they have the "+, the more of it the more efficient, so any S++ model is better than S and better than S+ and so on.

tho are you sure yours has a +? That model is super rare, it has not been listed on their official distributes for months, which suggests that they made a very limited quantity of it, the currently available models are just the M50s and the M50, with efficiency ranging between 25w/th to 29w/th, and hashrate that goes from 108th to 130th +-5%.

The difference in price, however, is very unreasonable IMO, for example, it's 6$ difference between the 28w and the 25w versions, not sure if that is worth it for a power rate that's below 10c per kWh.

This isn't very accurate, most "powerful computers" are not suitable for BTC mining, mining needs DEDICATED chips that do NOTHING but hash sha256, which is why they are called (application-specific integrated circuit miners), in fact, you could argue that those ASIC miners are not powerful computers by any means given that you have not defined what "computing" actually is, your smartphone is likely more powerful in general computing than the most recent miner in the market.


The only reason why CPUs and GPUs can no longer mine Bitcoin is due to the increase in difficulty and not the increase of miners as people, the concept of miners competing against each other has been there from the get-go, however, the term "compete against each other" is somehow misleading, because they are not, miners compete against block target/difficulty, a hash with a nonce that's lucky enough to solve a block, even when there was only a Satoshi mining BTC he had to compete against difficulty to solve blocks if it's just competing against "others" then satoshi would have mined the 21m bitcoin's in no time.

Furthermore, if everyone stops mining today and they leave just one miner, it doesn't mean he will the blocks which were supposed to the rest of the miners, the single miner will only get the blocks that he would have gotten with nobody leaving the network, of course, since he will need a very long time to finish the epoch, the difficulty will start to slowly adjust until him alone can mine a block every 10 mins, but that will only be possible because difficulty dropped not because "competitors" left.



fast yes, exact, nop, ASICs produce fast-random-hashes and that's all about it.

المنطق وراء هدا الاعتقاد ان افلاس البنوك يعني ان اصحاب الاموال سواء الاغنياء او الفقراء لا يثقون في وضع اموالهم في البنوك مجددا, مما يعني انهم سوف يبحثون عن بديل او حل اخر, احد تلك الحلول هي البتكوين والكريبتو عامة, اضافة الى الذهب والفضة وغيرها من الاشياء التي اتبثت عبر الزمن انها تحتفظ بقيمتها على المدى البعيد.

من وجهة نظري ان هده النظرية يتخللها الكثير من "المنطق", ولكن وسائل الاعلام ومواقع الاخبار تقوم بتضخيم كل شي ومحاولة تسريع الاشياء حيث انها تعطيك انطباع على ان كل البنوك سوف تنهار الشهر المقبل وكل الناس سوف يركضون لسحب اموالهم وشراء بتكوين, ولكن هدا غير صحيح, فهده الاشياء تستغرق سنوات للحدوث, في الواقع هي تحدث منذ سنوات والا مالذي اعطا قيمة بالبتكوين ان كان الاستتمار في البنوك امن وجميع الناس تعتقد ان اموالها وقيمة اموالها لن تتغير؟

من الواضح ان الكثير من الناس لاتتق في البنوك فتقوم بشراء الذهب والبتكوين وغيرها, وكل فترة تزيد كمية تلك الامول التي يتم ضخها في هده العملات والسلع نظرا لان المزيد من الناس تفقد ثقتها في المصارف, طبعا الازمات المصرفية تساهم في الاسراع قليلا في نقل الاموال الى الكريبتو ولكن هدا لايعني ان تحدث في يوم وليلة بل يجب ان يستمر الاجراء لعقود.

Does the control board has an SDcard slot? if so, go to INNO's website and download the Sdcard files to try and flash the control board, I really see no point in unplugging everything when the control board isn't accessible on the network, if this isn't a PSU issue, then it's indeed a control board issue, nothing more.

Also, you did not give us any history about the miner, was it working on your network before or have you bought it used? because most used miners come with static IP that might have a different subnet mask from yours and thus it won't be accessible because it doesn't try to negotiate an IP address with the router, also, are you sure your router has DHCP enabled?

That's like putting your miner on a ventilator, it will be a matter of time before they fail again, in fact, you could do the opposite and you would still have a good sucesss rate based on my own personal experience, put the bad hash boards in the freezer (in a sealed plastic bag of course) and many of them will run fine for a few days, I hope I will turn out to be wrong in your case, but those 17 series are TRASH.

What NotFuzzyWarm explained seems to make sense, I am not an electronic expert but I can tell you what causes 99% of the issues for those trash miners, it's the solder that keeps the chips attached to the PCB, greedy bitmain seems to have accepted the lowest bidder and made zero efforts in testing the quality of that medium-heat solder, some people also claim that the robots that did the job were also bad, but what we know for sure, the solder causes the problem in many different ways.

You will find solder balls shorting the chips, chips that lost some part of that solder underneath them so some legs are not in contact anymore, and all sorts of other things that bad solder/soldering leads to, so I am guessing that another reason in addition to what NFW mentioned is the fact the putting those hash boards in oven might have melted a solder ball that was shorting the chip and it fell off somewhere where it isn't causing an issue anymore, which is great news assuming that no other solder balls appear somewhere else.

But what you doing is great, try to fix those trash miners at the cheapest cost possible because they are not worth it.

I know Phill loves mining, so why not do the opposite of that? bring in more gear, and make it worth it to hire someone to do the periodical check-ups, it doesn't have to be a salary, it could be paid per visit, or a percentage of income, I don't think it's impossible to find someone who is young, willing to learn a thing or two about maintaining a mining farm, lives nearby, and can be trusted.

It takes on average no more than half an hour a day, I'd say 3 hours a week is the average, a farm with 5ph makes roughly $350 a day, so even if that person asked for 100$/hr, it's just a matter of 3 something days worth of mining, I don't know about wages in the state where Phil's farm is located, but I highly doubt 100$, it will be on average 1 drive per week, any time of the day, 3 hours, reboot a device or two, change 2 fans, dust off a PSU and go home.

Ya, the same guy needs to ship a miner to another state for warranty repair and call the electric guy to come to fix something. Still, the work they will do doesn't require any special skills, so if I had to look for a guy like that,  trust and desire for work would be the only things I would look for.

It's hard to tell how someone got confused, but sure that mindrust isn't the average "post anything" kind of member, so I am sure something confused him along the way, I believe it's the fact that miners do indeed need DC, so to someone who doesn't understand much about the subject, they would not think that DC devices need AC power input, the logic behind it is not easy to understad.


Hard to tell how does he operates, his battery has the capctity of 28,800Kwh, so nearly 3 hours for the set up assuming 100% DoD, but if I had to guess, he is probably not running them at stock settings, S9s can run on Low-Power-Mode doing 750w range, L3s 600w range, and S19 1800w range. so we are talking 30-40% less power consumption for the whole set up, but let's hear from him.

You have got them mixed up, solar panels generate low voltage DC, asicminers just like most other electronics require AC at the PSU input, the PSU of course will have to convert that AC to DC to run the miner's chips, but you can't just feed the miner with DC and expect it to work, it won't for so many reasons that are not best fit in this topic.

Another pro tip, just mouse hover on the error when viewing the Whatsminer tools and it will tell you what the error means without having to fo to the miner webpage, also, double click on the miner's row takes you to the webpage of the miner.

I would like to thank you for both using my services as well as making the review, I would have loved to see you run both gears at the same place so we can compare temps, fans and power, doing so when each model runs in a different place with different voltage and cooling will not be fair.

230v is great, those m50 gears must be running without much effort, anything between 220v and 240v is good, higher is better for PSU, cables and everything else that carries power to the miner, slightly below 220v i would not bother, temprary below 210v is ok, but running steady for long period of time at 203v is something i won't reccomend, so ya sure thing call the electric guy, it is thier JOB to give you proper voltage input since you are paying for it.

@Sledge0001, I have bought and sold hunderds of the m30s, +, ++, various m50 models were sold to my clients, none of them hashed at specs, all run higher which is great and people loved it except for one client who was mad at me because i sold him some 100th m30++ which did 106th and he said his pdu was near full and could not handle the extra 200w per miner lol, luckly he was able to use powerlimit and did not insist on returning , I now have to make everyone aware that I won't be responsible for gears that do slightly higher hashrate than what is on the label.

Those can be somehow inaccurate since temps inside the farm will differ by a considerable margin depending on the airflow, turbulence, not enough exhaust causing heat to re-enter the miner, not enough intake space and etc.

As you can see the miners are reporting 25-26c while your sensor is reporting 18.4, that's off by nearly 7 degrees, it's always best to check the miner's temp sensor rather than external sensors.

But anyway, temps are still good, and don't worry much about them even if the room heats up, the miner will tune lower and will go into protection mode both on PSU and hashboard levels if temps can't be kept low enough.


That is pretty low, in my previous post I meant to say below 220v, which is the minimum stated by the manufacturer, but I have tested some M30s all the way down to 205v and they ran just fine, even those that threw a voltage error did not seem to bother and just kept going.

I am pretty interested in hearing the compassion part between the M30 and the M50 especially that now the price difference between the two is just about 2$ per th.

A pro tip, going to the Whatsminer Tool and going to display settings, you will find a lot of fun stuff to show like the daily power consumption, also you could exclude a lot of the not-so-important info like the power supply version and all that things that you won't need for daily monitoring, just to keep 4-6 columns that you actually use.

Let us check your voltage at the PSU meter, go to whatsminer tool and follow this.

 Settings > display mode > custom > add PowervIn

This will display the voltage at the PSU, yours seems to be below 200v which is why you get that error.

Also, you can add EnvTemp which is vrery useful too.
