Pressing the IP report for 15 seconds won't reset the miner, he needs to pre-press it before powering the miner on, and then keep pressing (don't let go) while powering on, hold for 5-10 seconds and then let go, that will reset the miner, however, it's extremely unlikely that it will fix any issues, I would recommend using Sdcard to flash the miner, and then trying a different firmware version.

The chips are in series, all of them need to be working, you seem to be having an issue with chip number 41, given the fact that this is a 17 model,  chances are the chip lost contact with the board, you will need some tools and skills to fix that, or send it somewhere for repair.

This section of the forum is related to Bitcoin mining, in other words, mining at its base layer and not the added services on top, your topic is related to a service more so than to mining, which means, it has to be in service discussion board, you can move the topic using the "move topic" button.

On a side but related note, you should be careful where to send your miners to, most host services are scams, most of the rest are far from honest, and only a handful are actually trustworthy, Kaboom rack and Scott are good resellers in the U.S, they might be of some help, again, you want to be careful and do your research before sending your mining gears to someone you don't know.

It depends on the miner version, the most common would be the chips themselves, there is no exact reason as to why that happens, it just happens, and it happens more often on some gears than the others, it's also common for PSUs to die.


Unless your voltage is out of the specified range labeled on the miner's PSU which is usually (220-240) it makes no sense to add those, or at least, the cost outweighs the benifit.


Buy them online, from places like Alibaba or Zeusbtc, some are cheap some are expensive, but that should be the least of your concern, the question is, will you be able to fix it yourself? if it's just a matter of a dead PSU or a dead fan, anyone can replace those, if it's a bad chip then you will need a lot of skills and tools to fix it.



It depends on the model, Some S9s have been mining non-stop since 2017, some S17s died after 2 months, it all depends on the quality of the miner and pretty much your luck, of course, keeping them clean and cool will at least in theory give them a longer lifespan, but the things you can do to "extend" their lifespan are pretty limited to taking good care of them, there isn't something you can buy and install on them that will magically make them live longer.

No, it does not depend on what BTC price does, this is MINING BTC vs BUYING BTC, bitcoin miners generate BTC and not fiat, when you buy a mining gear you are simply betting on bitcoin price to go up, so the question becomes "Will these miners generate more than 2 BTC"? if the answer is No, then buying BTC is without a doubt better than buying mining gears.

If BTC drops to 8k, then his mining gears will also drop in value, the rewards will drop and the ROI will be extended, in fact, it could be risker than just holding bitcoin, if the price stays that low for 2-3 years, the gears will most likely die before generating 2 BTC, while if you store 2 BTC in a safe place like cold wallet - nothing can happen to them, your 2 BTC will still be 2 BTC and you can just wait for the price to go up, which isn't the case with mining where you have to worry about electric bills, operational cost and the lifespan of the mining gears.

OP, on the scale of probability, you are likely going to lose money mining, go back in time to say 5 months ago, folks paid 15k for the same gear and they visited the same website you did, and it told them they would ROI in 12 months and life will be so pretty, today, they are looking the same website and it still says 12 months (actually more), and many of their gears died anyways, things are far more complicated than these calculators show you, there are many things that could go wrong, I am certain that if I randomly pick 10 miners, at least 7 of them would have done a lot better if they just bought the coin.

Hardware errors are very normal to have, it's a waste of time to try and determine what number of errors is good and whatnot, the most important would be your accepted hashrate on the pool, it accounts for all hardware errors, stale and rejected shares if your daily accepted average is very close to the hash rate that shows on your miner status page, then probably everything is fine, if it's off, then you need to troubleshoot.

Generally speaking, hardware errors is directly related to the hash board frequency, the higher the frequency the more errors you get, if you think for example the middle hash board is getting too many HW, then you will need to lower the frequency for that board, not sure if the firmware you use allows that, if it doesn't, there is nothing you can do about it.

Also, please do yourself a favor and stop mining to Antpool.



You probably mean 1.6/1.7 ph or 1600/1700 th. 

You are looking at the wrong data, you want to look for the file system version on the system> overview page, something like this



Ideally, you can get the commit version from the kernel log (not available for all miners), or the build date which is available on all miners, here is an example of one of my gears




If you go to their website, you will see the name of the firmware has a date in it, this is how they reference the versions they release, if you want the latest one you just download the one that has the most recent date, if it says 20201225 and yours is, for example, Wed Dec 25 09:47:07 CST 2019 then it's not the latest version.


Finally and most importantly you want to always avoid flashing the latest firmware unless you really have to, the latest versions does nothing more than making it more difficult to flash different firmware, if your miner is running anything 2018 or newer then it has Asicboost enabled, which is probably the only improvement bitmain did since the first firmware for the S9.

Not sure if this is done intentionally by Bitmain or just by chance, most custom firmware will stop the electricity flow in the chips when there is no connection to the pool because it does save power, which makes sense right? no mining going on, the miner shouldn't be consuming that much energy, however, the custom firmware in that aspect could be worse, first, you don't want your miner to get too hot, then too cold and then too hot in case your connection is going through a rough time.

The second point is that if the weather is wet, and your miner isn't generating any heat, yet, the fans are still spinning, water will condense around the miner and it will be  KaBOOM, so there isn't really a right or wrong way, both firmware custom and stock should give you an option as to what should happen when your miner isn't connected to the pool, and then depending on everybody's needs, they can choose what works for them.

I never liked the fan control of the stock firmware even on the older models, although it's not half as bad as it is with the S19 pro, they "could" fix that in future firmware releases but that could and will likely take forever, I see nothing wrong with setting static RPMs on your fans, it's what I have been doing for years and it works great, you will need to adjust it every couple of months (summer vs winter) and that's all about it.

شكرا لك اخ اوميقا على مواصلتك في تحديث المعلومات بخصوص هدا الموضوع واسف لانشغالي عنه بعض الشي, بناء على اقتراحك سوف اقوم باغلاق الموضوع.

Key word is "slow", hopping for difficulty to keep going down forever is wishful thinking, by default, it only goes up in the long run despite what the price does, based on that fact it would be great if difficulty goes up slowly and doesn't jump up by 50 or 100% in a few months.

They might as well just ask you to get lost and say you do not own any miners, thus, operating without being under a "legal umbrella" outside of your country is a huge risk, think about all the bad things that happened to those greedy folks who sent their miners thousands of miles away for cheap hosting, while many hosts were straight out scammers, some others were "smart" scammers, they would let your gear mine for say a month, and then tell you "The PSU was broken, you need to send a replacement or we can buy it for you locally to save you shipping time and cost", what choice do you have? pay them for the PSU, a few weeks later, the control board is dead, rinse and repeat.

It's completely impossible to conduct such business without

1- Being at the site physically

or

2- Trusting the other person 100%

Maintaining a large mining farm takes some serious manpower, do not listen to those who tell you it's just "plug n play" and you can just sit at home and earn BTC, there will always be issues that you need to attend to, the more miners you have the more likely you face issues, so are the Chinese going to send workers over to some other country? how about the Visa and all the legal documents? does Iran or Khazatitan or whatever potential country have enough people who know to maintain large mining farms? are they trustworthy? if not - back to square zero.

Mining in China was like heaven on earth, the Chinese will never find a better place, they had access to cheap gear, almost zero transportation cost, you just reverse the truck in one of the warehouses in Shenzen, load it up and drive for a few minutes or hours to your farm, as easy as it gets, how does that compare to transporting it to the port, getting all the customs clearing shit done in China, paying a large amount of money for shipping and insurance, going through the same custom clearing, import duties shit and then sending the gears to the farm!

In China, you could hire 50-100 experienced people to set up the farm in no time at a very low cost, elsewhere, you will pay a lot more to hire less experienced people to do that, or of course, you can send your own people from China which will come at another cost.

Another issue is the repair services, large miners in China were offered on-site repair services by Bitmain and other major mining gear manufacturers, your gear stops mining? call Bitmain and they will send someone to fix it at the site, what do you do when you have 1000 gears that need fixing in El Salvador?

All the above issues can be solved if enough money is thrown at them, but mining profitability is somehow tiny compared to the cost, every expense matters, all of these factors and more will slow down the reallocation of those gears.

There is custom firmware by the name "Luxor Tech" which I believe belongs to Luxor, so this makes 4 of them.

OP, I use AwesomeMiner and it's great, I have checked Mineitor and it looks as Awesome as AwesomeMiner.

Yes, it's just a tiny delay if

1- Your internet connection is fast in the first place
2- The VPN server is pretty close
3- The pool server is close to the VPN server you connect to
4- It's a paid VPN with a decent server

Of course, if you use a free service that is fully loaded with other users and is located on the other side of the globe then you are asking for trouble, but most VPN services now have servers all over the world, it's pretty easy to find a decent VPN server nearby.

This isn't a matter of what I or you think, anyone can try it and see the results to themselves.


It does matter, every share counts, and I rather get 0% stale shares, but if mine is 0.5% or 1% does that mean I should shut down my gears and move on with my life? it does seem like that is what you are suggesting, as a pool operator you have the code in place that takes care of this, if the work is submitted too late, you reject it, it's as simple as that.

Your concern is high latency, not the use of VPN, miner "A" could be mining to your pool with no VPN but with very high latency, on the other hand, miner "B" on a VPN may have very low latency to your pool compared to miner "A", to you, it does not matter, a share is either accepted or not, not sure what part of that you don't understand.


That makes two of us, I would be very pissed if I mined for almost a year and got zero rewards while wasting power bills and burning a few hash boards along the way.

Probably a combination of both, but "there's more to this than meets the eye", I spoke to one Chinese miner the other day, one of the biggest obstacles they seem to be having is "regulations", the Chinese have the money and the manpower but they don't like to operate outside of their region especially when they are not backed by the government.

Just imagine you own 20k gears in your hometown and you now have to take them elsewhere, think of how difficult it's going to be to manage it, you will need a ton of money, someone in a different country you can trust, a country where you can mine without having to worry about being forced to move out right after you set up everything, and of course, the power cost, it's a ton of work, to be honest.

It's easy to google countries with cheap power rates but moving there is not, even the so-called crypto-mining-friendly countries will not be as friendly when thousands of gears move there, more regulations will hit every country that has a large share of mining, mining will be a lot more difficult next year than it's now, the Chinese know that and they are being very skeptical, so when I see someone say "oh it's only 3GW worth of power, any small country can host those gears - it will happen next month", I can't help but laugh.

Some of them have already found a new home and it's only a matter of time before they go past space and power issues, but most gears are still in China, it will take a long time for these gears to settle somewhere else, and many old gears will simply not come back online.

That's true, but if 10ms gets you 0.001% stale shares and 100ms gets you 0.01% it's still within a good range of acceptance, the difference won't be even noticeable in the earnings.

The point here is that using VPN is not necessarily going to take you from 50ms to 300ms, depending on so many factors as mentioned above the added latency could be too small to be considered, in one of the small farms I have a very poor connection because the farm is located a bit far from the city, I use Ubiquiti p2p bridge to provide internet connectivity, the source itself is rather slow and have high latency because I can only use one shitty ISP, and despite all this mess, my accepted hashrate on the pool is well above 99% most of the time.

In other words, I have more latency than most other people even those who use VPN, so if someone has a fast and solid connection to a good VPN server they will probably do better than me.

If your miner can't do well at 34 degrees then something is wrong with your cooling method, also, the stock firmware handles the temps just fine to a certain degree, while it does not put the miner into sleep mode it simply reboots it, so despite not being the perfect solution one would hope for - it at least ensures that the miner won't catch fire.

Your post was not deleted, it was moved to the altcoin mining section where it belongs since that question was related to antminer L3 which is not a bitcoin mining gear, this topic is still there because it seems like you are asking a different question regarding a bitcoin miner. if you mention anything about altcoins this post will likely be moved as well.

Since he most likely not going to be solo mining with his own node, this is rather not important at all, the pool has that covered, if shares are submitted in time, they are accepted.

The reason why I said he needs to try on his own is the fact it all boils down to how fast the connection between his router and the VPN server is, and between the VPN server and the pool server, if the total time it takes for the packet to make a two-way trip is within a reasonable time window, then most of his shares would be accepted, I remember -CK mentioned <200ms is okay (can't find the post tho).

The problem here is that most people would use the ICMP protocol (ping) which is available in their OS and they will ping pool website, which will give you false results that could be far from accurate, what you need to use something like the Stratum-Ping tool which is available for free on Github, that will give you a lot more accurate results.

But the easiest way would be to try a few pools, I am positive that you can get lucky enough and find pools that are easily reachable by the VPN server you use and you end up mining with no issue, it will just take a few tests and some time but it's doable.




your data does not "bounce around the globe" when using a VPN, it just adds one more destination + the encryption time, if you use a proper VPN server that isn't fully loaded by other users, and the distance between you and that server isn't too far, you will barely notice the added latency and so won't the mining pool.



If mining is illegal in your country, you should not be doing it, using a VPN doesn't magically give you protection against the rules.

I have mentioned many times that we are unlikely to double the difficulty anytime soon and since last year my protection has been that difficulty will go up slowly unlike the common thought, but have I ever thought about going back to 14T? not even in my wildest dreams, if anyone told me this was going to happen a few months back I would have thought they were full of it.
