They basically told me that these were the worse units that bitmain produced and has had a ton of issues.
I have been saying this for months or perhaps years on this forum, I kept mentioning how bad the 17 series mining gears are on every occasion I saw possible, I did that to the extreme that someone accused me of "fud", I can't blame them, it did sound like I own a Bitmain competitor company. Phill is probably the only one I know who didn't have a high failure rate, the vast majority of people I know had well over 30% failure rate, some are above 50% in less than a year, this is so unfortunate given that most of us bought those gears when BTC price was at or below 10k. It's a lesson learned, I hope more people become aware of that, if you don't have the tools and skills needed to fix these gears DO NOT buy them.

Is there a flash upgrade for the S9's to take them to +3 th/s?
This should be in the mining support board instead. Short answer: NO Long answer: This is probably a glitch in btcTool, the multi-option firmware has an option to underclock the miner by 3 terahash but a maximum of 2 terahash for the overclock, you should NOT attempt a firmware upgrade, the latest version has no tuning options and you probably can't revert to the 2019 firmware which has the drop-down options for tuning, I also believe +2th is already good enough to sustain your miners anyway, don't push them hard.

If I had to count the cost of importing from a country outside the European Union I think we would easily have to add 30%.
Then you should try to source them locally, make a WTB in the market place/hardware section https://bitcointalk.org/index.php?board=75.0. Make sure you either have a F2F meeting with the seller or ask for escrow, phill would escrow that I believe. If I wanted to start small, would it be a good idea to buy a revised or even a new used Bitmain S9?
With your low power rate, you can make a decent profit with an S9 and most importantly get the hang of how mining actually works, all of that while risking well below 1k instead of 14k.

For those who know, are the S19 Pro that can be found at reputable sellers on Alibaba the same as ordering on the Bitmain site?
Avoid Alibaba like the plague, you can find other trusted sellers on this forum, but do you really want to pay close to 14k for a miner? what about tax, how much do you have to pay to import a miner like that? Do you think this information sounds realistic?
They don't, this is based on static difficulty and price which we all know is impossible, it all depends on your luck, let's assume difficulty is going to be same if bitcoin price goes to 150k the S19 pro at your power cost will make you about 3k a month, so for 14k investment, you would need a little under 6 months to ROI, if however, bitcoin price drops to 27k, your miner will make you $500 a month, and that will be over two years to ROI. To put this in a simple and yet somehow accurate way, when you buy bitcoin mining gear you are essentially betting on the price to go up if you believe that will be case until you hit ROI, then go ahead, if not - don't. The point here is not to get your hopes so high, know that the difficulty is only going to go up and the price can't go up forever, if you understand the risk and the dark side of mining then mining is a great business, if you don't, you will end up losing money just the like the majority of people who invest in something they don't quite understand.

Keep in mind only the repair shops located in China are actually certified by them, the rest are not, and they state that clearly on their website, however, I'd imagine they do some basic due diligence before listing anyone, still, deal with cautious. If they don't reply you let me know, I have quite a solid relationship with Kevin, and I am trying to get him to treat bitcointalk members with a bit of a priority and offer them some discount, I believe sometime in the future I may get him to sign up to the forum or put one of his staff here for the forum members to interact with Zeusbtc directly on the forum.

I have a quick question, I live in France and the delivery of the first Bitmain Antminer S19 Pro 110 TH / s is expected around the month of August. If I understand correctly from the posts I have seen in the forum there are in some countries people who have already received their Bitmain Antminer S19 Pro 110 TH / s, is this possible? Are there priority countries? There are no priority countries except for China, and the Chinese buy from the Chinese website, not the English one. I also don't understand on what bases do you think this is the 1st batch of Antminer S19 pro, it isn't, it has been out there for months (close to a year), so yes, some people who ordered early have already received their S19 pro, the rest are waiting. On a side but related note, the August batch is for those who ordered last month or the month before IIRC. Right now, everything is out of stock, and would IMO continue to be the case for months to come, I believe the spot price for S19 pro now is $13-14k, I have not checked it today but the S19 non-pro is 10.5k.

I almost forgot I made this bitcoin bottom analysis more than 2 years ago, It has been a wild journey ever since, I believe in a few months I shall be posting another analysis on how bitcoin has likely topped, interesting times ahead, I take this chance to praise everyone (myself included ) for staying strong when the majority of people were in panic mode, it's easy now to look back and say, oh, it was obvious and simple! since 2 years have passed and the price moved from 3k to over 50k, but it was certainly not easy then. Those who were strong enough to enter when all the media and 90% of everyone around them was telling them BTC was going to zero, congratulations you deserve to own bitcoin when everyone wants to buy it for 50k.

If you look at a the chances of being ahead or behind at each block of an epoch, you are more likely to be equal to or ahead than behind through the whole epoch, but getting closer and closer to 50/50 as you get to the end.
Aha, exactly what I mean, of course by 700 blocks we get close to 1/3 of the epoch lifespan which would get as closer to the mean, unlike when we view the results at say block no.100 or so. Well, the data is available, so maybe if I get ambitious I'll look at the blocks from the last couple epochs to see what we might be able infer. All you need are the timestamps of the blocks to re-create the % ahead/behind.
The timestamp is inaccurate, you will see blocks mined in the past or way ahead into the future, the most accurate would be the actual time a block was submitted, not sure if any of the explorers out there keep track of that, but if you want just the timestamps LoyceV has it here in a single file.

Given who they are my guess is host their own pool at their datacenters for their customers.
Makes sense, I didn't even bother reading their username, anyway I just wanted to confirm they actually do know what setting up your own pool means, I know some newbies would want to do that to evade mining pool fees. Yes the post was deleted. I don't know why. I am testing different open source softwares. Thanks for your answer I will check db record and will get back to you.
Probably the admin thought it was spam or something, I hope they won't delete this one too, anyway, check and let me know, if you didn't find it I'll take another look into the backend code on Github.

Was your other post deleted? I answered your question on that topic, not sure what happened!!
You need to use a username and not a wallet address, that user name needs to be in your db, I looked into the table name and I forgot it, but there will be user/worker database table, the worker name needs to match with one of the rows in there, only then it will show alive.
As far as connecting that to your wallet, you have to know that you are now running your own pool, so you need to find a block to get any rewards, search the code and you will find "genesis transaction" that's where your wallet address goes to.
May I ask what are you trying to achieve by running your own copy of btc.com?

Um, no. If the hashrate was 100% flat, over long enough time scale the average diff would be flat.
By long enough I suppose you mean infinity? I believe we are on the same boat but with a little bit of confusion, let's "for fun" work with the time between blocks which follows the exponential distribution as it's a lot easier to understand than the Poisson distribution which is the number of blocks found in x time follows. Using the cumulative distribution function we get this nice and simple result. Notice how almost 40% of blocks come after less than 5 mins from the previous one, we will just assume the epoch just started and we are now at block 10, based on the CDF Block 0 > =<5 mins > block 1 Block 1 > =<5 mins > block 2 Block 2 > =<5 mins > block 3 BLock3 >=<5 mins > block 4 Block 5 >=<10 mins > block 6 Block 6 >=<10 mins > block 7 Block 7 >=<15 mins >block 8 Block 8 >=<15mins > block 9 Block 9 >=<20 mins >block 10 The order does not matter, and this isn't really how it works by the way , but without a doubt finding the first 10 blocks will in theory (based on static hashrate) take less than 100 mins, let's just assume it takes 95 mins, this will automatically set the cryptdiff to a base of +5% which would indicate that we have 5% more hashrate when we are not even close to that. The deviation from the mean will eventually drop closer to zero as we move further, but when the sample is too small the slightest deviation makes a large impact, Back to my earlier post about the chances of being 10% ahead after 700 blocks when the hashrate was actually flat, that is the chance of getting 700 blocks or more when on average we would expect 636 (not 770 vs 700 like I said before), that would be 0.649% (1 in 154 times). So you might expect that to happen once every 6 or so years... doing that 3 times consecutively is 1 in 3.6 million.... so once in 140,000 years... lol.
It was indeed not flat or else it can't go to 10%, chances are slim to nothing as you have explained since we are now only 4 blocks away and now the number shows 1.3% we can safely assume that this is going to be accurate, and we can for the sake of argument say this has been it since the beginning of this epoch. In 20 mins or so we will hit a new diff epoch, let's try to take as many screenshots/copy-paste the data so we can discuss it further when we actually get to 700 blocks.

Well looks like you didn't become the top after all and sold out to p00in They advertise themselves as "the top mining pool in North America" or at least that was their mission, I am pretty sure most of their clients joined them for that exact reason, another portion must have joined them because they are Non-Chinese which was a bit of a counter measurement against Chinese mining pools, and the irony is that they had to capitulate to the largest mining pool which so happened to be Chinese. (though no pool except mine seems to do this analysis anyway)
It seems like nowadays all you need is a ton of BTC to own a large mining pool, Binance is a newbie in the mining industry, with less than a year around they managed to secure 10% of the total hashrate, it doesn't seem like the perfect code and analysis matter anymore, just own enough bitcoin to offer 1-2 months of free PPS+ payment and you end up with 16EH worth of hashrate.

Phill, I like the theory but I don't think it's remotely possible, at the current price range it makes 0 sense to turn off 6EH worth of hash power, if Bitmain and Via were sitting on a 6EH they would never turn them off, at the current prices, it doesn't matter if you pay 5 cents or 10 cents, profits are still decent, your theory would make sense if the drop in hashrate was right after a price drop, say Bitmain and Via directly and instantly converting BTC to USD with a good enough margin to the downside, and the bot triggered at x price range to switch from 100TH back to 80TH mode, that would make some sense.
However, the price after the first 5 days is a lot higher, which means if anything, bitmain would be overclocking the heck out of those gears if they had them, bitmain is not under any obligation or law that forces them to run miners at x speed, you pay for 100th you get 100th, how and what they do to get it for you is nobody's concern, so if they have say 20EH worth of power and only 10EH worth of contracts is sold, with BTC at 50k I would bet my house that they would be mining full blast with it.
In other words, the power they save switching from 110th to 80th is nothing compared to the reward, and to make this a lot easier think just 1 S19 and 6 cents per khw.
110TH / 3500w = profit $42.69 and 5.04$ for the power bill = $37.65 daily net profit 80TH / 1600w = profit $30 and 2.3 $ for the pwoer bill = $27$ daily profit = a net loss of $10.6 per miner
Keep in mind that 80th/1600w is based on 20w/th efficiency which isn't even possible.

Yes, there is it will be released soon Future post: Date: 2024 Author: Taserz "It will be released soon" Have done 85T on a m20s drawing I think 4.4kw iirc.
That's a toaster, the max power draw for M20s PSU is 3.8kw no? did you guys mod the PSU too? jokes aside, I believe the focus on the M20/M21 should mainly be on the underclock side, MicroBT gears are power-hungry, also the single cable plug on the PSU makes it inconvenient to a lot of folks.

سأجيب فقط على جزئية افضل العملات للاستمار الطويل المدى, اعتقد انه وبدون شك لن يكون 50% من استتمارك في البتكوين, 25% ايثيريوم واما ال 25% يمكن توزيعها على عملات اخرى كما تشاء, شخصيا لا احب عملة ريبل ولا اعتقد ان لها اي مستقبل واعتقد انها سوف تختفي من الوجود في السنوات القادمة, والله اعلم!.

Yeah, another great diff jump for mining. 2021 seems on making up for 2020 is on its mind.
If we do 1% jumps over and over we will whale.
I wish I had enough time to dig back into my old posts to praise myself, I have been "bearish" on the difficulty for a while, IIRC i said we will do 3-5% for most epochs to come, I might was wrong with one adjustment, I didn't keep track but overall I am still on track, which makes everyone happy I suppose, including the difficulty bulls. at blocks 1-700 we are way up like 10% and then we drift back to 1-3%
A huge part of it is what Kano explained, I am not sure if everyone knows that already but even if the hashrate was 100% flat throughout the 2016 blocks, we will always adjust positively, that's because given the meantime for blocks is 600 seconds, 63.2% blocks are subject to be solved in <600 seconds aka; less than 10 mins and only 36.7% of blocks are found in more than 600 seconds. So when we first start a fresh epoch, even with static hashrate blocks will be mined in less than 10 mins on average, the cryptodiff website we use isn't inaccurate because the dev lacks intelligence as someone tries to make them seem like, but that variance over a small sample results in some inaccurate results due to how statistics are, the website uses simple math with no statistics involved, they could, of course, factor the CDF of the exponential distribution in their website, but that will take a lot of work.

There's lot of mod available for Bitmain but can't find any for other manufacturer. Why ? Because most mining gears out there are made by Bitmain, I believe there are at least 8 Bitmain Antminers for every Avalon and Whatsminer out there, so the custom firmware devs try to target the majority of miners which is pretty logical. The second reason is what NFW states above, the only reason I use custom firmware is that it does fix some broken miners and gives me the basic tweaks I need that the stock doesn't have, but the other miners have at least the base settings which reduces the need for any custom firmware that has fees on it, honestly, if Bitmain slightly improves their firmware the custom firmware market will take a big hit, but alas, they seem like they are happy with how things are. On a side but related note, I know Vnish team is working on MicroBT firmware, I have no clue about the exact process, but when any dev tells you "soon", it could be 4 years.

So after measurement, at the plug that goes into the miner, I got exactly 244 volts. So the lack of power does not seem to be an issue.
But you are slightly above specs which is as bad as being under it, the specs on their website say " 210~240V", it's only a 4volt difference but might be worth looking into. ... which leads me to think there is a heat sensor issue. Could I be onto something?
Each hash board has its own sensor/s, the likelihood hood of all temp sensors dying together on the same miner is pretty low. Doesn't Inno provide some sort of Kernel log? I suppose they do, please post the full logs here. My initial guess is power-related issues, second, comes the network, but I am hoping to find some clues in the kernel log.
