The reason why I asked you to show me the files you used is that I thought you could be using the wrong files, which seems like it, here is the correct list of files that has to be on the main directory of the Sdcard.



Download it from here > https://file12.bitmain.com/shop-product/firmware/adfcd6b0-88a0-4cbc-ac17-1bace3991b03/2020/09/27/10/SD_S17%2B.rar

The process is simple.

1- Format the Sdcard using FAT32
2- Unzip the file I put the link to and copy-paste the files inside it to the Sdcard

While that is true, it's unlikely to impact the temps to this degree, based on the kernel log the starting temp is pretty low and within 2 minutes it goes to 90c which is abnormal.

OP can you set the fans to 100% so we can confirm if this is indeed a temp issue, if it is, the miner should run fine with fans at full speed, or in the worst-case scenario it should run a little longer before reaching to the safety threshold of 90c.

Forget about mining altogether, honestly you will most certainly end up losing money with the power rate you have, mining at its core is competing against other miners, the two most important factors are the miner's efficiency and the power rate, the latter is a lot more important.

Even if you had the most efficient gear which is say the S19 pro, you still make only 15$ in profit after the power bill,  someone else who has 6 cents per KwH which is just the average in China, makes the same amount with an old T17 which he can get for 15% of the price you need to pay for that S19 pro, and you will need at least 2-3 years to ROI if ever.

In that case, you either used the wrong files in the Sdcard or the Scard is bad, can you show me what files did you place on the Sdcard you used?




We still can't see the image, you need to upload it and then copy the image URL not the URL you get in the browser, you need to right-click on the image and then copy the image URL.

Can you post the kernel log for one of the gears that recently went down? I also want you to try and disconnect all miners and keep only one running for 2-4 hours to see if acts any differently, if that's the case i'll tell you exactly what to troubleshoot, if the room is too cold try to set static fan speed using this trick, set the fans to 20% and watch them closely, you don't want them too cold or too hot.


I invested about 2 BTC in 17 series gears and some junky S9ks, all the S9ks are now in the trash and at least 80-90% of the 17 series is down, as of today's rate that's above 100k, you need to accept the fact that you are buying mining gears from a Chinese manufacturer that has little to no quality control and couldn't care less about the miners quality, it's a part of the game you are playing, just like when you open a shop and nobody shows up to buy anything, shit happens, don't blame yourself.

That's most likely just a re-submit feature because if they really do add your transaction to the next block or at any block which it doesn't deserve to be in then they will hurt their profit and the miners who use them, it makes zero economical sense for anyone to include transactions that are not paying the highest fees at the time of creating the block template, in fact, even those pools that provide it for a fee should share the profit with the miners because most pools are PPS+ and not FPPS, so the higher the fees the more the profit, if the pool is going to include low fee transactions then they are indirectly stealing from you.


I was never upset by you Kano, I just feel bad for you, you were one of the first pools in the mining industry, your attitude brought you down to the bottom of the list, you are not only hurting yourself but the folks who use your pool, if you were nice to the members here your pool's hashrate would have been a lot higher, I gave you this advice 2 years ago, but you just wouldn't listen.

Good luck.

Yes, this applies to all small pools, but the irony is that only 1 pool owner who spends most of his time bashing other pools, nobody does that but him, he thinks ALL mining pools are bad except his, which is funny for a pool that has not cracked a single block for nearly 300 days.

Also, there is a major difference between a solo pool where people know in advance that they are playing a lottery and a mining pool where people actually expect payouts, I point a tiny bit of my hashrate to cksolo for fun, knowing very well that it's most likely going to be a waste, but I get daily payouts mining on PPS pools, I can only imagine that I would feel like shit if my miners were hashing for nearly 300 days with not a single payout, and for all I know a small pool like Kano might never ever find a block again, it needs a lot of luck to be a luck of 100% which I don't see happening.

Anyone instead of Kano would try to make friends and attract people to his pool, but no, he continues to be mean and only make enemies instead of friends, anyway I hope whoever uses that pool gets lucky with the next epoch since we will likely have a major difficulty drop.

The topic is a mess, frod will be missed a big time.

So when you switch cables does the same board still work or is it the other one?

Example:

Board 1 ok, board 2 is bad.

After you change the cables which hash board is good is it 1 or 2?

Kano you are making stuff up just to trash other pools and promote your pool, you don't need more blocks to accelerate transactions, you just need to include them in blocks to be found sooner, OP's question is crystal clear if you don't get it - you have bigger issues to worry about.



Your pool has not found a block for almost a year now, it's as bad as those mining empty blocks, in fact it's even worse because empty blocks strengthen the blockchain by making it longer at least, your pool on the other hand does exactly nothing but waste energy, so maybe stop with the " my pool is the best pool" drama of yours.

 

Not sure what has your pool to do with the subject in hand, OP's question is crystal clear, he is not asking if he can increase the capacity or the volume of the blocks, he is asking about transactions accelerator which is possible and is being done on daily bases, of course, this can only be done with pools that find blocks on regular bases and not once in a blue moon.

If hash board 1 works fine for a while after a reboot and then it stops it's highly unlikely to be a software/firmware issue, it's either getting too hot due to a loose heatsink or something blocking the airflowg, or it simply is dying.

It could also be a PSU problem, to troubleshoot that, unplug one of the other hash boards and see if hash board 1 keeps mining, also since this is a rare gear and they have no official website to download the firmware from, you will need to get it from random links such as this one

That's mistake number one, don't use that firmware.



We can't see the image this way, you need to upload it here > https://imgbb.com/ and then copy-paste the link.




I'd say you did successfully flash it, but google chrome's cache is annoying, use a different browser or hit ctrl+F5 and your problems will go away for now.

If the flash doesn't fix the chips issues, please post the complete kernel log here, and don't forget to use the code tag

Reading this makes me sad, honestly, this is a BTC-related question, I hate to see it asked in the altcoin section.

To answer your question, first of all, the coal mine explosion in China (Xinjiang ) is real, pools reported an average of 25-30% drop in their reported hashrate right after the explosion, the hashrate drop happened to ALL sha256 coins, along with BCH price going up against BTC and what seemed like a larger drop in BCH hashrate compared to BTC percentage-wise, mining BCH was about 25% or more profitable than mining BTC.

More hash power was migrating from BTC which has already lost enough hashrate to other more profitable "back then" coins, which contributed more to the hashrate drop in BTC, but the migrating has a small impact compared to the mine explosion, why do I say so? because more than 30EH was gone from SHA256, all the other Altcoins combined don't make up 5EH of it, so even if they were 100% more profitable only 5EH would have migrated before we reach to an equilibrium of profitability across all SHA256 coins.

These profitability swings happen all time, coins are never equally profitable but usually, the difference isn't worth the switch, but when an altcoin price does 50% to the upside when and if bitcoin has not moved up as much, that coin will be a lot more profitable to mine for as long as the hashrate on that coin doesn't spike to utilize the price increment.

So if you want to catch those spikes it has to be automated, mining pools like Viabtc offer what's called Smart-Mining where they will use your hashrate to mine the most profitable SHA256 coin and then convert your payout to BTC if you set the auto-conversion on, eventually (just like the other day) you end up with 25% more bitcoin mining BCH and converting it to BTC as opposed to directly mining bitcoin.

---

Phill, sorry about what happened, I know you were not off-topic, I also think the majority of the community would agree to that, I dislike the forks of bitcoin just as much if not more than anyone else, but luckily I am opened minded enough to understand that mining is about profitability and profitability of SHA256 mining takes ALL SHA256 coins into account, the notion of not talking about altcoins profitability and how they affect bitcoin mining difficulty is flawed, it's like saying "don't mention the price of bitcoin in dollars because this is a BTC only section, take the fiat discussion to another section".

I understand your concern, but we have been having these diff threads for over 3 years now, there are a dozen of posts in those topics in which we discuss altcoins in the same manner phill discussed them in this topic, and guess what? none of them got deleted.

In fact, frodcopper who was the most strict mod probably in the whole crypto space merited some of those posts which were talking about altcoins in respect to Bitcoin difficulty, things back then were going smooth and nobody had to fork the topic because they felt like they were harassed for brining up altcoins in the same way they used to, also there was nobody who was afraid to ask a bitcoin difficulty related question.

I know you are not trying to have control over things and that your intentions are good, but this topic will eventually slow and die if it continues this way, and personally, since I don't want to argue with anyone, I'll be posting a lot less frequently here, if ever.

Good luck.

Thanks for the efforts.

That's because you don't flash firmware using an SD, you flash recovery files that would wipe out hiveon and then you flash the firmware version you want, please go to this website https://service.bitmain.com/support/download?product=Flashing%20SD%20card%20with%20image and download "t9+ -SD Tools.zip", unzip it into an Sdcard and make sure you change the jumper on the control board, all instructions can be found here https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery

Yes, it is your topic - you can do whatever you want, but rest assured many of us won't be participating in your topic if you censorship us based only on what you think is right, and we can always make our own topic to discuss bitcoin difficulty the way we see fit and let the admin decides what is off topic.

I wouldn't want to see this topic fork, i also wouldn't want to see phill's posts deleted for discussing how other coins profit impacts bitcoin hashrate because that is right on topic, but hey, do whatever makes you happy.

  

The average failure rate on the S9i should be a lot lower than that, but it's normal to be unfortunate and get a bad batch once in a while, the miner status shows temps are fine and fans aren't even above 50%, what is the relative humidity in the room they operate? if it isn't too high and since temps are good - I don't think there is anything you can do, you just need to accept your bad luck.

The kernel log structure looks so different to most kernel logs I have seen, it seems like it's some shitty custom firmware, can you try to flash 2018-2017 stock firmware and copy the kernel log from there?

You are late to the party, the difference was above 25% for some time and now it's almost even, thanks to smart-mining features on many major pools like Viabtc, they ensure that profit across all Sha256 based coins stays relatively even in the long run.

 


I believe the discussion was in respect to BTC difficulty which is affected by many factors, other Sha256 coins being more or less profitable to mine are one of those factors, we discuss rainy reason in china, chips shortage and many other things that affect bitcoin difficulty, talking about hashrate migrating from BTC to say BCH is neither different nor off-topic in my oppinion.
