Some custom firmware like Vnish and BO+ give you somehow an accurate wattage reading, it will still be in the -+2-3% range I guess, so if you are looking for a very accurate reading you will need a hardware watmetter of some kind, however, keep in mind that most of these meters are not rated for the power consumption of these miners, you will need something that can handle 3000w.

You need to flash the stock firmware by bitmain, point the miner to a different pool, let it run for a few hours and then post the complete kernel log here.

Post the complete kernel log, each hash board will have a product id of some kind in the begging of the kernel log, but to jump to the end of the story, the stock firmware is very strict with the board voltage which is stored in the EEPROMs, using custom firmware will likely fix the issue, Atermis3 mentioned BO+, I also know that vanish ignores the voltage readings and will work as long as all hash boards are the same model.

If however using custom firmware does not fix it, it could be a PSU-related issue whereby the PSU simply can't handle 3 hash boards, you will need to test the miner with a different PSU shall the prime persist with using custom firmware.

All of the S17 pro firmware versions are asicboost.


All the stock versions are pretty the same, the latest one has tighter security which can go against your desire when you want to change the firmware so it's not recommended.


In the miner status page, pay attention to the date.


If it's working no need to flash.



It's very unlikely that your router is causing this issue, it could be some IP conflict going on, it would be best to set a static IP for the miner which is outside of the router DHCP range, if you don't know how to do that just watch a few videos on youtubeظ

As mentioned early, I will do that for free, no problem, you might just have to stay up a bit late or wake up a bit too early so we both can be online, I am not sure about your timezone so that shall be the only problem.


He posted a screenshot of Viabtc not showing any workers, the f2pool was probably a typo, honestly, his problem is a bit strange.

You are right with the firmware lock, but this is a straight-out scam if you ask me, these were supposed to be "manufacturer refurbished", the ones in the video don't look anything like it, in fact, REAL refurbished miners are a lot more expensive than clean used miners, a while back used S9js were going for $250 while the refurbished once were going for at least $400, but those looked as good as new, no scratches, no lost screws, everything seemed like brand new, the miner in the video is a Used Miner with C- condition, selling it as a refurbished piece is nothing but scam IMO.

The stupidest advice I have heard in decades, someone is trying to run a business and your advice is to sell that business and go to the casino because solo mining with an Antminer S19j is in fact worse than gambling, and no, it's not 2 years, it's 25 years based on the current difficulty, it's a big NO.

I find it funny that Kano did not comment on this, seeing a newbie leading another newbie to the wrong path, instead, he took the chance to advertise his pool.

I don't think this is an IP/Network related issue by any means, your miners are connected and getting shares accepted, I suspect the worker name is wrong, I can see gonzalezfamily.002 on the miner, but not sure what is the account name on f2pool, make sure you copy-paste the exact account name.

On a side note, the URL you use is for a server-based in China, judging by your account name, you don't seem to be located anywhere near China, use the following if you are in or close to EU


If nothing works out, go ahead and create a Viabtc account then connect to it, your issue is most likely pool-related, if f2pool doesn't work, ditch it, if however, the problem persists after trying something different like viabtc / poolin or Binance pool, reach out to me via PM and set up Teamviewer/Anyesk I'll help you out at no cost,  but please, try a different pool first.

Why post 3 different posts with little to no arrangment? Not only that it goes against forum rules - it makes it hard to understand the content.

Please delete the two posts and merge them in OP, then post the complete kernel log for each miner. Also i don't like that long password you have on the pool worker, replace it with x.

I am glad we both agree that the hash boards are the main focus here, and this is why i mentioned above I don't see how both ways differ, someone mentioned that the sudden change of temperature will negatively affect the solder/themal epoxy, I can't confirm/deny that but if that was true, then still both ways will cause a sudden change in temps, in fact, leaving the fans on will make it even worse.

One thing I can tell you for sure is that if the miner isn't generating heat and the fans still spin and they are in wet weather with high humidity you will be in big trouble, this is probably why Bitmain's firmware keeps the hash boards on (generating heat) even if they disconnect from the internet, something that almost all custom firmware devs changed thinking it's a good way to save on the power bill, which makes sense for someone who has a perfect environment to sustain such a thing.

On a side but related note, Whatsminer community in this forum is rather small, it's only a few of us around, you might want to check the telegram community as it's pretty much a lot more active.

Unless you are planning to build a huge farm with a few EHs worth of hash rate, I don't see how it's related to difficulty. , now jokes aside, you don't need to create a new topic if you don't want to, danieleither has a similar basement setup, his farm is pretty neat if you ask me.

So back to the difficulty, the pace has slowed down from the last post phill posted two days ago, it went from being 5% faster to 2.5%, I am all convinced that the average jumps should be pretty small until next year, everything is lining up this way, if we get a few =>10% jumps then it will be hard to understand what is actually happening.

I find it hard to agree with this point, HODL is a lot less risky, you just need a proper hardware wallet to "store" the coin, your risks are limited, predictable, and avoidable, with mining, however, I can name tens of risks associated, many of which are not controllable by any means, people have no clue how hard is it to maintain a mining farm, but worrying about theft, fire, damaged PSUs, dead fans, heatsinks falling and all that is a lot of headaches and a lot of risk to be taken.

In some rare cases, mining is a lot more profitable than HODLing, remember that mining generates passive bitcoin, hodling does not (unless you are farming it in some stupid shit), so if you can buy 1 BTC worth gears today, and end up with say 1.5BTC after 12 months, hell ya that beats "hodl", but you need a streak of luck, cheap gear, good quality gear, cheap power rate and great timing for entry.

The sad truth is that most newbies buy the wrong gear for the wrong price at the worst time possible.

I honestly think nobody should deal with Myrig for now until they sort these delays and slow response issues (read OP), however, it's normal for the address to be like that, UPS offers "Store mailbox services", which is just another way of saying a PO Box with a full address, so it looks like Myrig are trying to hide their workshop address for some reason, that alone isn't something that will raise a big flag for me, but the other reasons mentioned above are pretty serious.

The new models come with SSh disabled by default, so it will be very unlikely to get SSH access on those, and yes, of course there is a security concern when SSH is enabled, it isn't as bad as publishing your email and password online, but it's an extra door for hackers to try and break, and most attacks on miners come via SSH which is why most manufacturers started to disable SSH in order to provide less support to their clients/ SSH victims.


I can't tell whether it would harm the hardware or not, but how does powering the miner off and pausing mining differ from one another? when you pause mining the control board will get the PSU to stop feeding power to the hash boards, so in other words, it's almost exactly similar to physical shutting the miner down as far as the hash boards are concerned.

In theory, it should be an order of magnitude better, although mining doesn't require that super-low latency, 4G as is pretty solid and has an average latency below 70ms according to my own experience, and mind you, the infrastructure here is not the best, so I doubt you will have any issues mining over 4G in terms of latency, your issue will be the bandwidth consumption, if you have a few gears that will be doable, if not, you have some issues.

To solve that you could use a mining proxy, but I have yet to find a stable proxy that I can trust with a few PH worths of hashrate, so that could be an issue.

Makes perfect sense, but the same could be applied for BO, they wrote a whole firmware from scratch, which does cost both time and money, I believe it's only fair that they charge a fee for that, I don't quite understand why Kano would say


Well, obviously that's how they get their "fees", of course, it's always a question of whether or not they direct your miner for a longer period than they promise, which is why to those who really want to use custom firmware - they should at least use a trusted version and not something random from the internet.

Whatsminer tool has remote control functions, one of them is (Suspend/Resume) mining, so that is somewhere to start from, also, if you don't use the latest firmware for the M20s you can still access the miner via SSH, so you can run a script to suspend and resume.



If that doesn't work out, you can always use something like "Sonoff Basic Smart Remote Control Wifi Switch" that controls a contactor that controls the miner power input, these smart plugs come with their own applications which you can shutdown/turnon from anywhere or set a timer for them, they switch costs about 3-5$ and the contactor is probably in the $15 range, not a very expensive project if the software road turns out to be a little bumpy.

It's rather simple, take total network hashrate (can be found using a simple google search, it's not 100% accurate and you can use diff to derive it but not that it matters given the scope) you divide it by your "potential" hash rate , you get a number X, that number is your "share" of the network, it simply means how many blocks on average you would wait to hit a block

So current bitcoin hashrate is around 130EH or 130,000,000 TH, with 100TH your chances are 1 in 1,300,000 for every block, since there is on average 144 blocks a day, you can divide that by 144 and you get 1 in 9,027 for TH. The difficulty / total hashrate was lower when the member above did that math, just goes out to show how a few days can make a lot of difference.

Now that you know you only have 1 in 9k chances mining with 100TH, you can apply the same math on your GPU, how fast does it hash, maybe 50MH? that is 0.00005TH, your chances per day will increase from 9027 to 18,055,555,555, that's nearly about 20,000,0000% less luck, mind you, 1 in 9027 is already as bad as it gets.

Grace on telegram @gracezhou1993 is a great source for spare parts, she usually has stock for everything, although I'd suspect the price to be on the high end for the 19 series PSUs because 1- many people reported issues with their PSUs so the demand is high 2- Bitmain doesn't make a whole lot of them, so I think the result is fairly obvious.
