LOL.

There are a dozen members who sell mining gears here, and another dozen that offer escrow, you need to be insane to think that I have some sort of a secret deal with thousands of people.

I did not claim that you are a scammer despite the fact that I am seriously leaning towards that fact, what I said, is that since you are a newbie here and have no reputation you should accept forum escrow (a service which I don't provide FYI), but you insist on selling your gears without the use of escrow and expecting people to send you money first. if someone is stupid enough to do so, be my guest, I am trying to help YOU sell your gears if you are legit, nobody in their right mind would send money to a random newbie.

If you want to sell your gears, offer the use of escrow, this isn't a command, I don't own the place, I am giving you free advice and you are free to accept/reject it.

This and the fact that his sockpuppet accounts also signed in after 5 years of inactivity makes me think that he is 100% legit.


Nobody will escrow a gift card deal for a scammer, these gift cards might work instantly but then cause you other issues, your account can be suspended and whatnot, I would just stay away.

The problem with solar isn't that you can't calculate the consumption, this is false. also, the "old fashion" isn't more reliable, it all depends on your plans and the regulation of where you live, one exception, however, is that off-grid solar system is terrible for mining regardless of where do you live, the life-snap of all batteries is relatively short, and most folks don't understand that just because the sun shines at 8 am and sets at 8 pm you don't really get 12 hours of solar power, it's a LOT less than that, so the amount of backup you are going to need is HUGE.

And given the fact that all batteries have a limited cycle-life (depending on the DOD) you will have two major issues

1- You will pay a HUGE amount of batteries to cover up for the 16-22 hours on which your solar panels are not generating any power
2- The batteries will most likely die before you get to your ROI

Doing this on-grid however, and with the right "program" is a whole different story, the lifespan of the solar panels is way too long (decades-long) and you will have enough time to ROI, of course, you will be hit by a large initial payment which in some cases is better spent on more gears, but again, it's all about the incentives.

It's not up to Whatsminer to accept or deny the access, if you can locally access the miner on port 80 then you should be able to do so remotely, I believe your router could be blocking you because Whatsminer GUI has an issue with CA root cerficiate, most firewalls will flag it so this could be the reason why, you do to need to play with your router security settings which isn't something I would recommend, port forwarding to your miners is risky and things could go wrong.

You really need an extra PC on-site to be somehow on the safer side, it doesn't need to be a fancy one, get the cheapest one you can, I am sure you can find something for $100 or so, if you can't afford it, wait until you can.

Most of us here agree that "some" 3rd-party firmware out perform the stock firmware, however, I believe Kano's argument here is that these firmware versions violate the GNU General Public License, in fact, the stock firmware itself does the same since Bitmain refuses to publish the source code to "their" firmware, but since Kano allows them to use his pool he must have some weird theory behind why Bitmain is allowed to do that but not the others.

Not for a weird reason, the reason is you likely plugged both cables, right?


You are using a different firmware which refers to the kernel log as something else, whatever you posted here is not the "kernel log" we need even if it says so on the custom firmware, look for sys/system logs and post those.

The above is correct, but it's worth mentioning that it's the most reliable because it's compared against other shit-gears, the S17 pro "as is", is really bad when compared to anything outside of the 17 series, I would avoid the 17 series gears altogether, the failure rate is so high and you will likely start facing issues in the not too distant future since the miner has been online for 14 months already.

If you can find Avalon or MicroBT even at a slightly higher price, go for it.

This only because the miner is in a good condition, it would run just fine with the stock firmware, in other words, I don't think that nicehash firmware aka HiveOs is the reason why that miner is running stable.




Not that it matters to me at least I take all opinions equally regardless of the rank, in fact, many folks here who have legendary status and have been in this space for many years still don't understand the basics of bitcoin, but if for whatever reason you want to prove ownership of that addy you should at least sign a message.

Gave you 2 merit points for the efforts, it's great to see more video content in the forum.

Can you re-do the same test but with the TWO power cords plugged in?

Sorry, mad bad, I thought you were going all in solo, just thought I would let you know that you shouldn't be doing so, but since you are not doing it, that's a relief.


Solochance is pretty accurate, well, the math is rather simple to be honest, I did confirm that Solochance does the math the way it should be done ( I can't find the post but if you dig in the old posts of this topic you will find it).

With that being said, these are nothing but "statistics", luck variance is proportional to your total power, in reality, mining to a large pool only smooths/levels your payouts, a large pool can have a lot of variances and say 50% luck for 10 or 20 blocks, but in say a week or two it's luck will level up/down close to the 100% mark, a single S9 variance can take years to level out, this makes calculating your chances pretty "useless" even with 3PH when the network size is well above 100EH.

Of course, there is no argument about that, I believe everyone with common sense would agree to it, in fact, having enough ACs to cool down the hot air coming out from the miners, you will do just fine with no ventilation, but it all boils down to the most effienct way of doing it, cooling a server room is a completely different project.

My gears are located in one of the hottest cities on planet earth, they do just fine without ACs, which makes me positive that any other place would do just fine with enough fans, one important thing to note is pressure, our initial setup wasn't performing well enough because we were exhausting more air than we forced in, and you know that air will have to come in from somewhere, so this created negative pressure and the air was forced in from the exhaust side of the farm, we only noticed this after one of the exhaust fans died, it was spinning in the opposite direction (sucking air in), we also had miner fans failing at a high rate.

We ended up adding more intake fans to balance the pressure, the farm got A LOT cooler when the pressure issue was taken care of and so far, zero heat problem with absolutely ZERO ac units in that place.

One thing to keep in mind is that the power consumption and cost of a few large fans is a fraction of one large AC unit, also ACs require more regular maintenance/cleaning than fans do.

I have some serious doubts about your way of troubleshooting the PSU, it's a bit sophisticated and far from the normal PSUs, this could still be a bad fan or a faulty fan connector and not a dead PSU, try to use the fan from the other rail and make sure you plug both cables while testing.

Your hashrate is not tiny, it's too much to be risking on solo, and too small to hit a block on your own, I honestly don't know what the hell were you thinking pointing 3-5ph to a solo pool, you are risking a guaranteed win of about 1k per day to gamble on a solo pool, while your chances are a lot higher than those who point a single S9 or S7, you are nowhere close enough to hitting a block.

If that's hard to understand, think about it this way "You are closer to becoming a millionaire than Elon musk", many people will think that funny statement from the internet is false, but it's really true if you think about it twice, the same logic applies to gambling with 1k per day to hit a block, you have more chances of hitting a block, but the amount you risking is way too much and it isn't getting you close enough to a guaranteed block of any sort.

What I personally do is point the majority of my hashrate to PPS+ pools to get daily payouts, point only one or a few miners to cksolo for fun, I think this is the best rational approach.77

The miner should work just fine without the heatsinks as long as the heatsink isn't shorting the other once, it will get to the point where you can feel the heat coming out from the miner but then it will show a temp-error and stop, so you don't really need to stick that heatsink just for testing purposes.

The kernel log is not complete, after the 30s sleep which usually takes a bit longer than 30 seconds, it should start testing the chips on all the connected chains, so allow more time and then post the rest of the following log because that part is what actually matters.

However, at first glance, it seems like you might have a faulty PSU, there are a few things to do to troubleshoot it but I rather see the complete kernel logs from the original firmware before arriving at conclusions.

I sadly believe the same, seeing how passionate he was about moderating the mining boards, it's very unlikely that he would leave for no reason, he has always been criticized by many members before and he probably grew a very thick skin so I don't think someone pissed him off and got him to leave, one thing to notice is that frod is from (and probably lives) in one of the countries that had a new recent pandemic wave and the positive cases have been skyrocketing there for weeks now, I hope he is safe and healthy because that's all that matters.

With that being said, I hope nobody does more digging on him, if he is well and happy to be away from the forum, leave him be.

I was aware of this almost a few hours after he was removed, I only noticed this topic after ChuckBuck mentioned my name.



While I do disagree with a few things frod used to do, I am certain that the mining board was a lot better when he was around.

I am one of the most active members in the section, I watch every child board in it every day even when I don't post. When frod was around the amount of spam was close to zero, we hardly had the time to report any post as he was actively removing spam around the clock, he even did a great job in arranging different topics in their appropriate child board, that task alone is a lot of work.

Since he left, the amount of spam went up, not by a lot simply for two reasons.

1- Most spammers probably are not aware of the fact that he left.
2- He left at the bearish/no so spam friendly time.

I am pretty sure that when BTC hits new ATH and mining become very attractive again, the mining board will have to deal with a lot of spam, I report a few posts every day since he left which I didn't have to because he took care of it all.

Another thing I noticed after he left is that many topics are put in the wrong child board, the child boards can be very confusing to most new members, even to old members who are not active in the mining board, as for now, I am so glad that whoever handles our reports actually agrees to move topics to where we ask them to, although, I am pretty sure most mods won't understand why do we request moving a topic from board A to board B, it's like a general consensus that was build between the members of that section, so I do hope the mods keep moving topics to their appropriate child boards based on the community requests to keep things as neat as possible.

With that being said,I don't think we need a new mod, for now, we just need the miners' community to start utilizing the reports more and more, it's a habit we need to develop now since we didn't really have to when frod was around, i am positive the mining community will overcome this and continue to be the most anti-spam section in this forum.

Frod, despite all the arguments I had with you, you did a great job and you shall be remembered. Thank you

I think the S9 price has been the same for years when you take the ROI in days excluding the power bill, it now goes for $400 and makes about $90 a month, It was about $800 when it made about $150 and when it made only a dollar or less per day last year it was going for about $100, so really the average is 4-5 months ROI if you have free power, of course, sudden BTC price increase create some temporary "unrealistic" demand which would extend the average but that only lasts for a while and then we eventually fall back into the 4-5 ROI based price.

I also believe this is true for all other gears, this is why I ALWAYS tell people here not to buy overpriced gears that can't (at least on paper) ROI in 6-8 months, those who paid 15-16k for S19 pro are now in deep shit, their gear now worths 20-30% less and makes 20-30% less profit, the only price that makes sense for an S19 pro now is around 6k, anything above that and you will probably never ROI, the math is rather simple, but most folks just don't seem to care.

You can split the kernel log into 2 posts to get around the forum limits.


Actually, it takes a lot more than soldering knowledge to fix these boards, you will need some tools and skills, so unless you are planning to do this large scale it really isn't worth investing your time and money just to fix one or two hash boards.

اعتقد ان الجميع يريد استخدام المنصات اللامركزية ولكن للاسف فهيا بعيدة كل البعد عن منافسة المنصات المركزية بصورتها الحالية, والمشكلة الاكبر ان اصل المشكلة يكمن في طبيعة عمل البلوك تشين اي ان تجاوز المشكلة ليس بالامر السهل, المنصات اللامركزية مبنية على البيع والشراء على البلوك تشين نفسه, لذلك فهيا باهضة وهدا الامر طبيعي, البيع والشراء في المنصات المركزية لايكلف حتى 0.001% من تكلفة عملية حقيقية على البلوك تشين لذلك فحتى لو تمكنت المنصات اللامركزية من تحسين واجهة الاستخدام وضافة خصائص وامر البيع والشراء ووقف الخسارة وحجز الربح و و و فسيكون عليها حل مشكلة تكاليف الشبكة والتي بحلها يجب عليها التنازل عن بعض الخصوصية او الامان.

يوجد ايضا مشكلة كبيرة في التعامل مع المنصات اللامركزية وهي  miner-extractable value او Front Running, تخيل ان تكلفة التحولي الواحد على Uniswap عندما حدث الهبوط العنيف تجاوزت ال 500$, الامر ليس منطقي ابدا.

They do, in one of the small farms I have I still use an AC to help cool down the miners when the outside temperature is above 35c, but after doing this for many years, I got to the conclusion that you don't need an AC if you can move enough air, these miners will run just fine even at an ambient temperature of over 40c, we have 150 gears in one of the places that have 0 ACs in it, we run most of them at stock settings and a few days ago the outside temperature was as high as 40c and the miners were running pretty cool.
