Topic: Antminer S19 95TH setup - page 2. (Read 934 times)

Unfortunately, Amazon dismissed my claims, probably because this seller QIO TECH is moving a lot of product through them, on very weird/obscure reasons, so I had to escalate the issue, and I hope this will be dealt with in a positive manner. I told Amazon that it seems to me that it is not customer-service, but seller-service, no?
I do not understand, all manufacturers/sellers of bitcoin mining machines are that devious/weird from the customer service point of view? I had another issue with a USB miner that I sent back, and though I just opened the package, looked at whatever was inside, put them back in as they were packed, and closed the package, they dismissed this refund for the reason that "the content was not the same as originally packed". What?!
Amazon said they will take care if this one, however the one from QIO TECH, instead of sending it to HongKong, I will send it to a Quebec address supplied by the seller, where it is much cheaper, and Amazon said they will take care of the restocking fees. We will see how it goes.
However, this type of treatment of the customers that want to mine and use their mining machines, is not too positive. I was expecting them to be in the same way as the Bitcoin crowd, to be able to make a difference. Instead of shi..ing on the little man/customer, to treat him/her with respect.
Anyways, in the end the idea of mining is still appealing to me, however I would like to do it in a more profitable way, i.e. a faster machine eating less power, if possible, and I would need eventually, if you know, some suppliers that you eventually dealt with, or know that they still have integrity when dealing with customers, it would be great.
I was looking at www.viperatech.com/ and they have a lot of mining machines, however I do not know which one to pick. I know they are close to here, however I do not know how they are in terms of customer service...
If you would know some other sellers that have more some backbone as companies that sell miners, I would highly appreciate the info.
Thank you

Thank you for your response, and I understand your message.
I was looking actually, if I could get one with a price that is accessible to me, for a machine that does not need so much electric power (right now the price for KWh in Ontario is pretty high), and has a higher speed, TH/s. If you could tell me a source where I could get one, it would be great.
I was looking by myself for machines, and do not understand why machines for BTC mining are most of them produced in China, though China is prohibiting the ownership of BTC... However this is because I am still a noob...
Have a great day

The hashrate of each miner is subjective, it has everything to do with the algorithm it works on, in other words, a car that does 50km/h competing against 20 old men on wheelchairs is certainly a lot slower than a car that does 300km/h, but when latter is competing against a dozen ballistic missiles, the slow car is "better".

So ya, don't compare different miners from different algorithms, there could exist a miner with the speed of a few mega hashes that makes more "money" than a truckload of the fastest Sha256 miners, but you need to keep in mind the future competition, SHA256 difficulty is hard to move, 5% is considered a lot, whereby the overall difficulty of other smaller algorithms could easily double in a few days, so ya, there is more to it than meets the eye.

Sorry, I did not see that actually it was KH, and not TH. My bad.
I keep looking.
Do you have a good source that I could take into consideration?
Thank you.

Considering this area is for Bitcoin only you need to ask about altcoin (aka crap coin) hardware in the altcoin area like here

As for Not counting the fact that they are entirely different algorithms, in what world is 212KH/s faster than 95TH/s....

Hi guys,
I was actually thinking to buy a more performant miner, for instance the Bitmain Antminer X5 212KH/s 1350W (XMR)
What are your thoughts about it? The power is lower than the S19 95TH, and the speed is more than double.
Is there any way of calculating how profitable this machine would be?
Thank you

Thank you very much for the info Dave.
I will surely use this bit of info when I will talk to Amazon customer service.
What is very interesting though is that if you look at the page offering this miner on Amazon, there is also an offer for a "not new" miner, and it is some 250$ cheaper, so this would be a refurb of the refurb?
Weird. Normally, these type of miners should not be in sale anymore because, like it was for me, the cost of electric power in Ontario is forbidding the mining with those machines. The cost of power per day would be like 6.5$, and I managed to make almost 12$ in 3 days. If I would have had this info before purchasing this machine, I would have either bought a more powerful one, or not at all.
The issue was, in my situation, that the information on the https://www.bitcoinmining.com/ is very, very dated, and nobody thought of updating it with newer data. I was fortunate enough to find your forum, and this is when the lights finally went on. It would be nice, instead of all this useless info (like using USB miners that are nowadays a joke), to simply have a link to your forum where there is true shared experience, which I highly appreciated.
Thank you again to all who helped me till now, and happy mining! It seems that that ship sailed away for me, at least for the time being. I am thinking of alternatives.

The miner was not new, there have not been new S19 95TH out there for a while.
Lightly used / refurbished perhaps. But, not new.
Just saying this because if the seller / Amazon decide to give you a hassle about the return (doubtful since Amazon is very good with this) you could probably use that to help with getting your money back.

-Dave

Sincerely, when I began thinking about starting to mine, I wanted to make bitcoin, but also to contribute to the consensus that is still in the blockchain and keep it as Satoshi intended to have it. However, due to the subtle, and not so subtle, regulations that the existing fiat system introduced (regulation of companies dealing with crypto, the increasing of the price for electricity), the "true" mining becomes more and more difficult for those who truly want to maintain the original idea that the cypherpunks tried to implement. Unfortunately, the blockchain is more and more in the hands of people/companies with means that can afford the high electricity prices, and high machine prices. Machines like mine should be prohibited as they work in the disadvantage of the miner, or if they are left to be used, eventually encourage the mining with some incentives, probably from the mining pool side. Otherwise there will remain only the ones with means, that sometimes nobody knows if they eventually don't work for the fiat system (government, banks), and if the issue with the 51% comes into being, than the bitcoin will become just like any other fiat money.
I admit that I did not document myself too well before purchasing this machine, because otherwise I would either have bought a stronger one, or not at all, but I was enthused by the idea of bitcoin and the mining of it that I did not think of such a calculation. I assumed, and that was my mistake.
Unfortunately, I did not come to a complete agreement with the seller of the machine who tries to give me less than the price I payed for, invoking all kinds of reasons. They have very poor customer service, and I hope that Amazon will solve the issue somehow in my favour.
Therefore be warned, the QIO TECH company based in ShenZhen is very nice with you if the machine is working, however if you have not such a good luck, like me, they will invoke all kinds of reasons for not reimbursing you. It is sad that this is called "customer service". It is more like "company service" not caring too much about the customer.
So pray for me that I will see my money back from them.
Thank you again for all the support. You are a great team, a true spirit of the bitcoin idea of Satoshi Nakamoto.

It's great that you arrived at this conclusion in a very short period, the "short calculation" should have been done prior to purchasing the miner, you are lucky that you managed to return the miner -- most would have to sell it at a loss or use it as a doorstopper.

Being heavily involved in the mining industry makes it difficult for us to see how non-miners are so misled into thinking that bitcoin mining is profitable to everyone, most people don't even know how much their miner will consume, and not everyone is as brave as you are to admit their mistake, everyone who wants to start mining bitcoin should spend at least a week reading the different topics in this forum, they will get 90% of the information which would help them decide before investing a single dollar.

Hi guys,
After the whole discussion with the seller's and Amazon's customer services, I decided to return the miner.
Also, after making a short calculation, due to increasing electric energy prices in ON, the mining of BTC using this miner is loosing money. The miner is consuming some 10$/day, and I barely made 8$ in 2 days.
So, I am sorry to have to leave this community I was beginning to enjoy so much.
Thank you very much for your support guys!

Thank you very much MitMaxz for your reply.
I did not try to swap the cables. I just reseated them, i.e. unplugged/plugged them back where they were, and it did not make any difference.
I will try eventually to do what you say, however I would like to send the unit to be repaired as soon as possible, i.e. today, so that I can have it back as soon as possible.
Have a great day

I hope that you try checking the cable first by switching to another hashboard to confirm if it is just a cable or clean the copper bar with sandpaper as I suggested in my previous post but the sad part you end up sending it for repair.

Next time do some troubleshooting first before sending it for repair because sending it back for repair had a shipping cost.

Anyway, I'd like to give you a link that you can use for troubleshooting in the future and I hope it will be useful in the future if you experience some issues listed from the link below.

Hi Dave,
I talked to Larry from customer service and after all the things he suggested I do (I reseated the connectors that are underneath the above lid, upgraded the firmware, and restarted the miner), there were still 2 boards. Number 1 was still not available.
So now I have to send the Antminer across the country to Richmondhill, BC for repairs.
It looks a bit wrong as I have a brand new product that will become a "repaired" product that actually does not have the same value as the brand new one. He offered 80$ for the loss I would have in mining till the miner will be back from repairs. I am not too happy about the whole outcome, however if I talk to Amazon, I guess they will stick to the seller, and I will get my money back, if I get it back, in 30 days.
So I will send the miner for repairs in the end, and see what becomes from that.
I will call Amazon just to see what they say, however I am a bit disappointed in how they solve such issue.

They sent me a video on how to remove the upper housing to check the contacts for the connectors.
I am going to do that, and if it does not solve the issue, I hope they will send me another miner. Till now they were very friendly.
I hope it is a loose contact due to the transportation. It worked for a short while, and I had awesome hash rates, but very short.
In case they try to pull my leg, I will involve Amazon soon enough.
Thank you

Could be the power bar, could be the cable.
I would wait to hear back from the seller.
Here in *theory* taking it apart and checking the cables should not invalidate the warranty since you do have to pull miners apart now and then to clean out the dust.
In reality, since you bought it from a reseller through Amazon, they can make any rules they want about what you can and cannot do. I would wait to see what they say.

If they don't respond or fix it for you get Amazon involved as early in the process as possible.

-Dave

Hi BitMaxz,
Thank you for the offer. The only think about checking the contacts, I do not know how to do that w/o voiding the warranty, OK?

I hope you will find something.
Thank you

Can you share your miner logs I just want to check the logs if the 1st hashboard is still detected while it's not running properly we can maybe find the issue under the logs and give you some suggestions to try.

I guess that the 1st hashboard might had poor contact with the copper bar cleaning it with sandpaper might solve this.

Hi philipma1957,
I already did that 2 times, hoping what you were suggesting, and every time only 2 boards appeared, 2 & 3. Number 1 is not appearing.
Prior to my first restart, on the GUI, as I saw the hash rate dropping, I checked the boards and number 1 appeared in red with 0 hash. After I restarted the unit the first time, the board #1 did not appear anymore. Only 2 & 3.
It could be, as Dave suggested, that a contact got loose during the transportation, however I am reluctant of opening up the unit as this might void the warranty, so I am waiting for customer support to respond to my messages, and take it from there.
Thank you

try to restart it maybe it will go back to 3 boards.

Sometimes it is just a glitch and not a bad board.
