I'm thinking most conviinient is to freeze the whole miner:) and pick up used freezer cheap on the way???

miners.eu have good prices on etherum miners, much better than Prominerz, which seem  to "trusted" pricing policy by up to 20% compared to miners.eu. It seems there some talking  regarding "negative elements" making it hard to distinguish inbetween the vendors, scamers i.e unhappy buyers, competitors trying to miscredit each other as scammers. Whats your opion on that? Is asicminervalue.com to be a trusted  as non afiliated party? They have markings "trusted" on some vendors (obviously  based on some simple algortim, but still they are risking to discredit thier trademark if they are deviating with their "Trusted" marks to much. Just my 2 cents.

That is good news, temps look good too, I will try the trick soon, I will need to go the farm to pick up all the dead 17 series, I have a lot of them, since the trick is cheap and easy it's worth the try.


Nop, they are likely scammers, there are a few accusations against them in this thread , also their Trustpilot reviews aren't great, see one thing to notice about Trustpilot is that positive reviews can be faked easily because they require no proof, while negatives require verifications such as emails, screenshots and all that, the seller can dispute against your negative feedback and have it deleted, so negative feedback outweighs a 100 positive once.

Here is one recent feedback:


Nobody knows or trusts John, but the fact that his verified negative feedback is still there simply means that the accused party failed to prove that John is lying, which means they have indeed scammed him.

Yes it's still stable since i started it, even though i OC it a little to kompensate for the dead card.


going to try to fix the dead card once i get the board fixture, but i thnk it will require a lot of expirience and gear to rework the ASIC chip. Anyone that did this operation with good outcome?

By the way is miners.eu a trusted vendor?

Thanks for finding the post, I started this topic to help the mining community locate repair services nearby, since sending gears back to China isn't working as it should, I believe this thread would be very helpful, I hope that we all band together to grow the list in that topic.

Found the post where phil recommends a repair place. Not sure if those prices are up to date, the web site currently says $150/$250 for basic/advanced repair.

Indeed, I think they trapped him into sending his gear by quoting him an estimate of $30 to fix his S17+, what kind of a fix would bitmain put their staff on for $30  , anyway, people should look for alternative ways to fix their gears, check zeusbtc or ask other forum members about workshops that are specialized in mining, phill knows a few in the U.S he perhaps should make a dedicated topic in regards to that.

Bitmain doesn't really shame on their dirty ways of making money for the owners!    

They are lying to you, used S17+ go for above $1500, for $1127 you can only get S17-56th.


Point number 4 is really funny, they want to persuade you to sell them the miner at a much cheaper rate, nobody is going to pay 90%, they will be that "buyer" so (1127-30$)*0.9 = $987.3, also expect a 5-10% less with an excuse of bitcoin price is lower on the exchange they use.

Sorry that this is happening to you man, Bitmain is indeed a terrible company to deal with.

Wow ... so they want to keep your property and won't even compensate you in real $, but 10% max coupons instead! Unreal. The things people/companies/governments are doing using the COVID excuse are just awful.

I sent my defective S17 + 67 to Bitmain for repair on October 29th (out of warranty). After several inquiries about the status of my order, I received an email from Bitmain yesterday:


Unfortunately, that was not the solution that I would have expected! after paying 50 € for shipping and 30 $ to Bitmain for the estimate.

Now I don't know what to do. and I wonder if the S19 I have ordered will arrive.

Well ... Can't argue with results but I doubt it will be a very permanent fix. I'm also curious if it is still running.

My only guess would be that the issue was a bad solder joint and the thermal cycle expansion/contraction moved the bad connection enough to make contact. Or maybe the residual flux that may be keeping some stray solder balls in place that leaked out during heatsink application gets brittle enough to flake off when cold.

So how is the frozen hashboard doing now? I know the freezing trick works on weakening the adhesive and make the heatsink easier to remove, not exactly sure how it would help to make it stick harder!! I would love to hear more from other members, NFW and wndsnb can perhaps shed some light on the subject.

I dont now if  anyone noticed the "freezer trick" in this video posted above, https://youtu.be/F6L9hCQ4OhY ,I had some parts of it tranlated by i russian speking friend, and it turned that some hashboard problems can be detected by freezing the board, and there after run it.

I took the hash board board (0) from the T17, that droped off or didn't start, that on irregular bases, (in awesom showing ...4 of 30 asic...) and put it in the freezer for a couple of hours, and it felt stable there after, now on day 2, been minning normal and also starts normal on multible power cycles.

I dont know the exact mechanism for this phenomena, as the dude couldn't explain to well, but as its known that bad quality of solder composition/flux, migth be affected by prolonged heat exposure, resulting in bad solder joints due to  crystallic changes in the solderit self. The process of freezing migth some how mediate some  transformation the solder.  Let see how long this fix will hold... Worth trying on such boards.

To the other board [1] i attached the heat sink with thermal glue but to no awail, still showing (..24 of 30 ASICS..) freezing did not help on this one.

Just to be crystal clear here, my main objective was related to price and availability only, I assumed because east Europe has more mining operation then mining-related stuff would be cheaper and easier to find, but as far as integrity, or lack thereof, I am sure you know much better than I do.


1 - PLEASE don't overclock these gears, they are very very sensitive, they barely run for long enough at stock settings, overclocking them is extremely risky.
2 - The fact that some overclocking was enough to blow those fuses, you might actually be pushing them the max anyway, the same thing would have happened if you had a sudden drop in voltage and your gears needed to draw more amps, so be careful.

I agree that Switcherland is a odd place for a Crypto miner outlet, but on the other hand crypto have no borders no time zones. Back then it was one of the few reliable outlets in Europe. They mainly profited on antminer customers, that either missed out on ordering or got to few from Bitmains batches,and saw crypto prices surge. I think prices then was like 25% higher compared to Bitmain, but i was able to buy excl. VAT. got some z11 there. From my point of veiw, ordering, paying in advance, from a Swiss company, on wich i could get info on the net and so on, contra an Asian company (ex Bitmain) was no brainer.

But idont agree on that eastern europe, should be a more reliable and/or convient, chances to be scammed is in my opion higher in east EU. In general (not crypto bussinessin particular) It still carries a shady reputation from the past. Corruption is higher (maybee not everyone will agree with but lif its out of topic i'll remove it) But on the other han eastern europe is expirienced regarding crypto, land got a larger crypto community then in west, mainly becuase of the historical mistrust towards gowerments, insitutions and banks. In some west Eu countries, like Sweden, knowledge about crypto, in mainstream population is almost non existing.

Sorry for massive of typos, but tired lika dog, becuase of a rough day, tuning all the miners to a maximum. Unfortianly i went one step to high in the auto tunning, and in the end i blow the main fuses, 4x80amps, supplying the farm, then i just threw in the towel and went home.

You lose nothing if you contact them, it's just doesn't line up perfectly, Switzerland and mining don't seem to blend well, I mean who on earth would start a mining business in that expensive country? were prices near the reasonable back in 2019 when you bought the gears? I think what you should look for is a supplier in Eastern Europe, mining there is a thing and probably the supplier's option is much better on that side of the continent.

Ok i'll find something. Another reliable shop is Prominerz in Switzerland. I bougth some miners there to in 2019, i donnu their ability in spares, maybe on reguest as service?

They are not, also their website looks scammy but the prices seem legit and more to the upside than the opposite.

Seems like mining in EU is dying, if not already dead (power cost-related issue for the most part), and not so many Europeans discuss suppliers, EU tax, and all the stuff that are related to EU, unlike how the U.S folks here do, maybe one of you should start a topic dedicated to EU miners so you all can share resources, news and anything else that you might find useful, there are probably at least 5-6 EU based miners around this board.

Would you care to provide proof of payment or some sort of proof that you successfully bought miners from them? They are not affiliated with Bitmain and they always seemed like a scam to me. Sometimes they had better prices than Bitmain themselves.


I'll check with them, they might have something I need.

Regarding Antminer spares.  https://www.antminerdistribution.com/ is EU based and reliable (bougth a miner back in 2019), more expensive then most of asian sites, but if you do your purchase trough a company they will deduct the VAT. They have both miners and spares availble, mostly on request though. I dont know if tare  afiliated with Bitmain, or not.
