How reliable is the AntMiner S19 Pro?

[Gabrics]

It really depends. On the version on the subversion on the area you are in (humid and hot or cold), etc.

Hello,
I noticed it too, I've been mining in a sort of fairly humid cellar since 2015 and it's a disaster.

I have used at least one model from each family S1,S3,S5,S7,S9,S11,S17 and S19 and recently s19Hydro). If we ignore the S1 and S3 which were rather robust, the reliability of Bitmain products is generally quite catastrophic even if we can sometimes come across a less bad series.

There are, among other things, oxidation problems, but there are also unacceptable problems for a company that has been manufacturing miners for 10 years. I understand that the calculation chips are fragile, because they are pushed to the limit, but that auxiliary DC/DC converters fail on almost all models since the S7, that's not normal.

Until now I have always used Bitmain because the commercial service is good for me who is in Europe (nice delivery, payment in BTC...), but the reliability is not going up.

Personally, I work in electronics and in my job we have never had problems of this type. There are times when I wonder how they manage to have such low quality. The hardware seems designed by amateurs, the control of the fans which spend their time speeding up and slowing down, causing very harmful thermal variations to the welds, I also wonder about the quality of the software...
 
I recently bought an S19 hydro model to test, hoping that it would be better because there is no fan so no vibrations, no dust..., I already have a hashboard broken after two months. I'm fed up, I'm wasting my time fixing this shit. I have my free electricity (hydraulic) but I barely earn any money anymore, the earnings struggle to cover the purchase of the machines, I think I'm going to give up mining.

I've serviced and repaired an number of S17's over the past year or so, I have to say that their soldering quality leaves a whole lot to be desired.

If the S19 and later products are built to the same standards, its hardly a surprise that they fail.

Their boards are riddled with soldering issues, I guess they're built to the lowest cost possible.

As for regulator fails, I've only seen a couple and both were soldering issues again, most of the time its either transport damage and broken joints or ASIC's damaged due to the poor heatsink design on the 17's.

I would have expected the Hydro's to have been better, simply due to the arrangement of the heatsink assembly.

Its a shame really, their ASIC design is good with the exception of the IC package choice, they are subject to moisture ingress. I have to bake replacement parts for at least 48 hours before use to be sure they survive the soldering process.

If you say you're having issues in humid areas, this doesn't surprise me.

Thank you for this information, I suspected it because I noticed that some failures occur after a restart following a long period of shutdown. Now as soon as I stop the miners, I try to store them in a dry place.

I also noticed that very often a miner crashes due to internet instability. I think that internet network instability must reveal bugs in the miner's software. Since the software also manages cooling, it can turn off the fans while the hashboard is still working... I think I've had cases like that on S9s.

I had an S17 but it died pretty quickly.

The S19s were a little better. out of 4 I still have 3 operational.   

In the case of the S19 Hydro, it disgusted me so much that I haven't looked at it yet, but it fails during operation, just after a network outage that lasted a few minutes. it doesn't come from humidity. I will keep you informed.
