You saw the photo of the PCB? as it seems?
according to your experience that definitely have much more knowledge than me, can you tell me what pcb seeing this? what can be the harm?
Topic: A new poll for product warranties Bitmain - page 2. (Read 2698 times)
Perhaps you are part of the 10% of the lucky
Again you make up numbers like the 10 percent. I wish you would remain with true facts not generalizations. I can understand you are not happy with bitmain, had a bad experience. But I suggest sticking to points you can back up with facts, those are what will hold power.
And I might be a lucky one. Or it might have something to do with treating all my miners nice. During summer I pumped tons of CFM though them to get hot air out. I successfully mined all summer with no problems (other then 1 c1 board).
Now I'm waiting for arrives pcb I bought from Tupsu, when comes the mount, and see what happens
this and the pcb, and the other is mounted on the miners, but is off, is disconnected, equal to this
U101
do you think you can fix the pcb?
What burns normally?

I have no information about the chip, but I assure you that are built with poor materials,

I just am not sure as look at the gekko science compac - https://bitcointalksearch.org/topic/gekkoscience-compac-bm1384-stickminer-official-support-thread-1173963 . It runs a BM chip and is rock solid. I have been putting them through overclocks, and sidehack and novak did an insane OC. So I don't think we can say the chips are cheap material they do work. I mention this miner just as I have had so much fun playing with it.
They do normally preform to spec on their chips. Their S7 was not good for them on this. They now have two batches next as some did under-preform but on first batches sometimes that does happen.
I have had a LOT of mining gear and only 1 bad blade from Bitmain. It was a C1 after a few months. So I guess my experience is just a little happier/better then what yours has been.
I'm not saying your not valid. Or that I'm right great quality. Just that you really cannot lump all chips together.
I have no information about the chip, but I assure you that are built with poor materials,
I can understand that in the first batch which is bad, but they do not in any lot.
have you ever wondered why bitmain like many Chinese only give 90 days warranty? do you really think that Chinese policy? in everything you buy of any material guarantee is 24 months or 12 months. 90 days does not exist in any part of the world.
all users who bought S5 had PCB faulty, or burned, regardless if they have the frequency 350, or 400 ,.
tries to open a poll, and see how many people have pcb not working.
few are the people who have been lucky not to have problems, 10% without problems, and 90% defective material.
that's why I say that the material of the chip is poor and cheap.
looks at the power that sells bitmain, as ever with that gives you 365 warranty?
and the miner 90?
listens to the problem is not the guarantee, the problem is that if a user after his warranty is over, must have the possibility (paying) to buy new spare parts. at least for 24 months you can find spare parts (new) is not used as bitmain, who sent pcb used.
I do not understand you it seems that you agree that if you break your miner, for failure to take the chip and set aside

I asked to buy bitmain 2 blades, was paying them because my miners have five months, and are out of warranty, but bitmain told me that no longer produce pcb S5, and I had to look on amazon or ebay.
a response of shit,
And I repeat to say, chips are built with poor material, that's why they are cheap.
Now I bought a used PCB, from Tupsu, a user of the forum here, I'm waiting for is that I get.

Can you link to anything to support chips are of poor quality? Just seems like a big accusation. It seems like other things could fry a board that chips can't be a catch all.
Where are you getting info on chip material?

But if the problem is a blade or two and you need to ship back the whole thing? Might be okay for a 1700$ miner, but for a 100$ miner? Not so much imo. Or a 250$ S5 might still not be worth the 100$ shipping. Then again probably none of these miners are still under warranty, but still, what if its a small U3? Shipping back is probably the same as buying a new one.

Are you sure they don't allow shipping blades back? I know they have tightened warranty some. But I would think shipment of bad blades is still allowed.
I could be wrong though as been a while since dealing with a bitmain RMA. Are they really making you ship the entire unit when you know for sure it it's a hashing blade?
Well again, i guess i'm biased. I didn't do it myself, but heres the story;
The half working antminer S5 i bought, previously had to be shipped in it entirety to Bitmain because of one bad blade. Then later on he received it back and it was missing the black metal bracket thing you screw the controller in and then into the heatsink that hold the controller in place and prevent the miner from being wobbly.
And no part had been replaced, the dead PCB was still dead.
So i can try to not be biased and call Bitmain incompetent for this, but the fact still remain its easy to assume that you're required to send the whole miner back. And to be fair, in the best case scenario, you still had to pay for RMA, which isin't really what you'd want from hardware on warranty.

Well there shouldn't be that many miner breaking down and needing to be replaced, but if so then yes. They need to be able to fulfill their warranty anyways, and having miners offline on shelves waiting to be used as replacement for buyers isint really good because its wasted value.
So they should mine with them. People would get used part replacement but then you're sure they're working right.
From what i understand right now, Bitmain have you ship back your miner and they try to fix it, then ship it back, sometime they mess up and forget parts and do not fix it. Overall its a pretty abysmal quality of service.

The problem with this is people who have had bad luck on their returns stick out and get much more attention. As humans less people go on forums and say thanks for X RMA. But if problem very good chance it goes to board.
I have had good experience's with bitmain. I was out of warranty period on S3 needed a controller that was not brick I paid them for it and they shipped it quickly to me. Now the C1 was syscooling but yes I had horrible experience there.
And I'm not a suck up on bitmain. But i think they are getting a bad wrap. No doubt some of the stories we hear they deserve it. But the stories we don't hear and the machines that keep working they don't get the credit for those.
I'm sure this is not what people want to hear or know. If anything they are getting more tightened on warranty. Look at S5+ they shipped with every unit and sent paper - https://bitmain.zendesk.com/hc/en-us/articles/206312085-New-S5-Hong-Kong-China-Warranty- . Basically if you want to modify it and do not get permission you broke warranty. If you use 2 instead of 3 PCIe you break warranty. The list goes on. But I think they will get more tightened if current continues, and not go the way of more day's and better RMA.
Well i hope so, but i can't see RMA/customer service being proper for returns when the only way to get it replaced if its broken is usually sending the part back if under warranty, which may cost as much as just buying a replacement part? Hence its not really a warranty if you need to pay for it?
And yeah i guess i shouldn't place my opinion based on what i hear, but i think the aforementioned issue is objectively based.
My S3 was out of warranty they did me a favor of selling me one. If it was in warranty I would have shipped back and got new one through RMA process.
Sending back the part would have been cheaper then what I paid. I think it was like 35-40 dollars. So if in warranty you could have shipped controller in for less then that.

Best of luck on this adventure. It seems a lot like when the Indiana legislature wanted define the value of Pi to make math easier, decades ago.
This happens because the chips are built with poor materials, which is why we have many errors, and many burned pcb

Bitmain could still have a better replacement system. For instance they can and they do run the "outdated hardware" in their own mines for an extended period of time. We know that they keep some, since we know they still have some S2's. Since they can ship them out. So they could easily have a portion of the miners alloted to stripping down for parts when needed. For instance if its within the 3 month garante, you could maybe send a picture proof and get a replacement shipped.
Some farms operated by Bitmain are owned by third parties, like the S2 farm that was advertised. With a finite amount of space they don't necessarily hold sufficient stock of older miners.Also it would long term kill the farm's. It's hard to tell but most likely there is a piece that is most returned. If they kept pulling from miners even a few a day this would really add up.
Imagine a farm with miners sitting on shelfs waiting to be parted out. Just does not make sense. I do agree it would be nice if they made some things in quantity they have long after warranty. But as a business I cannot expect them to keep stock forever in a industry that moves so fast.
And asking to go from 90 to 1 year is just a lot. If you wanted more reasonable find some reason that 4-5 months is needed over 3. If you can find a reason X part craps out every... or some justification that is good enough to warrant them moving it. Unless we have some good justification then we want better I don't see it happening.
