Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
⭐ Merited by frodocooper (2)
Hey guys.
Some info i just found out.
I managed to get all 3 boards to work on one of my miners ( with some of chips getting X tho after couple of minutes of mining, total hashrate ends up at 50 TH/s instead of 60 TH/s ) by placing a miner at tilted at 45 degrees with one side being set on the wall next to it.
Also the 2nd miner works only with 1 board but only if placed on its PSU.
So if your boards are failing you can always try different angles to get them back to life. Worth a try, hopefully it will work with your gear as well.

For clarification: 1 by 1 means when i receive 1 USDT i send 1 coupon. In case anyone is concerned about being scammed.
i do have more coupons but they are expiring soon "1. The coupons will expire at December 31st 23:59:59, 2020 (GMT+8)."
i have 1$ x50 of those. They say they are for S17 and T17 series. But when placing an order for current S19 series system accepts them ( initial accept, havent proceeded to checkout yet ).

you will at least manage to get some refund in the end.
When you said some refund i wasn't thinking about value equal to 2 large pizza-s and a coca cola. And the value is in COUPON. Not only that they don't have anything for sale for months but also why would i even consider buying from them again.
Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
Man i wish i could bring any good news but i submitted all documentation, was polite, sent tons of e-mails, told them that we had 3k+ usd in expenses due to fail equipment and 300+ USD in expenses due to DOA returned units.
And you know what their response was?
"we double checked with our leader we can apply for 23USD coupon for you " IS THIS A JOKE?
And then guess what, they doubled it:
"sorry what we can max compensate is 50 usd "
This has to be a joke? Jessica L. is bored and she-s joking with me.

Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
Well nothing much really, but at this point i have nothing to lose. Returned them 2 units, 2 units came back. Both died within few hours. Again sent them 1 of them, i decided to keep one that works somehow with 2 boards, and the last one came in also malfunctioning ( works with 1 board ). I still can send it back for repair once again but whats the point? They will always send scrap back and that is obvious. I can also include some international authorities, i mean they can't just get away with this that easily by producing and selling scrap.
I just need some agencies, local or international. But the thing is i know that they can always say that they sent out a working replacement and that it died during transport and we can't do anything about it. If they wanted to find a solution they would, but they don't want. Its much cheaper for them to pretend that they are fixing units until the end of the warranty period.

Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
Does anyone know any e-mail / website for local authorities in China? Bitmain is sending me DOA units from repair all the time. And now one unit is 2nd DOA. Really not fair from their side, i am paying all shipping and everything so we can bounce back and forward scrap units. And their coupons mean nothing at this point as not only that they dont have anything else for sale but it is questionable that i will even consider ordering anything from them again.

but anyone that understands the 'bathtub curve' will know that if a new piece of equipment is going to fail, it is most likely to do so very shortly after powering up (e.g. within a few hours).
My brand new units:
2 T17+ died within 2 months.
1 T17e died within 6 months.
And as for the environmental temperatures it all happened during the winter so no worries on that side. I wish you good luck with those honestly.
Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
Ok so i decided to re-solder chips, however instead of going for every single chip i want to start with one that is already faulty. Does anyone know a way i can determine which one is it if there are no visible damages on the board? I want to gather all required information before i dissamble the miner.
@The_binary_Observer we need your expertise on this one.

you could threaten them with a legal action for sending broken machines as "new ones" and then failing to repair them,
I can't as terms from Bitmain say:
1.6 Replacement Product or replacement product means the Product of the same type or specifications provided to replace the defective Product or Product of the same brand with hash rates no less than that of the defective Product. Replacement Product may not be a new Product. The warranty period of the Replacement Product will be the remaining warranty period of the original Product calculated from the date of dispatch of the original Product, except when the warranty is voided in accordance with the terms and conditions of this Policy.
https://service.bitmain.com/support/terms
As for the state of miners, they are not oily, they are dusty. I can show pictures if anyone is interested.
Regarding the first one T17e that dropped 1 board out of warranty - i think im gonna wait for it to drop more boards. But as i said whats the point in repairing if they are sending same crap back.
I have made 2 proposals to Bitmain so far:
1) We send you DOA units, you replace with new series once available ( we can pay difference in value )
2) We send or keep DOA units, you provide with coupons for new series once available. We expect coupon not to be below 60-70% of what we payed for 3 units, T17e 2x T17+.
This seem fair and logical instead of sending crappy gear back and forward. Also we are risking our company to get fined for up to 10.000 USD because importing scrap equipment is against the law.

Here is the update on my situation.
T17e ordered, worked for 6-7 months. Dropped a board recently - out of warranty - will try to resolder chips as explained in this thread once i gather all knowledge and material.
2x T17+ - dropped almost all boards after 2 months of operation, sent to Netherlands for repair, shortly after we received info that replacement units have been sent out from China.
After 20 days of trouble with customs, we finally managed to get them in our possession. Customs inspected units and concluded that it were used ones and not new ones and asked for statement that we are importing operational units and not scrap (importing scrap is against the law). Both units were really dirty on 1 side, like it was stored in some warehouse for 3 years, i haven't inspected the inside but fans appeared to be clean. Its not just regular dust you can wipe it out, this appeared like it was glued to the miner. You could scratch it out only. Bitmain sent out replacement units within 2 days of receiving ours, and units arrived in our country in less then 2 days via DHL, so that was fast, but our customs delayed it a lot. Also one thing to notice is that Bitmain extended our warranty period for 18 days.
Shipping didn't cost us very much. I think total will be 80$ for shipping, and about 62$ for customs (for both units total). But the trouble we went trough has no price. Since we ordered as company we needed to provide a total of 12-17 documents ( statements, invoices, confirmations etc etc ) regarding export and import.
So, i was aware that Bitmain sent out same crappy gear and that it is just a matter of time before same issue re-occurs. I plugged in both miners. Both worked fine but then...
After 5 minutes = 1 miner dropped a board.
After 4 hours of mining = the other miner dropped 2 boards.
So conclusion is, replacement units were DOA, One miner works with 1 board, the other one works with 2 boards ( for now ). Both miners have exact same issue ( temp sensors ). I have contacted Bitmain and they told me to try and replace firmware
and if that didn't work they suggested me to send them again for repair but this time they will provide me with coupons for shipping fees. I don't mind sending the units back again for repair, but whats the point if we are going to bounce back-and forward this shitty gear until warranty expires.

Wait was it a DOA ( dead on arrival ) ? Or did they work for some-time?
Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
[...]
So chip / heatsink issue on most of units, and yet Bitmain claims if heatsink is loose or chip is burned that warranty for that board is voided, so sad.
Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
If you can find new sensors and know how to replace them you can try that. If machine is still under warranty i would suggest you to just return it for repair.
Switching to Asic.to or Awesome miner firmware can help a little in some cases. By upclocking the boards, the machine runs on higher temp which causes less temp sensor errors. Also you can set miner to automatically reboot after board drops.

Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
1 question to those who have sent units back to Bitmain for repair:
Can i switch the hash-boards from another machine? Both machines are at warranty, however one works with 2/3 and the other with 1/3 boards.
I am thinking to combine the non-working ones into the same unit and send them for repair. Do you think that this is possible? Can they even tell the difference?

If you decide to go for RMA, on all the new models you MUST ship the WHOLE miner, you might get lucky enough to be asked to ship only the bad part such as a hash board
I asked them if i could send only the hash boards. Here is their response:
"If the hashboard is sent separately, the whole machine can not be debugged. It is possible that the repaired hashboard can still not be used after being installed. The warranty will be lost if the hashboard is sent separately, If you accept this risk, you can send it separately"
it is because at some point the machine was exposed to high temperatures, damaging the temperature sensor
This could actually be true. My 2nd T17+ got broken a minute after i tried to overclock it. Worked fine for 2 months before that. So please do not go over 800 Mhz on default cooling.
but is it also possible that if one fails it will send incorrect information to the other 3? I don't know, as I mentioned before I have no technical knowledge of electronics and I don't know if this is possible.
It is possible if 1 chip fails then the whole chain fails. Also if your machine works normally in cooler hours of the day, try lowering the frequency.
Re: T17/S17 malfunction: cases, solutions, remedies, RMA history
I have succeeded to get the 2nd board operational by heating up the machine ( previously he saw 40 of 44 chips and when heated 44/44 ). But it was just a matter of time before it dropped out again. I found out that you can do the same thing with his original paper box if miner can see at least 1 board. ( upclock board, cover with a box, let it run for 10s, unplug from wall socket, re-plug again ).
On the other machine i found the best solution to be the following:
On the other machine i found the best solution to be the following:
- Machine usually works with 2/3 boards only.
- Up-clock the unit to 800 Mhz.
- Set Disable chips at 92 C.
- Set the unit to downscale if chip overheat.
- Quiet fan mode at startup.
- After it restarts all 3 hashboards are visible ( for a 12hr or a day ).
- Up-clock to 800mhz again but select Pre-save option this time.
