Im having identical issues. I own 2x T17+ units ( 2-3 months old ), and i am having issues with temp sensors.

Try using Asic.to firmware and undervolt or overvolt it a bit. That seemed to be a fix in most instances. Also, if that does not work, try lower frequency with higher voltage.

Im having identical issues. I own 2x T17+ units ( 2-3 months old ), and i am having issues with temp sensors.

One T17+ machine just dropped a temp sensor on 1 chain:

Code:

[2020/04/21 04:11:04] INFO: chain[0] - Shutting down the chain

I tried re-flashing with every possible firmware and issue persisted. Asic.to and Awesome miner firmwares helped me a lot since they auto restart on unbalance. So i usually let it run with 2 boards, however sometimes the third board re-appears but this time some of the chips have an X on them: https://prntscr.com/s5qm51 but im fine with this as long as it stays like this at least.

The 2nd T17+ machine - i tough i broke it. I was frustrated that my first T17+ machine is working at 2/3 of power so i decided to up-clock the other machine that was fully operational. But right after the tuning process, 2 sensors on the chain started dropping.

Code:

As the machine was using Awesome miner firmware, which requires at least 1 sensor our of 4 to be operational i was confused why did the board drop? I contacted support and they are currently investigating this.

But then issue became worse:

Code:

It now appeared that chips were dead on some boards. I tried switching slots and data cables, all pointed out to 2 dead boards. And this morning i was planning to open the machine and visually inspect if the chips were burnt and guess what? They re-appeared by themselves.

Code:

[2020/04/25 11:31:15] INFO: chain[2] - Initializing
[2020/04/25 11:31:15] INFO: chain[1] - Initializing

[2020/04/25 11:31:30] INFO: chain[0] - 44 chips detected

However some of the chips have an X: https://prntscr.com/s5qp07

But still better then 1 board.

I also contacted Bitmain regarding temp sensors issue, they have told me to ship it back to China ( Europe office is closed due to pandemic ). I have decided to keep the half-working machines as shipping cost + possible complications were not worth it. If i encounter any more issues i will post it here. The post above that said he used to warm up the chips sounds interesting. I will give it a try if boards start dropping again.

T17e machine works fine for now.

I recently purchased a dead S17. the previous owner said this machine experienced problems with dropping hashboards right out of the box.

He RMA back to Bitmain. He eventually got it back, but only 2 hashbords were working. Eventually the other 2 went later on. I paid scrap value for it.

I changed out the data cables, re-flashed it, took it apart, tightened some connections, played with grounding, etc...

The log shows:

hashboard 0 has 0/48 chips detected
hashboard 1 has 40/48 chips detected
hashboard 2 has 32/48 chips detected

Shuts them all down.

I've been able to get 2 boards working by heating up the unit on startup. I basically put another miner's exhaust on the intake, and block the exhaust fans and get the unit very hot. Once it starts hashing i unblock the fans and remove from heat.

Seems like the boards are very sensitive to temperature on startup, so it may be worth trying if you have bricked units. it just frustrating because sometimes they work fine, and when i reboot they are dead again unless i do my startup procedure.

Now its running 2 of the boards, but randomly the second one drops out do to the temperature sensor issue.

This is good info. I have one of this missing a board units.

It worked for 26 days and now the one board is fuck you.

I will still be under warranty on may 15 which is the ½ ing I may send it in then.

He MUST create a repair ticket and only send the miner when instructed, he should also send the WHOLE miner and not just the bad hash boards, and if they don't receive it within 30 days from the day THEY shipped it from china, it will not be treated as DOA, if he sends it before 30 days have past - hey can still get paid for the shipping fees in the form of a coupon, so you want to make sure to use the fastest shipping method possible and not exceed the 30 days period if you want to be compensated for the shipping fees.

A new miner (T17+) only hashes on two boards out of three directly from the box.
Pure thievery as it would cost more to send it back than to keep hashing on two boards.

Not pleased.
DO NOT order T17+

They have RMA facility at "4704 Roseville Road, Suite 108, north highlands CA 95660". USPS should not be to expensive. Here you have more addresses you can ship to: https://support.bitmain.com/hc/en-us/articles/220138027-Global-repair-site-delivery-addresses.

Glad to hear about your wife's health improvements.

As for the 33% refund I'd say it's highly unlikely, Bitmain has very weird "scamy" rules regarding DOA and warranty, if you claim that this was DOA, then they will say that 30 days have passed from the day they shipped the miner, assuming shipping from China takes 10 days, you have only 20 days to act, if you take more than 20 days to send it then it can't be treated as DOA anymore, so even if for some reason DHL, FedEx or whoever your courier may be fails to deliver the miner under 30 days, and say you get it 31 days after it's shipped, and it arrives dead, Bitmain will refuse to treat it as such because their rule states the following:

Quote

Please ship back them within 30 days from Order Ship out date, otherwise, the devices cannot be treated as DOA.

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, but Bitmain reserves all the right to tell you that YOU were the one who toasted the board and that they owe you nothing.

Bitmain warranty is a joke, they know that most people will rather keep a half-working miner than waste time returning it and wait for the replacement to arrive due to the nature of mining where time = money.

Having said that, I noticed that being persistent can sometimes (actually seldom) grant you some sort of compensation (in a form of coupon/s) without having to send the whole miner nor the defective part. That of course, depends heavily on your purchase history and the mood of whoever is handling your case Grin

same issue for me. and shipping it back is pretty senseless as ½ ing is coming.

It is a PayPal purchase I am under 40 days. I wonder if I ask for a 33% refund if I can get it.

I have not pushed very hard on this issue with bitmain as my wife has been sick for 70+ days

Since Dec 29 2019.

I have had a lot more important things to do. THEN TO FIGHT OVER 1 HASH BOARD.

BUT I think doctors have finally figured out my wife health issues and have a treatment plan that is working.

I may pursue a 33% refund on the t17+

I will post back on this idea on Monday the 16th of March.

That is correct, straight out of the box, installed on a good voltage regulator of 220v so this rules out any power related issues, there does not seem to be any physical damage from DHL shipping so this in a nutshell is a faulty control bored.

I will still mess with it to find out what's wrong and why isn't any lights coming up, that will take sometime but i will post my findings.

I did order a new one and it ships whiting 20 days so i might end up with at least a month of an expensive gear sitting there doing pretty nothing but loses value.

So new miner with a brick for a control board.

And it never worked. At all correct.

The PSU works just fine, PSU fans spin the way they are supposed to, however, no lights coming out of the control board, the miner's fan do not spin.

an update on the quoted issue, trying another known to work PSU did not solve the problem, trying a different control board fixed the problem and all hash boards work just fine.

This is probably the first time ever that I receive a miner with a faulty control board, what I am going to do now is order a new control board for the S17+ and then start "my war" against Bitmain, it makes no sense to delay the order to wait for them to respond to my complaints. the board costs about 100$ shipped, negotiating with Bitmain will take forever and chances are not high enough.

When I have the chance, I will try to inspect the control board and try to figure out what's wrong with it, will keep updating the situation.

Umm.. is Bitmain only accept S17s for RMA? All of the other options for all other miner types dissapeered. Can someone please verify? Is it only me?

The problem is both Asic.to aka Taserz as well as AwesomeMiner have not released anything for the T17+ yet, so you can't undervolt that middle board, therefore I would set all fans at static speed of 100% for now, T17+'s hash board costs more than a large box full of those 12mm fans, so I would risk the fans but not the board.

Hi , if you need more speed by easy mod, just unplug blue wire on each fan if you want for fix it at full speed Wink

yeah when I go back up to clifton i will try this.

'The right to privacy matters'

my t17+ has a hot middle board.

it goes to 86 on one chip and the board shuts off.

the fans never ramp up past 3900-4100

i would think if fans went to 4800 i would be good.

also 1 speed not 2 speeds.

would be nice to have a lower speed.

or faster fans.

i will need to figure a way to save that board.

Here is another case I would like to add, I bought 2 S17s+ 67th, brand new ordered from Bitmain, I am overseas at the moment so I had someone receive and install them, the first gear worked just fine, started hashing right away, but the second one did not turn on.

The PSU works just fine, PSU fans spin the way they are supposed to, however, no lights coming out of the control board, the miner's fan do not spin.

At first, we suspected a PSU-Control Board connection problem, so I asked him to check the wires and everything seems to be in place, he had to leave before he could troubleshoot any further, so probably tomorrow. What I suspect is the PSU, there is a tiny chance that the control board might be bad, but that is unlikely, how often do you hear someone complain about a control board compared to PSU?

Anyway, I will keep you guys updated, unfortunately I can't send the gear back to them, so whatever the problem may be, I have to fix it on my own, I will of course "bother" them every day with emails until I get tried or they compensate me (whichever comes first).

Which machines are you running? Are their flagship S17s also experiencing this problem?

S9s don't have this game-over problem with sensor errors in later firmware... wtf is up with bitmain, they are literally creating problems for miners.

Adding a fourth problem:

Code:

2020-02-02 15:38:53 power_api.c:91:get_average_voltage: error: total_chain get 0 !!
2020-02-02 15:38:53 power_api.c:109:check_voltage: target_vol = 17.90, actural_vol = 0.00, more than 0.5v diff.
2020-02-02 15:38:54 driver-btm-api.c:141:stop_mining: stop mining: power set failed!

2020-02-02 15:38:54 driver-btm-api.c:127:killall_hashboard: ****power off hashboard****

Remedy is to reboot the machine remotely, thus far.
