Topic: S19 Stop running randomly (Read 373 times)

I'm also in the same boat here with an S19a Pro. Can anyone help me? Here's the current log:

At this point I tend to believe this has to be a problem with the temp sensor on the hash board, however, given we had a similar issue with the 17 series miners whereby the temp sensor issues were 99% of the time caused by a single bad chip, this could also be the problem with the 19 series.

To be sure I would try a different firmware just to make sure the problem isn't software-related.

Boss, I'm in the same situation with 2 x S19a brand new units and extreme noob here 🙋‍♂️, do you have any good info on PIC? Are you referring the firmware?
Any info is greatly appreciated!

dear friends

I have with this problem with 3 others S19pro

after changed PIC this problem showed

My friends, you right , but I tested with 1 hashboard , 2 hashboards and 3 hashboards, all of them have this error
Changed control board with another one, changed pau with another one, changes all fans, but this error is still and Miner can't work more than 1 minute

Just noticed your kernel logs shows that the miner is running only with two hashboard


It seems one of your hashboard is giving you a false signal that leads to this "ERROR_TEMP_TOO_HIGH: over max temp"

What I think is to test the miner with one hashboard but I don't know if it's capable to test it one by one.


Do you have the same unit s19pro?
Try to use the control board from a known working one and let see if the issue is only from hashboards.
If the logs still show the same error after you replace the control board then the issue is in one of your hashboard. You must find that hashboard to remove this error so try to run it one by one to find which hashboard giving you this error.

Thank you friends

I opened it, all heat sinks are safe , I thought may be silicon's may be removed, I pulished every chips with Z9 silicon, but the problem isn't remove

The kernel log clearly states "heat problems" which are usually associated with high room temps, inadequate moving of air, slow fans, dirty heatsinks, and all that basic and common sense things, but sometimes there is more to it than meets the eye.

Can you shake the miner to check if there is anything loose inside? I had an issue with one of my S17 pros, the fans were good, cooling was fine but the miner would show temp error just a minute or two after it starts, it suspected it was a loose heatsink which was the case.

If the board sensors are bad, well... depends what the firmware does with it.


So chip temp 15 is a reason to declare TEMP_TOO_HIGH?

That seems harsh - since immediately before this error message, the kernel log indicates that the measured temperatures are actually below the max thresholds and therefore the 'over max temp' message makes no sense. So perhaps this issues is a little more complex than simply 'too hot'?

Since the measured PCB temp is reported as '0' - perhaps it's a sensor issue?

All fans work correctly in 500cfm
Room is not closed
Air come in and out in best positions
Other S19PRO work in this room correctly,just  this one has problem

I wonder what is the problem with people not reading.

See, it says so in caps, exactly the same as op:

ERROR_TEMP_TOO_HIGH: over max temp

Why do you need others to tell you what your miner is telling you and previous posters even talked at length about?

The S19 needs 500CFM. Else check if your fans are all working correctly.

Its not "just fans", you can't just put the miner in a closed room. When we say 500CFM, that means air coming FROM OUTSIDE to the miner and then again TO OUTSIDE, A/C is irrelevant, move that air!.

I set fans on 100%, but didn't work more than 1 minute.
It's my kernel

Thank you my friend

My room temperature in under 30 centigrade

I update it several times
Try to set fans on 100 percent  and will send you complete kernel log 

Can you post the whole kernel logs let me analyze them for you?

If you have a limit then you can try to paste it here https://pastebin.com/ and then paste the URL here.

What is your room temperature?

If the error on this "stop_mining: over max temp" try to manually set the fan speed to 100 you can find it under miner's settings and set it to normal mode.

If it doesn't solve your issue try to upgrade it first with the latest version available on Bitmain and test it again.

It's work under 2 cooler

that post you just share is full of good information I just saved them and will start pressing the new mining room cause my miners now in my friend house and am planning to move them to mine in the middle of April and this post would help me a lot building a better mining area.

Appreciate your support guys. can't thank you enough.

You can do a split-room setup, check my mini mining farm, I initially had an AC there but it was removed later own and I added more fans both on the intake and the exhaust, this design helps you control dust and noise by trapping all the hot air in one place, make sure you don't have pressure imbalances.

order placed thank you so much sir for your time.

Okay 1 s19 unit expels about 500cfm.

so I think this will do 2 units and put a fan on the end.

https://www.homedepot.com/p/Master-Flow-12-in-x-25-ft-Insulated-Flexible-Duct-R8-Silver-Jacket-F8IFD12X300/202562743

https://www.ebay.com/itm/12-Inch-Inline-Duct-Fan-Vent-Exhaust-Air-Cooled-Hydroponic-Fan-Blower-1200CFM/121181455603?

So 2 tube and 2 fans could pull as much as 2400 cfm out of the room.

Ac >>>>> miners >>>>> tubes >>>>fans>>> outside

himmm the truth sometimes are a dream breaker what should I do with this small room can you help me more how can I exhaust the heat out of this room cause am not planning to stop the mining.

not sure if I'll have big exhaust fans here and will keep the room clean with our dusty summer.

"the summer months are June, July, August and part of September. These months are mostly dry, HOT and dusty! Temperatures exceeding 48c, dust lasting for over a week, all in summer."

NOTE: I like how you miss that click from btu to btc. appreciate your times guys.

regards.

lets say you do not exhaust heat.

each s19 unit is 3300 watts which is about 13200 btu.

so 4 pieces are 52800 btu.

a 1 ton ac is 12000 so if you commingle the ac with the hot air from the miners.

two 2.5 ton ac units can cool 4 s19pros. as they would have 5 x 12000= 60000 cool btu vs the 52800 hot btu.

you have to vent the hot air.   think about the summer heat of 50c or 120f.

only 7200 btu is left from the two 2.5 ton ac units.

am living in Middle East so some how in summer I'll face over 50 degree for sure what am planning to do adding 2 AC's 2.5 ton or 3 ton one would be facing the machines and the other one would be in the back the room is small for the small farm I have it's only 4 S19PRO for now might jump to 8 as maximum later the room size is 4x4msq so cooling it won't be an issue the problems am thinking to face is what if it really need to be exhausting the heat even with the two Ac's running 24/7.

I used to think that I need an AC to cool the miners down where I live, temps go over 40c in the summer, but I came to understand that sufficient airflow is more than enough, you could add an AC (if you don't care about the power bill) but without exhausting the hot air fast enough, you will always run into over temp issues.

Thank you guys I replaced the AC in the room and yes the room was so hot without exhaust and weather where I live is such a hot as hell.

Dude, you are you going to fry these expensive gears, each of these gears costs above $7000 to buy today, and you are torturing them.  


Both miners show PCB temps of 81 where the maximum temp of S19 is just 80, and one or more chips are at 96 degrees Cellius, they shouldn't be close to the max by any means, when the max temp is 95c you should start to worry when the approach 85c, you need better cooling, it seems like you are not exhausting enough hot air and it's going back to the miners, for starters, try 100% fan speed and see how it goes.

it says they are too hot.

so is the room hot.

are the fans set to at least 90%

my board temps are much lower than yours.

46 41   67 67
46 39   69 66   
47 42   70 68

it says you are over 95

hello, I started a mining farm (small one) 4 S19Pros there was 2 of them working good and the other too shows a disconnected still didn't get the reason why?

can anyone help me.

Miner log 1


Miner log 2


the others are keep disconnected.
