Topic: Chip running hot on Avalon 1166 Pro 81TH (Read 348 times)

Have you tried to exhaust the hot air from your miner or the room is closed?
If it closed room without exhausting the hot air out properly then the hot air just circulates inside the room which can lead to this miner being very hot.

You better do some ways to cool down the miner a bit by running the miner at normal mode instead of high-performance mode.
Try to clean and remove dust from the miner it also helps to cool the miner a bit.

Same issue but little different i guess

Avalon 81th miner
Sometimes it gives complete 80th hashrate and runs for longer time without issue . But sometimes it gives 50-60th for 2-3min and then decrease the hashrate and restart every 4-5 mins .

If anyone knows the solution then please let me know

Actually, I also read the description logs what are those logs are and I just use them as notes on reading logs. But the logs from ferjacon seems new logs on the first run and get those hardware errors that is why I suspected something bad on the middle board.

Under your API logs, you get higher numbers meaning there is a hardware error the middle hashboard gets more hashboard faults. It could be ASIC chip overheating it's your old issue if your miner right now is running stable and hashing you don't need to be a worry.

If you want to get other meaning of those logs I suggest you check the thread created by HagssFIN you can find it from this link below and learn how to troubleshoot

Out of curiosity, would it be possible to explain what these numbers mean?

In the log description it says "How many calculation fault of each hashboard" and goes on to mention a normal number being smaller than 2/10000.

My numbers are much higher MH[1461 2024 807] HW[4292] DH[2.006%].

Have you tried to flash it with the latest version?
If not try it first because all of their latest firmware from Canaan has fan optimization so maybe your miner still running with older firmware?

Look at these logs MH[0 2 0] HW[2] DH[39.252%] it shows the issue on the middle hashboard and maybe it's due to overheating.

I'm having the same problem with Avalon miner 1166Pro-81.

In my case is Hash0 wich "runs" at low temp. Hash0 it's alive but is seems not to work (i cheched with the power consumption) After 5min that the asic starts, the temp in hash1 and hash2 goes up.

Log after 5 mins

I tried with the solution posted and partily solved the problem fixing the fans speed at 55% with a command via FMS soft, and the temp in the others Hash manteins in the recomnded limits, but is not permanet solution because if you rebbot the changes are lost.

[{"command":"ascset","parameter":"0,fan-spd,55"}]
FMS download link: https://canaan.io/service/447

If someone knows how to try to fix the problem I'll be gratefull.

Great,

I will continue to run it like this then.

Thank you very much for the help everyone

No those numbers are not volts but it counts in mV or Millivolts if you have a multitester you can read most of the chips even on Bitmains machines it's around Millivolts of each chip.

So it should be 349mV or 0.349V


That's good that you can manually set the fan speed but never heard that you can manually set the fan speed through the FMS tool.
Anyway, about the numbers under that voltage, it's a normal number because you are running the miner at workmode[1] or high-performance mode if you set it to normal mode those voltages will drop too.

Well your temps are all good. your voltage went from 344 to 349 since I do not know what the number means ( it does not mean 349 volts  ) I can only say it is 1.5% higher than the older 344  number. Your temps are really much better. can you read the watts for the whole unit?

So I found out through Canaan support, that you can adjust the Avalon fans manually in the FMS software under diagnostics, using this command:

[{"command":"ascset","parameter":"0,fan-spd,100"}]

I put the fans at 50% running at 4000 RPM and it made a huge difference with the temperatures.

The voltage is now at 349 though, is that too high? or is the miner safe to just let it run like this?

This is what the log is showing currently:

But the API log itself shows high temp

So the only problem is there is something issue in your fan or like the above said maybe the firmware itself.

Even it's up to date it's still recommended to flash it again to make sure to fix all possible firmware corruption or to refresh your miner.
You can download the firmware of this unit here https://download.canaan-creative.com/

Interesting,

I will see what I can do / unplug and re-plug the fans.

Also, I am blowing cold winter air from outside, is it possible that the miner thinks it's cool enough and not making the fans run faster? The ambient Temp shows up as 23 and the room temp is around 17 degrees Celsius.

Firmware is up to date I believe.

Thank you for the replies

Maybe ask Canaan about it?

It could also be a software bug, which is maybe fixed in a newer version software.

Unfortunately with the Avalon 10-11-12 series there is no "More Options"-field like there was with previous generations, so you can't force your own cgminer attributes, for example for manual fan speed.

Those values from your chip temp are overtemperature it can kill ASIC chips.

It seems there is an issue with your fan speed its running very slow look


It should be around 6000 RPM and FanR should be higher than 75% but mostly it's running around 90%

I don't know if you can manually set the fan speed to higher but I couldn't find it under their manual documentation.
Would you mind it to try replugging all fans and maybe it can fix this issue?

Hello,

I just had a few questions regarding the Max chip temperature for the Avalon 1166 Pro 81TH.
In the manual it mentions to keep TMax below 85 degrees.

However the first chip on my miner seems to be running hot with a TMax temp of 89, the other 2 chips are perfectly fine (below 83).

What could be the reasons for this? will this damage my miner even if average temps are good?

Also, the Hardware Errors seem a bit high as well, or are all these numbers withing a normal range?


Here is part of the log for reference:
