(Solved) A921 Error 131073 (HUFAILED)

[s_falahati]

Hey guys,

It's hot here. So hot in fact that some days it reaches 40c temperature and I expect it to become hotter (its late spring yet and summer is coming!) and therefore it's hard to keep miners cold. I have an AC unit installing right now and expect it to become online in the next day or two and hope to be able to decrease the temperature by at least 7c.

Meanwhile; one of my Avalon A921 units shows error 131073 (HUFAILED*) for three of the hash boards and the other one works alright. So here I am asking if anybody had some prior experiment with this error message and if this can be solved. I don't have any idea what HU means but I guess its about temperature. Please feel free to speculate.

Thanks

Does cooling it down and rebooting it make the hash board units work ok again?

In worst case scenario those hash board units are broken because of the extreme temperature in your environment.

Yeah; I already read your post. This error seems similar to the `131072` but I just don't get the description. What is HU that I need to replace?

I will test it in lower temperatures tomorrow since I need to bring it home for further testings and probably tearing apart to replace the HU; whatever it is.

Hash board unit.

Hash board unit.

Thank you HagssFIN. Brought it home and tested it again in the 27c environment and it seemed ok. So it must be thermal paste on 3 of the boards that made them fail hot in 40c; even tho 40c is hot and I know it; still, other miners work alright when downclocked.

Note to myself and others; the error codes are bit flags. So something like 193 is 128 + 64 + 1 and therefore means (in the same order): was too hot before; is too hot now; is idle now

Yes! That's correct.
