S17+ "read temp sensor failed"

[xbtx]

Hey guys

So, one of my S17+'s started having this error today, one of the hashboards disappeared and the fans slowed down.

Here's the log:

I've tried rebooting and upgrading the stock FW, but to no avail.
Any ideas how to workaround this?


Thanks!

This is caused by physical damage, there isn't much you can do to fix it if you don't have the tools and the skills needed.

Notice while the kernel log reports an issue with the temp sensor, this problem is rarely caused by an actual faulty temp sensor, it's usually caused by a bad chip on the hash board the reports the error, in your case chain 2.

Sometimes, the PSU can be the cause, to test this, unplug the other two hash boards and see if this one works, if it does not, then it's not a PSU-related issue and you will have to unplug that hash board and mine with 2 of them.

By the way, this is a very common issue with all the 17 series, at this point probably the vast majority of these miners have lost at least one hash board.

thank you for the quick reply. I've searched and saw some other people with this error that apparently fixed it with another FW or reflashing the FW? Or do my logs change from those?

How do I spot the physical hashboard with chain 2?

Thanks!

You have not posted the other logs so I can't tell, however, very rarely the temp sensor error is actually a temp sensor error, in that case, some custom firmware will work as long as 2 out of 4 sensors are working unlike the stock firmware which requires 4 out of 4, but this isn't usual, however, you lose nothing if you try another firmware like Vnish or BO.

How do I spot the physical hashboard with chain 2?

Follow the ribbon cable end at the control board, there are some tiny but readable labels of Chain numbers.
