M3X Hashboard Problem

[kalstr]

Hello,

Today one of hashboard M3X is not working, status of device is Alive but GHSav is 0.00..
First when it was not working with one restart it started again but now its not.

Also hashboard is hot, frequeency(avg) is 192, EffectiveChips 0, Temp1 32.00, Temp2 0.00

When an hashboard is dead, will it be "Dead" status?
Contacted seller and he told me is connect loose so I must re-plug control board but still is not working.

Please if someone can help me, I will really appreciate it. Please let me know if is needed more info!

Have you tried to reset the miner?

Try this method hold the IP reporter/reset button for 15-20 seconds then after that access the IP again and set the pool properly make sure no extra character or space.  Then test it again.

Also try swapping board positions. Be careful when handling MicroBT devices, as they can be quite delicate. I don't know if the M3x also uses the (data) "connection bridge" as the M10...

I have done it multiple times but same issue.

Link does not help. I have clean up all hashboards and PSU also and same thing.

This issue happened 3-4 weeks ago but after cleansing, the board started working.

Also try swapping board positions. Be careful when handling MicroBT devices, as they can be quite delicate. I don't know if the M3x also uses the (data) "connection bridge" as the M10...

I swapped, before was SM1 with problem and now is SM2 so it's hashboard fault not control board or something. But it doesn't result as "Dead" in Status and board is hot.

Good, also try using it alone, without the other boards, and see if it makes any difference. You can try swapping positions maybe it works best in one of them.

Or, the fact that you are manipulating the data and power connection points is making the difference (ie, making better contact). Again, be extra careful.

I swapped to SM0/1/2 it was 0 ghsav. I tried it alone still same issue. Removed it and added other boards, other boards started working normally.

I have another M3X, can I try with that one or its dead?

Put it on eBay or marketplace on this site.

Sell it as a dead hashboard for repair.

Stop spending time on it and move on.

It simply is not that valuable to try to fix it.

You would need to take a good board and the bad board.

And use meters to test each board at many points. If you got lucky you may find the bad solder joint.

If it is a bad solder joint.

You may find a bad capacitor

If it is a bad capacitor

You may find a bad resistor
If it is a bad resistor.

You may be able to solder and fix any of the above.
You may be able to replace a cap or a resistor.

But if it is a bad asic chip with a dead short it is next to impossible to repair it.

Thank you for the help

Miner restarted automatically and all hashboards started working. It's a connect loose but I don't know how to deal with it!

Sounds like the infamous data bridge issue philipma1957 recently experienced and had so much fun diagnosing. Assuming the M3s and the M10s share that.

Hello,

What is data bridge in hashboard?
Is this one https://pangolinminer.com/product/miner-hashboard-connect-cable-m3-m3x/ ?

Not exactly, in the M10 that cable is replaced by a small PCB that serves the same function.
That said, try swapping one end of 2 cables to different boards or on the controller end, different sockets. Does the problem follow the swap?

Already swapped hashboards and had same issue. Its a connect loose for sure, M3X's are unstable and restarts randomly for some reasons when it restarts there is a low chance that hashboard will work. Have been 2 days without working and today it restarted and started working, giving same ths like other boards.

Connect cable is stuck and cannot be removed.

Yeah they have three separate cables.

It could be a bad cable.

But if it can not be removed you can’t put a new one in its place.
