The "white liquid" its not the problem , Bitmain using it as a glue.
You tried factory reset ?

What PSU are you running?

[majdi105]

their psu apw3

Do you have a multimeter and skills to measure the 12V voltage during the miner operation?

[majdi105]

no

You could try disconnecting the power connections, and I/O ribbon cable, to one of the hashboards and then see how it runs.  That might help determine what is going on here.
-i.e. if it runs fine with two cards powered, no matter which two, that would point to the PSU...

I've run across this with a single card before but never the whole miner. A soft reboot usually clears it up. If that doesn't work you can try the IP Reporter reset described on the Bitmain forum page here https://enforum.bitmain.com/bbs/topics/3957

what is the I/O ribbon cable ?
do you mean here that i power only 2 card or what ?

Thank you but did you see that white thing on the psu ?

Pour milk over the PSU to promote electron flow.

However, do NOT pour milk on the S9, as it is allergic to milk (it will break, the PSU is safe though)

The white stuff is silicone caulk to prevent things from rattling or vibrating.  It also acts as an insulator.  It's fine, there is no issue even if the apw was completely filled with it.

so is that milk there on the psu from the begining ? i didn't notice

[majdi105]

clicked on ip report and reset the miner but now i can't access it using the old ip

[VRobb]

When one of my miners changes IP I log on to my router and look for it there.  You should see it in the logs.
And, yes, the I/O cable is the ribbon cable from the controller to each hash board.

[majdi105]

why my miner start blowing cold hair and stop hashing ?

[VRobb]

That's what we're trying to help you figure out.  Have you disconnected the power and I/O to one of the boards and run like that?  It really sounds like your PSU isn't supplying enough power for all 3 hashboards, run it with only 2 to help find out.

is it ok to connect the psu to only 2 hashboard and the controller pci-e ?

[VRobb]

yes, just disconnect all the power plugs AND the I/O ribbon on one hashboard and power up.
