Any ideas what might be wrong with one of my s9? I have 4 of them, one of them got fried the connections.
did this fix photo?okay what is your voltage rating?
what did you set the hash rate to?
looks like you have a apw3++ or apw3+ psu is that correct?
Assuming you have an apw3+ or apw3++
you can melt out for a few reasons.
High clock like 15th or 16th
voltage drop from 240 to 200 this means more amps and more heat.
connections were not tight due to plugging and unplugging
I have found that a fairly high clock combined with a voltage drop or with a loose connection does exactly what you have.
Try clocking all the rest of your units 1 or 2 th lower than they are right now.
This is s9 14th with APW3++ on 220v using it with latest official firmware, no overclocking. It is operating always on low power mode with average 13,79TH. Together with other machines (total of 4xs9 and 1xS19) connected to one source of 10kw.
It was bought second hand so not sure about sockets usage, anyways ordered new ones from china together with wires for replacement.
The rest of machine have several slighly brown sockets, but this one went all the way.
It shouldnt be the psu also since i already have replaced one, because i thought its the problem.
Thanks!
