Ouch. What freq did you overclock it to and for how long? Auto fan?
656Mhz, I moved it to a new place because it is too noisy to put at home, it has been running for less than 12 hours since move. Fixed fan rate until this noon, I see the temperature increased to 79 then I switched to auto fan.
That is a shame... is it a board hash down or control board?.. if board.. it could just be seeking freq...or power can cause them to loose a board... keep doing cold reboots (thats pull the power out the PSU and restart it.. I have alot of S9's and i learnt the hard way.. self taught...
Ps are all 3 boards down? or just 1?
