You can disable the loop in the Settings => ASICS Control Panel

It means the loop 9 is having some issue.

You can disable one ASIC at the time to find out which one(s) is/are having issues.

[wh00per]

The issue is that loop 9 is the hottest ASIC spot.

You can blow it a little with a shop-vac or something.
I was having the same problem with mine when it was full of dust.

If the cleaning does not help, lower the voltages a little for that board, so that it does not run that high.

[hectordsd]

disabling the entire loop 9 solved the miner from dying, now its stable but  hashing 3770, thanks for your reponses,

[hectordsd]

now it seems to work correctly now i have disabled also the chip 21
