Hello,

I have the same error, but I cannot figure out why.

I had 2 Sapphire RX580 8Gb cards running since September.

They ran without any problems (Claymore settings 1260/2230/910)

PSU : EVGA 1600 T2

Since I added a 3rd card I have approx every 3-4 hours the message :
 
WATCHDOG: GPU 1 hangs in OpenCL call

Sometimes it's GPU 3, sometimes GPU 2...

I put specific values for GPU 3 (115/2170/910) and always the same problem.

I changed the Rizer, reinstalled the drivers but nothing seems to work. Maybe a Win10 issue ?

Thx
