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

Try a clean uninstall of drivers using DDU

http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

then install blockchain drivers for windows 10

If this doesn't work, I suggest updating to Win10 Fall Creator's Update and to AMD's 17.10.3.

It could very well be a windows update sneaked on you and wrecked your GPU drivers.

I'm running on RX580 Sapphire Nitro+. Was running on Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23 getting 30mhs. Kept getting the OpenCL GPU Hang errors. I did the AMD 17.10.3 update and tried to run again but my hashrate greatly reduced to 23mhs. Any idea how to run on the new driver and get 30mhs?
