Hi
I've been reading all the issue from page 1, and I also experience some of it. (especially 580 that causing error and it's not as stable as 570)
1. Check your log and find out the GPU that caused error & disable that GPU to find out which one
2. Underclock/Undervolt that GPU or increase the power limit of that GPU
3. Run it for 6 hours or longer
4. Sometimes try different version of Claymore also help
5. Lastly if the problem still occur, setup your claymore to restart every 3, 6, or 12 (-r 360 720 )
6. (Last option) Task scheduler your rig to restart every 12 or 24 hours.
If those helps, you are welcome to donate :
