I think that is why you are having an error after few minutes its because your miner is getting more hotter.
Are you using Afterburner? Try to change the temp limit on afterburner to 65 degrees.
Hotter temp on GPU could leads to temperature protection so this is might be the reason why your miner stop after few minutes.
I'm keeping my GPUs under 55 degrees.
Here is my MSI Afterburner settings:
Power limit: %60
Core: 160
Memory Clock: -300
Thanks.
The power limit which was set in MSI afterburner doesnt really work with MSI 1080 ti Gaming X. I have couple of this gpu (and msi 1070 seahawk), maybe you could try to do several tests like reduce further power limit, but I think the problem may relate to intensity. What's your intensity setting. And dont lower too much your mem clock.
I have set it at %65. Also I have set the core clock at 84, hopefully it work.
The intensity is 16. I tried to lower it to 1 but ccminer ignored it and set to 16.
