My Sapphire 280x toxic cards continue to hang almost every hour or two. I tried every possible settings for power, clocks, intensity, VM set to 24 GB and nothing works. Most of the cases -wd 1 or -r 0 options manage to restart the miner but sometimes the zecminer window is frozen, I can't even manually or with killing with the task manager close it. Is there a script that can recognize when a zecminer window is not responding and then restarting the windows? I know that -r 1 can restart but I don't want to do it so often. It will waste too much time since in 4 out of 5 cases -r 0 does the job.
