It seems the Dag file hit 3 GB, i keep getting out of memory on my 1060 3 GB mining ETH/ETC.
I guess this Month is it instead of next month ....

I have in rig there is one old GPU hd7900 series 3GB. It works without problems. I don't turn it off because I have access to cheap electricity. I know that you have a different problem. I think the problem is driver compatibility. Need more description of the problem to find a solution.
