-eres 0 fixed this problem for me while mining ETC. I have not tried it yet with ETH. I will prob. be moving to ETH soon as I have been toggling back and forth. No idea why it is not working for some. I have 12x 3gb Gigabyte OC cards (the cheapest 2 fan versions) on this rig
worked for me after my evga 1060 3go got me this error after 1 years of good work.
Dont know what -eres 0 does but its work!
I hope it will work until june 2019
It won't. Give it around 7-10 days and it will break again.
Prepare to install something else or mine another coin.
