Cezarr, I have this problem with ALL the 570 / 580 .
You need to lower intensity from the 228/256 suggested by the software, GGS can't keep up with the card, I don't know why
By doing that mining speed is lower by a 20 % but it works
It is more accurate to say that the cards cannot keep up with GGS's NeoScrypt kernel.
I would increase the power limit and undervolt the core.
There should be no need to lower the intensity.
