My 570 8gb nitro got this kind of error..
OpenCL error -4 - cannot write buffer for DAG
even I change my Vram to 17500-25500
Is anyone of you have the solution for this? I already change also the riser, cable etc but I always got this message continuously..
I fixed an issue like that with a combo of more VRAM (64 GB from 32) and more RAM (8 GB from 4).
I am not sure though which one was the key, or if both were necessary .... point is that it works (for me).
