Such a question about AMD video cards is of interest, whether the issue with mining drivers for 8 gigabyte cards will be resolved, because with an increase in the dag file they will stop mining! Because out of 8 gigabytes the card uses only 3.9 gigabytes of video memory!
It turned out that there is a limitation on the size of AMD video cards available DAG more than 4 gigabytes when mining on the Ethash algorithm. The problem is typical for all video cards larger than 4 gigabytes from AMD. Thanks in advance!
