It is not the issue as .19.5 works at DAG creation but after some hours it also crashes... I’m switching to phonies minter for now to see if I continue to get stability issues also I do care as an RMA can take months.
What I do is send to RMA (I only had to do it twice ever, so I'm lucky), buy a new card and sell the one that comes back from RMA. But you need to have spare cash for that.
