Just RMA it was not meant to be, personally i would take refund and go for a custom, AMD did an oopsie and we all make oopsies sometimes, but AMD can handle this much better eitherway they should not rely on customers to figure this out let alone YouTubers to communicate about these issues.
honestly 7900 series launch is doa and i do not mean dead on arival but damaged on arival by faulty vapor chambers or cards, AMD just needs to do right thing soon before its to late, and go the EVGA route not the gigabyte route.
