I have MSI RX 460 and it's factory overclock'd. ( Probably only + 10 Mhz ) But i see artifacts sometimes if i don't downclock. The error is - Application has been blocked from accessing graphics hardware- . If i do downclock about %~5 there is no artifact and no driver crashes. Is my Rx 460 faulty? or my motherboard or psu problem? I have 450W Psu which is fine for GPU. Temps are okay max 65 C. I bought few days ago. Can i change it with new one?
