I just acquired Sapphire Radeon RX Vega 64 and I can't get the card to run properly, I try to play gta5, doom, and many others games and all will last less that five minute and the game will crash (black screen, freezing). I'm new to AMD GPU and Radeon Software, i'm not sure what the problem is or what setting I need to use for my setup.
The GPU is connected to the PSU with two separate 8pin cable and my specs are.
