I apologize for my bad English, I'm using Google translator
I am experiencing an issue with my RX 5700 XT Pulse Sapphire. After 30-40 minutes playing the PC screen goes black and a reboot occurs. I've already updated the bios, I've updated the video card and chipset drivers, I've already changed the bios settings to PCI Express 3, I've also changed the power settings for maximum performance, anyway ... From the reports here on the site the situation it's disheartening! The same complaint is old and it seems that it has been going on for months without solution, my configuration is:
Motherboard: Gigabyte X570 Gaming X (BIOS UPDATED)
CPU: Ryzen 7 2700X
32GB HyperX DDR4 2800MHz memory
Seasonic Silent 620W S12II 80 Plus Bronze Power Supply
I honestly don't know what else to do.
