I for all. I have a problem with 2 Radeon RX 570 crossfire. When it is enabled, all games crashes during loading. If crossfire is disabled, principal adapter work fine and secondary adapter work fine.
My configuration is:
Mainboard: Asrock Extreme 3
Processor: AMD Phenom II x4 955
Graphics: 2x Sapphire Radeon RX 570 Nitro+
Ram: 16 GB
Power supply: 750W with 2 PCIe 8 pin (6 + 2) cable
Some suggestion, please? Thanks!
