Hi guys. System fx6300 motherboard gigabyte 970 d3s3p psu 750watt +80. I have 2 sapphire rx 480 8gb graphics cards. One is model 11260-01-20g and the other model is 11260-07-20g. I do not get an error even when I overclock a high amount of 01-20g model. Even when I overclock the other on my other card, I get an error. Sometimes I get an error when I do not overclock. I've tried every possible way. I changed the bios, changed the board, changed the psu, gave the voltage but my problem did not improve. I'm glad you helped me.
What for error do you get?
Did you try to reinstall the drivers?
