Not getting an image with two graphics cards

[johanisgaming]

Hey guys i have had the red devil rx480 for about 6 months and i've never had any problems with it and i decided that i wanted to build a miner so i bought an rx 470 and i crossfired. They both ran fine but I went to flash both of them and the rx 470 was fine after the flash but the rx 480 won't work when i connect the pci e to it the screen will stay black and say there is no image i can use the computer only when the rx 470 alone is connected. i have the backups for the bios but the computer does not recognize the rx 480 please help.

Unplug>Open graphics card>Connect 1+8 pins on board[under backplate]>connect to pci port>turn on the pc>unplug>disconnect the pins>Reassemble card>Reflash.

So you used seperate BIOS for each card?
