If you install the cards separately, try inserting both and then connect the CrossFire bridge. Even if the driver successfully detects the graphics card, it'll sometimes misbehave if you then try to insert the card into a different PCIe slot. If this still does not work, you can try installing the first card in your primary PCIe slot, remove it, install the second card in the secondary PCIe slot, and then finally insert the first card in slot one again.ĪMD's drivers can be fussy. If you still can't proceed, remove the CrossFire bridge until the second card is detected correctly in the device manager and all drivers are installed. If you run into these issues, you can typically solve them by first installing the main graphics card, and then inserting the second card.
