Now it's very well possible that only one card is recognized as only for that one you installed drivers. Whenever you add any new hardware, even if it's the same as something you have already in the system, you will have to install drivers for it. ID: 40287 ·

Cat 11.7 or Cat 11.8 didn't detect my second GPU either. _\|/_ Urs ID: 40304 ·
