Hello everyone.... First time posting 
I had a nice but very old ivy bridge set up with an i5 3570k, Asus P8z68-v Pro Gen3 motherboard and an Asus Directcu II GTX 580 Graphics card. Everything was working fine and still is however, I was given another GTX 580 graphics card by a family member. This one was an EVGA super clocked GTX 580. Seeing as my motherboard is supposed to support SLI and I have a decent PSU (corsair RM 850) I thought I may as well put it into my system and run them both in SLI even though they may require high power draw and there is obviously a more efficient solution out there.
However when loaded into windows 10 with the latest Nvidia drivers the Nvidia control panel did not give an option for SLI and device manager does not recognise the second EVGA card. Both cards work perfectly on their own when placed in the first PCIeX16 slot. However, when placed in the second white pciex16 slot there is no display from either card.
Does this mean that my motherboard is defective or am I missing something simple? I have had this board since very close to its release years ago... could it require a bios update? I am beginning to think that my board has been defective since it was bought but I have never noticed since I only ever ran one GPU and never tested the second slot
Also tested the 3rd x16 slot which runs and 4x however card is detected fine and I even get an output though SLI obviously cannot be enabled.
Thanks in advance for any help)
