I managed them both to get to work now, it was the power cable problem i used for second GPU. Bought new one and it works now. But now i got another problem, my MoBO stupidly using second GPU as a MAIN PCI E ( its in pci express x1 slot AND below the first gpu ). So i cant realy use the PC for gaming now or anything else. Can i change that or no? i guess there could be an option in BIOS or nvidia control center to make this happen? or should i try to use my second gpu in other PCI e x1 slots? ty for all the help
I would look in the bios to see if you can manually set your primary adapter to the GPU in the physical x16 slot. It is a little unusual for it to default to that x1 slot, but it is an old motherboard.
