I have a fairly modern PC, 12400f, Asus PRIME B660M-A D4 motherboard, 16 gb ddr4 RAM, but an old video card ati hd 6750 1gb ddr5, and the problem is that on the old PC it worked on pci-e 2.0 as it should , on the same computer it only works in pci-e 1.1, I tried moving it to another slot, I tried installing pci-e 2.0 in the BIOS, reinstalling the drivers, but it still works in 1.1 mode, if anyone knows what the problem is, please tell me !
