PCIEx16_2 not found

[Fonqas]

Hello i just bought a new asus z270-k motherboard and i3-6100, the problem is that PCIEx16_2 isnt available in bios

Looking at the manual under 2.6.3 System Agent (SA) Configuration there is only PCIEx16_1 Link Speed is listed so theres probably no option for PCIEx16_2?

That doesn't mean it isn't "available" though. I'd assume whatever device is using it, would automatically use whatever is possible from it (x4/x2/x1).

What do you mean?

If the GPU not seen in Windows at all?

 

Also, you say "new" but that's CPU and mobo are fairly old. New new, or new to you? In other words, are you certain it's not defective?

No worries, the lack of seeing the other ones may be due to the limited PCIe lanes in the CPU. I am not certain, because I don't mine, but that may be something to look into.
