Asus motherboard won't start gpus from PCI Express x1

[JaniBaram]

My asus motherboard cannot start gpu that I connect to the PCI Express x1
However I tried each card on the 16x and they work fine.
I got the assus h270 plus. I would be glad if someone could help me work this out....
The motherboard has only two pairs of 16x and the rest four are 1x...

Have you changed the pcie speed to gen1 or gen2 in the bios/uefi?

I'm on the PEG port Configuration in the BIOS Mode right now
There is only PCIEX16_1Link Speed option and it is set to Gen2.
Does that means I can only edit the 16x port pcie?
I don't see anything else.

In the PCI Express Configuration
Also the PCIE speed is set to Gen2.
What about those Sata / ahci settings, do they matter?
