Check your bios settings that the PCI-e slot is set to 16x or auto.
That's about all you can do, although on a radeon 250 I doubt 8x is going to matter anyway as it;s probably not even using all the bandwidth.

What motherboard do you have and which PCIe x16 slot are you using, if there are more than one? Also, do you have any other PCIe devices or M.2 or NVME or anything like that? Some things can take away from the graphics card's lanes.

Same issue here, I got an msi r9 270x with crimson recently updated with ddu to relive 16.12.2 and crimson shows pci express 2.0 x8 instead of x16. My mobo is gigabyte ex58ud3r rev1.0 and no other devices used with pci... Tried everything till now, clean the dust, use the second pci express of the mobo which worked at x16 for some days then I noticed it changed to x8 again, reinstall drivers and windows again, tried both win7 and win10, I haven't resolved it.... Bios also checked, all defaults apart from the xmp profile that I activated and sata mode that I changed from ide to ahci....

Thanks for the advice! The only devices are dvd rw and one ssd in sata, if I change the slots it may fix the issue? Is it necessary to format again for this change?
