Good afternoon, do you have an older BIOS, like version 3002? The one you posted worked correctly, but I believe that due to some incompatibility, it is limiting my old GTX 1050 ti to PCI-E 1x. I tested it with the older BIOS, version 0402, and it worked smoothly at x8 (I'm using a 3 2200g, hence the 8x limitation). Sorry for the bad English, I'm using Google Translate, lol.
