	This motherboard doesn't have that option i'm affraid. Be curious, why do you want to change that? Cheers.

	I think it depends on the video card's bus specs. If it's PCIE 2.0, the PCIe bus degrades to 2.0 speeds automatically.

	Try to find: "BIOS and Kernel Developer?�s Guide (BKDG) for AMD Family 16h Models 30h-3Fh Processors" pdf doc. In doc you can find register address and values that you need. Next use some tool to read/write registers. ~51% chances to success, IMHO. For example this string on linux to read ryzen CPU temp: echo $((0x`setpci -s 00:0.0 60.l=0x59800 && setpci -s 00:0.0 64.l`/2097152*5/4)) (write then read)
