Problem with HD 4650, HD 4770 & HD 5770

Hello guys, I've a problem with HD 4650 & HD 4770 on my motherboard GA-G31M-ES2L V2 (latest bios), HD 4650 only runs PCIE x1 1.1, my HD 4770 & 5770 only runs PCIE x2 1.1.

But other cards runs at full speed PCIE x16 1.1 (HD 2600 Pro, GT 240, 9800 GT, GTS 450, GTX 1050), I tried numerous processor swap but the results always stay the same

I also tried it on my B450 mobo and they run at the desired full speed PCIE x16 1.1, what seems to be the problem with the GA-G31M-ES2L V2 motherboard here? Thanks in advance
