I've got this moterboard AM785GMT-UD2H and a problem - my graficcard did not work at 16 lines but in 8. I've make the onboard grafik sollution HD 4200 "disconect" at the BIOS - only the 5770 works. It is korrect in the 2.0 16 slot - but only working with 8 lines...? Driver is 10.7. What is wrong?
The Bios is F8 newest version.
