I used AMIBCP v4.53 to modify netbook bios and changed all 'Access/Use' values to 'User'. After flashing it I see much more options in bios. When I change 'UMA Frame buffer Size' in the unlocked bios to higher it doesn't seem to change anything. Same if I change the value by editing bios and flashing it. It just doesn't seem to affect anything. I would like to set constant video memory used by the APU at 512MB. So when I boot up Windows it will show 8GB RAM (~7,49 available). Also tools like GPU-Z should show 512MB memory size. Does anyone know how to do this?
not sure but i think it uses part of its own mem. and part of the system ram.. split ram share ? look into schematics i think. or others examples of similar UMA board manufacturer bios hacks.
