hello all. so in the bios there is an option for NB config , which seems to be my onboard graphics vram buffer size. i have 8 Gigs of memory and i noticed that the bios vram setting is set to auto. and also has options to "force" and then set the UMA buffer size to auto or anywhere up to 2 Gigs. does anyone know what it does when its set to auto? i mean how much vram will it use? am i better off setting it to 2 Gigs for that buffer size? thanks for any help.
