How does shared video memory, a 32 bit O/S and 4 Gig of RAM work?
Does the graphics card reserve it’s RAM at startup and then the 32 bit O/S will see up to 3 gig RAM. Basically, if your graphics card uses 1 gig of RAM (to use easy numbers), will the remaining 3 gig of RAM be used by the O/S effectively utilizing all 4 gig of your memory? Am I making any sense here? To know even one life has breathed easier because you have lived. This is to have succeeded. — Ralph Waldo Emerson –> Reply With Quote –> November 4th, 2008 08:43 AM #2 Remfin View Profile View Forum Posts View Blog Entries View Articles Elder Arcanist Join Date Jun 2003 Posts 9,777 Re: Laptops and Shared Video Memory IIRC this is how it works (please note some of these numbers are wrong and/or gigantic in relation to reality) and the entire 4GB of addressing space is used: First 256MB – reserved for all kinds of legacy reasons/interacting with hardware (you send commands to video cards by sending data to “memory” locations for instance) Next 512MB – video card onboard memory on any mod
