How to Configure Shared Memory through BIOS

How to Configure Shared Memory through BIOS

Your computer uses video memory to generate and display 3D graphics on your computer monitor. Video memory is a form of RAM (Random Access Memory) that uses binary data required for 3D playback. This graphics capability either comes built into your motherboard; or it is provided by a graphics card (also called a video card).

Depending on its 3D graphics capability, your computer may have to draw on its own RAM to meet its video memory needs. This creates the need for shared memory, in which case, your computer's RAM will be shared between its CPU (Central Processing Unit) and its graphics chip.


1). Start up your computer and enter your BIOS setup. You will do this by tapping the appropriate key or keys during the boot up process. (Review the start-up messages on your screen for the particular key/s your system requires you to use).

2). Once you access your BIOS set up, select the Integrated Peripherals menu.

3). In the Integrated Peripherals menu, select the option for AGP aperture size.

4). Under this option, you will now allocate a specific amount of RAM for shared video memory. Generally, you may chose to allocate an amount ranging from 8MB to 64MB RAM or this purpose. In act, on newer PC's, you may actually allocate up to 128MB of RAM for video memory.

5). With a desired amount of video memory specified, you will then save your changes. Exit your BIOS set up. Your PC now has a shared memory, with a portion of its RAM allocated for video memory, and the rest used by the CPU.


Computer memory refers to the physical devices used to store data or programs on a temporary or permanent basis for use in an electronic digital computer.
