Graphics memory is generally classified into two major types: dedicated and shared.
Dedicated graphics memory is memory that is exclusively used by the graphics system. Non-graphics applications cannot access this type of memory. This is commonly referred to as “on-board” or “local video memory” (i.e. close to the graphics processing unit - GPU). However, it isn’t limited to on-board memory and a portion of system memory can also be dedicated to the graphics subsystem. It is exclusively owned by the graphics subsystem.
Shared system memory can be used by the graphics subsystem when needed. It is often referred to as “non-local video memory” (i.e. far from the GPU). The shared memory is available to other subsystems or non-graphics applications when it is not being used by the graphics subsystem. Thus, it is never guaranteed to be available for graphics because it could already be in use.
Typical error message that you can have: 128 Mb non local video memory or more.
You can modify the memory usage of your graphics board in order to get a maximum performance. GPU requires 128 MB for minimal performance (256 Mb optimal).
- Backup your current BIOS Settings.
- Now in the BIOS, modify the value for "non local video memory" (resp. "shared memory") to 256 MB or higher. Attention: depending on your BIOS, these values naming can be different (possible names of the value: - AGP aperture).
WARNING: improper modification to BIOS can damage your computer. We can not assume liability or responsibility for bad settings.
