Many graphic-intensive applications require a minimum amount of video memory in order to operate correctly. How much video memory does an Intel® 865G chipset-based system with "integrated graphics" have? The amount of video memory allocated depends upon the amount of pre-allocated memory set for your system plus something called Dynamic Video Memory Technology (DVMT), or the amount requested by the operating system.
- Dynamic Video Memory Technology
DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance.
- Operating System
When the memory is no longer required, it is returned to the operating system for use by other applications or system functions. DVMT allocates memory based on system needs and is not user-configurable. Memory can be allocated up to the maximum limit set by the graphics driver (see Figures 1& 2). The maximum limit of video memory allocated by DVMT is dependent upon the total amount of system memory installed (see Table 1).
