Graphics Features
Intel 945G Graphics Subsystem
The Intel 945G chipset contains two separate, mutually exclusive graphics options. Either the GMA950 graphics
controller (contained within the 82945G GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI
Express x16 add-in card is installed, the GMA950 graphics controller is disabled.

Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through Direct AGP, and highly efficient memory
utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics
performance. Up to 224 MB of system memory can be allocated to DVMT on systems that have 512 MB or more of
total system memory installed. Up to 128 MB can be allocated to DVMT on systems that have 256 MB but less than
512 MB of total installed system memory. Up to 64 MB can be allocated to DVMT when less than 256 MB of
