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 256 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 system memory is installed.
DVMT returns system memory back to the operating system when the additional
system memory is no longer required by the graphics subsystem.
