Dynamic Video Memory Technology
DVMT mode is memory that is dynamically allocated based
on memory requests made by application and are released
back to the system once the requesting application has
been terminated.
Fixed mode is non-contiguous page locked memory
allocated during driver initialization to provide a static
amount of memory.
Both allows the combination of both Fixed and DVMT type
driver allocation methods, used to guarantee a minimum
amount of memory but give the flexibility of DVMT
allocation scheme and performance enhancement. These
mode options will ensure that a certain minimum amount of
memory will always be dedicated to graphics.

Media Accelerator 900 White Paper at
