Dynamic Video Memory Technology (DVMT) dynamically allocates system memory for use
as video memory to ensure the most efficient use of available resources for maximum 2D/3D
graphics performance.
The amount of video memory allocated depends upon the amount requested by the 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. This
BIOS option allows you to adjust the amount of memory available for DVMT.
Fixed is a memory allocation method addition to the Unified Memory Architecture (UMA) concept,
wherein a static amount of page-locked graphics memory is allocated during driver initialization.
This fixed amount of memory will provide the user with a guaranteed graphics memory at all
times, and will no longer be available to the OS.
DVMT is an enhancement of the UMA concept, where in the graphics driver allocates memory
as needed for running graphics applications. If a user is not performing any graphics-intensive
operations, most of the DVMT memory can be utilized by the OS for other uses. We recommend
using DVMT setting for better overall system performance.
