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. ► DVMT/FIXED Memory Select graphics memory size for Fixed or DVMT usage. ► CPU Configuration Press to go to its submenu. 23
