1.6.1.2 Dynamic Video Memory Technology (DVMT 5.0)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization. DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance. The amount of system memory
allocated to DVMT varies depending on the amount of total system memory installed
as well as the operating system being used. For Microsoft Windows Vista*, a
minimum of 128 MB can be allocated to DVMT and a maximum of over 2 GB can be
allocated to DVMT with the correct amount of memory installed. DVMT returns system
memory back to the operating system when the additional system memory is no
longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications. An example of this
would be when using VGA graphics under DOS. Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.
NOTE
The use of DVMT requires operating system driver support.
1.6.1.3 Configuration Modes
The video modes supported by this board are based on the Extended Display
Identification Data (EDID) modes of the monitor to which the system is connected.
Standard monitors are assumed.
1.6.1.4 Analog Display (VGA)
The VGA port supports analog displays. The maximum supported resolution is 2048 x
1536 (QXGA) at a 75 Hz refresh rate.
The VGA port is enabled for POST whenever a monitor is attached, regardless of the
DVI-D connector status.
1.6.1.5 Digital Visual Interface (DVI-D)
The DVI-D port supports digital DVI displays. The maximum supported resolution is
2048 x 1536 (QXGA) at a 75 Hz refresh rate. The DVI port is compliant with the
DVI 1.0 specification.
