Intel Desktop Board D915GUX/D915GHA Technical Product Specification • Video Asynchronous dual monitor display with ADD2 card Hardware motion compensation for software MPEG2 decode Two multiplexed DVO port interfaces with 200 MHz pixel clocks using an ADD2 card • Dynamic Video Memory Technology (DVMT) support up to 224 MB • Intel® Zoom Utility For information about DVMT Obtaining graphics software and utilities Refer to Section 1.6.1.2, page 24 Section 1.3, page 17 1.6.1.2 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 224 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. 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 Advanced Digital Display 2 (ADD2) Card Support The GMCH routes two multiplexed DVO ports that are each capable of driving up to a 200 MHz pixel clock to the PCI Express x16 connector. The DVO ports can be paired for a dual channel configuration to support up to a 400 MHz pixel clock. When an ADD2 card is detected, the Intel GMA900 graphics controller is enabled and the PCI Express x16 connector is configured for DVO mode. DVO mode enables the DVO ports to be accessed by the ADD2 card. An ADD2 card can either be configured to support simultaneous display with the primary VGA display or can be configured to support dual independent display as an extended desktop configuration with different color depths and resolutions. ADD2 cards can be designed to support the following configurations: • TV-Out (composite video) • Transition Minimized Differential Signaling (TMDS) for DVI 1.0 • Low Voltage Differential Signaling (LVDS) • Single device operating in dual channel mode • VGA output • HDTV output 24

1.6.1.2

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 224 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.

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

Advanced Digital Display 2 (ADD2) Card Support

The GMCH routes two multiplexed DVO ports that are each capable of driving up to a 200 MHz

pixel clock to the PCI Express x16 connector.

The DVO ports can be paired for a dual channel

configuration to support up to a 400 MHz pixel clock.

When an ADD2 card is detected, the Intel

GMA900 graphics controller is enabled and the PCI Express x16 connector is configured for DVO

mode.

DVO mode enables the DVO ports to be accessed by the ADD2 card.

An ADD2 card can

either be configured to support simultaneous display with the primary VGA display or can be

configured to support dual independent display as an extended desktop configuration with different

color depths and resolutions.

ADD2 cards can be designed to support the following

configurations:

•

TV-Out (composite video)

•

Transition Minimized Differential Signaling (TMDS) for DVI 1.0

•

Low Voltage Differential Signaling (LVDS)

•

Single device operating in dual channel mode

•

VGA output

•

HDTV output
