Graphics Features
Intel Q35 Graphics Subsystem
The Intel Q35 chipset GMCH provides an integrated graphics device (IGD) delivering cost
competitive 3D, 2D and video capabilities. The GMCH contains and extensive set of instructions for
3D operations, 2D operations, motion compensation, overlay, and display control. The GMCH’s
video engines support video conferencing and other video applications. The GMCH uses a UMA
configuration with up to 256 MB of DVMT for graphic memory.
400MHz Integrated 24-bit RAMDAC
Up to 2048x1536 @ 75Hz refresh
Hardware Color Cursor Support
Analog Display Support
DDC2B Compliant Interface
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.
