System Overview
2.4.9 Graphics Subsystem
These systems use the Q965 GMCH component that integrates an integrated graphics controller
that can drive an external VGA monitor. The integrated graphics controller (IGC) features a
333-MHz core processor and a 400-MHz RAMDAC. The controller implements Dynamic Video
Memory Technology (DVMT 3.0) for video memory. Table 2-6 lists the key features of the
integrated graphics subsystem.
The IGC supports dual independent display for expanding the desktop viewing area across two
monitors. The graphics subsystem of all form factors supports upgrading through the PCI
Express x16 graphics slot.
✎
The PCI Express x16 slot of the USDT form factor supports either a reverse-layout SDVO ADD2
card or a low-profile PCIe x16 graphics card.
2.4.10 Audio Subsystem
These systems use the integrated High Definitions audio controller of the chipset and the Realtek
ALC262 High Definition audio codec. HD audio provides improvements over AC’97 audio such
as higher sampling rates, refined signal interfaces, and higher signal-to-noise ratio audio
processors. These systems include a 1.5-watt output amplifier driving an internal speaker. All
models feature front panel-accessible stereo microphone in and headphone out audio jacks as
standard.
