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. Table 2-6 Integrated Graphics Subsystem Statistics Q965 GMCH Integrated Graphics Controller Recommended for: Hi 2D, Entry 3D Bus Type Int. PCI Express Memory Amount 8 MB pre-allocated Memory Type DVMT 3.0 DAC Speed 400 MHz Maximum 2D Res. 2048x1536 @ 85 Hz Software Compatibility Quick Draw, DirectX 9.0, Direct Draw, Direct Show, Open GL 1.4, MPEG 1-2, Indeo Outputs 1 RGB 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.
