System Overview 2.4.9 Graphics Subsystem These systems use the 82945G GMCH component that integrates an Intel 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 Recommended for: 82945G GMCH Integrated Graphics Controller Hi 2D, Entry 3D Bus Type Int. PCI Express Memory Amount Memory Type 8 MB pre-allocated DVMT 3.0 DAC Speed 400 MHz Maximum 2D Res. Software Compatibility Outputs 2048x1536 @ 85 Hz Quick Draw, DirectX 9.0, Direct Draw, Direct Show, Open GL 1.4, MPEG 1-2, Indeo 1 RGB The graphics subsystem of all form factors supports upgrading through the PCI Express x16 graphics slot or through the PCI 2.3 slot. ✎ The PCI Express x16 slot of the USDT form factor only supports a reverse-layout SDVO ADD2 card. A full graphics controller upgrade on the USDT form factor is only possible through the PCI 2.3 slot 2.4.10 Audio Subsystem These systems use the integrated HDaudio controller of the chipset and the Realtek ALC260 High Definition audio codec. High definition 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 microphone in and headphone out audio jacks as standard. 2-24 www.hp.com Technical Reference Guide
