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.
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.
