System Overview 2.4.9 Graphics Subsystem These systems use the 82915G or 82915GV 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 2-5 lists the key features of the integrated graphics subsystem. Table 2-5 Integrated Graphics Subsystem Statistics 82915G or GV 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 of the 82915G used in the SFF, ST, MT, and CMT form factors supports upgrading through a PCI Express x16 graphics slot. The IGC of the 82915GV used in the USDT form factor does not support a PCI Express x16 graphic slot and may only be upgraded through the PCI 2.3 slot. 2.4.10 Audio Subsystem These systems use the integrated AC97 audio controller of the chipset and the ADI 1981B audio codec. These systems include microphone and line inputs and headphone and line outputs and include a 3-watt output amplifier driving an internal speaker. All models feature front panel-accessible microphone in and headphone out audio jacks as standard. 2-28 361834-002 Technical Reference Guide
