HP 8200 tower manual Supported Intel Processor IGC Specifications

Integrated Graphics Subsystem

Each system implements one of two IGC types; the Intel HD Graphics 2000 or the Intel HD Graphics 3000, depending in the processor installed. Table 6-1 lists the type of IGC associated with the types of processor supported by these systems.

The IGC uses a portion of system memory for instructions, textures, and frame (display) buffering. At boot time, 32 megabytes of system memory is pre-allocated for the graphics controller whether using Windows XP, Windows Vista, or Windows 7. Using a process called Dynamic Video Memory Technology (DVMT), the IGC dynamically allocates display and texture memory amounts according to the needs of the application running on the system.
