The Intel Q965 Express chipset consists of the following devices:
•
Intel 82Q965 Graphics and Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
•
Intel 82801HO I/O Controller Hub (ICH8DO) with DMI interconnect
The GMCH component provides interfaces to the CPU, memory, PCI Express, and the
DMI interconnect. The component also provides integrated graphics capabilities
supporting 3D, 2D and display capabilities. The ICH8DO is a centralized controller for
the board's I/O paths.

Intel Q965 Graphics Subsystem
The Intel Q965 Express chipset contains two separate, mutually exclusive graphics
options. Either the GMA 3000 graphics controller (contained within the 82Q965
GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI Express
x16 add-in card is installed, the GMA 3000 graphics controller is disabled.
