G965 Express Chipset
The Intel G965 Express chipset consists of the following devices:
•
Intel 82G965 Graphics and Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
•
Intel 82801HB I/O Controller Hub (ICH8) 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 ICH8 is a centralized controller for the
board’s I/O paths.

Intel G965 Graphics Subsystem
The Intel G965 Express chipset contains two separate, mutually exclusive graphics
options. Either the GMA X3000 graphics controller (contained within the 82G965
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 X3000 graphics controller is disabled.
