The Intel® 82865G and the Intel®82865GV chipsets are designed for use in desktop systems based
on an Intel® Pentium® 4 processor with 512-KB L2 cache on 0.13 micron process in the 478-pin
package or the Intel® Pentium® 4 processor on 90 nm process, and supports FSB frequencies of
400 MHz, 533 MHz, and 800 MHz. The 82865G GMCH is part of the Intel® 865G chipset, the
82865GV GMCH is part of the Intel® 865GV chipset. Each chipset contains two main
components: Graphics and Memory Controller Hub (GMCH) for the host bridge and I/O
Controller Hub for the I/O subsystem. The GMCH provides the processor interface, system
memory interface, hub interface, CSA interface and other additional interfaces in an 865G/ 865GV
chipset desktop platform. Each GMCH contains an integrated graphics controller (IGD). The 865G
/865GV chipset use either the 82801EB ICH5 or 82801ER ICH5R for the I/O Controller Hub. This
document is the datasheet for the 82865G and the 82865GV Graphics and Memory Controller Hub
(GMCH) component.
