865G Datasheet, PDF (14/249 Pages) Intel Corporation – Intel 865G/865GV Graphics and Memory Controller Hub

Introduction
Introduction
1
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.
The following are the key feature differences between the 82865G GMCH and 82865GV GMCH:
• AGP Interface
— 82865G supports AGP. The AGP interface signals are multiplexed with the Intel^® DVO
interface signals. The 82865GV does not support AGP.
The Intel^® 865G/865GV chipset platform supports the following processors:
• Intel^® Pentium^® 4 processor with 512-KB L2 cache on 0.13 micron process in the 478-pin
package.
• Intel^® Pentium^® 4 processor on 90 nm process.
Note: Unless otherwise specified, the term processor in this document refers to the Pentium 4 processor
with 512-KB L2 cache on 0.13 micron process in the 478-pin package and the Pentium 4 processor
on 90 nm process.
Note: Unless otherwise specified, the term ICH5 in this document refers to both the 82801EB ICH5 and
82801ER ICH5R.
Chapter 1 through Chapter 8 describe the 82865G GMCH. The 82865GV GMCH is described in
Chapter 9 through Chapter 11.
