Introduction
The Intel^® Intel 4 Series Chipset family is designed for use in desktop platforms. The
chipset contains two components: GMCH (or MCH) for the host bridge and I/O
Controller Hub 10 (ICH10) for the I/O subsystem (G45, G43, P45, P43 Express Chipset
only). The ICH10 is the tenth generation I/O Controller Hub and provides a multitude of
I/O related functions. The Intel G41 Chipset uses the I/O Controller Hub 7 (ICH7).
Figure 1, Figure 2, and Figure 3 show example system block diagrams for the Intel^® 4
Series Chipset.
This document is the datasheet for the following components:
• Intel^® 82Q45 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® Q45 Chipset.
• Intel^® 82Q43 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® Q43 Chipset.
• Intel^® 82B43 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® B43 Chipset.
• Intel^® 82G45 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® G45 Chipset.
• Intel^® 82G43 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® G43 Chipset.
• Intel^® 82G41 Graphics and Memory Controller Hub (GMCH), which is part of the
Intel^® G41 Chipset.
• Intel^® 82P45 Memory Controller Hub (MCH), which is part of the Intel^® P45
Chipset.
• Intel^® 82P43 Memory Controller Hub (MCH), which is part of the Intel^® P43
Chipset.
Topics covered include; signal description, system memory map, PCI register
description, a description of the (G)MCH interfaces and major functional units, electrical
characteristics, ballout definitions, and package characteristics.
Unless otherwise specified, ICH10 refers to the Intel^® 82801JIB ICH10, Intel^®
82801JIR ICH10R, Intel^® 82801JD ICH10D, Intel^® 82801JDO ICH10DO I/O Controller
Hub 10 components.
For the 82G41 GMCH, references to ICH are references to ICH7/ICH7R.
Unless otherwise specified, the information in this document applies to the Intel^®
82Q45, 82Q43, 82B43, 82G45, 83G43, 82G41 Graphics and Memory Controller Hub
(GMCH) and Intel^® 82P45, 82P43 Memory Controller Hub (MCH).
In this document the integrated graphics components are referred to as GMCH. The
Intel^® 82P45 and 82P43 components do not contain integrated graphics and are
referred to as MCH. The term (G)MCH is used when referring to both GMCH and MCH.
Table 1 provides a high-level component feature summary.
