1-2 Chipset Overview
The Intel Q965-Express/G965/P965 Chipsets are specially designed for use with
Quad-core or Dual-core 1066/800/533 MHz processors. These chipsets consist of
two primary components: the Graphic Memory Controller Hub (GMCH)/Memory
Controller Hub (MCH) and the I/O Controller Hub (ICH8). Optimized for the Quad-
core/Dual-core Core2 Duo/E6000/E4000/Xeon 3000/Pentium
®
D/Pentium

4/Cel-
eron Processor via an LGA775 socket, the Q965-Express/G965/P965 provides the
performance and feature-set required for high-end UP quad-core and Dual-core pro-
cessor desktop solutions. (Note: GMCH is for the Q965-Express and G965 only.)
Graphic Memory Controller Hub (GMCH)/Memory
Controller Hub (MCH)
The GMCH/MCH manages the data fl ow of the following interfaces: the CPU inter-
face (FSB), the System Memory interface (DRAM Controller) and the I/O Control-
ler through DMI (Direct Media) Interface. The MCH supports a FSB frequency of
1066/800/533 MHz using a scalable CPU. The Q965-Express/G965/P965 platforms
support the eighth generation I/O Controller Hub (Intel ICH8) to provide a variety
of I/O related functions.
Intel ICH8 System Features
The Intel ICH8 offers the data buffering and interface arbitration required for the
system to obtain peak performance. The Intel ICH8 supports up to six PCI-Express
root ports, up to four SATA ports at generation 1 and 2 speeds and up to ten USB
2.0 ports. In addition, the Intel ICH8 features High Defi nition Audio controller which
supports extreme multimedia applications and various third party codecs.
