1-2 Chipset Overview
Intel’s Lakeport (945G/P) chipset consists of two primary components: the Graphics
Memory Controller Hub (GMCH)/Memory Controller Hub (MCH) and the I/O Control-
ler Hub (ICH7). Optimized for the Celeron, Pentium 4, Pentium D processors in an
LGA775 Package, the Lakeport (945G/P) provides the performance and feature-set
required for high-end UP dual core processor desktop solutions.
Graphics Memory Controller Hub (GMCH)/Memory Controller
Hub (GMCH)
The GMCH/MCH supports high-performance integrated graphics and manage the
data fl ow of the following fi ve interfaces: the CPU interface, DDR2 interface, PCI
Express Graphic Interface, the DMI (Direct Media Interface) and integrated graphics
with display interfaces (*GMCH only) . The GMCH/MCH supports a FSB frequency
of 533/800/1066 MHz using a scalable CPU. It supports up to two channels of
non-ECC DDR2 400/533/667 SDRAM. The integrated Graphics Controller provides
3D, 2D and display capabilities. The GMCH/MCH also supports advanced desktop
power management.
