Chipset Overview

The Intel 3000 chipset, designed for use with the Quad Core/Dual Core Processor
in the 65mm/90nm Process in the LGA 775 Land Grid Array Package, is comprised
of two primary components: the Memory Controller Hub (MCH) and the I/O Control-
ler Hub (ICH7R). In addition, Intel's PCI-X (PXH-V) is used for added functionality.
The PDSMi+ provides the performance and feature-set required for the high-end
UP Server market.
Memory Controller Hub (MCH)
The function of the MCH is to manage the data fl ow between four interfaces: CPU
interface, DDR2 System Memory Interface, PCI Express Interface, and Direct Media
Interface (DMI). The MCH is optimized for the 65mm/90nm LGA775 processors. It
supports one or two channels of DDR2 SDRAM.
The I/O Controller (ICH7R) provides the data buffering and interface arbitration
required for the system to operate effi ciently. It also provides the bandwidth needed
for the system to maintain its peak performance. The Direct Media Interface (DMI)
provides the connection between the MCH and the ICH7R. The ICH7R supports
up to six PCI-Express slots, four Serial ATA ports, six USB 2.0 ports and two IDE
devices. In addition, the ICH7R offers the Intel Matrix Storage Technology which
provides various RAID options for data protection and rapid data access. It also
supports the next generation of client management through the use of PROActive
technology in conjunction with Intel's next generation Gigabit Ethernet controller.
Intel ICH7R System Features
The I/O Controller Hub provides the I/O subsystem with access to the rest of the
system. Functions and capabilities include:
*Advanced Confi guration and Power Interface, Version 2.0 (ACPI)
*Intel I/O External Design Specifi cation (EDS)
*Intel's 3000 Memory Controller Hub (MCH) External Design Specifi cation (EDS)
*Intel I/O Controller Hub 7 (ICH7R) Thermal Design Guideline
*Intel 82573 Platform LAN Connect (PLC) PCI Design
*Low Pin Count (LPC) Interface
