1-2 Chipset Overview
Built upon the functionality and the capability of the 7520 chipset, The X6DH3-
G2/X6DHi-G2 motherboard provides the performance and feature set required for
dual processor-based servers, with confi guration options optimized for communica-
tions, presentation, storage, computation or database applications. The Intel E7520
chipset consists of the following components: the E7520 Memory Controller Hub
(MCH), the 6300ESB I/O Controller Hub (6300ESB ICH), and the Intel PCI-X Hub
(PXH).
The E7520 MCH supports single or dual Xeon EM64T processors with Front Side
Bus speeds of 800 MHz. Its memory controller provides direct connection to two
channels of registered DDR2 with a marched system bus address and data band-
widths of up to 5.4GB/s. The E7520 also supports the new PCI Express high speed
serial I/O interface for superior I/O bandwidth. The MCH provides three confi gurable
x8 PCI Express interfaces. These interfaces support connection of the MCH to a
variety of other bridges that are compliant with the PCI Express Interface Specifi -
cation, Rev. 1.0a.
6300ESB System Features
The I/O Controller Hub provides the I/O subsystem with access to the rest of the
system. It supports 2-channel Ultra ATA/100 Bus Master IDE Controller, two Serial
ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/Flash BIOS Interface, PCI
2.3 Interface, and Integrated System Management Controller.
6300ESB ICH System Features
The 6300ESB ICH system consists of:
The I/O Controller Hub provides the I/O subsystem with access to the rest of the
system. Additionally, it integrates many I/O functions.
The 6300ESB integrates: 2-channel Ultra ATA/100 Bus Master IDE Controller,
two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/Flash BIOS
Interface, PCI-X (66MHz) 1.0 Interface, PCI 2.2 Interface and System Manage-
ment Controller.
