Chipset Overview
Built upon the functionality and the capability of the E7520 Lindenhurst
chipset, The X6DH8-G/X6DHE-G motherboard provides the performance and
feature set required for dual processor-based servers, with configuration
options optimized for communications, presentation, storage, computation or
database applications. The Intel E7520 (Lindenhurst) chipset consists of
the following components: the Lindenhurst Memory Controller Hub (MCH),
the 6300ESB (Hance Rapids) I/O Controller Hub (Hance Rapids ICH), and
the Intel PCI-X Hub (PXH).
The E7520 (Lindenhurst) MCH supports single or dual Nocona processors
with Front Side Bus speeds of up to 800 MHz(*Note). Its memory controller
provides direct connection to two channels of registered DDR266, DDR333
with a marched system bus address and data bandwidths of up to 5.4GB/
s. The Lindenhurst also supports the new PCI Express high speed serial I/
O i n t e r f a c e f o r s u p e r i o r I / O b a n d w i d t h . T h e M C H p r o v i d e s t h r e e
configurable x8 PCI Express interfaces which may alternatively be config-
ured as two independent x4 PCI Express interfaces. These interfaces sup-
port connection of the MCH to a variety of other bridges that are compliant
with the PCI Express Interface Specification, Rev. 1.0a.
6300ESB
(Hance Rapids) 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 Control-
ler, two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/
Flash BIOS Interface, PCI 2.3 Interface, and Integrated System Management
Controller.
6300ESB
(Hance Rapids) ICH System Features
The 6300ESB (Hance Rapids) ICH system consists of:
The I/O Controller Hub (Hance Rapids ICH) provides the I/O subsystem with
access to the rest of the system. Additionally, it integrates many I/O func-
tions.
The 6300ESB (Hance Rapids) 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 Management Controller.
