1-2 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWU
motherboard provides the performance and feature set required for quad-processor
or dual-processor-based high-end systems with confi guration options optimized for
complex storage platforms. The 5400 chipset supports single or dual Intel Quad-
Core/Dual-Core Xeon 5400 Series/5300LV Series/5200 Series/5100LV Series
processor with front side bus speeds of up to 1.6 GHz. The chipset consists of the
5400 Memory Controller Hub (MCH) for the host bridge and the 631xESB/632xESB
I/O Controller Hub (Enterprise South Bridge 2-ESB2) for the I/O subsystem.
The Intel 5400 MCH (North Bridge)
The 5400 MCH (North Bridge) provides two FSB processing interfaces, four fully
buffered (FBD) DIMM memory channels, PCI-Express bus interfaces confi gurable
to form x8 or x16 ports, an EB2 South Bridge Interface (ESI) and SMBus Interfaces
for system management, and DIMM Serial Presence Detect (SPD). The peak band-
width for each FBD channel is 8 GB/s for DDR2 800/667/533 FBD memory. The
PCI-Express interfaces can be confi gured to form x8 or x16 ports that can operate
up to Gen-2 speeds in x16 confi guration for enhanced graphics applications.
The Intel 631x/632x ESB I/O Controller Hub-ESB2 (South
Bridge)
The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates
an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host
controller, fi ve external USB 2.0 ports, an LPC interface controller, and a fl ash
BIOS interface controller. Additionally, the ESB 2 chip also contains a PCI interface
controller, integrated LAN controller, an ASF controller and an ESI for communica-
tion with the MCH. The Intel ESB2 offers the data buffering and interface arbitration
capabilities required for a high-end system to constantly operate effi ciently and
maintain peak performance.
Compliant with the ACPI platform, the ESB2 supports the Full-On, Stop-Grant, Sus-
pend-to-RAM, Suspend-to-Disk, and Soft-Off power management states. Combined
with the functionality offered by the onboard LAN controller, the ESB2 also supports
alert systems for remote management.
With the 5400 chipset built in, the X7DWU offers a superb solution for intense com-
puting and complex I/O environments, and is ideal for high-end server systems.
