1-2 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWA-N
motherboard provides the performance and feature set required for quad-core-
processor- or dual-core-processor-based high-end workstations with confi guration
options optimized for complex system platforms. The 5400 chipset supports single
or dual Intel Quad-Core/Dual-Core Xeon 5400/5300/5200/5100 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 x4 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 PCI-Express x4 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 631xESB/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, six USB 2.0 ports, an LPC interface controller, and a fl ash BIOS inter-
face controller. Additionally, the ESB 2 chip also contains a PCI interface controller,
Azalia/'97 digital controller, integrated LAN controller, an ASF controller and an
ESI for communication 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,
Suspend-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 X7DWA-N offers a superb solution for intense
computing and complex I/O environments, and is ideal for high-end server sys-
tems.
