1-2 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWN+
motherboard provides the performance and feature set required for quad-pro-
cessor 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
bandwidth for each FBD channel is 8 GB/s for DDR2 800/667 FBD memory, giving
a total memory size of 128 MB for 4 FBD channels. 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 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 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, Azalia/'97 digital controller, integrated LAN controller, an ASF control-
ler 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 X7DWN+ offers a superb solution for intense
computing and complex I/O environments, and is ideal for high-end server sys-
tems.
