PCI Express™ interface

The motherboard fully supports PCI Express, the latest I/O interconnect technology

that speeds up the PCI bus. PCI Express features point-to-point serial

interconnections between devices and allows higher clockspeeds by carrying data

in packets. This high speed interface is software compatible with existing PCI or

PCI-X specifications.

Broadcom 5721 LAN solution

The motherboard comes with a dual-port Broadcom 5721 network connection

to provide a total solution for your networking needs. Refer to page 2-28 for the

location of the LAN ports and section 2.6 Jumpers for details on Gigabit LAN

settings.

Serial ATA II technology

The motherboard supports the Serial ATA II 3 Gb/s technology through ICH9R

Serial ATA interfaces. The Serial ATA II specification provides twice the bandwidth

of the current Serial ATA products with a host of new features, including Native

Command Queuing (NCQ), Power Management (PM) Implementation Algorithm,

and Hot Swap. Serial ATA allows thinner, more flexible cables with lower pin count

and reduced voltage requirements.

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0 specification,

dramatically increasing the connection speed from the 12 Mbps bandwidth on USB

1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the W83793G chip to prevent overheating

and damage. The system fan rotations per minute (RPM) is monitored for timely

failure detection. The chip monitors the voltage levels to ensure stable supply of

current for critical components.
