ASUS DSAN-DX 1-3
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.
