Introduction
Features
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the sys-
tem at the set time interval. If the system hangs or fails to function, it will reset
at the set time interval so that your system will continue to operate.
DDR2
DDR2 is a higher performance DDR technology whose data transfer rate delivers
bandwidth of 4.3 GB per second and beyond. That is twice the speed of the con-
ventional DDR without increasing its power consumption. DDR2 SDRAM modules
work at 1.8V supply compared to 2.6V memory voltage for DDR modules. DDR2
also incorporates new innovations such as the On-Die Termination (ODT) as well
as larger 4-bit pre-fetch against DDR which fetches 2 bits per clock cycle.
PCI Express Gen 2
PCI Express Gen 2 is a high bandwidth I/O infrastructure that possesses the abil-
ity to scale speeds by forming multiple lanes. The x16 PCI Express lane supports
transfer rate up to 5Gb/s.
Integrated Graphics
The northbridge chip comes integrated with the ATI Radeon TM HD3200 graphics
core delivering exceptional 3D graphics performance. It supports DVI interface.
DVI
DVI (Digital Visual Interface) is a form of video interface technology made to
maximize the quality of flat panel LCD monitors and modern video graphics
cards. Data is transmitted using the TMDS (Transition Minimized Differential Sig-
naling) protocol, providing a digital signal from the PC’s graphics subsystem to
the display.
8CH High Definition Audio
The onboard Realtek ALC885 is a High Definition audio codec and the 6 audio
jacks at the rear I/O panel provides 8-channel audio output for advanced 7.1-
channel super surround sound audio system.
