Features
The Watchdog Timer function allows your
application to regularly “clear” the system 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.
DDR3 delivers increased system bandwidth and im-
proved performance. It offers peak data transfer rate
of up to 21 Gb/s bandwidth. The advantages of DDR3 are its
higher bandwidth and its increase in performance at a lower power
than DDR2.
The Intel northbridge chip comes integrated with the
Intel Graphics Media Accelerator 4500 delivering an
excellent blend of graphics performance and features to meet
business needs. With support for Microsoft DirectX 10, Shader
Model 4.0 and OpenGL* 2.0, Intel GMA 4500 delivers excellent
video and 3D graphics with outstanding graphics responsiveness.
These enhancements deliver the performance and compatibility
needed for today’s and tomorrow’s business applications.
S/PDIF is a standard audio file transfer format that
transfers digital audio signals to a device without
having to be converted first to an analog format. This prevents the
quality of the audio signal from degrading whenever it is converted
to analog. S/PDIF is usually found on digital audio equipment such as
a DAT machine or audio processing device. The S/PDIF connector on
the system board sends surround sound and 3D audio signal out-
puts to amplifiers and speakers and to digital recording devices like
CD recorders.
Serial ATA is a storage interface that is compliant
with SATA 1.0a specification. With speed of up to
3Gbps, it improves hard drive performance faster than the standard
parallel ATA whose data transfer rate is 100MB/s. The system board
allows configuring RAID on Serial ATA devices. It supports RAID 0,
RAID 1, RAID 0+1 and RAID 5.
