Introduction
Features
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.
8CH High Definition Audio
The onboard Realtek ALC885 is a High Definition audio codec and the 6 au-
dio jacks at the rear I/O panel provides 8-channel audio output for advanced
7.1-channel super surround sound audio system. ALC885 also supports S/PDIF
output, allowing digital connections with DVD systems or other audio/video mul
-
timedia.
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital audio sig-
nals 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 interface on the system board
sends surround sound and 3D audio signal outputs to amplifiers and speakers
and to digital recording devices like CD recorders.
Serial ATA with RAID
Serial ATA is a storage interface that is compliant with SATA 1.0 specification.
It supports speed of up to 3Gb/s. Serial ATA 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
0/1/0+1(10)/5.
Gigabit LAN
The JMC250 PCI Express Gigabit LAN chip supports up to 1Gbps data rate.
