10. S/PDIF (Sony/Philips Digital Interface) Connector
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides
impressive audio quality through optical fiber and allows you to enjoy digital audio instead of
analog audio. Normally there are two S/PDIF outputs as shown, one for RCA connector, the
most common one used for consumer audio products, and the other for optical connector
with better audio quality. Through a specific audio cable, you can connect the S/PDIF
connector to other end of the S/PDIF audio module, which bears S/PDIF digital output.
However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF digital
input to connect to the S/PDIF digital output to make the most out of this function.

11. Super 5.1 Channel Audio Effects
This motherboard comes with an ALC650 CODEC, which supports high quality of 5.1
Channel audio effects, bringing you a brand new audio experience. On the strength of the
innovative design of ALC650, you're able to use standard line-jacks for surround audio output
without connecting any external module. To apply this function, you have to install the audio
driver in the Bonus Pack CD as well as an audio application supporting 5.1 Channel. Picture
bellow represents the standard location of all speakers in 5.1Channel sound track. Please
connect the plug of your front speakers to the green "Speaker out" port, rear speakers' plug
to the blue "Line in" port and both of the center and subwoofer speakers to the red "MIC in"
port.

12. Installing Memory Modules
Although Intel claims that 845GE Chipsets only support two DIMM sockets (four banks), we
overcome this obstacle with special circuit design in order to provide better adaptability for
different combinations of various RAM modules. On this motherboard, DIMM1 occupies the
1st and 2nd banks; both DIMM2 and DIMM3 are designed to share the 3rd and 4th banks.
Thus, maximally you can insert one double side RAM module on DIMM2 or DIMM3, or
insert one single side module on both DIMM2 and DIMM3 the most. After our testing and
verifying, the following configurations are approved to be running properly.

13. Support Six USB2.0 Connectors
This motherboard provides six USB2.0 connectors. Compared to traditional USB 1.0/1.1 with
the speed of 12Mbps, USB 2.0 has a fancy speed up to 480Mbps, which is 40 times faster
than the traditional one.
