can also plug it on SYSFAN2 or SYSFAN3 connector.

5. Setting CPU Voltage & Frequency

4. JP20 K7 Host Clock Selection

3. Installing CPU & Housing Fan

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, i

you are not an over-clocker, we recommend you to set it to the default setting. Additionally,

this motherboard also provides “1MHz Stepping Adjustment” feature for overclockers to

adjust CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment

range has four levels: 100~129, 130~160,161~191 and 200-250MHz for your choosing. I

you fix the CPU FSB frequency by JP20, the “1MHz Stepping Adjustment” range will be

changed and following the JP20 setting.

Note: Some CPU fans do not have

sensor pin, so that cannot support

fan monitorin

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be

automatically detected and the range is from 1.1V to 1.85V. It is not

necessary to set CPU Core Voltage

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency

through the BIOS setup, and no jumpers or switches are needed.

13. Super 5.1 Channel Audio Effect

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 5.1 Channels

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 subwoofe

speakers to the red “MIC in” port.

12. S/PDIF 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 o

analog audio. Through a specific audio cable, you can connect the S/PDIF connector to othe

end of the S/PDIF audio module, which bears S/PDIF digital output. Normally there are two

S/PDIF outputs as shown, one for RCA connector, the most common one used for consume

audio products, and the other for optical connector with better audio quality. Same as outputs,

you can also connect RCA or optical audio products to input connectors on the module and

have the voice or music come out from your computer. However, you must have a S/PDIF

supported speaker/amplifier/decoder with S/PDIF digital input/output to connect to the S/PDIF

digital input/output to make the most out of this function.
