6. Installing Memory Modules

Although Intel claims that 845E 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
st nd
1 and 2 banks; both DIMM2 and DIMM3 are designed to share the 3
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.

7. Super 5.1 Channel Audio Effect

This motherboard comes with an ALC650 CODEC which supports high quality of 5.1 Channel audio
effect, 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 Channel 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.

and 4 banks.
most common one used for consumer audio products, and the other for optical connector
with a even better audio quality. Through a specific audio cable, you can connect the
S/PDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However, you
must have a S/PDIF supported speaker with S/PDIF digital input to make the most of this
function.
