Dual-Channel Memory Population Rules
In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system
performance. Please refer to the following illustrations for population rules under
Dual-Channel mode.64x2=128  pin56x2=112  pin These DIMM slots are used for installing memory modules.

2-8 Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.Important
You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.Important
-DDR2 memory modules are not interchangeable with DDR and the DDR2
standard is not backwards compatible. You should always install DDR2
memory modules in the DDR2 DIMM slots.
-In Dual-Channel mode, make sure that you install memory modules of the
same type and density in different channel DIMM slots.
-To enable successful system boot-up, always insert the memory modules
into the DIMM1 first.VoltNotch7528v1.0CH2 Hardware Setup.p65  2008/2/1, 下午 04:308

This connector allows you to connect an ATX 24-pin power supply.
To connect the ATX 24-pin power supply, make sure the plug of the
power supply is inserted in the proper orientation and the pins are
aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin ATX power supply as you like. If you’d like
to use the 20-pin ATX power supply, please plug your power sup-
ply along with pin 1 & pin 13 (refer to the image at the right hand).

1. Make sure that all the connectors are connected to proper ATX power sup-
plies to ensure stable operation of the mainboard.
2. Power supply of 350 watts (and above) is highly recommended for system
stability.
3. ATX 12V power connection should be greater than 18A. ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.

If you install two IDE devices on the same cable, you must configure the
drives separately to master / slave mode by setting jumpers. Refer to IDE
device’s documentation supplied by the vendors for jumper setting
instructions.7528v1.0CH2 Hardware Setup.p65  2008/2/1, 下午 04:3012

2-14 Chassis Intrusion Connector: JCI1
This connector connects to the chassis intrusion switch cable. If the chassis is
opened, the chassis intrusion mechanism will be activated. The system will record
this status and show a warning message on the screen. To clear the warning, you
must enter the BIOS utility and clear the record. Fan Power Connectors: CPUFAN1, SYSFAN1~2
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.Important
1.Please refer to the recommended CPU fans at processor’s official website
or consult the vendors for proper CPU cooling fan.
2.CPUFAN1 / SYSFAN1 / SYSFAN2 supports fan control. You can adjust fan
speed in H/W Monitor menu of BIOS and install Dual Core Center utility
that will automatically control the CPU fan speed according to the actual
CPU temperature.
3. Fan cooler set with 3 or 4 pins power connector are both available for
