Memory
The DIMM slot is intended for system memory modules.
Installing Memory Modules
1. Locate the SO-DIMM slot on the mainboard.
2. Align the notch on the DIMM with the key on the slot. Insert the DIMM at a 45
degrees into the SO-DIMM slot. Then push it in until the golden finger on the
DIMM is deeply inserted in the SO-DIMM slot. Push the module towards the
board until it is horizontal with the board.
3. Manually check if the DIMM has been locked in place by the retaining clips at
the sides.

Connector
IDE Connector: IDE1
This connector supports IDE hard disk drives, optical disk drives and other IDE
devices.
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.
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.

Serial ATA Connector: SATA1, SATA2
This connector is a high-speed Serial ATA interface port. Each connector can
connect to one Serial ATA device.
Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, data
loss may occur during transmission.
SPI Flash ROM Header: JSPI1
This header is used to flash SPI flash ROM.
Fan Power Connector: CPUFAN1
The fan power connector supports 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 onboard, you must
use a specially designed fan with speed sensor to take advantage of the CPU fan
control.
