Hardware Setup
CPU (Central Processing Unit)
When you are installing the CPU, make sure that you install the cooler to prevent the
CPU from overheating. If you do not have a CPU cooler, contact your dealer to
purchase and install them before turning on the computer.
Important
1. Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheating.
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)
between the CPU and the heatsink to enhance heat dissipation.
3. While replacing the CPU, always turn off the power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the
safety of CPU.

64x2=128 pin56x2=112 pin
Installing Memory Modules
1. Locate the DIMM slots on the mainboard. Flip open the retaining clip at each side
of the DIMM slot.
2. Align the notch on the DIMM with the key on the slot. Insert the DIMM vertically into
the DIMM slot. Then push it in until the golden finger on the DIMM is deeply inserted
in the DIMM slot. The retaining clip at each side of the DIMM slot will automatically
close if the DIMM is properly seated.
Important
You can barely see the golden finger if the DIMM is properly inserted in the
DIMM slot.
3. Manually check if the DIMM has been locked in place by the retaining clips at the
sides.
4. Follow the same procedures to install more DIMMs if necessary.

Fan Power Connector: CPU_FAN1, SYS_FAN1 / 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 onboard, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
