939NF4G-SATA2 is a Micro ATX form factor (9.6-in x 8.8-in, 24.4 cm x 22.4 cm)
motherboard. Before you install the motherboard, study the configuration of your
chassis to ensure that the motherboard fits into it.
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
Before you install or remove any component, ensure that the
power is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
1.Unplug the power cord from the wall socket before touching any
component.
2.To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the carpet or
the like. Also remember to use a grounded wrist strap or touch a
safety grounded object before you handle components.
3.Hold components by the edges and do not touch the ICs.
4.Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component.
5.When placing screws into the screw holes to se cure the motherboard
to the chassis, please do not over-tighten the screws! Doing so may
damage the motherboard.

Step 1. Unlock the socket by lifting the lever up to a 90
o
angle.
Step 2. Position the CPU directly above the socket such that the CPU corner with
the golden triangle matches the socket corner with a small triangle.
Step 3. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU
into the socket to avoid bending of the pins.
Step 4. When the CPU is in place, press it firmly on the socket while you push
down the socket lever to secure the CPU. The lever clicks on the side tab
to indicate that it is locked.

After you install the CPU into this motherboard, it is necessary to install a
larger heatsink and cooling fan to dissipate heat. You also need to spray
thermal grease between the CPU and the heatsink to improve heat
dissipation. Make sure that the CPU and the heatsink are securely fastened and in good contact with each other. Then connect the CPU fan to
the CPU FAN connector (CPU_FAN1, see Page 9, No. 10). For proper
installation, please kindly refer to the instruction manuals of the CPU fan
and the heatsink.

2.3 Installation of Memory Modules (DIMM)2.3 Installation of Memory Modules (DIMM)
939NF4G-SATA2 motherboard provides four 184-pin DDR (Double Data Rate)
DIMM slots, and supports Dual Channel Memory Technology. For dual channel
configuration, you always need to install identical (the same brand, speed,
size and chip-type) DDR DIMM pair in the slots of the same color. In other words,
you have to install identical DDR DIMM pair in Dual Channel A (DDR1 and
DDR2; Blue slots; see p.9 No.6) or identical DDR DIMM pair in Dual Channel B
(DDR3 and DDR4; Black slots; see p.9 No.7), so that Dual Channel Memory
Technology can be activated. This motherboard also allows you to install four
DDR DIMMs for dual channel configuration, and please install identical DDR
DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration
Table below.
* For the configuration (3), plea se in stall identical DDR DIMM s in all f our slots.
1. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of blue slots
(DDR1 and DDR2), or in the set of black slots (DDR3 and DDR4).
2. If only one memory module or three memory modules are installed
in the DDR DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in DDR1
and DDR3, it is unable to activate the Dual Channel Memory Technology .
