939Dual-VSTA is an ATX form factor (12.0-in x 9.6-in, 30.5 cm x 24.4 cm)
motherboard. Before you install the motherboard, study the configuration of your
chassis to ensure that the motherboard fits into it.
Pre-installation PrecautionsPre-installation Precautions
Pre-installation PrecautionsPre-installation Precautions
Pre-installation Precautions
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 anti-
static pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the motherboard
to the chassis, please do not over-tighten the screws! Doing so may
damage the motherboard.

Installation of CPU Fan and Heatsink
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 fas-
tened and in good contact with each other. Then connect the CPU fan to
the CPU FAN connector (CPU_FAN1, see Page 11, No. 3). For proper
installation, please kindly refer to the instruction manuals of the CPU fan

2.3 Installation of Memory Modules (DIMM)
939Dual-VSTA 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.11No.7) or identical DDRDIMM pair in Dual Channel B
(DDR3 and DDR4; Black slots; see p.11 No.8), 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.

(1) Populated Populated - -
(2) - - Populated Populated
(3)* Populated Populated Populated Populated
* For the configuration (3), please install identical DDRDIMMs in all four 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 Tech-
nology .

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force theDIMM into the
slot at incorrect orientation.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.

Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose pin1
and pin2 are “Short” when jumper cap is
placed on these 2 pins.

PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.11, No. 1) +5VSB (standby) for PS/2 or
USB wake up events.
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1 JL1 Jumper
(seep.11, No.27)
Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel
audio connectors can work.
Clear CMOS Jumper
(CLRTC1)
(seep.11, No.20)
Note: CLRTC1 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short pin2 and pin3
on CLRTC1 for 5 seconds. However, please do not clear the CMOS right after
you update the BIOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system first, and then shut it down
before you do the clear-CMOS action.
