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.

2.3 Installation of Memory Modules (DIMM)
939NF6G-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) DDRDIMM 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.10No.6) or identical DDRDIMM pair in Dual Channel B
(DDR3 and DDR4; Black slots; see p.10 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.

(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 inDDR1
and DDR3, it is unable to activate the Dual Channel Memory Tech-
nology .

2.5 Easy Multi Monitor Feature
This motherboard supports Multi Monitor upgrade. With the internal onboard VGA
and the external add-on PCI Express VGA card, you can easily enjoy the benefits
of Multi Monitor feature. Please refer to the following steps to set up a multi
monitor environment:
1. Install theNVIDIA®PCI Express VGA card to PCIE1 (PCIE x16 slot). Please refer
to page 16 for proper expansion card installation procedures for details.
2. Connect the D-Sub input monitor cable to the VGA/D-Sub port on the I/O panel
of this motherboard. Connect another D-Sub input monitor cable to the
VGA/D-Sub connector of the add-on PCI Express VGA card. Connect the DVI-D
input monitor cable to the VGA/DVI-D connector of the add-on PCI Express VGA
card.
3. Boot your system. Press <F2> to enter BIOS setup. Enter “Share Memory”
option to adjust the memory capability to [16MB], [32MB], [64MB], [128MB], or
[256MB] to enable the function of onboard VGA/D-sub. Please make sure that
the value you select is less than the total capability of the system memory. If
you do not adjust the BIOS setup, the default value of “Share Memory”, [Auto],
will disable onboard VGA/D-Sub function when the add-on VGA card is
inserted to this motherboard.
4. Install the onboard VGA driver to your system. If you have installed the
onboard VGA driver already, there is no need to install it again.
5. Set up a multi-monitor display. Right click the desktop, choose “Properties”, and
select the “Settings” tab so that you can adjust the parameters of the multi-
monitor according to the steps below. (The item names and operation
procedures described in this step are under Windows®XP environment. If you
install other Windows®OS, the item names and operation procedures may be
similar.)
A. Click the “Identify” button to display a large number on each monitor.
B. Right-click the display icon in the Display Properties dialog that you wish to
be your primary monitor, and then select “Primary”. When you use multiple
monitors with your card, one monitor will always be Primary, and all
additional monitors will be designated as Secondary.
C. Select the display icon identified by the number 2.
D. Click “Extend my Windows desktop onto this monitor”.
E. Right-click the display icon and select “Attached”, if necessary.

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.

(see p.10, 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.
Clear CMOS Jumper
(CLRCMOS1)
(seep.10, No. 21)
Note: CLRCMOS1 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 CLRCMOS1 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.
