Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
2. To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the car-
pet 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 antstatic pad or in the bag that comes with the
component.
5. When placing screws into the screw holes to secure the
motherboardto the chassis, please donot over-tightenthe screws!
Doing so may damage the motherboard.

Step 1. Unlock the socket by lifting the lever up to a 90° 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.
Step 5. Install CPU fan and heatsink. For proper installation, please kindly refer to
the instruction manuals of your CPU fan and heatsink vendors.

2.2 Installation of Memory Modules (DIMM)2.2 Installation of Memory Modules (DIMM)
2.2 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)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.2No.7) or identical DDRDIMM pair in Dual Channel B
(DDR3 and DDR4; Black slots; see p.2 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.
Dual Channel Memory Configurations
DDR1 DDR2 DDR3 DDR4
(Blue Slot) (Blue Slot) (Black Slot) (Black Slot)
(1) Populated Populated - -
(2) - - Populated Populated
(3)* Populated Populated Populated Populated
* For the configuration (3), please install identical DDR DIMMs 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 .

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
STEP1: Unlock a DIMM slot by pressing the retaining clips outward.
STEP2: Align a DIMM on the slot such that the notch on the DIMM 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 the DIMM into the
slot at incorrect orientation.
STEP3: Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and theDIMM is properly seated.

PCIE2 (PCIE x1 slot) is used for PCI Express cards with x1 lane
width graphics cards, such as Gigabit LAN card, SATA2 card, etc.
AGP slot: TheAGP slot is used to install a graphics card. TheASRock AGP slot has
a special design of clasp that can securely fasten the inserted graphics
card.
Please do NOT use a 3.3V AGP card on the AGP slot of this
motherboard! It may cause permanent damage! For the voltage infor-
mation of your AGP card, please check with the AGP card vendors.

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)
(see p.2, 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.

Installation
This motherboard adopts JMicron JMB360 chipset that supports Serial ATAII
(SATAII) hard disk. It also adopts ULi®M1567 south bridge chipset that supports
Serial ATA (SATA) hard disks, and supports RAID functions. You may install SATA /
SATAII hard disks on this motherboard for internal storage devices. This section
will guide you to install the SATA / SATAII hard disks.
STEP1: Install the SATA / SATAII hard disks into the drive bays of your chassis.
STEP2: Connect the SATA power cable to the SATA / SATAII hard disk.
STEP3: Connect one end of the SATA data cable to the motherboard’s SATA /
SATAII connector.
STEP4: Connect the other end of the SATA data cable to the SATA / SATAII hard
disk.
1. If you plan to use RAID 0, RAID 1, or JBOD functions on SATA, SATA
HDDs must be operated in “RAID” mode.
2. “RAID” and “non-RAID” mode are options under “SATA Operation Mode” in
BIOS setup. Please refer to page 35 of “User Manual” in the support CD
for details. They need different drivers during actual operation.

939Dual-VSTA motherboard supports Hot Plug and Hot Swap functions for SATA /
SATAII Devices.
NOTE
What is Hot Plug Function?
If the SATA / SATAII HDDs are NOT set for RAID configuration, it is called
“Hot Plug” for the action to insert and remove the SATA / SATAII HDDs
while the system is still power-on and in working condition.
However, please note that it cannot perform Hot Plug if the OS has been
installed into the SATA / SATAII HDD.
What is Hot Swap Function?
If SATA / SATAII HDDs are built as RAID1 then it is called “Hot Swap” for
the action to insert and remove the SATA / SATAII HDDs while the system
is still power-on and in working condition.
