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.

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 fas-
tened and in good contact with each other. Then connect the CPU fan to
the CPU FAN connector (CPU_FAN1, see Page 10, No. 3). For proper
installation, please kindly refer to the instruction manuals of the CPU fan
and the heatsink.

939SLI-eSATA2 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.10 No.7) or identical DDR DIMM pair in Dual Channel B
(DDR3 and DDR4; Black slots; see p.10 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
DDR1DDR2DDR3DDR4
(Blue Slot)(Blue Slot)(Black Slot)(Black Slot)
(1)Populated Populated --
(2)- - PopulatedPopulated
(3)*PopulatedPopulatedPopulatedPopulated
* 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 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 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.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.

There are 1 Future CPU Port, 3 PCI slots and 3 PCI Express slots on 939SLI-eSATA2
motherboard.
Future CPU Port (Yellow-Colored Port):
Future CPU Port allows you to upgrade your AMD K8 939-Pin CPU to AM2 940-Pin
CPU by installing an add-on ASRock AM2CPU Board into this future CPU Port on
939SLI-eSATA2 motherboard. Before you upgrade the K8 939-Pin CPU to AM2 940-
Pin CPU, it is necessary to adjust the jumper settings for those required jumpers on
939SLI-eSATA2 motherboard. Please refer to the table below for the correct jumper
settings.
This yellow-colored Future CPU Port is not an AGP slot! Please do
NOT insert any AGP card into it!
