Prepare your computer...
Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have one,
touch both of your hands to a safely grounded object or to a metal object, such as the power
supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or other
components.
4. Place components on a grounded antistatic pad or on the bag that came with the components
whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or remove the ATX power
connector on the motherboard.
Installing the motherboard to the chassis...
If the motherboard has mounting holes, but they don't line up with the holes on the base and there
are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the
mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so
be careful of your hands). In this way you can still attach the motherboard to the base without worrying
about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the
motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the
screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it
may damage the board or cause board malfunctioning.

GA-K8VNXP-939/GA-K8V Ultra-939 Motherboard
English
Step 1: Install the Central Processing Unit (CPU)
Before installing the CPU, please comply with the following conditions:
Socket Lever
The installation of the processor and cooling fan is performed in four main steps:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the
wrong direction, the CPU will not insert properly. If this occurs, please change the insert
direction of the CPU.
3. Please add an even layer of heat sink paste between the CPU and heatsink.
4. Please make sure the heatsink is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It is
not recommended that the system bus frequency be set beyond hardware specifications
since it does not meet the required standards for the peripherals. If you wish to set the
frequency beyond the proper specifications, please do so according to your hardware
specifications including the CPU, graphics card, memory, hard drive, etc.
Step1-1. First, check the processor pins to see that none are bent. Move the socket lever to the
unlocked position as shown in Figure 1.(90oto the plane of the motherboard) prior to inserting
the processor. The pin 1 location is designated on the processor by a copper triangle that
matches up to a triangle on the socket as shown in Figure 2. Align the processor to the socket
and gently lower it into place. Do not force the processor into the socket.
Figure 1.
Pull the lever to the 90-degree directly.
Figure 2.
Pin 1 location on the Socket and Processor. Move the
socket lever to the locked position while holding pressure
on the center of the processor.

Step1-2. When the processor is installed in the socket, apply thermal grease to the processor(as shown
in Figure 3) prior to installing the heatsink. Phase change materials develop strong adhesive
forces between the heatsink and processor. Removing the heatsink under such condi-
tions can cause the processor to be removed from the socket without moving the
socket lever to the unlocked position and then damage the processor pins or socket
contacts.
** We recommend you to apply the thermal tape to provide better heat conduction between
your CPU and heatsink. (The CPU cooling fan might stick to the CPU due to the hardening of
the thermal paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the processor.
To avoid this from happening, we suggest you to either use thermal tape instead of thermal
paste, orremove the cooling fan with extreme caution.)
Figure 3.
Application of thermal grease to the processor.
Step 1-4. Connect the fan power wires to the header on the motherboard as shown in Figure 6.
Figure 6.
Connecting the fan power wires.
Step 1-3.Once the thermal grease has been applied to the processor, the heatsink can be attached to
the processor. Align the heatsink assembly with the support frame mating with the backer plate
standoffs as shown in Figure 4 & 5.

Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is recom-
mended that memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be installed
in only one direction. If you are unable to insert the module, please switch the direction.
Step 3: Install Memory Modules
The motherboard supports DDR memory modules, whereby BIOS will automatically detect memory
capacity and specifications. Memory modules are designed so that they can be inserted only in one
direction. The memory capacity used can differ with each slot.

Notch
1. To attach Cool-Plus
to a heatsink, align the
extensions on both
sides with the grooves
in the heatsink as
shown. Firmly press
down until it snaps into
position.
2. Once the fan is prop-
erly affixed onto the
heatsink, plug the
power cable into the
NB_FAN connector.
Before proceeding, first check to make
sure that the fan's power cable is
disconnected. Then, while applying
pressure to the top of the fan, carefully
use a screwdriver to dislodge the
extension on one side.
Exerting too much pres-
sure on the fan during
removal might cause
the side extensions to
break-off.

Dual Channel DDR:
The GA-K8VNXP-939/GA-K8V Ultra-939 supports the Dual Channel Technology. When the Dual
Channel Technology is activated, the bandwidth of memory bus will be double the original one.
Due to CPU limitation, if you want to operate the Dual Channel Technology, please follow the guidelines
below for Dual Channel memory configuration.
1. Dual Channel mode will not be enabled if only one DDR memory module is installed.
2. To enable Dual Channel mode with 2 memory modules (it is recommended to use memory
modules of identical brand, size, chips, and speed), you must install them into DIMM sockets
of the same color.
3. To enable Dual Channel mode with 4 memory modules, it is recommended to use memory
modules of identical brand, size, chips, and speed.
The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side)
1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction. Insert the DIMM memory
module vertically into the DIMM socket. Then push it down.
2. Close the plastic clip at both edges of the DIMM sockets to
lock the DIMM module.
Reverse the installation steps when you wish to remove
the DIMM module.
