When you installing AGP card, please make sure the following notice is fully understood and
practiced. If your AGP card has "AGP 4X/8X(1.5V) notch" (show below), please make sure your
AGP card is AGP 4X/8X(1.5V).
AGP 2X(3.3V) card is not supported by VIA K8T800 chipset. You might experience system unable
to boot up normally. Please insert an AGP 4X/8X(1.5V) card.

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.
Preparing 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.
The manufacturer assumes no liability for any damage, caused directly or indirectly, by improper
installation of any comfortable performing the installation, consult a qualified computer technician.
Damage to system components, and injury to yourself may result if power is applied during
installation.

Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification because
these specific bus frequencies are not the standard specifications for CPU, chipset and most of the
peripherals. Whether your system can run under these specific bus frequencies properly will
depend on your hardware configurations, including CPU, Chipsets, SDRAM, Cards…etc.

Step 1: Installing Processor and Heatsink
1.1 The installation of the processor and heatsink is performed in four main steps:
Step 1-1. Processor insertion
Step 1-2. Applying thermal grease
Step 1-3. Heatsink attachment
Step 1-4. Connecting processor fan power
These steps are described in detail in the following paragraphs.
Before installing the processor and heatsink, adhere to the following warning:
1. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.
2. Never force the processor into the socket.
3. Apply thermal paste between the processor and heatsink.
4. Please make sure the CPU type is supported by the motherboard.
5. If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause improper
installation. Please change the insert orientation. Please use AMD approved cooling
fan.
Step 1-1. First, check the processor pins to see that none are bent. Move the socket lever to the
unlocked position as shown in Figure 1 & Figure 2.(90 to the plane of the motherboard) prior to
inserting the processor. The A1 pin location is designated on the processor by a copper triangle that
matches up to a triangle on the socket as shown in Figure 3. Align the processor to the socket and
gently lower it into place. Do not force the processor into the socket.

a kind of tight , and then
continue pull the rod to 90-

Step1-2. When the processor is installed in the socket, apply thermal grease to the processor(as
shown in Figure 4) prior to installing the heatsink. AMD recommends using a high thermal
conductivity grease (such as Shin-Etsu types G751 or G749, or an equivalent product) for
the thermal interface material rather than a phase change material. Phase change materials
develop strong adhesive forces between the heatsink and processor.
Removing the heatsink under such conditions 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, or remove the cooling fan with extreme caution.)
Figure 4. 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 7.
Figure 7. 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 5&6.

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
recommended 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 2: Installing 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.
DDR
Notch
Fig.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.
Fig.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.

DDR Introduction
Established on the existing SDRAM infrastructure, DDR (Double Data Rate) memory is a high
performance and cost-effective solution that allows easy adoption for memory vendors, OEMs, and
system integrators.
DDR memory is a great evolutionary solution for the PC industry that builds on the existing SDRAM
architecture, yet make the awesome advances in solving the system performance bottleneck by doubling
the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/s of DDR400 memory and
complete line of DDR400/333/266/200 memory solutions, DDR memory is the best choice for building
high performance and low latency DRAM subsystem that are suitable for servers, workstations, and full
range of desktop PCs.

Step 3-1: AGP Card Installation
Step 3 Install expansion cards
1. Read the related expansion card's instruction document before install the expansion card into the computer.
2. Remove your computer's chassis cover, screws and slot bracket from the computer.
3. Press the expansion card firmly into expansion slot in motherboard.
4. Be sure the metal contacts on the card are indeed seated in the slot.
5. Replace the screw to secure the slot bracket of the expansion card.
6. Replace your computer's chassis cover.
7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.
8. Install related driver from the operating system.
Please carefully pull out the small white-drawable bar at the end of the AGP slot when you try
to install / uninstall the AGP card. Please align the AGP card to the onboard AGP slot and
press firmly down on the slot. Make sure your AGP card is locked by the small white-
drawable bar.
