WARNING!

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.

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.

1.Pull up the CPU socket lever and up to 90-degree angle.

2.Locate Pin 1 in the socket and look for a (golden) cut edge on the CPU

3. Press down the CPU socket lever	upper corner. Then insert the CPU
	into the socket.
and finish CPU installation.
Please make sure the CPU type is supported by the motherboard.
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.

Step1-2 : CPU Heat Sink Installation

English

1. Hook one end of the cooler bracket	2. Hook the other end of the cooler
to the CPU socket first.	bracket to the CPU socket.

Please use Intel approved cooling fan.

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.)

Make sure the CPU fan power cable is plugged in to the CPU fan connector, this completes the installation.

Please refer to CPU heat sink user’s manual for more detail installation procedure.

Step 2: Install memory modules

The motherboard has 3 dual inline memory module (DIMM) sockets. The BIOS will automatically detects memory type and size. To install the memory module, just push it vertically into the DIMM socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary between sockets.

Support Unbuffered DDR DIMM Sizes type:

64 Mbit (2Mx8x4 banks)	64 Mbit (1Mx16x4 banks)	128 Mbit(4Mx8x4 banks)
128 Mbit(2Mx16x4 banks)	256 Mbit(8Mx8x4 banks)	256 Mbit(4Mx16x4 banks)
512 Mbit(16Mx8x4 banks)	512 Mbit(8Mx16x4 banks)
Install memory in any combination table:
DDR1 (Bank 0&1)	DDR2 (Bank 2&3)	DDR3 (Bank 4&5)
SS	none	none
DS	none	none
SS	SS	none
DS	SS	none
DS	DS	none
SS	SS	SS
DS	SS	SS
DS	DS	SS
DS	DS	DS

SS: Single Side, DS: Double Side

Note:

1. GA-8STXC can only support 4 banks of DDR333.

2. If you mix DDR266 and DDR333 then all modules will run as DDR266.

DDR

1.The DIMM socket has a notch, so the DIMM memory module can only fit in one direction.

2.Insert the DIMM memory module vertically into the DIMM socket. Then push it down.

3.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.

When STR/DIMM LED is ON, do not install/remove DIMM from socket. Please note that the DIMM module can only fit in one direction due to the one notches. Wrong orientation will cause improper installation. Please change the insert orientation.

DDR Introduction

Established on the existing SDRAM industry 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 sensible evolutionary solution for the PC industry that builds on the existing SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock frequency. With peak bandwidth of 2.1GB per second, DDR memory enables system OEMs to build high performance and low latency DRAM subsystems that are suitable for servers, workstations, high-end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops and notebook applications.

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 AGP Card 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.
