WARNING!

English

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.

Installing the motherboard to the chassis…

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.

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 A TX power supply is switched of f before you plug in or remove the A TX power connector on the motherboard.

If the motherboard has mounting holes, but they don't line up with the holes on the base and there

4. Locate Pin 1 in the socket and look for a (golden) cut edge on the CPU upper corner. Then insert the CPU into the socket.

- 12 -GA-8VT880 Series Motherboard

Step 1-2 : CPU Cooling Fan Installation

Before installing the CPU Cooling Fan , adhere to the following warning:

1. Please use Intel approved cooling fan.

2. We recommend you to apply the thermal tape to provide better heat conduction between your CPU and cooling fan. (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.)

3. Make sure the CPU fan power cable is plugged in to the CPU fan connector, this completes the installation. Please refer to CPU cooling fan user's manual for more detail installation procedure.

English

1. Fasten the cooling fan supporting-base onto the CPU socket on the mainboard.

2. Make sure the CPU fan is plugged to the CPU fan connector, than install complete.

- 13 - Hardware Installation Process

Step 2: Install memory modules

English

The motherboard has 4 dual inline memory module (DIMM) sockets. The BIOS will automatically detects memory type and size. T o 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.

Before installing the processor and heatsink, adhere to the following warning:

1.When RAM_LED is ON, do not install/remove DIMM from socket.

2.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.

Notch

DDR

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

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

3. Close the plastic clip at both edges of the DIMM slots 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.

Dual Channel DDR:

GA-8VT880 Series supports Dual Channel Technology. When Dual Channel Technology is activated, the bandwidth of memory bus will be double the original one, with the fastest speed at 6.4GB/s DDR400. GA-8VT880 Series includes four DIMM slots, and each Channel has 2 DIMMs as following:

Channel A : DIMM 1, 2 Channel B : DIMM 3, 4

Below are the explanations:

1. One, or three memory modules are installed: The Dual Channel Technology will not operate when one, three, memory modules are installed and they will only work as Single Channel.

2. Two DDR memory modules are installed (the same memory size and type): The Dual Channel Technology will operate when two DDR memory modules are inserted individually into Channel A and Channel B (DIMM 1 pairs up with DIMM 3, DIMM 2 and DIMM 4). However, if the two DDR memory modules are inserted into the same Channel (DIMM 1,2 or DIMM 3,

4) then Dual Channel Technology will not operate.

3. Three memory modules are installed: Please note that The Dual Channel Technology will not operate when three DDR memory modules are installed; part of them will not be detected.

4. If four DDR memory modules are installed (two pairs of DDR memory modules with the same memory size and type): The Dual Channel Technology will operate when a pair of DDR memory modules are inserted into DIMM1, 3 and another pair into DIMM 2,4.
