Gigabyte GA-8S655FX ULTRA, GA-8S655FX-L User Manual

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 4X/8X notch

Caution: AGP 2X card is not supported by SiS® 655FX. You might experience system unable to boot up normally. Please insert an AGP 4X/8X card.

Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X(1.5V) mode by adjusting the jumper. The factory default for this card is 2X(3.3V). The GA-8S655FX Ultra/GA-8S655FX (-L)

(or any AGP 4X only) motherboardsmight not function properly, if you install this card without switching the jumper to 4X(1.5) mode in it.

Example 2: Some ATi Rage 128 Pro graphics cards made by "Power Color", the graphics card manufacturer & some SiS 305 cards, their golden finger is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but they support 2X(3.3V) only. The GA-8S655FX Ultra/GA-8S655FX (-L) (or any AGP 4X only) motherboards might not function properly, If you install this card in it.

Note : Although Gigabyte's AG32S(G) graphics card is based on ATi Rage 128 Pro chip, the design of AG32S(G) is compliance with AGP 4X(1.5V) specification. Therefore, AG32S (G)will work fine with SiS® 655FX based motherboards.

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them againstdamage 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 safelygrounded object or to a metal object, such as the power supplycase.

3.Hold components by the edges and try nottouch 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 ower 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 ofthe spacers (the spacer may be a little hard to cut off, so be careful ofyour 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 circuitwrite or parts on the PCB thatare near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

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 fanuser's manual for more detail installation procedure.

Step 2: Install memory modules

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

When RAM_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.

The motherboard has 4 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.

Notch

DDR

GA-8S655FX Ultra/GA-8S655FX(-L) supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add double up to 6.4GB/s.

GA-8S655FX Ultra/GA-8S655FX(-L) includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel A : DIMM 1, DIMM 2

Channel B : DIMM 3, DIMM 4

If you want to operate the Dual Channel Technology, please note the following explanations due

to the limitation of SiS® chipset specifications.

1.One/three DDR memory module is installed: The Dual Channel Technology can't operate when only one or three DDR memory module is installed.

GA-8S655FX Series Motherboard

- 14 -

2.Two DDR memory modules are installed (the same memory size and type): The Dual Channel Technology will operate when two memory modules are inserted individually into Channel A and B. If you install two memory modules in the same channel, the Dual Channel Technology will not operate. Additionally, you can boot the system only when one of the memory modules is inserted into Channel A or Channel B. On the other hand, the memory module must be inserted into any sockets.

3.Four DDR memory modules are installed: Ifyou install four memory modules at the same time, the Dual Channel Technology will operate only when those modules have the same memory size and type.

We'll strongly recommend our user to slot into two DDR memory modules into the DIMMs with the same color in order for Dual Channel Technology to work.

The following table is for Dual Channel Technology combination:

Hardware Installation Process

English

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.
