Gigabyte GA-7S748, GA-7S748-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(3.3V) card is not supported by SiS® 748. You might experience system unable to boot up normally. Please insert an AGP 4X/8X(1.5V) 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-7S748 Series (or any AGP 4X only) motherboards might not function properly, if you install this card without switching the jumper to 4X(1.5V) 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-7S748 Series (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® 748 based motherboards.

WARNING!

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protectthem 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 supplycase.

3.Hold components by the edges and trynot touch the IC chips, leads or connectors, or othercomponents.

4.Place components on a grounded antistatic pad or on the bag thatcame 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 theATX power connector on the motherboard.

Installing the motherboard to the chassis…

Ifthemotherboard has mounting holes,buttheydon’t lineup with the holeson the base andthere are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting holes. Just cutthe bottom portion ofthe spacers (the spacer maybe 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 mayneed 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 anyprinted circuit write or parts on the PCB that are near the fixing hole, otherwise itmay damage the boardor cause boardmalfunctioning.

Please set the CPU host frequencyin 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, chipsetand most of the peripherals. Whether your system can run under these specific bus frequencies properly will depend on your hardware configurations, including CPU, Chipsets, Memory, Cards… .etc.

Step 2: Install memory modules

Before installing the memory modules, adhere to the following warning:

1.When RAM_LEDis 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 notch. Wrong orientation will cause improper installation. Please change the insertorientation.

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 Slot. The DIMM module can onlyfit in one direction due to the notch. Memorysize can varybetween sockets.

Hardware Installation Process

English

1. The DIM M slot has a notch, so the DIM M mem ory

module can only fit in one direction.

2. Insert the DIM M 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) memoryis a high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs, and system integrators.

DDR memory is a great evolutionarysolution for the PC industry that builds on the existing SDRAM architecture, yetmake the awesome advances in solving thesystem performance bottleneck bydoubling the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/s of DDR400 memory and complete line ofDDR400/333/266/200 memorysolutions, DDR memory is the bestchoice for building high performance and low latencyDRAM subsystem that are suitable for servers, workstations, and full range of desktop PCs.
