Gigabyte GA-8IGX: Chapter 2 Hardware Installation Process

GA-8IGX Motherboard

DDR

1. The DIMM slot has a notch, so the

DIMMmemory module can only fit in one direction.

2. Insert the DIMM memory module verticallyinto the

DIMM slot. Then push it down.

3. Close the plastic clip at both edges of theDIMM 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 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.

 When STR/DIMM LED is ON, you do not install / remove DDR from socket.

 Please note that the DIMM module can only fit in one direction due to

the two notches. Wrong orientation will cause improper installation.

Please change the insert orientation.

Hardware Installation Process

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 .

AGP Card

Make sure your AGP card is locked by the

small white- drawable bar.
