Gigabyte GA-8GEMT4: Chapter 2 Hardware Installation Process

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.

English

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 2.664GB 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, necessary 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.

When an AGP 2X (3.3V) card is installed the 2X_DET will light up, indicating a

non-supported graphics card is inserted. Informing users that system might not boot up

normally due to AGP 2X (3.3V) is not supported by the chipset.
