Gigabyte GA-8I865PE-TW: Chapter 2 Hardware Installation Process

Step 2: Install memory modules

Before installing the memory modules, please comply with the following conditions:

1. Please make sure that the memory used is supported by the motherboard. It is

English

recommended that memory of similar capacity, specifications and brand be used.

2. Before installing or removing memory modules, please make sure that the computer

power is switched off to prevent hardware damage.

3. Memory modules have a foolproof insertion design. A memory module can be in-

stalled in only one direction. If you are unable to insert the module, please switch

the direction.

The motherboard supports DDR memory modules, whereby BIOS will automatically detect memory

capacity and specifications. Memory modules are designed so that they can be inserted only in

one direction. The memory capacity used can differ with each slot.

DDR

GA-8I865PE-TW 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-8I865PE-TW includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel A : DDR 1, DDR 2

Channel B : DDR 3, DDR 4

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

®

limitation of Intel

chipset specifications.

1. Only one DDR memory module is installed: The Dual Channel Technology can't operate when only

one DDR memory module is installed.

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.

3. Three DDR 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. Four DDR memory modules are installed: If you 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 two DDR memory modules into the DIMMs with the

same color in order for Dual Channel Technology to work.

The following tables include all memory-installed combination types:

(Please note that those types not in the tables will not boot up.)

- 13 - Hardware Installation Process

1. The DIMM slot has a notch, so the DIMM

memory module can only fit in one direction.

English

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.

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

AGP Card

the onboard AGP slot and press firmly down on the slot

.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.

1/2) ATX_12V/ATX (Power Connector)

With the use of the power connector, the power supply can supply enough stable power to all the

components on the motherboard. Before connecting the power connector, please make sure that all

components and devices are properly installed. Align the power connector with its proper location on

the motherboard and connect tightly.

The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power connector

is not connected, the system will not start.

Caution!

Please use a power supply that is able to handle the system voltage requirements. It is

recommended that a power supply that can withstand high power consumption be used (300W or

greater). If a power supply is used that does not provide the required power, the result can lead to an

unstable system or a system that is unable to start.
