Gigabyte GA-8IHXP 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 notch"(show below), please make sure your AGP card is AGP 4X (1.5V).

Do not use AGP 2X card (3.3V) in this motherboard. It will

burn and damage the motherboard due to Intel® 845(E/G) / 850(E) chipset can't support AGP 2X(3.3V).

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). If you install this card in GA-8IHXP(or any AGP 4X only) motherboards without switching the jumper to 4X mode (1.5V), it will burn the motherboard.

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/4X mode AGP slot, but they support 2X(3.3V) only. If you install this card in GA-8IHXP (or any AGP 4X only) motherboards, it will burn the motherboard.

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 Intel® 845(E/G) / 850(E) based motherboards.

WARNING!

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them 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 supply case.

3.Hold components by the edges and try not touch 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

power connector on the motherboard.

Installing the motherboard to the chassis…

If themotherboard 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 of the spacers (the spacer may be a little hard to cut off, so be careful of your 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 circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

Introduction

Special Features — Over Voltage (RIMM/AGP/CPU)

— Over Clock (CPU/PCI/AGP)

M Please set the CPU host frequency in 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, chipset and most of the peripherals. Whetheryour system can run under these specific bus frequencies properly will depend on your hardware configurations, including CPU,Chipsets,SDRAM,Cards… .etc.

1.Pull up the CPU socket level and up to 90-degree angle.

3.Press down the CPU socketlever and finish CPU installation.

2.Locate Pin 1 in the socket and look for a (golden) cut edge on the CPU upper corner. Then insert the CPU into the socket.

MPlease use Intel approved cooling fan.

MWe recommend you to apply the thermal tape to provide better heat conduction between your CPU and heatsink.

(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.)

MMake sure the CPU fan power cable is plugged in to the CPU fan connector, this completes the installation.

MPlease refer to CPU heat sink user’s manual for more detail installation procedure.

Step 2: Install memory modules

The motherboard has 4 Rambus In-line Memory Module (RIMM) sockets. The BIOS will automatically detect memory type and size. To install the memory module, just push it vertically into the RIMM Slot .The RIMM module can only fit in one direction due to the two notches. Please note; Both RIMM modules inserted on RIMM1 and RIMM2 slots are recommended to have the same size, frequency . If not, the larger sized module will l be automatically re-sized by BIOS to match the smaller sized module. The same rule applies to both RIMM3 and RIMM4 slots.

You can insert two RIMMs or four RIMMs into RIMM slots, but C-RIMM (Continuity RIMM) modules must be inserted into the empty slots.

RIMM

CRIMM

Check RIMM module if it is supported by the

M/B.

Insert the RIMM module into the slot.

Push the ejector tab towards the RIMM.

M When STR/RIMM LED is ON, you do not install / remove RDRAM from socket.

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 whitedrawable bar at the end of the AGP slot when

you try to install/ Uninstall the AGP card. AGP Card Please align the AGP card to the onboard

AGP slot and press firmly down on the slot . Make sure your AGP card is locked by the small whitedrawable bar.
