GA-8IHXP Motherboard
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
othercomponents.
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.
If the motherboard 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.

#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. Whether your system can run under these specific bus frequencies properly will depend
on your hardware configurations, including CPU,Chipsets,SDRAM,Cards….etc.

board.
2. Make sure the CPU fan is plugged
to the CPU fan connector, than
install complete.
##
##
#Please use Intel approved cooling fan.
##
##
#We 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.)
##
##
#Make sure the CPU fan power cable is plugged in to the CPU fan connector,
this completes the installation.
##
##
#Please refer to CPU heat sink user’s manual for more detail installation
procedure.

Hardware Installation Process
Step 2: Install memory modules
The motherboard has 4 Rambus In-line Memory Module (RIMM) sockets. The BIOS will automati-
cally 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.
Push the ejector tab towards the RIMM.
#When STR/RIMM LED is ON, you do not install / remove RDRAM from socket.
RIMM CRIMM
Check RIMM module if it is supported by the
M/B.
Insert the RIMM module into the slot.

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.
AGP Card
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 .
Make sure your AGP card is locked by the
small white- drawable bar.
Issues To Beware Of When Installing CNR
Please use standard CNR card like the one in order to avoid mechanical problem.
