English1-3 Installation of the CPU and Heatsink
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU.  If you install the CPU in the wrong
direction, the CPU will not insert properly.  If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of heat sink paste between the CPU and heatsink.
4. Please make sure the heatsink is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications.  It is not
recommended that the system bus frequency be set beyond hardware specifications since it
does not meet the required standards for the peripherals.  If you wish to set the frequency
beyond the proper specifications, please do so according to your hardware specifications
including the CPU, graphics card, memory, hard drive, etc.

Enabling the functionality of Hyper-Threading Technology for your computer system requires all
of the following platform components:
- CPU: An Intel
® Pentium 4 Processor with HT Technology
- Chipset: An Intel® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled

1-3-2Installation of the Heatsink
The heatsink may adhere to the CPU as a result of hardening of the heatsink paste.To prevent
such an occurrence, it is suggested that either thermal tape rather than heat sink paste be used
for heat dissipation or using extreme care when removing the heatsink.
Fig. 6
Finally, please attach the power connector of the
heatsink to the CPU fan header located on the
motherboard. Fig. 3
Place the heatsink atop the CPU and make sure
the push pins aim to the pin hole on the
motherboard.Pressing down the push pins
diagonally.Fig. 4
Please make sure the Male and Female push pin
are joined closely. (for detailed installation
instructions, please refer to the heatsink installation
section of the user manual)Fig. 5
Please check the back of motherboard after
installing. If the push pin is inserted as the picture,
the installation is complete. Fig.1
Please apply an even layer of heatsink paste on
the surface of the installed CPU.

The motherboard supports DDR II 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.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
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 installed
in only one direction.  If you are unable to insert the module, please switch the direction.

1-4 Installing/Removing Cool-Plus (Northbridge Cooling Fan)
Fig.1
To attach Cool-Plus to
a heatsink, align the
extensions on both
sides with the grooves
in the heatsink as
shown. Firmly press
down until it snaps into
position.Fig.2
Once the fan is prop-
erly affixed onto the
heatsink, plug the
power cable into the
NB_FAN connector.
Fig.3
Before proceeding, first check to make sure that the fans power cable is
disconnected.  Then, while applying pressure to the top of the fan, carefully
use a screwdriver to dislodge the extension on one side.
Exerting too much pressure on the fan during removal might
cause the side extensions to break-off.

Dual Channel Memory Configuration
The GA-G1975X-C supports the Dual Channel Technology. After operating
the Dual Channel Technology, the bandwidth of Memory Bus will add double.
GA-G1975X-C includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR II 1, DDR II 2
Channel B : DDR II 3, DDR II 4
If you want to operate the Dual Channel Technology, please note the following explanations due
to the limitation of Intel chipset specifications.
1. Dual Channel mode will not be enabled if only one DDR II memory module is installed.
2. To enable Dual Channel mode with two or four memory modules (it is recommended to use
memory modules of identical brand, size, chips, and speed), you must install them into DIMM
sockets of the same color.
The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side)
2 memory modules
4 memory modules

The DIMM socket has a notch, so the DIMM memory mod-
ule can only fit in one direction. Insert the DIMM memory
module vertically into the DIMM socket. Then push it down.

Close the plastic clip at both edges of the DIMM sockets to
lock the DIMM module.
Reverse the installation steps when you wish to remove
the
DIMM module.

English1-6 Installation of Expansion Cards
You can install your expansion card by following the steps outlined below:
1. Read the related expansion cards instruction document before install the expansion card into the
computer.
2. Remove your computers 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 computers chassis cover.

8. Install related driver from the operating system.
Installing a PCI Express x 16 expansion card:
The PCIE_12V power connector supplies
extra power to the PCIEx 16 slots. Connect
this connector depending on your system
requirements.
To release an installed card, users can
also press the latch on the opposite side
of the drawable bar as the picture to the
left shows. Please carefully pull out the small white-
drawable bar at the end of the PCI Ex-
press x 16 slot when you try to install/
uninstall the VGA card. Please align the
VGA card to the onboard PCI Express x
16 slot and press firmly down on the slot.
Make sure your VGA card is locked by
the small white-drawable bar.

1-7 Configuring a Multi-Graphics Cards System
1-7-1 Configuring a Multi View System
The exact power requirement will depend on your overall system configurations. You need a
power supply that can provide sufficient and stable power to your system and the two
graphics cards. We recommend a power supply that supplies 400W (or above) and 25A (or
above) +12V current.
If you wish to enable the Multi View function, install two or three similar graphics cards into the
PCIE_16_1, PCIE_16_2, PCIE_4_1, PCIE_4_2 slots
(Note). (It is recommended to use graphics cards of
identical brand and chips. For example: GIGABYTE GV-RX13P256DE-RH).
If you want to set up a single or dual graphics card system, we recommend installing the graphics
card(s) on the PCIE_16 slot(s) to ensure better display performance.
(Note) In order to enable the Dual Graphic function correctly, you have to install at least one graphics
card into the PCIE_16 slot.

1-7-2 Configuring an ATi CrossFireTM System
To enable CrossFireTM technology on the motherboard, you need one ATI CrossFireTM Edition graphics
card (master) and one standard CrossFireTM-ready ATI RADEON graphics card (slave).
Before you begin--
I. Power Requirements:
Before installation, assure that the power supply you use is able to provide sufficient power to fully
support an CrossFire configuration and other components in your system. We recommend a power
supply that provides at least 20A 12V current. Please note that the exact power requirements will
depend on your overall system configurations.
II. Supported Operating Systems:
Only Windows XP operating system is currrently supported by the ATI CrossFire
TM technology.
