1-3 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.

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. 5
Please check the back of motherboard after installing. If the push pin is inserted as the picture, the installation is complete.
Fig. 2
(Turning the push pin along the direction of arrow is to remove the heatsink, on the contrary, is to install.) Please note the direction of arrow sign on the male push pin doesn't face inwards before installation. (This instruction is only for Intel boxed fan)
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. 6
Finally, please attach the power connector of the heatsink to the CPU fan header located on the motherboard.
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.

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 properly affixed onto the heatsink, plug the power cable into the NB_FAN connector.
Fig.3
Before proceeding, first check to make sure that the fan's 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.
1-5 Installation of Memory
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.
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.

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)

1-7 Configuring a Multi-Graphics Cards System
1-7-1 Configuring a Multi View System
This function is supported only on Windows XP operating system.
With Multi View technology from GIGABYTE, Dual Graphic enabled motherboards offer multiple display support on up to eight separate monitors. This improves the capabilities and productivity of the user by allowing them to spread multiple windows over eight monitors and view them simultaneously.
Multiple display support for increasing productivity
Multiple display support for immersive video
Before you begin--
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 CrossFireTM technology.
Enabling CrossFire Mode--
Connecting Two Graphics Cards:
Step 1: Observe the steps in "1-5 Installation of Expansion Cards" on page 17 and install the master graphics card (ATI CrossFire Edition) in the PCIE_16_1 slot and the slave graphics card (ATI standard CrossFire-ready) in the PCIE_16_2 slot.
Step 2: Attach the CrossFire cable (included with the CrossFire Edition graphics card) to the DMS connector of the master card and to the DVI connector of the slave card.
DMS Connector
(Master Card)
DVI-I Connector (Slave card)
Step 3: Connect your LCD monitor to the CrossFire cable or connect your VGA monitor via an adapter.
Graphics Card Driver Setting:
After installing graphics card driver in operating system, access the ATI CATALYST Control Center. From the ATI CATALYST Control Center, enter the CrossFire menu and assure to select the Enable CrossFire checkbox to complete the configuration.

1/2) ATX_12V_2X4 / 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 (2x4) power connector mainly supplies power to the CPU. If the ATX 12V (2x4) power connector is not connected, the system will not start. If you wish to install a power supply that provides ATX 12V (2x2) power connector, please connect the ATX 12V power connector to the Pin 3, 4, 7, 8 of the onboard ATX_12V_2X4 power connector according to the pin definitions. Important Use of a power supply providing an ATX 12V (2x4) power connector is recommended by processor manufacturer when using Intel Pentium D Extreme Edition processor.
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 (400W 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. If you use a power supply that provides a 24-pin ATX or 2x4 pin ATX 12V power connector, please remove the small cover on the power connector on the motherboard before plugging in the power cord ; otherwise, please do not remove it.
