| Lower Temperature |
Doubling the amount of copper provides a more effective thermal cooling solution by delivering more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. In fact, GIGABYTE Ultra Durable™ 3 series motherboards are able to deliver twice as cool working temperatures than traditional motherboards.
Configurations:
CPU : AMD Phenom X4 9950; Memory : DDR2 800 512MB *2;
VGA : Integrated UMA chipset

2X Lower Impedance |
In addition, doubling the amount of copper lowers the PCB impedance by 50%. Impedance is a measure of how much the circuit impedes the flow of current. The less the flow of current is impeded, the less amount of energy is wasted. For GIGABYTE Ultra Durable™ 3 series motherboards, this means total PCB electrical waste is reduced by 50%, which also means less heat is generated. 2 ounces of copper also provides improved signal quality for better system stability and allowing greater margins for overclocking. |

Better Overclocking |
DDR3 1800+ / DDR2 1333+ Support
The World's Fastest DDR3 / DDR2 Motherboard |
| |
Delivering native support for DDR3 up to 1800+ MHz / DDR2 up to 1333 MHz, GIGABYTE Ultra Durable™ 3 series motherboards allow users to reach higher memory frequencies at lower voltages; achieving higher memory performance with lower power consumption to run even the most memory intensive applications such as high-definition video and 3D games with ease. |

Lower EMI |
|
A good PCB circuit layout is the key to controlling EMI emissions. GIGABYTE Ultra Durable™ 3 series motherboards feature 2 ounces of copper for the ground layers, improving signal integrity and lowering EMI emissions through a very effective ground plane.
* Electromagnetic interference (or EMI) is unwanted disturbance
signals that affect surrounding electronic devices. |
Lower is better |

 |
Better Power Efficiency |
Increasing the thickness of the motherboard PCB Power layer by using 2 ounces of copper allows the electric current to flow with less resistance, enabling more power efficient circuits with lower power loss and less heat generated. |
|
| |
| |
Better ESD Protection |
2 ounces of copper for the Ground layer of the motherboard PCB allows for a more efficient Electro-Static Discharge (ESD) of up to 10%. This helps to better protect the motherboard components against damage caused by static electricity. |
