GIGABYTE Ultra Durable™ Series Evolution  
Leading Industrial Quality Standards Year by Year
GIGABYTE set the industry standard for best quality motherboard components since the adoption of ROHS manufacturing practices in 2005. In the following year, GIGABYTE announced the Ultra Durable™ motherboard series featuring all-solid capacitors with better power efficiency than old style electrolytic capacitors. In May 2007, GIGABYTE introduced the Ultra Durable™ 2 series of motherboards that boasted top quality
environmentally friendly solid capacitors from Japan, Lower RDS (On)
MOSFETs that run cooler and Ferrite core chokes that help to reduce
the amount of wasted electricity from the power phases that feed
the CPU. In September 2008, GIGABYTE once again leads
the motherboard industry for the highest quality, most
innovative motherboard design with the launch
of their latest Ultra Durable™ 3 technology.

Advantages of 50,000 Hour Japanese Solid Capacitors
GIGABYTE Ultra Durable™ motherboards are equipped with solid capacitors developed by leading Japanese manufacturers. With an average lifespan of 50,000 hours, these solid capacitors provide the stability, reliability and longevity essential to meet the power needs of high-end processors and other components running today's most demanding applications and games.
1 year = 24 hr. x 365 days = 8,760 hr.
5 years = 8,760 hr. x 5 = 43,800 hr.

  * 50,000 hr. of work time is calculated at 85°C temperature.

  What are Solid Capacitors?  
Solid capacitors and electrolytic capacitors both store electricity and discharge it when needed. The difference is that solid capacitors contain a solid organic polymer, while electrolytic capacitors use a liquid electrolyte.
Solid Capacitors  
Separator sheet (electrolyte) impregnated with conductive polymer. Solid capacitors are composed of highly electro-conductive polymer that dramatically improve stability and reliability.

  Why use Solid Capacitors?  
  Electro-conductive polymer used in solid capacitors helps to achieve the following characteristics:  
  Low ESR in High Frequency Area
  High Ripple Current
  Longer Life
  High Temperature Capability
Low ESR in High Frequency Area=Cooler Motherboard
The Lower Equivalent Series Resistance (ESR) means Less power - solid capacitors are able to deliver substantially lower impedance at higher frequencies. Because there is less impedance, solid capacitors are more stable and generate less heat than electrolytic capacitors.
Tolerating High Ripple Current for a More Stable Motherboard
Higher Ripple Current absorbs higher power switching that plays a decisive role in motherboard power phase design. Solid capacitors have better capacity for power switching and thus, contribute significantly to better motherboard stability compared to electrolytic capacitors.
High Temperature Capability - More Reliable Motherboard
The capacitance of solid capacitors stays stable in sharp changing temperatures - Solid capacitors deliver more stable capacitance and are less likely to be affected by temperature changes. As the chart shows, even at extreme temperatures, solid capacitors have relatively stable capacitance, especially when compared to electrolytic capacitors.
Longer Life - More Durable Motherboards
In terms of lifespan, solid capacitors last longer than electrolytic capacitors, especially at lower working temperatures. As the table below shows, at 85ºC, the average lifespan for a Japanese solid capacitor is more than six times greater than electrolytic capacitors. In actual years, the Japanese solid capacitor will last approximately 5 years, while the electrolytic capacitor dies after only one years. Clearly, solid capacitors have a lifetime advantage over electrolytic capacitors.

No More Exploding Capacitors - More Stability for Overclocking
Swelling and leaking capacitors have bothered motherboard users for ages. This dramatically lowers a PC's performance, and may even damage the motherboard to the point where it can no longer operate. As there is no liquid component to solid capacitors, they don't leak or explode. In addition, their ability to tolerate extreme conditions and their overall robustness make them much more suited to extreme operating environments.

Summary of Solid Capacitor Features
Solid caps have a low ESR
A frequency characteristic of impendence shows an ideal curve
Ideal to use as de-coupling capacitor for removing such noise as ripple, spike, digital, static, audio, etc.
Able to handle large ripple current
Ideal for miniaturization, as a smoothing capacitor of switching power supply.
Able to discharge rapidly
Ideal for use as back-up capacitor in a circuit where large current is consumed at high-speed.
The ESR of Solid capacitor is not greatly affected by temperature
The Solid cap can be used for low temperature specification equipment (0ºC or less)
Solid caps enjoy a longer life
You can expect to use Solid caps for 50,000Hrs (5 years) at 85ºC
This is ideal for devices that should last for a long period.

  Quality Components make Quality Motherboards  
Using high quality components on a motherboard is the key factor for having a long lasting, stable and reliable product. This is especially the case for the power circuit design, which features the most critical components of a motherboard.

GIGABYTE has set the industry standard by using All-Solid Capacitors throughout a wide range of products in 2006. In 2007, GIGABYTE set a new standard by using Ferrite Core Chokes and Lower RDS(on) MOSFETs for its latest upcoming products.

Ferrite core chokes have higher energy efficiency compared to the commonly used iron core chokes because they are able to store energy longer and prevent rapid energy loss at high frequency. Lower RDS(on) MOSFETs have a lower resistance, which reduces power consumption and heat generation.

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 Classic motherboards are able to deliver twice as cool working temperatures than traditional motherboards.
