Intel®  G41 Chipset
GIGABYTE Ultra Durable 3 series motherboards once again lead the motherboard industry for the highest quality and most innovative motherboard design. Featuring the industry’s first consumer desktop motherboard design to introduce 2 ounces of copper for both the Power and Ground layers, delivering a dramatically lower system temperature, improved energy efficiency and enhanced stability for overclocking. GIGABYTE Ultra Durable 3 Classic motherboards are equipped with the GIGABYTE Ultra Durable signature features including Japanese Solid Capacitors boasting an operational life time of more than 50,000 hours, Lower RDS(on) MOSFETs (providing lower resistance to reduce power consumption and heat generation) and GIGABYTE patented DualBIOS™ technology (providing dual hardware BIOS protection). GIGABYTE Ultra Durable 3 Classic motherboards promise to 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.
