         What is the GIGABYTE Ultra Durable™3 design?
The signature specifications for GIGABYTE Ultra Durable™ 3 motherboards are Japanese Solid Capacitors featuring 50,000 hr. operation time, 2x Copper PCBs, Ferrite core chokes with higher energy efficiency compared to more common iron core chokes and Lower RDS(on) MOSFETs that feature lower resistance, i.e. reduced power consumption and heat.

Benefits of 2x Copper PCB
● Cooler than traditional motherboards
● Enhanced durability
● Improved energy efficiency
● Greater margins for overclocking		 PCB (Printed Circuit Board)
2x copper PCB = 2 oz copper PCB = weight of copper layer
30.48 cm x 30.48 cm (1 square foot) PCB is 56.7 g (2 oz)

                  Driver MOSFET : Integration of VRM Components
 
A traditional Voltage Regulator Module (VRM) consists of a Choke, Capacitors, MOSFETs and a Driver IC. By incorporating the MOSFETs and driver IC in accordance with the Intel® Driver MOSFET specification, we can achieve higher power transfer and increased efficiency at higher switching frequencies to satisfy the growing power requirements of today’s processors. Driver MOSFETs also help to reduce VRM real estate requirements in the CPU zone.
