Tom's Hardware reports: "Gigabyte announced this week a new technology which it calls Ultra Durable 3, promises that motherboards featuring the new technology will achieve better overclocking, reduced heat and increased energy efficiency. The premise of the new technology is actually rather simple; increasing the amount of copper used in a motherboard will lower the impedance, reduce heat and improve signal quality.
According to Gigabyte, Ultra Durable 3 motherboards will be the first consumer desktop motherboards to feature 2-ounces of copper for each power and ground layer, doubling that of traditional motherboards. A bit like how a larger copper heat sink often works better than a smaller one, having more copper throughout the motherboard allows for more efficient spreading of heat. As such, heat created by critical components on the motherboard will spread out across the entire motherboard more effectively, which Gigabyte claims can deliver 50°C cooler working conditions than traditional motherboards. Somehow that claim seems to be a bit misleading, but it should be interesting to see in tests how much cooler the motherboard components actually do get."
