GA-Z170X-UD3 Ultra
Anti-sulfur product: An alloy layer has been added to protect the silver layer and prevents the sulfurization reaction from taking place.
GA-Z170X-UD3 Ultra
Without the anti-sulfur layer: The electrode terminals lack a protective layer, which means that oxygen or other environmental elements can penetrate the Ni (Nickel) layer causing a sulfurization reaction and degrade the ability for the electrode to conduct electricity properly.

Anti-Sulfur Resistor Design
Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design AORUS gives Ultra Durable Motherboards a whole new meaning.
