3.1.2. GIGABYTE Extreme Dual BIOS technology As opposed to the traditional concept of dual BIOS chips where one is a main BIOS and the other one is a backup BIOS, GIGABYTE Extreme Dual BIOS technology contains two different BIOS chips designed for separate purposes. GIGABYTE Extreme Dual BIOS technology supports one-touch dual BIOS switching button to shift between two BIOSes, SOC (Super Overclock Series) Default BIOS and LN2 BIOS. SOC Default BIOS allows gamers to build their dream machines to conquer digital battles on the web. LN2 BIOS is especially designed for overclockers to avoid potential cold bug issues at extremely low temperatures. This feature equips selective GIGABYTE Super Overclock Series for extreme overclockability to break world records at any competitions. How to use? An Extreme Dual BIOS switch is meant to prevent "cold-bug" boot errors when using extreme cooling techniques such as liquid nitrogen, liquid helium and dry ice, etc. GIGABYTE Extreme Dual BIOS switch is available on certain GIGABYTE Super Overclock series graphics cards. SOC Default BIOS. The factory default BIOS setting for Extreme-Dual-BIOS-ready SOC graphics card is SOC Default when graphics card hits the shelf (indicated by blue LED light, switch button pressed down). LN2 BIOS. For attempts of extreme overclocking, press button to switch from default BIOS to the alternative LN2 BIOS (indicated by red LED light, switch button up). Reboot system to apply new BIOS settings. *The "cold bug" is an issue occurred when a processor ceases functioning or overclocking at a low (usually sub zero) temperature, preventing the use of extreme cooling methods such as dry ice or liquid nitrogen. Warning: Before start of extreme benching with LN2 BIOS, make sure extreme overclocking cooling accessories are ready. Troubleshooting If LN2 BIOS is damaged during extreme benching, press switch button again go back to factory default BIOS before rebooting system. SOC Default BIOS will serve as backup BIOS. *For system safety and stability, using SOC Default BIOS setting is highly recommended. - 15 - Software Installation
