Hi-Fi Audio High-End Audio Capacitors GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers. Audio Noise Guard GIGABYTE motherboards feature an audio noise guard that essentially separates the board’s sensitive analog audio components from potential noise pollution at the PCB level. PERSONALISATION RGB FUSION 2.0 B660 motherboards feature RGB FUSION 2.0 to offer lighting effected options and customized settings with outstanding aesthetics, and able to let enthusiasts building a stylish and unique gaming PC. * Addressable LEDs are available only on select Motherboards, external LED Strips, Addressable LED Strips are not included with Motherboard purchase. EasyTune™ GIGABYTEs EasyTune™ is a simple and easy-to-use interface that allows users to fine-tune their system settings or adjust system and memory clocks and voltages in a Windows environment. With Smart Quick Boost, one click is all it takes to automatically overclock your system, giving an added performance boost when you need it the most. System Information Viewer GIGABYTE System Information Viewer is a central location that gives you access to your current system status. Monitor components such as the clocks and processor, set your preferred fan speed profile, create alerts when temperatures get too high or record your systems behavior; these are the possibilities of the System Information Viewer. ULTRA DURABLE Q-Flash Plus Update the BIOS easily without installing the CPU, memory and graphics card. With GIGABYTE Q-Flash Plus, you don’t need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you’re good to go!
