Its ESS 9281 QUAD DAC™ with a built-in amplifier and Master Quality Authenticated (MQA) rendering technology treats you to hi-fi-grad audio, while AI noise-canceling technology enhances headset microphones for crystal-clear voice communication. OPTIMIZATION The ROG Crosshair VIII Extreme provides all the tools needed for quickly and easily optimizing any system. Level Up Performance The dashboard-style control panel of AI Suite 3 makes it easy to fine-tune almost every aspect of the ROG Crosshair VIII Extreme. Get the best balance between performance, cooling, stability, and efficiency via one simple and intuitive interface. UEFI BIOS The renowned ROG UEFI (BIOS) provides everything needed to configure, tweak, and tune your rig. It offers intelligently simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned veterans. Accurate Voltage Monitoring Conventional motherboards use single-ended sensing circuits that are susceptible to noise and have to tap voltage rails from a location that isn’t ideal for accurate monitoring. These issues lead to a large disparity between the voltage fed to components and the values reported to software. The ROG Crosshair VIII Extreme features a differential-sensing circuit that rejects noise and takes readings directly from the CPU and the end point of major voltage rails. This simplifies overclocking and tuning by allowing you to track voltages more accurately. PERSONALIZE In addition to extraordinary performance, the ROG Crosshair VIII Extreme provides extensive styling and customization options to let you build a system that truly stands apart. Grow Your Gaming World with Aura Sync Up your game with complementary Aura Syncenhanced aesthetics, featuring preset lighting effects that can be easily synchronized across compatible ROG graphics cards, monitors, mice and keyboards to give your setup a unified look.
