Innovative ASUS features

ASUS UEFI BIOS

Flexible and Easy BIOS Interface

ASUS UEFI BIOS offers the first mouse-controlled graphical BIOS

designed with selectable modes, providing a user-friendly interface

that goes beyond the traditional keyboard-only controls. It also natively

supports fully-utilized hard drives larger than 2.2TB in 64-bit operating

systems.

ASUS exclusive interface

EZ Mode displays frequently-accessed info. Users can choose system

performance settings, and drag and drop boot priorities. Advanced Mode

for performance enthusiasts includes detailed DRAM settings via a

dedicated memory info page for complete insight.

New upgrade! Quick and easy information for enhanced system

control

-

F12 BIOS snapshot hotkey for sharing UEFI information and

troubleshooting

-

New F3 Shortcut for most accessed information

-

ASUS DRAM SPD (Serial Presence Detect) information for accessing

memory information, detecting faulty DIMMs, and helping with difficult

POST situations.

DIGI+ VRM - Digital Power Design

All-new digital CPU power controls work perfectly together to match

digital power signal (SVID) requests from the CPU, with ultra-fast sensing

and response efficiently delivering precision power. Accurate delivery

reduces waste, and provides more stable CPU Vcore voltages. Users

can adjust CPU PWM voltages and frequencies for various overclocking

scenarios, with accurate input through UEFI BIOS tuning or the exclusive

ASUS interface. This proprietary design increases overclocking

headroom to push performance to its full potential.

USB 3.0 Boost

With USB 3.0 Boost technology, a USB device’s transmission speed is

significantly increased, adding to an already impressive fast USB 3.0

transfer speed. ASUS software automatically accelerates data speeds for

compatible USB 3.0 peripherals without the need for any user interaction.

GPU Boost

Go to the Limit with iGPU Level Up!

GPU Boost accelerates the integrated GPU for extreme graphics

performance. The user-friendly interface facilitates flexible frequency

adjustments. It easily delivers stable system-level upgrades for every use.
