We’ve already seen ASUS EFI BIOS, a very successful implementation of the UEFI standard (Unified Extensible Firmware Interface), in our previous reviews of ASUS mainboards. The new BIOS interface may seem unusual but its structure and setup options are quite recognizable as those of ASUS's older BIOS. The most eye-catching difference is the Republic of Gamers color scheme, but there are also quite a lot of extra options inside. This EFI BIOS opens in Advanced Mode rather than the simplified EZ Mode. Most of the overclocking-related options are collected in the first section called Ai Tweaker.
Some of the setup options are available in individual subsections in order not to clutter the main section. One such subsection contains memory timings, for example.
The new GPU.DIMM Post subsection contains basic graphics card and memory module parameters.
ASUS mainboards can automatically adjust to the user-defined settings and increase the allowable CPU power consumption range.
CPU, memory and chipset power management options can all be found on an individual page.
Next goes the familiar Main section which doesn’t contain anything new.
Most of the pages in the Advanced section are also familiar and have self-descriptive names, but there are some of them which are peculiar to the ROG series. The iROG Configuration subsection helps you monitor the current and total system uptime. The ROG Connect feature can be disabled in the namesake subsection. You can also specify the way the boot-up process is indicated: as text or POST codes. The mainboard having a lot of LEDs (highlighted buttons and ROG badge, multicolor Voltiminder LEDs), it is handy that the BIOS offers the opportunity to turn that illumination off partially or completely (on the LED Control page).
The CPU Configuration subsection reports you basic information about the CPU and allows to control some CPU-related technologies.
The pages of the Monitor section are where you can check out the current temperatures, voltages and fan speeds.
