In our previous reviews of Asus mainboards we already saw EFI BIOS – a pretty successful implementation of the UEFI standard (Unified Extensible Firmware Interface). By default, when we enter the BIOS, we see EZ Mode screen that mostly performs informational functions, because it hardly allow users to adjust anything at all. You can find out basic system specs, check several monitoring parameters, select energy-efficient or performance mode and set the boot-up devices order by dragging and dropping them with a mouse pointer.
You can easily switch from “EZ Mode” to “Advanced Mode”, but it will be more convenient to set it up as a startup mode right away. In this case the first screen we see on entering the BIOS will be the well-familiar “Main”.
Note that you can change the interface language. If you do so, not all parameters will be translated, and the BIOS looks very unusual even funny in any language other than English, but I am sure it will be very helpful for commencing computer users who do not speak English.
Most overclocking-friendly options are gathered in “Ai Tweaker” section. The new Asus EFI BIOS only looks unusual: the well-familiar functionality of the Asus mainboards BIOS is all still there. However, we also notice a lot of new options that mostly relate to power supply and consumption and appeared because of the new digital “DIGI+” voltage regulator circuitry. You can now configure right in the BIOS Asus’ proprietary power-saving technologies, which adjust the number of active voltage regulator phases depending on the current CPU utilization. “CPU Load Line Calibration” technology that counteracts the processor voltage drop under heavy load can be not just enabled or disabled. Now you can even adjust the degree of this counteraction to your liking. You don’t need to go over to the monitoring section to control the current voltages: they are all displayed right here, next to each of the corresponding adjustable settings. Very convenient.
Some parameters are traditionally moved to individual sub-sections to make the main section less busy. Namely, the memory timings configuring is available on separate pages.
We are very well familiar with the functionality of the sub-sections in the “Advanced” section. Besides, their names are quite descriptive. We would only like to point out that since recently all SATA drives on Asus mainboards work in AHCI mode by default.
