BIOS Functionality

In our previous reviews of Asus products we have already talked about Asus EFI BIOS – an overall very successful implementation of the UEFI standard (Unified Extensible Firmware Interface). Therefore today we are going to briefly refresh your memory of the major BIOS sections and their parameters and settings.

By default, there is “EZ Mode” enabled in the BIOS. It performs mostly informational functions, because there are barely any configurable parameters there. You can check the basic system settings, some monitoring data, select an energy-efficient or performance mode and set the order of boot-up devices by simply dragging and dropping them with the mouse pointer.

You can quickly switch from “EZ Mode” to “Advanced Mode” by pressing F7, or use the F3 hot key to jump over to one of the most frequently used BIOS sections.

You can switch from “EZ Mode” to “Advanced Mode” every time you enter the BIOS, or press F3 key which also works if pressed while in any other BIOS section, yet it could be much more convenient if you made “Advanced Mode” a default setting. In this case the first section you see will be the familiar “Main” section, where you can receive some basic system information, change the interface language and set up date and time.

Most of the overclocking-related options are traditionally gathered in the “Ai Tweaker” section. The main section window allows you to change the frequencies, multipliers and voltages. You don’t need to go over to the “Monitoring” section to check the current voltages, as they are all listed right here next to each of the parameters used for changing these voltages, which is highly convenient. The voltages may be set above or below their nominal values.

As usual, some parameters are singled out into individual sub-sections in order to unload the main section a little bit. “OC Tuner” parameter only looks like a sub-section, but in reality it helps to automatically overclock the system. The memory timings can be configured on an individual page. They are indeed very numerous, but still very easy to work with. You can see all timings that the mainboard sets for each of the two memory channels. And you can adjust only a few selected timings, such as the main ones, for example, leaving all other settings at defaults.

The “CPU Power Management” sub-section allows configuring the parameters affecting “Intel Turbo Boost” technology. However, you do not have to do that, because the board will automatically adjust everything to match your selected overclocking goals.

You can’t help noticing numerous options related to the power and energy-efficiency of the digital DIGI+ voltage regulator. You can configure Asus’ proprietary power-saving technologies that allow changing the number of active phases in the voltage regulator circuitry depending on the CPU utilization right in the BIOS. “CPU Load-Line Calibration” technology that prevents the CPU Vcore from dropping under heavy load may be not only enabled or disabled, but also adjusted to deliver the desired effect.

The functionality of the parameters in the sub-sections of the “Advanced” section is quite clear from their names. There is only one new parameter designated to Thunderbolt port.
