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). By default, you get directly to the “Extreme Tweaker” section when you access the BIOS. This section contains the majority of overclocking and fine-tuning related parameters. 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 the corresponding parameters, which is highly convenient.
As usual, some parameters are singled out into individual sub-sections in order to unload the main section a little bit. Namely, 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 “GPU.DIMM Post” sub-section performs an informational function and shows the settings for the installed graphics cards and memory modules.
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.
I can’t help pointing out a lot of options that deal primarily with the power and energy consumption. They appeared due to the digital “DIGI+” voltage regulator circuitry. 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 Vdroop effect.
Since it is an enthusiast mainboard, it really makes a lot of sense that the first section we see when we access the BIOS is “Extreme Tweaker”, and only then we see the “Main” section – the start-up section for regular mainstream boards. Here you can receive some basic system information, change the interface language and set up the date and time.
The functionality of the parameters in the sub-sections of the “Advanced” section are quite clear from their names.
The “CPU Configuration” sub-section reports the basic info about the processor and allows managing some processor technologies.
All parameters related to power-saving are singled out on a separate page called “CPU Power Management Configuration”.
“Monitor” section tells us the current temperatures, voltages and fan rotation speeds. All of them are separated into individual pages.
“Voltage Monitor” page displays current voltages.
