We’ve already talked about ASUS EFI BIOS in our reviews of the ASUS P8P67 Pro and Sabertooth P67 mainboards and found it to be a very good implementation of the UEFI standard (Unified Extensible Firmware Interface). The ASUS P8P67 Deluxe doesn’t differ much in this respect, but offers a new and most convenient option for capturing screenshots. By pressing F12 you can save a BMP file with a screenshot of the current BIOS page to a connected drive. Therefore I can show you the true look of ASUS EFI BIOS without any distortions peculiar to photographs.
By default the BIOS opens up in EZ Mode which gives you a lot of information but offers almost no user-defined options. You can only choose one of three power-saving modes and define the boot device order by dragging the icons with your mouse.
You can make the BIOS open in Advanced Mode. In this case you will see the familiar Main section.
Most of the overclocking-related options are collected in the Ai Tweaker section. The new BIOS interface may seem unusual but its structure and setup options are quite recognizable as those of ASUS's older BIOS. There are a lot of new options, though, which are mostly related to power supply and the new digital power system called DIGI+.
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.
CPU power supply options occupy a dedicated page, too. By the way, it is only mainboards from ASUS and Gigabyte that can automatically adjust to the user-defined settings and increase the allowable CPU power consumption range. This range has to be adjusted manually on other mainboards.
The options of the Advanced section should be familiar to you and their names are self-descriptive. I can only note that SATA disks work in AHCI mode on ASUS mainboards by default.
The CPU Configuration subsection reports you basic information about the CPU and allows to control some CPU-related technologies.
The Monitor section is where you can check out the current temperatures, voltages and fan speeds. You can select the speed regulation mode for the system fans: Standard, Silent or Turbo. The CPU fan can also be regulated manually.
