The Z87X-D3H supports either UEFI or Classic Mode BIOS interfaces. In addition to supplying live sensor info, scrolling function key menu bar and mouse support, the UEFI BIOS has a customizable graphical background with several built-in wallpapers/themes to choose from. Our particular board shipped with BIOS release F3 which we subsequently flashed to the latest F7 available. The Home screen contains some basic information and a few of the more commonly selected performance options such as base clock, CPU and memory ratios, and CPU and memory voltage. Users who want more advanced options and adjustments can delve into the second tab - Performance. System Information is a bit of a misnomer as it mainly contains settings to change the BIOS appearance such as mouse speed, background and mode setup.
The BIOS Features tab conversely offers hardware and operating system settings such as USB and PS2 support, CPU virtualization and Windows 8 features. Peripherals has options for the IGP, audio, PCI-E configuration and Network settings. Finally the Power Management tab has a few controls for various wake-on commands and standby options.
Switching to the Classic Setup on the System Information tab gives us a more traditional BIOS screen layout, although mouse support is enabled and it's more graphically pleasing than plain text-based menus. The first tab up is M.I.T. (Motherboard Intelligent Tweaker) which contains all of the performance altering settings. In Classic mode the System Information displays only the BIOS detail and basic date/time options. BIOS Features contains most of the same settings as it did in the UEFI mode.
The Peripherals and Power Management sections have options nearly identical to their UEFI counterparts, only arranged in a top to bottom format. All of the function shortcut keys are defined in a common area in the lower right corner and access to return to the UEFI dashboard is ever present in the upper right.
Let's continue with testing and overclocking.
