BIOS/UEFI

The Z87N-WIFI features a revamped BIOS/UEFI interface with graphical improvements and mouse support. This overhaul has been long overdue and brings them into the same league as ASUS and MSI.


Most of the features of the old interface are available but they're presented in a more visual style with sliders and a cosmos background to make the experience feel more ominous.



Pressing "F2" switches to Classic mode, bringing you back to the old school interface.

With many advanced options available in the BIOS/UEFI, it's clear that this is an hardcore enthusiasts' board. The degree of frequency and voltage adjustment is more than enough for most overclockers. For those looking to limit their environmental footprint, undervolting with offset options are offered as well.

The built-in fan controls are relatively simple. Both of the board's fan headers are controllable with three different presets. Manual control gives you eight options for the slope of the speed to temperature reaction.

Boot Performance

To test boot time the BIOS/UEFI was optimized by setting the hard drive recognition and other delays set to minimum, taking care not to disable common functionality like USB support, POST messages, etc. and measured the time it takes to reach the Windows loading screen (we stop here because this is the point where the O/S, CPU, and drive become factors).

The boot process on the Z87N-WIFI is about average compared to the last few boards we've reviewed, hitting the Windows loading screen in 12.5 seconds. It's not particularly quick, but for some users, it may reach this point before the monitor even comes out of standby mode.
