The F2A85XN-WIFI features the now standard Gigabyte UEFI DualBIOS with a graphical user interface and mouse support. It offers all the functionality you would expect from a modern motherboard though some of the settings are scattered in different sub-menus.

Advanced Frequency Settings.

BIOS/UEFI Summary: Gigabyte GA-F2A85XN-WIFI
BCLK/PCIe Clock Control 100 to 140 MHz
GPU Clock 300 to 2000 MHz
CPU Voltage 0.800 to 1.800 V
CPU Voltage (Dynamic) -0.800 to +0.350 V
NB Voltage 0.800 to 1.800 V
NB Voltage (Dynamic) -0.800 to +0.350 V
Memory Frequency 800 MHz to 2400 MHz
Memory Timing Options Intermediate
DRAM Voltage 1.200 to 1.900 V

Glancing at the options in the BIOS/UEFI, it's clear that this isn't a hardcore enthusiasts' board. The degree of frequency and voltage adjustment is enough for most overclockers but there are no ridiculous high limits aside from the GPU clock. It does have a couple of nice touches that I like to see, the ability to undervolt, and dynamic voltages adjustments which apply both when the APU is idling, on full load, and anywhere in-between.

AI Tweaker menu.

Mini-ITX systems typically don't have many fans, so the F2A85XN-WIFI is only equipped with a pair of PWM fan headers. Basic control is available in the BIOS/UEFI. Users can use the predefined "Normal" and "Silent" settings or choose "Manual" to adjust how quickly the fans react with a bit more refinement. After some trial and error, I found that "Normal" was the equivalent of the 1.75 setting while "Silent" corresponded to 1.00.

Boot Performance

To test boot time I optimized the BIOS menu by setting the hard drive 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 (I stop here because this is the point where the O/S drive speed becomes a factor).

The boot process on the F2A85XN-WIFI is about average for an FM2 board, hitting the Windows loading screen in under 12 seconds. It's not particularly quick, but for some users, it will reach this point before the monitor even comes out of standby mode.
