BIOS/UEFI

The F2A85-M Pro features the now standard ASUS EFI BIOS with a graphical user interface and mouse support. It first presents you with a simplified view with a run-down of the clock speeds, etc., but users who want to get your hands dirty will want to enable the advanced menu.

For those who want even more value out of their FM2 system, ASUS provides a nice set of overclocking options. The base APU frequency can be cranked up to 300 MHz and voltage boosted up to 1.9 V. There's also a flexible array of controls for the chipset and memory.

Frankly, we're more excited by the F2A85-M Pro's fan control system than overclocking. The board is equipped with FAN Xpert 2, which allows for independent control of all four PWM fan headers. Each fan can be set to a prescribed setting (Silent, Standard, Turbo) but there's also a manual option where you enter in temperature and fan speed ranges. There are limitations, at least in the BIOS/UEFI, as the three chassis fan controls cannot be run under 60% speed (this might be a precautionary measure to prevent 3-pin fans from turning off if the speed drops to low). In Windows, the FAN Xpert 2 utility provides a more customized experience.
