The Zotac A75-ITX WiFi utilizes an American Megatrends APTIO BIOS that is based on, and compliant with, UEFI specifications. The lack of a GUI may turn some users away, but for the most part it shouldn't matter. The Main BIOS tab will show you some basic system information, as well as allow you to change the system date and time. Moving on to a more interesting section of the BIOS brings us to the X-Setting tab. Here is where you SHOULD be able to do some overclocking, and may ACTUALLY be able to do some overclocking with a future BIOS update or an unlocked chip. Switching CPU Performance Boost Control to Enabled will give you controls to adjust the CPU Multiplier. This is something that would be useful if you could actually increase the multiplier on current AMD Llano chips. You can however lower the multiplier if for some reason you want to downclock your chip. Normally I wouldn't have a problem with a motherboard allowing you to do this, but the Zotac A75-ITX WiFi will not allow you to increase the BCLK, effectively making it impossible to overclock your CPU. Not only that, but you are unable to change any bus speeds, so I'm really not sure why there is even an overclocking section included in the BIOS. You can, however, adjust memory timings and voltages. I actually thought it was a bit funny that you could increase the CPU voltage even though you couldn't increase the BCLK or the multiplier. Hopefully Zotac will release a BIOS update that allows us to do a bit more when it comes to overclocking!
Moving on to the Advanced settings, here you'll be able to adjust PCI settings, configure onboard devices, and access power savings features. The Advanced tab is followed by the Chipset tab, which will allow you to adjust your display configuration, as well as memory settings. This tab is then followed by both the Boot and Security sections, which will let you adjust boot options, boot device priorities, and set a BIOS password.
The remaining two sections of the BIOS are the PC-Health section and the Save and Exit section. The PC-Health section will allow you to monitor idle voltages, temperatures, and fan speeds. The Save and Exit section will allow you to save user defaults, load user defaults, load optimized defaults, and of course, save and exit.
Now let's take a quick look at the included programs and then get to the benching!
