The Z170X-UD5 POSTs to a standard BIOS screen, with no sign of previous easy menu or mouse-click friendly picture-driven BIOS. This will likely be a welcome sight for all but PC build beginners, as the standard Gigabyte BIOS provides an easy to navigate menu that is familiar to anyone who has seen the inside of a BIOS before.

Gigabyte's M.I.T. section, or Motherboard Intelligent Tweaker, is where to find all the frequency and voltage controls for the CPU and Memory in one place. The entry screen depicts only the most pertinent information, including the BIOS revision, CPU and Memory frequency, CPU temperature and voltage. The M.I.T. current status page gives a little more detail about each of the CPU cores and Memory slots as well as CPU multiplier ratios and Memory timings. These are all informational only; none of the settings can be changed from here. For that we'll need to jump into the next section.

In the Advanced Frequency Settings, there are two very easy to use overclock features for those who don't wish to mess with individual settings or are feeling brave and want to jump right in. The Performance Upgrade allows the user to pick a percentage level overclock for the system, while the CPU Upgrade menu is a little more granular in that a specific target frequency can be selected. Similarly, if the installed memory supports XMP profiles, as we see here, the Profile1 has already been selected, pushing the memory from a base 1600MHz to its rated speed of 2666MHz. There are even more detailed settings for both CPU and Memory, as we'll explore in the next sections.

In the Advanced CPU Core Settings, the individual clock ratios as well as Turbo clocks and power settings can be adjusted for each CPU core. Similarly, in the Advanced Memory Settings, specific memory speed and timing values can be set, including timing values per channel bank.

Under Advanced Voltage Settings, more options are available for changing CPU and Memory voltages. The PC Health Status section displays current voltages, temperatures and fan speeds, as well as allowing the user to customize values for each fan header to reduce noise or increase cooling, and set limits to shut down the system if a fan fails or a temperature threshold is reached.

Moving on from the M.I.T. section, System Information is a more basic informational display page that shows the current system BIOS revision and date, language and date/time. BIOS Features allows the user to select the boot order, as well as various boot options. The Peripherals page most notably allows the user to select the SATA Configuration mode, whether to run in AHCI, RAID or Legacy.

Wrapping up, the Chipset, Power Management and Save and Exit pages round out the remaining sections of the BIOS. While not detailed as a separate page, it's also worth noting the function keys for Q-Flash (F8) which allows flashing the BIOS from an attached USB drive file, and Print Screen (F12) which allows saving a screen capture to an attached USB drive BMP file.

Next let's go over installation and setup.
