This implementation of Gigabyte's 3D Bios is a welcome sight in terms of functionality and ease of use. The GA-Z77X-UD5H-WiFi uses an AMI EFI BIOS that supports PnP 1.0a, DMI 2.0, SM BIOS 2.6, ACPI 2.0a, and Dual BIOS. A pair of 64MB BIOS chips are used to hold the BIOS and back up BIOS for use if a flash goes wrong or is used as a way to increase the amount of OC Profiles that can be saved. This 3D BIOS has two modes: 3D that has an image of a motherboard and preset options along the bottom of the screen that allows adjustment to the parameters of the board including boot order and top line settings without getting too granular. For that you can switch to the Advanced mode. Here you will find six menus to fine tune the operational parameters and include the M.I.T. Menu, System, BIOS Features, Peripherals, Power Management, and Exit menus.
By entering into the Advanced section of the BIOS you get a more detailed look at the settings that make the board tick. M.I.T. is first on the list and is where you find all of the tools necessary to overclock your installed hardware. In this section you are able to check the currently applied values under current status showing the memory and CPU settings. Advanced Frequency settings is where the bclock and multiplier are adjusted as well as where the memory XMP profiles are activated. Advanced memory settings allow for the adjustment of the memory multiplier, timings, and displays the applied voltage for the DIMMs. Digging further into the Channel A and B memory timings is where memory performance can be tuned to deliver the highest memory bandwidth and speed. Advanced voltage settings is where the voltages to be applied are set and adjusted to the values that best suit the clock speeds used on the memory and CPU. 3D Voltage control is where the operating frequencies and current limits can be tuned again for greater overclocking margins or higher efficiency. Health Status shows the component temperatures, voltages and the speed of any installed fans. Under the Miscellaneous tab the PCIe support can be set based on the installed CPU. Legacy Benchmark Enhancement is used to help drive system performance in benchmarks such as 3DMark 01 or Super Pi.
The System tab gives basic system information including the BIOS revision, allows setting of the appropriate system language, time, and date to be set, as well as looking at the ATA port info to view the installed drives and how they are configured.
BIOS Features is where the boot sequence is set up, the boot logo is turned on and off, and the boot priority of the attached drives is setup. The Peripherals tab is where the on-board devices can be enabled or disabled. Power Management is where the resume sequence is applied along with the resume mode for the IGP. Last but not least is the Exit tab that allows the user to save and exit or apply the standard default settings for a starting baseline. Here you can also save and load BIOS profiles.
Entering the Q-Flash utility will allow the end user to either search for a BIOS online or search for a BIOS to install from an installed flash drive. I found this utility worked well allowing an update to the latest BIOS at the time of testing.
We have seen the board, the included utilities, and the latest 3D BIOS, so let's see how well the Z77X-UD5H-WiFi performs and overclocks.
