BIOS Functionality

Unlike many other mainboards that started using UEFI, Gigabyte mainboards use the so-called “Hybrid EFI” technology. It implies the use of traditional well-polished BIOS based on AWARD micro-code, where only support of hard disk drives with over 3 TB storage capacity is implemented using EFI technologies. However, we would like to start with the start-up screen anyway, because only Gigabyte mainboards are capable of displaying the actual frequency of your overclocked processor, while all others will display the nominal CPU frequency no matter what mode it is.

Just in case, let me remind you that Gigabyte mainboards allow full access to BIOS functions only if you press Ctrl-F1 key combination in the main BIOS window.

It is very convenient that the first on the list is “MB Intelligent Tweaker (M.I.T.)” section that contains all parameters related to overclocking and system performance fine-tuning. The main section window has a list of available sub-sections and reports the basic system info.

Then comes a purely informational sub-section called “M.I.T. Current Status”, which reports the current system settings.

The “Advanced Frequency Settings” sub-section allows adjusting frequencies and multipliers and a number of informational parameters will keep you updated about the effect from the latest changes you’ve made. Here we see the first differences from the previously reviewed LGA1155 mainboards from Gigabyte: we see an option that allows us to change the frequency of the graphics core built into the processor and an information line that reports its current frequency.

The settings related to processor technologies are all summed up on a separate page called “Advanced CPU Core Features”.

“Advanced Memory Settings” sub-section offers options for configuring the memory sub-system.

The memory timings can be adjusted on individual pages. The timings can be set for each memory channel individually or for both of them simultaneously.

“Advanced Voltage Settings” sub-section allows adjusting the voltages. The processor core voltage can be set at a certain fixed value or we can just add a certain value to the nominal setting. In the latter case even if you overclock by changing the CPU Vcore, the mainboard will keep all Intel power-saving technologies up and running. In idle mode it will lower not only the CPU clock frequency multiplier, but also the core voltage. By the way, the voltages may be not only increased, but also reduced below the nominal, which may be handy in some cases.

“Standard CMOS Features” section is pretty standard, just like the name says:

“Advanced BIOS Features” section allows adjusting the boot-up devices order during start-up and a few other parameters:

The diverse parameters in the “Integrated Peripherals” section allow configuring additional onboard controllers.

“Power Management Setup” contains pretty common options:

“PC Health Status” section reports current voltages, temperatures and fan rotation speeds. Gigabyte mainboards retained the ability to adjust the rotation speed of three-pin fans. They used to do it automatically only, but since not so long ago they started offering manual adjustment option, too.

You can use some functional keys in the main menu of Gigabyte mainboards BIOS to get access to additional options and functions. By pressing F9 you can open system information window:

By pressing F11 you can save one of the eight full BIOS settings profiles. Each profile can have a detailed name, and if the profile already exists, you will be warned. You can load a profile from the menu that pops up after pressing F12. Besides profiles saved manually, the mainboard automatically saves configurations once the POST has been successfully passed. These configurations may also be restored if necessary. You can save and load profiles using not only the built-in memory, but also external storage media.

If you press F8 you will launch Q-Flash Utility for BIOS updating.
