BIOS Functionality

In our previous reviews of Gigabyte mainboards on Intel Z77 Express chipset we pointed out a number of changes compared with the first version of Gigabyte 3D BIOS. The new revision of Gigabyte 3D BIOS not only looks different, but has undergone significant modifications in the feature aspect as well.

At this point Gigabyte has successfully fixed and eliminated minor issues in the 3D Mode, the available settings and their adjustment intervals are identical for both mainboards. Therefore we are going to discuss the features and functionality of the current Gigabyte BIOS version using the “Advanced Mode” of the Gigabyte GA-Z77X-UP5 TH mainboard as an example.

When you switch to the “Advanced” mode, you get into the “M.I.T.” (MB Intelligent Tweaker) section, which contains all parameters related to overclocking and performance optimizations. The section main screen only lists all sub-sections and reports the basic system data.

Then we see a purely informational “M.I.T. Current Status” sub-section telling you the current operational parameters of the system.

The “Advanced Frequency Settings” sub-section allows you to adjust frequencies and multipliers and there are special informational parameters that will keep you posted about the changes you are making.

The settings dealing with processor technologies, detailed adjustment of the CPU clock frequency multiplier and power-saving modes are singled out onto a separate page called “Advanced CPU Core Features”.

“Advanced Memory Settings” sub-section allows you to fine-tune the memory sub-system.

Parameters controlling numerous memory timings are all on separate pages. You can set the timings simultaneously for both memory channels or individually for each one of them.

“Advanced Voltage Settings” sub-section allows you to work with different voltages that are all grouped into three separate pages.

There are a few new parameters in the “3D Power Control” page, which appeared due to the introduction of “3D Power” technology. Now you can set the operational mode for the processor voltage regulator, adjust the level of Vdroop counteraction under heavy load and change a lot of other options right in the BIOS.

The voltages in different parts of the processor can be changed on “CPU Core Voltage Control” page. The CPU Vcore may be locked at a certain value or you may also add a certain value to the nominal setting.

The voltages may be not only increased, but also reduced below the nominal, which may come in very handy sometimes. For example, you may need it if your CPU is functioning at the lower than nominal frequencies or if you are using low-voltage memory modules.
