Board Software
Gigabyte has a somewhat universal access hub for all of its programs. After downloading the program, you can install system drivers and Gigabyte's supporting software. My only complaint is when viewing the available software—Norton Internet Security is already checked off and will install if you aren't looking for it. Having Gigabyte-created software listed as suggested or "necessary" for download is fine, but auto-checked anti-virus or internet security software crosses into bloatware territory.
Gigabyte Easy Tune is the software for controlling CPU overclocking and voltage settings inside Windows. It is similar to Intel Extreme Tuning Utility, but designed solely for Gigabyte motherboards.
Gigabyte System Information Viewer is mainly for fan control. Though, you can look up system information in this program as well. It is a bit confusing to users to know that this program is for system fan control and not a program named "Fan Controller" or something more relatable.
Gigabyte RGB Fusion 2.0 should be installed if one wants control over the RGB lighting. There are open-source alternatives, but those are not Gigabyte-branded and may not work as intended.
