Board Software
Gigabyte has included a rather standard software package with the Z77X-UD5H WiFi, with a bunch of utilities that are standard to most of their products. EasyTune 6 and @bios are board-level tools for sensor monitoring, clock customization and BIOS updating that are included with most Gigabyte boards, and have been for many years. The overall functionality has not changed much at all here.
New with the International Rectifier VRM is a utility called AutoGreen that allows users to set power profiles to save on power usage, and the Intel Control Center is new-for-Z77 Express software provided by Intel to manage Intel's own tools, such as the iRST panel.
The audio tools were a bit of a surprise, as I was not expecting the Creative SoundBlaster X-Fi MB2 software as it's not mentioned on the box at all, although the THX functionality was indicated by a logo on the box. Both are fairly basic controls, but since there's something to be said about keeping it simple, I rather appreciate the lack of options.
