Gigabyte X870 Aorus Stealth Motherboard Review: The gothy Goldilocks of rear-connect AM5 motherboards

Firmware

Gigabyte’s updated “UC BIOS 2.0” starts in Easy Mode, is laid out logically, and displays a wealth of information about the system, including processor, RAM, fan speeds, and several selectable options, such as XMP profiles, RAM tweaks, Re-Size BAR support, Smart Fan 6 access, and more. The Aorus Stealth uses a black background with light blue accents and white writing providing a high-contrast screen that’s easy to read.

All headings are still displayed across the top in advanced mode; they are now larger ‘buttons’ and can be easily selected with a mouse. The highlight bar (where you are on the page) is a light blue here and easy to see. Every option you need and want is at your fingertips, and you don’t have to drill down several layers to reach the most commonly used functions – especially if you populate your selections in the Favorites section.

Another feature is that the new 64MB BIOS includes a “DriverBIOS” function that preinstalls your Wi-Fi driver, so you can get online easily when you first boot. It’s a beneficial feature for Windows 11 25H2 users who need an internet connection to use their Microsoft account to install the OS.

Software

Gigabyte Control Center (GCC) is a one-stop solution for controlling various functions, including RGB and Fan control, hardware monitoring, and overclocking. It’s also helpful in finding, downloading, and installing driver updates for your system. It’s a simple application that does its job. It’s also a much cleaner tool than the previous App Center. It earns our approval for the breadth of functionality it offers users. This is the latest version from early 2026.
