Our critically acclaimed UEFI and AI Suite tuning utility offer an accessible range of manual tweaking options for experts who want maximum control over their hardware. They’re accompanied by 5-Way Optimization, a highly configurable auto-tuner that finds the optimal overclock for your build by methodically increasing the frequency and testing stability like a seasoned veteran would.

UEFI BIOS

The renowned ROG UEFI (BIOS) provides everything you need to configure, tweak, and tune your rig. It offers intelligently simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned veterans.

Performance Level Up

The dashboard-style control panel of AI Suite 3 lets you fine-tune almost every aspect of your ROG Zenith II Extreme Alpha system with ease. Get the best balance between performance, cooling, stability, and efficiency via one simple and intuitive interface.

Accurate Voltage Monitoring

Conventional motherboards use single-ended sensing tapped from a location that isn't ideal, leading to a large disparity between the actual voltage fed to the CPU and the value reported to software. Zenith II Extreme Alpha features a differential-sensing circuit that simplifies overclocking and tuning by allowing you to track voltages more accurately.

Accurate Voltage Monitoring

Storage

ROG Zenith II Extreme Alpha supports up to five M.2 drives for maxed-out storage. Two ride the ROG DIMM.2 module, next to the memory slots, and support drives up to 110m. There are another two slots under the aluminum heatsink cover, with a fifth one at the rear of the board. Every one of these slots is wired to support full PCIe 4.0 bandwidth, so they’re compatible with the very latest NVMe SSDs – laying the foundation for the ultrafast transfer speeds needed to support machine-learning algorithms and drive higher-resolution game textures.

Storage

AMD StoreMI

AMD StoreMI is a software utility that accelerates any drive for better system responsiveness with reduced startup and software load times. It combines SSD performance with the affordability and capacity of an HDD by automatically moving frequently accessed data to dedicated SSD storage.

The TRX40 platform is aimed at the most discerning content creators, so Zenith II Extreme Alpha implements the latest USB standards. Ready-to-use ports are located on the rear I/O panel, and there are front-panel connectors on the motherboard to let you put USB right where you need it.
