Setup Tips
Update BIOS Before Installing CPU
Use USB BIOS Flashback to update the BIOS even without a CPU. Download the latest BIOS from ASUS, rename it, place it on a FAT32 USB drive, insert it into the marked port, and press the Flashback button. This ensures compatibility with the latest 14th Gen CPUs.
Enable XMP/EXPO for Full DDR5 Speed
Enter the BIOS (press Del during boot), switch to EZ Mode, and enable XMP 3.0 or EXPO to run your memory at its rated speed. Without this, DDR5 defaults to 4800 MHz, leaving performance on the table.
Install M.2 SSDs with Q‑Latch
The M.2 slots use a tool‑less Q‑Latch mechanism. Simply rotate the plastic latch, insert the drive, and rotate it back to lock. No tiny screws required. Use the bundled thermal pad on the primary slot for maximum cooling.
Optimise Fan Curves with AI Cooling II
In Armoury Crate, activate AI Cooling II. It will automatically adjust fan speeds after analysing your system’s thermal response. You can still manually tweak individual fans if desired.
Connect Thunderbolt 4 Correctly
The Thunderbolt 4 port on the rear I/O is also a USB4 port. For video output, you may need a DisplayPort cable from your GPU to the DP IN connector on the motherboard (if present) or rely on CPU integrated graphics.
