LatestSecurityDownload from ASUS (opens in new tab)"1.Enhanced system security and added support for HUDIMM. 2.Improved overall system performance and stability. Updating this BIOS will simultaneously update the corresponding Intel ME to version v19.0.5.2175v0.3.The ME version will remain updated even if you roll back to an older BIOS later. We recommend using EZ Flash to update the BIOS, as it supports ZIP format and auto-updates the ME. If using USB BIOS FlashBack, ensure the ME version matches the BIOS version and rename the BIOS file with BIOSRenamer before proceeding. Before running the USB BIOS Flashback tool, please rename the BIOS file (A5555.CAP) using BIOSRenamer."

Why Keep Your Firmware Updated
Motherboard BIOS/UEFI firmware is essential for hardware initialization and CPU compatibility. Updates often include microcode patches for security vulnerabilities, support for newer processors and memory, and stability improvements. Always use a UPS or ensure stable power during BIOS updates — an interrupted flash can render the board unbootable.
