It supports up to 128 GB DDR4 memory across four DIMM slots, SATA III storage with RAID 0/1/10, and Gigabit Ethernet via Realtek RTL8111H. As part of the ASUS Corporate Stable Model (CSM) program, this board includes long-term lifecycle support and comes with ASUS Control Center Express for centralized IT monitoring and management.

Advantages

It also offers diagnostic and maintenance tools like the ASUS Debug header for faster troubleshooting and the Commercial BIOS Kit for partial BIOS updates.

Suitable for

  • Small and medium business desktops and workstations
  • IT-managed endpoint deployments requiring lifecycle support and remote management
  • Systems needing secure boot, TPM-based protection and BIOS recovery
  • Compact office PCs or single-socket servers based on AMD AM4 processors

How to use
