ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.

Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B840M-A-CSM maximizes the capabilities of DDR5 modules, from entry-level to extreme speed kits.
For entry-level modules without EXPO™ support, the ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimized profiles for improved performance. For those looking to surpass standard DDR5 speeds, the PRIME B840M-A offers extensive support for AMD Extended Profiles for Overclocking (EXPO™) and a wide range of UEFI settings for further performance enhancements.

The ASUS Fan Xpert 2+ software provides comprehensive control of the fans. An auto-tuning function intelligently adjusts all parameters with a single click. There is also an Extreme Quiet mode that reduces the chassis fan speeds below the default minimum limit, so your system remains quiet during light tasks. The fans can also be controlled via the UEFI BIOS.

The Realtek 2.5 Gb Ethernet reduces CPU load and offers ultra-high TCP and UDP performance for faster and smoother data transfers.

The pre-installed I/O shield protects the ports, simplifies the building process, enhances functionality, and improves aesthetics for PC DIY enthusiasts.
