Performance

Digital Power design

The PRIME B840M-A-CSM features a 8+2+1 phase power supply design with discrete MOSFETs to ensure efficient and stable power supply for AMD processors and consistent performance for daily use.5

The multi-layer board design quickly dissipates the heat around the voltage regulators to improve the overall stability of the system and give the CPU more over-clocking room.

The power saving feature contains several settings to optimize power consumption and maximize energy savings. You can activate a CPU power limiter, darken the Aura lighting, and set the fan profile to a power save mode. You can also switch the power-saving plan that is built into Microsoft Windows.

The Digi+ Voltage Regulator Module (VRM) provides real-time control over the voltage drop and automatically controls the frequency and energy efficiency settings.

Improved memory & storage performance

Improved DDR5 power

Comprehensive memory tuning Opti ions are the cornerstone of the PRIME motherboards. The PRIME B840M-A-CSM maximizes the potential of your DDR5 modules, from entry-level to extreme-speed kits.2
For entry-level modules without EXPO™ support, the ASUS Enhanced Memory Profile (AEMP) automatically detects the memory chips and offers optimized profiles for improved performance.
For those who want to exceed standard DDR5 speeds, the PRIME B840M-A-CSM offers extensive AMD extended profiles for overclocking (EXPO™) support and a wide range of UEFI settings for further performance improvements.3


Three M.2 slots (up to 64 Gbps)

The PRIME B840M-A-CSM offers a total of three M.2 slots, two of which support data transfer speeds of up to 64 Gb/s via PCIe 4.0 and a PCIe 3.0. This enables faster boot and load times for operating systems and applications4.

Cooling

Cooler by design

The PRIME B840M-A-CSM motherboard is equipped with several onboard heat sinks and a series of hybrid fan headers to ensure that your system stays cool and stable even under heavy loads.

Intel silent cooling precision


ASUS Fan Xpert 2+

The ASUS Fan Xpert 2+ software offers comprehensive control of the fan. The Auto-Tuning mode intelligently configures all parameters with a single click. There is also an extremely quiet mode, which reduces the fan speeds below the standard minimum, so that your system remains whisper-quiet in light tasks. The fans can also be controlled from the UEFI BIOS.5
