Performance
Digital Power Design
PRIME B850M-A-CSM features an 8+2+1 phase power design with
discrete MOSFETs, ensuring efficient and stable power delivery for AMD
processors plus steady performance for day-to-day use.
The multi-layered printed circuit board design quickly dissipates heat
around the voltage regulators to improve overall system stability and
provide the CPU with more overclocking headroom.
The Digi+ voltage-regulator module (VRM) delivers real-time control over
voltage droop, automatically switching frequency and power-efficiency
settings.
Enhanced Memory & Storage Performance
Enhanced DDR5 performance
Comprehensive memory tuning options are the cornerstone of
PRIME motherboards. The PRIME B850M-A-CSM maximizes the potential of
your DDR5 modules, from entry-level to extreme-speed kits.2
For entry-level modules without EXPO™ support, ASUS Enhanced Memory
Profile (AEMP) automatically detects memory chips and provides optimized
profiles for enhanced performance.
For those looking to surpass stock DDR5 speeds, the PRIME B850M-A-CSM
offers extensive AMD Extended Profiles for Overclocking (EXPO™) support
and a wide array of UEFI settings for further performance tweaks.
Three M.2 slots (up to 128 Gbps)
PRIME B850M-A-CSM offers a total of three M.2 slots, including
one that supports data-transfer speeds of up to 128 Gbps via PCIe 5.0,
and two that support PCIe 4.0. This enables quicker boot-up and app load
times with OS or application drives.
