Enhanced Memory & Storage Performance

Enhanced DDR5 performance

Comprehensive memory tuning options are the cornerstone of ASUS B850 motherboards. The B850 MAX GAMING WIFI-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 B850 MAX GAMING WIFI-CSM offers extensive AMD Extended Profiles for Overclocking (EXPO™) support and a wide array of UEFI settings for further performance tweaks.3

Cooling

Cooler by design

The B850 MAX GAMING WIFI-CSM motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.
B850 MAX GAMING WIFI-CSM front view.

VRM heatsinks and thermal pads

Two massive VRM heatsinks and essential thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.

4-Pin PWM/DC fan

Each onboard header supports auto-detection of PWM or DC fans.

AIO Pump header

A dedicated PWM/DC header supports self-contained water-cooling setups.

Multiple temperature sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ lets you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

Flexible M.2 heatsink

The Flexible M.2 heatsink takes care of either of the two M.2 slots, preventing throttling that can occur with M.2 storage during extended transfers.

Passive chipset heatsink

An aluminum passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the buildup of dust and debris.

Smart protection

A dedicated integrated circuit protects each fan header from overheating and excess current.

Smart Cooling precision

ASUS Fan Xpert 2+

ASUS Fan Xpert 2+ software provides comprehensive control over fans. An Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.5
