Enhanced Memory & Storage Performance

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that empowers users to achieve unparalleled memory performance with cutting-edge CUDIMM memory. Through a two-phase comprehensive tuning process, AEMP III first optimizes the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at cutting-edge speeds of DDR5-7600 or higher.2

DIMM Fit / DIMM Fit Pro

DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyzes individual memory modules to optimize performance and pinpoint potential issues. DIMM Fit Pro gives advanced PC builders more extensive customizability for memory tuning. It allows users to control up to twenty overclocking parameters, define testing ranges, and prioritize stability or performance, offering a more flexible and granular approach to memory optimization.

VRM heatsinks and thermal pads

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

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.

​​​​​4-Pin PWM/DC fan

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

M.2 heatsink

One M.2 heatsink takes care of the M.2 slot, 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.

Cooling

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
