• 

  Direction Finder

  Armoury Crate's Direction Finder* helps users detect the optimal antenna orientation for achieving the best WiFi signal strength.

  *The Direction Finder is only compatible with connections in the 5GHz and 6GHz bands

NPU Boost

The integrated NPU in Intel^® Core™ Ultra Processors (Series 2) efficiently accelerates AI workflows — and NPU Boost lets you do more with it. This BIOS feature overclocks the NPU with just one click, increasing performance by up to 24%.

* This feature only supports Intel K series processors
** The overclocking performance may vary depending on the CPU series and motherboard used.
*** Testing was conducted with an Intel Arrow Lake QS Q2HA Ultra 9 285K processor, ROG Maximus Z890 Extreme motherboard, GeForce RTX™ 4090 24GB graphics card, and XPG Lancer DDR5 memory modules (model AX5U6000C4016G).?

M.2 PCIe 5.0 Support

This motherboard also features two PCIe 5.0 M.2 slots to enjoy the fastest data transfers of up to 128 Gbps*, and all M.2 slots support NVMe RAID configurations to take advantage of the latest available speeds.

Power Design

Stable power is crucial for maximizing the performance of AMD processors. The motherboard is designed to meet the needs of high-core-count CPUs. It features 16(80A) + 1(80A) + 2(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80A each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future Intel processors.

MEMORY

Comprehensive memory tuning options are the cornerstone of TUF GAMING motherboards. With the motherboard, you can extract all the potential out of your DDR5 modules*, whether they're from an extreme-speed kit or an entry-level set that would otherwise be locked.

* Memory overclocking may vary between CPU series. Please refer to the spec table for detailed information.

• AEMP III

  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 DDR5-8000 or higher.*

  *Results may vary according to individual system specifications. Currently, only 2-DIMM configurations are supported. Results are based on a test with an Intel Core Ultra 9 285K processor and 2x16GB SK Hynix DDR5-6400 Clocked Unbuffered DIMM RAM, model HMCG78AHBCA326N.?

• DIMM Fit

  DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyzes individual memory modules to optimize performance and pinpoint potential issues. This offers peak efficiency, compatibility, and system stability.
  Whether you are an overclocker seeking ultimate performance, a competitor pursuing the most responsive gameplay, or a content creator prioritizing rock-solid stability, DIMM Fit provides optimizations tailored to your needs and your hardware configuration.

COOLING?

• Enlarged VRM Heatsinks

  The extensive surface area of this heatsink covers the MOSFETs and chokes to improve thermal performance.

• Multiple Temperature Sources

  Each header can dynamically reference five thermal sensors. Fan Xpert 4 allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

• Smart Fan Protection

  A dedicated integrated circuit protects each fan header from excess heat and electrical currents.

• Superb PCH Heatsink

  An expanded surface area for the chipset cooler maximizes system performance and heat dissipation.

EMPOWERING CONNECTION

• 

  PCIe 5.0 for Graphics Card?

  PCIe 5.0 offers twice the data transfer speed of PCIe 4.0, making it robust enough to handle new data-heavy tasks. PCIe 5.0 also brings other benefits, such as electrical changes to improve signal integrity, backward-compatible CEM connectors for add-in cards and backward compatibility with previous versions of the PCIe bus.
