• 

  Q-ANTENNA

  With Q-Antenna, attaching a WiFi antenna to your PC is now easy and fast. Instead of slowly rotating two fasteners until they finally lock in, they just snap into place. Less hassle, and more consistent performance.?

PCIE 5.0

The Strix Z890-A offers end-to-end PCIe 5.0 support, and the topmost x16 expansion slot is protected with a SafeSlot retention bracket to bear the weight of the latest graphics cards. One onboard M.2 slot is rated for blistering read and write speeds up to 16 GB/s, while the remainder can deliver still-impressive 8 GB/s transfers. And every M.2 slot is covered with substantial heatsinks to dispatch the heat of next-gen drives.

Power Design

• POWER ARCHITECTURE

  The VRM features 16+1+2+2 power stages, each rated to handle up to 90 amps

• ALLOY CHOKES AND DURABLE CAPACITORS?

  Hi-end chokes and durable capacitors are engineered to resist extreme temperatures, enabling performance that exceeds industry standards.

• DUAL PROCOOL II POWER CONNECTORS?

  ProCool II connectors are precision-built to ensure flush contact with PSU power lines. A metal sheath improves heat dissipation and lowers electrical impedance.?

• EIGHT-LAYER PCB?

  A 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.?

MEMORY

DDR5 Strength

ROG has a rich history of delivering top-tier memory performance, and DDR5 is no exception. Enhanced signal routing can push enthusiast-grade kits well beyond the 8 GT/s threshold on the Strix Z890-A, with even greater speeds on the horizon. For experienced users, the UEFI offers a wide range of options to fine-tune and push performance to its limits.

• 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.

• 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 FLEX

  DIMM Flex provides enthusiasts with a powerful new way to overclock their DDR5 memory modules. It employs specialized circuitry that can boost performance or address potential stability issues, depending on temperature readings. When temperatures are nominal, it can use the extra headroom to increase speeds and efficiency. And when temperatures increase, it can adjust memory behavior downward to maintain stability.
