ASUS AI ADVISOR
Using AI technology to understand natural-language questions or scenario descriptions, ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.

* Availability of ASUS AI Advisor may vary by region.
** AI Advisor functions may vary by platform.

AI NETWORKING II
AI Networking II combines intelligent technologies to continuously optimize network performance, provide trustworthy and seamless connectivity, and unleash the full speed of WiFi 7*.

*Features may vary by model.

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%.

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

Asynchronous Clock
For next-level frequency flexibility, the ROG Strix B860-A features a built-in clock generator that isolates CPU base clock from memory, NPU, D2D and NGU. Drive memory, NPU and others performance to their absolute brink while maintaining the stability of CPU clock domains.
Separate CPU BCLK from other domains for unfettered overclocking.

*NGU stands for Next Generation Uncore.

DDR5 DOMINATION
Enhanced signal routing can push enthusiast-grade kits well beyond the 9 GT/s threshold on the Strix B860-A.

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.

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; whereas DIMM Fit Pro is an advanced option that provides more extensive customizability

M.2 HEATSINKS
Heatsinks cover every slot to help keep onboard NVME SSDs at optimal temperatures for consistent performance and reliability.

VRM HEATSINK ARRAY
Two thick heatsinks covering the power delivery section provide strategic airflow channels for increased heat dissipation while empowering high-performance Intel® Core™ Ultra Processors (Series 2)

CPU FAN HEADERS
A dedicated pair of PWM/DC fan headers provides easy access to CPU coolers.

AIO PUMP FAN HEADER
A dedicated PWM/DC header connects self-contained water-cooling setups.

4-PIN FAN HEADERS
The Strix B860-A features four chassis fan headers, each supporting auto-detection of PWM or DC fans.

WIFI 7
The revolutionary WiFi 7 is faster than standard WiFi 6*, thanks to tech like 160 MHz channels** on the 6GHz band and 4K QAM*. Multi-Link Operation (MLO) provides a more stable WiFi connection and lower latency, unlocking the realms of the unknown in gaming, streaming and industrial IoT.

Intel 2.5Gb Ethernet
Onboard Intel® 2.5Gb Ethernet gives your wired connection a boost, with speeds that are 2.5 times faster than standard Ethernet connections for speedy file transfers, low-latency gaming, and high-res video streaming.

PCIE 5.0
The Strix B860-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.

USB4® (20Gbps) PORT
The Strix B860-A comes loaded with one USB4® (20Gbps) port for speedy data transfers up to 20Gbps.

DOLBY ATMOS
ROG and Dolby® have partnered to bring superior gaming audio quality to users. Dolby Atmos expands on traditional surround sound systems by adding height channels, which enables immersive three-dimensional audio to be perceived from above, below and around the listener.

SupremeFX
ROG SupremeFX is a unique blend of hardware and software technologies that provide superior audio. The Strix B860-A implementation features the ALC1220P codec for high-resolution playback up to 32-bit/192 kHz across all channels. Front-panel output is streamed through the integrated Savitech amplifier that can drive high-fidelity acoustics to a wide variety of speakers and headsets.

UNDENIABLY ROG STRIX
The ROG Strix B860-A features a clean white design that complements any build. Its matching metallic heatsinks enhance the sleek look, while Aura Sync RGB lighting adds customizable effects for a subtle or bold style.

OUTSHINE THE COMPETITION
ROG Strix motherboards feature ASUS Aura technology, enabling full lighting control and a variety of presets for both onboard RGB LEDs and third-party accessories. Effects can be easily synced across compatible ROG graphics cards, monitors, keyboards, and mice to give your setup a unified look.
