Broaden virtual horizons with the ROG Crosshair VIII Extreme AM4 E-ATX Gaming Motherboard from ASUS. Designed to leverage the raw power of high-end gaming components, the Crosshair VIII gives you robust features suitable for your favorite titles.

Sporting an E-ATX form factor, the Crosshair VIII gives you ample connectivity options with the X570 chipset acting as the foundation for this motherboard. An AMD AM4 socket supports a wide range of Ryzen processors, has four dual-channel DDR4 RAM slots, six SATA connections, three M.2 SSD interfaces, and even includes a DIMM.2 storage card that supports an additional two M.2 storage units. Two PCIe 4.0 x16 and one PCIe 3.0 x1 expansion slot allow you to equip your rig with powerful graphics and utility cards. Thunderbolt 4 connectivity allows you to use resource-demanding peripherals such as external drive arrays, gain up to 40 Gb/s data transfer speeds, and utilize daisy-chain capabilities to streamline your desktop setup. USB 3.2 Gen 2 and Gen 2x2 ports also support a wide range of peripherals from keyboards to mice, as well as video and audio interfaces. Bluetooth 5.2 allows you to use various wireless devices such as controllers and headphones for a true cable-free experience. Connect to your network with Wi-Fi 6E (802.11ax) technology or use dual-RJ45 ports that provide 2.5 and 10 Gigabit Ethernet speeds if you prefer a wired network connection.

Power & Performance

Power Solution

Designed to leverage the power of resource-demanding components, the Crosshair VIII uses 18+2 power stages rated at 90 amps each for the Vcore and two 90-amp power stages for secondary voltage rails. Dual 8-pin ProCool II power connectors, MicroFine Alloy Chokes, and 10K Premium Capacitors work together to stabilize electrical current within the system, prolonging the lifespan of the motherboard and keeping you in the game for longer.

OptiMem III

Run memory kits at lower latency and reduced voltages while operating at higher frequencies with ASUS OptiMem III. You get improved signal integrity and noise mitigation with enhanced memory trace layouts that produce enhanced connectivity between the memory and your CPU.

Dynamic OS Switcher

Create dual setups designed for work and play with the Dynamic OS Switcher functionality. This allows you to create BIOS scenarios depending on your needs. Configure an overclock scenario for resource-heavy tasks and easily switch to a normalized setup for more relaxed situations.



Spread throughout the Crosshair VIII is a series of heatsinks designed to maintain thermal conductivity for components such as your M.2 solid-state drives and I/O ports. VRM heatsink, aluminum I/O cover, extended VRM heatsink, M.2 aluminum covers, and high-conductivity pads assist in providing integrated cooling solutions. Integrated M.2 backplates ensure high performance under heavy loads, and a large chipset heatsink provides a unique style while keeping your motherboard cool.


An array of thermal headers allows you to monitor your system while providing both liquid and cooling capabilities. Multiple temperature sensors are located around the board to take thermal measurements while 4-pin PWM/DC fan headers with ASUS HYDRANODE give you enough power to run your cooling fans with a bundled ROG fan controller. A dedicated water-cooling zone provides connections including Water Pump+, Water In/Out, and Water Flow connections for radiators and complex custom liquid-cooling units.

ROG Fan Controller

You gain six additional fan headers with the included ROG Fan Controller and integrated FanXpert 4 software, allowing you to add standard and ARGB fans to your setup for stylish cooling capabilities.



Whether you prefer a wired or wireless network connection, the Crosshair VIII has you covered with Wi-Fi 6E wireless networking, giving you quick access and enhanced data upload and download speeds. Dual RJ45 wired network ports offer Intel 2.5Gb and Marvell AQtion 10Gb Ethernet protocols, enhancing wired connections. Additionally, an included Wi-Fi antenna offers a magnetic base so you can set it in various places for the best signal possible.


Two Thunderbolt 4 ports are located on the back-panel of the Crosshair VIII, giving you up to 40 Gb/s data transfer speeds, daisy-chain capabilities, and display support up to 4K resolution. USB 3.2 Gen 2 and Gen 2x2 front-panel connectors accommodate a wide variety of devices, with the Gen 2x2 connector giving you up to 20 Gb/s speeds and 60W Power Delivery that can charge your connected devices.


The Crosshair VIII includes three M.2 storage slots integrated into the motherboard, while a DIMM.2 unit gives you two additional M.2 slots. This DIMM.2 expansion card slides into one of the available PCIe x16 slots, allowing you to enhance your ever-growing library of games. Each of these M.2 slots operates on the PCIe 4.0 protocol for optimal performance.


A wide range of audio enhancements are designed to immerse you deeper into your games while optimizing performance. Audio line shielding blocks electromagnetic interference from the rest of the motherboard, while Nichicon capacitors provide high-quality sound. ESS SABRE9018Q2C and ALC 4082 Codec work together to add depth to your audio experience and stabilize frequencies, while the Switching MOSFETS allow impedance-sensing functions to be ported to the front or rear headphone outputs. Additionally, an included ROG Clavis USB digital-to-analog converter provides support for various headphones with a built-in amplifier and high-end rendering technology.


5-Way Optimization & BIOS

Integrated AI Suite 3 allows you to fine-tune your experience using TPU, EPU, Fan Xpert 4, Digital Power Controls, and Turbo App to refine performance. Advanced and EZ Modes give new and seasoned users ample ways to control the performance of their system and change overclocking capabilities with ease.

Differential Sensing

You can track voltages more accurately with integrated differential sensing circuit which reads values and rejects noise by taking readings directly from the CPU and the end point of major voltage rails.


RGB Illumination

A wide range of customization options allow you to add a sense of personality to your system. Aura Sync unifies RGB colorization between your system and connected peripherals, while the LiveDash provides you with a 2-inch OLED panel that displays useful information and customizable graphics.


The Crosshair VIII comes with a wide range of software designed to streamline your programs and applications to enhance your experience across various games and applications. RAMCache III boosts game loading times by caching any storage device so games and programs can launch quicker. Armoury Crate is a suite of programs that enhance user experience by providing a wide range of uses from customizing your BIOS to setting fan speeds, and more. A one-year subscription to AIDA64 Extreme allows you to benchmark and measure the performance of your system as well as offer monitoring and diagnostic features.

Graphics Card Holder

Additionally, a graphics card holder is included with the Crosshair VIII so you can stabilize heavier GPUs.
