ROG Crosshair VIII Extreme
The ROG Crosshair VIII Extreme combines the best elements of the renowned ROG X570 motherboard lineup into a single beastly package amped to elevate Ryzen-based builds beyond all boundaries.

PERFORMANCE
Advanced engineering and menacing power lay the foundation for the ROG Crosshair VIII Extreme to thrive where others choke.

Teamed Power Architecture
Modern CPU architectures up the ante for motherboard power design by transitioning from deep power saving modes to full load almost instantaneously. The latest ROG VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.

ASUS became the first manufacturer to implement phase doublers in the A8N32-SLI Deluxe motherboard back in 2005. The board’s VRM was lauded for elegantly overcoming the power-handling capabilities of components that were available at the time while also reducing voltage ripple. Those benefits lead to phase doublers becoming universally accepted in the industry, and they are still used for similar purposes today.

Today’s CPUs pack more cores than their predecessors, and the latest instruction sets allow them to crunch computationally dense workloads at an incredible pace. As an added bonus, these processors also consume less power at idle and can transition between loads states much more quickly. These improvements necessitated a re-evaluation of power design priorities, because phase doublers add a propagation delay that hampers transient response.

The latest integrated power components can handle higher currents than the devices of yesteryear, making it possible to implement a simple circuit topology that isn’t hamstrung by the processing lag of phase doublers. That’s why the ROG Crosshair VIII Extreme utilizes teamed power stages to deliver higher burst-current per phase, while maintaining the thermal performance of phase-doubled designs.

Each VRM component serves a specific purpose. PWM controllers control the circuit, and the power stages do the heavy lifting from an electrical and thermal standpoint. That's why ROG Crosshair VIII Extreme utilizes 20 power stages. The high-end power stages feature a low RDSON to reduce switching and conduction losses, helping to improve overall thermal headroom.

ASUS OptiMem III
With proprietary memory trace layout tweaks that improve signal integrity and mitigate noise, OptiMem III allows memory kits to run at lower latencies and reduced voltages while operating at higher frequencies. Stack the ROG Crosshair VIII Extreme with your favorite modules and maximize AMD Zen 3 processor throughput for applications that demand massive bandwidth, or balance infinity fabric and memory performance for a diverse range of workloads.

DYNAMIC OC SWITCHER
Dynamic OC Switcher gives Ryzen processors newfound agility to crush multi-threaded workloads and slice through single-threaded apps. Simply configure a manual overclock for heavy tasks and then select a current threshold for Dynamic OC Switcher to automatically flip between your profile and AMD Precision Boost Overdrive (PBO).
