-
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.

Accurate Voltage Monitoring
Conventional motherboards use single-ended sensing circuits that are susceptible to noise and have to tap voltage rails from a location that isn’t ideal for accurate monitoring. These issues lead to a large disparity between the voltage fed to components and the values reported to software. The ROG Crosshair VIII Extreme features a differential-sensing circuit that rejects noise and takes readings directly from the CPU and the end point of major voltage rails. This simplifies overclocking and tuning by allowing you to track voltages more accurately.

Sonic Studio III
Sonic Studio supports HRTF-based (head-related transfer function*) virtual surround for headsets, casting an immersive aural landscape that draws you deeper into the action. The intuitive Sonic Studio interface also offers a range of EQ options and one-click presets, allowing you to tailor acoustics to suit personal preferences or the characteristics of your headset.
Learn more about Sonic Studio III
*A head-related transfer function is an audio algorithm derived from sound data recorded through a dummy head. Test tones are played from a spherical grid around the dummy head to obtain subtle changes in sounds that come from different directions. The results are combined into an algorithm that allows Sonic Studio's virtual surround to process sound that’s true to life.

AMD最後のラスボス!Zen3最強ゲーミングCPU? 強いのはFPSだけじゃない!Ryzen 7 5800X3D [超猫拳]
Unboxing Motherboard 15 juta | ASUS ROG Crosshair VIII Extreme
Mobo Ryzen TERBAIK. - ROG Crosshair VIII Extreme
The whole back is covered by a very nice aluminium cover, which has to be removed during installation. The back is very complete on the connectivity side which I really appreciated. In conclusion this is a very complete card aimed at those who already know what they are looking for and what to expect, finding the top of the top and the most complete possible on the market. It is in fact, in my opinion, one of the most complete X570 boards on the market.
AN SSD IN THE PLACE OF A RAM? THAT'S WHAT IT LOOKS LIKE ON THIS MOTHERBOARD
Video review from the channel TheTanelChannel. Rating 9/10
Video review from the channel HDTanel. Rating 9/10
This board is a real surprise for me too, because I really did not expect something like this from ASUS in this existing generation of Zen3 processors, I thought that AMD would get this treatment only with the next ZEN4.
