Teamed Power Architecture

Today's CPU architectures place incredible demands on motherboard power design by transitioning from deep power-saving modes, going from lower-power mode to full load in an instant. The latest ROG VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.

A brief history
A shift in CPU demands
Bucking the trend
Thermal performance
High-quality components

While doublers help extend the number of effective phases, they do so at the cost of a processing delay. The teamed architecture allows two power stages to work in tandem to provide more power to the CPU. The MOSFETs within the power stages generate the most heat as they are responsible for voltage conversion and delivery to the CPU from the 12-volt EPS connector.

ASUS became the first manufacturer to implement phase-doublers with 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 led to phase-doublers becoming universally accepted in the industry, and they are still used for similar purposes today.
Modern CPUs pack more cores than their predecessors, and the latest instruction sets allow them to crunch computationally dense workloads at an incredible pace. In addition, they consume less power at idle and can transition between load states much more quickly. These improvements necessitate a re-evaluation of power-design priorities because phase-doublers add a propagation delay that hampers transient response.
Fortunately, 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 Maximus Z790 Apex Encore 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 and phase-doublers control the circuit, and the power stages do the heavy lifting from an electrical and thermal standpoint. The power stages feature low RDSON to reduce switching and conduction losses, helping to improve overall thermal headroom.

MEMORY

Comprehensive memory tuning options are the cornerstone of ROG motherboards. With the ROG Maximus Z790 Apex Encore, you can extract all of the potential out of your DDR5 modules, regardless of if they're from an extreme-speed kit or an entry-level set that would otherwise be locked.

DDR5 DOMINATION
DIMM FLEX
AEMP II

ROG has a long legacy of flexing the fastest memory performance, and DDR5 is no outlier. Thanks to improved signal routing, now enthusiast-grade kits have been driven as far as 8 GT/s on the Maximus Z790 Apex Encore, and who knows how far future DIMMs can go? Seasoned veterans can test their mettle by tinkering with the extensive array of tuning options in the UEFI.

The ROG Maximus Z790 Apex Encore is also equipped with the ROG Memory Fan Kit – a cooling solution to solidify DDR5 stability and unleash memory overclocking. With the ROG Memory Fan Kit, your DDR5 modules can push the boundaries and reach overclocking speeds of 8400+ MT/s. Experience superior cooling performance and unlock the full potential of your memory with ease.

The ROG Maximus Z790 Apex runs DDR5 memory at speeds up to 8000MT/s and higher.

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.

The ROG Maximus Z790 Apex Encore features Aura Sync.

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.

*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 true to life.

Through the pre-loaded DTS^® Sound Unbound™ app, the ROG Maximus Z790 Apex Encore envelops you in rich audio, conjuring whole new levels of immersion for extraordinary gaming and entertainment experiences. By exploiting Microsoft spatial sound technology, DTS Sound Unbound creates an audial 3D space — putting you right in the middle of the soundscape, where you can sense the location and direction of every gunshot, footstep, or other sound in your virtual environment.
* DTS Sound Unbound requires in-game support. Check with developers for supported titles.
