Psyche up and engage the Dark Hero overclocker in you, with onboard intelligence to scan, predict, and adapt CPU performance parameters, and tools to command and track system vitals.
Tuning is now faster and smarter than ever before. ASUS AI Overclocking profiles the CPU and cooling to predict the optimal configuration and push the system to its limits. Predicted values can be engaged automatically or used as a launching ground for further experimentation.
Conventional motherboards use single-ended sensing tapped from a location that isn't ideal, leading to a large disparity between the actual voltage fed to the CPU and the value reported to software. The ROG Maximus Z790 Dark Hero features a differential-sensing circuit and delicate IC that simplify overclocking and tuning by allowing you to track voltages more accurately.
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.
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 Dark Hero 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.
Comprehensive memory tuning options are the cornerstone of ROG motherboards. With the ROG Maximus Z790 Dark Hero, 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.
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 far beyond the 8 GT/s mark on the Maximus Z790 Dark Hero, 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.
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.
ASUS Enhanced Memory Profile II (AEMP II) is an exclusive firmware feature that allows users to achieve supreme memory performance and compatibility with optimized clock speeds, even when they're using PMIC-restricted memory modules that do not provide an XMP or EXPO profile. Developed through a flexible training method, AEMP II simplifies the process of fine-tuning memory settings beyond the baseline configuration, all while ensuring system stability. This applies whether you are maximizing the potential of an entry-level module or preparing a high-speed kit for ultimate performance.Now, AEMP II offers even more flexibility. With the latest firmware update, AEMP II allows users to optimize the performance of a four-DIMM DDR5 RAM configuration, even with a mixture of different brands and dies. Increasing the memory capacity of your build by adding additional DIMMs has never been easier — with AEMP II, you can get optimized memory performance even when all four memory modules are not an exact match, provided that all four DIMMs have the same capacity.
A VRM heatsink on the MOSFETs and chokes is connected to the aluminum I/O cover via an embedded heatpipe to increase mass and surface area for dissipation.
Large aluminum heatsinks provide extensive surface area to cool mounted M.2 drives, and each of the three onboard slots has a dedicated backplate for additional heat dissipation.
Each thermal pad improves overall heat transfer from the system by bridging the heat generated by the power stages to the heatsink. For future maintenance, a replacement thermal pad can also be found in the package.
