Maximus XII Formula

ROG Maximus XII series motherboards are designed to explore the upper echelons of gaming and overclocking. The Formula is plumbed for custom liquid cooling and includes other enhancements to punctuate premium systems. The CrossChill EK III VRM block, co-developed with EK Water Blocks, help cope with higher VRM loads associated with Intel Comet Lake CPUs. Aesthetically, Maximus XII Formula has a stealthy black finish with intricate patterns cut into its reflective armor. The latest-generation Formula is all set to make your showcase rig shine.

Intelligent Motherboard

Our ROG engineers developed and extensively-tested intelligent software solutions to ensure your system stays in optimal condition.

  • AI Overclocking

    Tuning is now faster and smarter than ever before. AI Overclocking profiles the CPU and cooling to predict the optimal configuration for each system.

  • AI Cooling

    AI Cooling automatically manages and controls motherboard-connected fans, ensuring the most efficient settings depending on the current system load and temperature.

  • AI Networking

    GameFirst VI optimizes and organizes network bandwidth, effectively reducing jitter and eliminating spike lag to ensure smooth online gameplay.


The Intel Comet Lake processor features 10 cores and a peak single-core Turbo speed that exceeds 5.3 GHz right out of the box. To cope with this increased demand on the system, Maximus XII Formula takes advantage of its intelligent VRM design and uses quality components to ensure the best gaming and daily productive computing experience.

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. Our latest VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.


Boasting proprietary memory trace layout tweaks that improve signal integrity and mitigate noise, ASUS OptiMem III is more compatible with 3600 MHz+ memory kits, allowing them to run at higher frequencies. You can opt to optimize memory for high frequency settings, or low latency settings. With higher capacity memory kits, OptiMem III enables you to run at maximum frequency, whereas other motherboards will trade off frequency for capacity. Stack Maximus XII Formula with your favorite modules and maximize throughput of the new 10th Generation Intel® Core Comet Lake-S processor for applications that demand massive bandwidth.


The focus on maximizing performance would be futile without similar dedication to improving the cooling that allows systems to sustain faster speeds. The CrossChill EK III VRM block enables Maximus XII Formula to cope with the high VRM loads of ten core CPUs. The hybrid cooling system sits atop of a heatpipe that’s directly linked to the extended VRM heatsink, giving it cooling capabilities that surpass the requirements of this current generation.


Maximus XII Formula is packed with intuitive and flexible tools to allow customization across all system parameters to deliver the performance you want.


Maximus XII Formula is well equipped to deliver supersmooth wireless connectivity and compatibility with multiple input sources and PCIe extensions, all of which are a must-have for gaming setups.


In addition to extraordinary performance, Maximus XII Formula provides extensive styling and customization options to let you build a system that truly stands apart.
