ROG Maximus XII Extreme
Expertly tuned by our ROG Engineers to bring you the ultimate performance. Made to be extreme as the name suggested, is positioned for max performance water-cooling enthusiasts. Combining hardware and software, to achieve optimized overclocking, high-speed memory support and comprehensive water and fan cooling controls, Maximus XII Extreme delivers ultimate performance combined with efficient, reliable operation.
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.
PERFORMANCE
Maximus XII Extreme is the ideal foundation for your dream gaming build. An intelligent voltage-regulator module (VRM) design and high-quality components ensure that you'll get the most out of demanding latest-generation Intel processors. More firepower and an overclocking edge are yours with Maximus XII Extreme.
COOLING
Featuring premium components, multiple fan headers and a bundled fan extension card, Maximus XII Extreme is fully equipped to enable higher performance at lower temperatures. To ensure system stability under heavy CPU loads, Maximus XII Extreme employs large VRM and chipset heatsinks that strike the right balance between surface area and mass. The extra-large heatsinks also cover multiple M.2 slots.
Optimization
ROG provides the tools needed to optimize your system quickly and easily. For those who relish complete control, the UEFI BIOS offers advanced customization options so you can tweak every aspect of your system.
CONNECTIVITY
ROG Maximus XII Extreme offers advanced connectivity, including WiFi 6 (AX201) and dual Ethernet with intel® 2.5G Ethernet and 10G port to eliminate bottlenecks so you can enjoy exceptionally smooth online and LAN play. Additionally, the M.2 supports Intel® VROC technology to maximize the speed of your SSD for faster load times, and SupremeFX on-board audio provides superb sound, while saving a PCIe slot.
Personalize
In addition to extraordinary performance, Maximus XII Extreme provides extensive styling and customization options to let you build a system that truly stands apart.
OLED
ROG Maximus XII Extreme motherboards is equipped with LiveDash, a built-in 2” OLED panel that displays useful information and customizable graphics. During the power-on, self-test (POST) phase, OLED shows key progress stats in simple language, using traditional POST codes. Then, during normal operation, the panel shows a choice of CPU frequency, device temperatures, fan speeds or information from the Water-Cooling Zone. You're also able to customize the default OLED GIF, so it'll display your own image or animation.

ASUS Optimem III
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 Extreme with your favorite modules and maximize throughput of the new 10th Generation Intel® Core™ Comet Lake-S processor for applications that demand massive bandwidth.
Fan Extension Card II
ROG Maximus XII Extreme includes the new Fan Extension Card II, which adds six headers that area controllable via FanXpert 4. The card features three temperature-sensor headers to complement the one available onboard, and also comes with three thermistors that can be affixed to different components. In addition to supplying extra headers for cooling, it provides three RGB headers to provide illuminated effects for your RGB fan.
Screw holes allow you to mount the card to the 2.5-inch bay on your chassis.
The ASUS Node connector allows you to connect additional compatible PSU or accessories.
Onboard WiFi 6 (802.11ax) supports ultrafast wireless-networking speeds, improved capacity and better performance in dense WiFi environments, providing exceptional online gaming experiences. *
Designed to meet the demanding requirements of power users and content creators, 10 Gbps onboard Ethernet provides a new level of home networking. With up to 10X the bandwidth of standard gigabit Ethernet, you'll enjoy streaming uncompressed 4K UHD videos, and backups and file transfers that are faster than ever before. **
Onboard Intel 2.5G Ethernet gives your wired connection a boost, with up to a 2.5X improvement over standard Ethernet connections for faster file transfers, smoother lag-free gaming and high-res video streaming.
Two front-panel USB 3.2 connectors area ready to accommodate a wide variety of devices.
Reversible USB 3.2 Gen 2x2 Type-C™ ports provide ultimate flexibility and blazing data-transfer speeds.
At a breathtaking 40Gbps you'll experience faster transfers, with four times (4X) the data speeds of any other cable and twice (2X) the video bandwidth.
Storage
Maximus XII Extreme supports up to four onboard M.2 drives to maximize storage. Two can be found on the ROG DIMM.2 module, next to the memory slots, and supports drives as long as 110 mm. The other two can be found under the aluminum heatsink cover. PCIe support ensures compatibility with the very latest NVMe SSDs for ultrafast transfer speeds.
ROG DIMM.2
The ROG DIMM.2 module is an innovative expansion card that allows two M.2 drives to be connected via a DDR4 interface. You can then add a metal heatsink, helping to control thermals for maximum performance while elevating the aesthetics.
SupremeFX
ROG SupremeFX audio technology has levelled up, delivering an exceptional 113 dB signal-to-noise ratio on the line-in connection to provide best-ever recording quality. There's also a low-dropout regulator for cleaner power delivery to the SupremeFX S1220 codec, an ESS® ES9023P digital-to-analog converter for superior front-panel output, and a Texas Instruments® RC4580 op amp for high gain with low distortion — all to deliver audio that envelops you as never before.
