Performance Features:

PERFORMANCE
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 Extreme 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.
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.
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.

UEFI BIOS
The renowned ROG UEFI (BIOS) provides everything you need to configure, tweak, and tune your rig. It offers intelligently simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned veterans.
Differential Senting
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. Maximus XII Extreme features a differential-sensing circuit and delicate IC that simplify overclocking and tuning by allowing you to track voltages more accurately.
CONNECTIVITY
ROG Maximus XII Extreme offers advanced connectivity, including WiFi 6 (AX201) and dual Ethernet with intel® 1Gb and Marvell® 10Gb Ethernet port to eliminate bottlenecks so you can enjoy exceptionally smooth online and LAN play. Additionally, the M.2 supports Intel® Optane™ Memory 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.
Networking

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 w/ ESS DACs, Op Amp and Nichicon Caps
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.
