ROG Maximus XI Formula exhibits the sleek, refined and functional design that has become iconic in the Maximus motherboard series. With its distinctive integrated CrossChill EK 2” LiveDash OLED with more custom features III cooling block, intelligent overclocking software and a stunning polished-mirror finish, the latest-generation Formula is all set to make your showcase rig shine.

Building on over a decade of ROG engineering and refinement, Formula is the motherboard that lets you push the boundaries while keeping the thermals in check and under careful control.


By default, all of Coffee Lake's major bus frequencies are derived from the same reference clock, limiting the control and flexibility needed to harness the full overclocking potential of the platform. Maximus XI Formula features a dedicated onboard clock generator that supplies dynamic reference clocks to the CPU cores and major subdomains, giving you the freedom to coax every MHz of headroom from the system.

DDR4 4400MHZ+
Whether you're gunning for high memory frequencies or tuning timings for the lowest latency, Maximus XI Formula provides the tools you need to exploit the Coffee Lake architecture's full potential: carefully optimized trace pathways maintain signal integrity, and the acclaimed ROG firmware offers the necessary tweaks to ensure stability while maximizing memory performance. Load up with a high-density memory kit for heavy multitasking, or run a focused setup that delivers the bandwidth your favorite games and applications need. Any way you stack it, Formula has you covered.

To provide Intel's latest CPUs unfettered access to memory bandwidth, we've reimagined motherboard trace routing from the ground up. Our OptiMem II tech carefully maps memory signal pathways across different PCB layers to reduce vias and also adds shielding zones that significantly reduce crosstalk. And to further enhance overclocking headroom for fully stacked memory configurations, we've employed a highly customized T-Topology layout that delivers time-aligned signaling.



CrossChill EK III lets you cool with air and water. The redesigned cooling channels provide wider copper, delivering up to 37.2°C-lower MOSFET temperatures on water, and the standard G1/4" threaded fittings mean CrossChill EK III easily fits existing setups — so you can enjoy efficient, quiet cooling with the minimum effort.


ROG Maximus XI Formula features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

Fast, intuitive control is vital for effective command of your rig, so we've loaded ROG Maximus XI Formula with simple, flexible tools that let you tweak almost every system aspect. Enjoy intelligent automated tuning with 5-Way Optimization technology, or dive deep into the revered ROG UEFI BIOS to take full manual control. Formula also makes short work of fine-tuning everything from sonics to storage, so it's easy to get every perk of your system up to speed.


ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.

We created a proprietary algorithm that evaluates the capabilities of your CPU.

The onboard intelligence also watches system vitals like temperatures, fan speeds, and power draw to gauge cooling performance.

Utilizes onboard intelligence to perform automated clocking and provides target frequency and voltage estimations for savvy veterans that prefer manual tuning.

Take care of complex tuning with just one click. ASUS 5-Way Optimization is a system-wide tuning utility that overclocks the processor and tunes fan speeds to ensure the best balance between cooling and acoustics. The automated CPU tuning feature of 5-Way Optimization leverages the same onboard intelligence as AI Overclocking,but goes further by running a Prime95 based stress test to deliver a result that's well-tuned from the get-go.

The TurboV Processing Unit (TPU) Insight provides AI Suite 3 with the intelligence needed to automatically fine-tune voltages, monitor system stats, and adjust overclocking.

EPU Guidance
The Energy Processing Unit (EPU) Guidance enables system-wide power efficiency, automatically optimizing consumption to maximize savings.

Fan Xpert 4
Enjoy comprehensive control over fans, water pumps and all-in-one (AIO) coolers, via either Fan Expert 4 or our award-winning UEFI.

Digital Power Controls
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, switching frequency and power-efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.

Game Faster, Rank Higher
Intel's processors feature per-core tuning, and the ASUS Turbo app makes use of this feature by letting you assign applications to specific processor cores, prioritizing computing power where it's needed most.

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.
When you're ready for a deeper dive into the configuration of your system, delve into the UEFI's Advanced mode and take complete control. Each section is intuitively organized, and a built-in search feature makes it easy to find the options you need. Advanced functions are coded with the intelligence to adapt to your settings, and when you're ready to take charge, parameters have the granularity to dial in performance just the way you want.
