Dual PCIe 3.0 M.2 Card Slots
The ROG Maximus X Formula supports two M.2 drives, delivering lightning-fast transfer speeds of up to 32Gbps. The first slot sits neatly below the PCH heatsink, and accommodates M.2 drives of up to 110mm in length (type 22110). The second slot is placed at the lower edge of the board and is oriented for vertical mounting, taking advantage of chassis airflow to help keep your high-performance M.2 drive cool.

Intel® Optane™ Ready
Seriously improve your new PC's performance with an optional Intel® Optane™ Memory Stick. This new memory type is designed to optimise your System Caching to incredible levels, offering SSD-like performance from HDDs and even better performance from SSDs!

Best Gaming Performance

DDR4 RAM Overclocking Up To 4133MHz+
ASUS OptiMem preserves memory signal integrity by routing memory traces and vias to the optimal PCB layer, and our T-Topology layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements lead to more headroom for overclocking and improved stability, allowing memory speeds of DDR4-4133 and beyond with all slots populated.

A dedicated base clock (BCLK) generator that extends CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and base-clock overclocking control, providing the flexibility to extract every ounce of performance from 8th Gen Intel® processors.

5-Way Optimization

One-click overclock and cooling, done!
One click takes care of all that complex tuning. ASUS 5-Way Optimization makes your PC smart. It dynamically optimizes essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.

  • An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration
  • Fans stay whisper-quiet for everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks
  • All-new stress test that allows users to optimize and overclock for CPU or memory-centric workloads

Best Gaming Audio

ROG's awesome SupremeFX audio technology has levelled up, delivering an exceptional 113dB signal-to-noise ratio on the line-in connection; and that means our best-ever recording quality!

ASUS also added a low-dropout regulator for cleaner power delivery to the SupremeFX S1220 codec, an ESS® Sabre Hi-Fi ES9023P digital-to-analog converter for superior front-panel output, and a Texas Instruments® RC4850 op-amp for high gain with low distortion; which all adds up to audio that envelops you as never before.

Sonic Studio III
Sonic Studio supports HRTF-based (head-related transfer function*) virtual surround for VR headsets, casting an immersive aural landscape that draws you deeper into the action. The intuitive Sonic Studio interface also offers a range of EQ options, allowing you to tailor acoustics to suit personal preferences or the characteristics of your headset.
*A head-related transfer function is an audio algorithm derived from sound data recorded through a dummy head. Test tones are played from a spherical grid around the dummy head to obtain subtle changes in sounds that come from different directions. The results are combined into an algorithm that allows Sonic Studio's virtual surround to process sound true to life.

  • App-specific Profiles
    Apply customized audio settings to different applications, so everything you do is perfectly tuned to the way you want to listen.
  • Surround Sound
    Surround sound for a truly immersive audio experience
