Optimal Cooling

ROG Maximus X Hero is equipped with a stylish, angular M.2 heatsink that keeps your SSD cool. By efficiently dissipating heat away from the M.2 area, ROG Maximus X Hero minimizes the possibility of the performance-sapping throttling that can happen when drives become too warm. The heatsink's angular design adds an eye-catching touch to any build, while the T-sensor detects temperatures in the vital M.2 area for instant monitoring.

Cooler By Design
ROG Maximus X Hero features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS

All The Connectivity You Need

2x2 802.11AC Wi-Fi with MU-MIMO
ROG Maximus X Hero is engineered with 2x2 dual-band 2.4/5GHz antennas for up to 867 Mbit/s* transfer speeds — and the very latest Multi-User MIMO (MU-MIMO) technology** to ensure that every connected user experiences the best wireless and online speeds!
* Actual speed varies, and Wi-Fi hotspot feature operates at 802.11a/b/g/n Windows 10 does not currently support Wi-Fi hotspot functionality
**Requires MU-MIMO-ready client

More throughput and less processing equals faster online play
Intel® Ethernet features the latest Intel® Ethernet (I219-V) for faster, smoother gaming. Intel Ethernet controllers have a natural synergy with their CPUs and chipsets, reducing processor overhead and offering exceptionally high TCP and UDP throughput, so there's more power for games and other tasks.

Dual PCIe 3.0 M.2 Card Slots
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbit/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible. You can use one of these M/2 Card Slots with Intel® Optane™ Memory to accelerate your HDD and SSD storage to incredible levels of 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 Generation 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.
