Design & Features

The Maximus X Hero, part of the Republic of Gamers lineup, boasts a bold design and many gamer-friendly features. It resembles the Maximus X motherboard but has a stylish heatsink cover over the M.2 port beneath the CPU socket.

A stylish shroud on the left side, extending from the top down to the Audio hardware, adds a touch of sophistication in gray plastic. The I/O ports are covered by a sizable bulkhead featuring RGB LED-lit MAXIMUS X on top and embossed SupremeFX below. Three screws secure this shroud from the backside, providing easy removal for customization.

Right next to this Asus Rog Maximus x hero review shroud is an aluminum-based heatsink covering the VRMs. It has a grey color thermal pad for heat conductivity. Its design depicts that of the Asus ROG concept. Similarly, another aluminum-based heatsink is right on the top side of the CPU socket. It has HERO printed on it elegantly. There are black lines on its top greyish surface. It is also covering the VRMs and has a thermal pad underneath it.

The I/O shield is pre-mounted on the motherboard. ROG’s patent-pending I/O shield can withstand electrostatic discharge up to 12kV. Its sleek new design looks as good as it performs.

Let’s take a look at the connectivity options on the I/O side:

• 1 x DisplayPort
• 1 x HDMI
• 1 x LAN (RJ45) port(s)
• 2 x USB 3.1 Gen 2 Type-A + USB Type-CTM
• 4 x USB 3.1 Gen 1 (blue)
• 2 x USB 2.0
• 1 x Optical S/PDIF out
• 1 x Clear CMOS button(s)
• 1 x USB BIOS Flashback Button(s)
• 5 x Gold-plated audio jacks

The left side has the EATX12V power connector for the CPU. Moving right, there are three 4-pin PWM fan headers: AIO_PUMP, CPU_OPT, and CPU_FAN, which aid in cable management. Next is the AURA RGB Header2 for LED strip connection. On the top right, the Q-Code Debug LED helps with troubleshooting.

This board features the Intel LGA-1151 socket but doesn’t support Skylake/Kabylake CPUs on 8th-generation motherboards. It’s designed for large coolers and has “Foxcon LGA115X” on the CPU socket cover. Keep the cover’s instructions safe for reference. Around the socket are 23 capacitors.

You’ll find a grey heatsink with “Republic of Gamers” printed below the CPU socket and an Aura RGB LED underneath. This smart Asus design covers the first M.2 socket, providing excellent cooling with a thermal pad for M.2 SSDs.The M.2 socket supports PCIe 3.0 x4 and SATA mode M Key, accommodating type 2242/2260/2280 PCIe storage devices. To install the M.2 SSD, remove the heatsink by unscrewing the two black screws. Before reattaching, peel off the thermal pad cover.

 

To the left of the heatsink, you’ll find a 4-pin PWM fan header labeled CHA_FAN1. Right beside this header is the LED_CON1, where you plug in the power cable coming from the plastic shroud over the I/O ports. This setup is what powers the MAXIMUS X’s Aura RGB LED, lighting it up from underneath.

The DIMMs are positioned on the right side of the CPU socket, ensuring clearance. Asus uses a Q-notion for board features, calling DIMM slots Q-DIMMs.DIMM ends are fixed near PCIe slots; one end has a latch. To remove RAM, push and pull.Maximum 4 DIMMs, 64 GB capacity, DDR4 with 288 pins, 2400MHz speed (JEDEC). Supports up to 4133MHz (OC). Non-ECC, un-buffered DDR4 with Dual Channel, Intel® XMP supported. Asus adds protection with resettable fuses against overcurrent and short-circuit damage for DIMM slots.

Right next to DIMM slots from the top side, there are 4 indicator LEDs labeled CPU, DRAM, VGA, and BOOT in that order. In case of any issue with the corresponding component, the LED will continuously light up.

Each LED has the following color configuration:

• Red for CPU
• Yellow for DRAM
• White for VGA
• Yellow Green for BOOT

The Mem OK button on the motherboard resolves DRAM incompatibility. If the DRAM_LED stays lit, press and hold this button until the LED blinks, initiating a compatibility mode for successful booting. Note: This button doesn’t function in Windows. Below it, you’ll find a 3D Mount point, followed by a 24-pin EATXPWR header.

On its left side is a USB 3.1 Gen 2 header for front panel USB 3.1 connectivity. The chassis now features a USB 3.1 header for front panel USB. Asus takes it further with a USB 3.1 Gen 2 header using 3 PCIe Gen 3 lanes, offering a max bandwidth of 2GB/s. This anticipates faster front panel data transfer speeds.

Down the road, there’s a powerful 4-Pin Hi-Amp PWM fan header at 3A, while others are at 1A. Below is a Hard Drive LED. You’ve got 6 SATA 6G ports for RAID 0, 1, 5, and 10 using Intel Rapid Storage Technology. These default to AHCI mode, which is changeable in the BIOS. Also, a 4-pin PWM CHA_FAN2 and a W_PUMP+ header at 3A. Look for the Water Flow header in white.

A second M.2 socket on the left side of the W_FLOW header. This socket supports PCIe 3.0 x4 M key design and type 2242 / 2260 / 2280 PCIe storage devices. On top of it, we have another beautiful two-toned heatsink cover for the chipset. It has Aura RGB LEDs underneath it and a thermal pad for effective heat dissipation from the chipset. A silver ROG Eye logo on the bottom side of the chipset also lights up.

PCIe Slots

Let’s take a look at the PCIe slots. This Asus Rog Maximus X Hero review board has 6 PCIe slots. Slots 1, 3, and 5 from the top are PCIe Gen 3.0/2.0 x1. The second slot is PCIe Gen 3.0/2.0 x16. This slot is electrically x16 implemented and connected with the CPU. This is the only slot with x16 speed on the board. The fourth slot is PCIe Gen 3.0/2.0 x8. The sixth slot is PCIe Gen 3.0/2.0 x4, taking PCIe lanes from the chipset. Please note that in the case of two SLI or CF, slots 2 and 4 will operate at x8/x8 speeds.

These slots have been designated as:

Slot No	Description
1	PCIEX1_1
2	PCIEX16/x8_1
3	PCIEX1_2
4	PCIEX8_2
5	PCIEX1_3
6	PCIEX4_3

Audio Hardware

Audio hardware is implemented to the left side of the PCIe slots and extends towards the bottom of the PCB. SupremeFX, Asus’ on-board audio solution for ROG motherboards, enhances audio with features like a low-dropout regulator for cleaner power, an ESS Sabre Hi-Fi ES9023P DAC for superior front-panel output, and a Texas Instruments RC4580 op-amp for high gain with low distortion.

It offers 10 DAC Channels, simultaneous 7.1 channel playback, independent 2.0 channel, and multiple-stream stereo to front-panel outputs, powered by Nichicon capacitors and a precision clock source. The RC 4580 buffer ensures true-to-life tonality and sound imaging. Supported by Sonic Suite III and Sonic Radar III software, users can customize sound and gain an edge in gaming by pinpointing enemy positions.

AURA

AURA is all about RGB lighting on the motherboard. Asus provides software to control LEDs under main sections. Aura headers let users connect LED strips for coordinated chassis lighting. AURA Sync takes it further, syncing the motherboard, graphics cards, peripherals, and LED strips for a unified color effect.

On its left side, we have a second Aura RGB Header (+12V GRB, 5050 format, 2A, up to 2m), Fan Extension connector (supports 3 fans, individual control), two-pin thermal sensor header (probe separate), 4-pin PWM CHA_FAN3 header, two USB 2.0 ports, and a USB 3.1 Gen 1 port.

Next is a TPM connector supporting the Trusted Platform Module system for storing keys, digital certificates, passwords, and data, with separate modules available. Following that is a SLOW_MODE switch, disabled by default, aiding stability during LN2-based cooling and extreme overclocking. An LN2 jumper, disabled by default, combats cold boot issues during LN2 overclocking. There’s a ReTry reboot button with retained settings, a SAFE_BOOT button for BIOS safe mode, and Reset/Start buttons for convenient PC control. Lastly, an Aura Addressable RGB LED header and Front Panel HD Audio connector are featured.

The Asus ROG Maximus X Hero review highlights the long-time use of Digi+ technology for power delivery, featuring ASUS Digi+ Power Control (ASP1400BT A1728A), compliant with Intel’s IMVP8 specifications, with a PWM controller managing 10 power phases and 8+2 power phases for stable overclocking and robust power delivery.

Storage Test

Gaming Test

I have tested 5 games on the test build. All the games were tested with their highest graphics settings except that of MSAA, which was 4x where applicable.

Asus AiSuite III

Asus has bundled software in the provided CD. I’ll discuss AiSuite III here as it’s a versatile tool for overclocking, fan control, and software updates. The interface has One one-click overclocking and three modes: Performance, Power Saving, and Away Mode. 

Fan Xpert configures chassis fans with pre-built profiles. TPU handles detailed CPU overclocking. 5-Way Digital Optimization automates CPU overclocking with stability testing. Other features include Turbo App, PC Cleaner, EZ Update, USB BIOS Flashback, and File Transfer for wireless file exchange. In short, AiSuite III is a powerful tool for easy and efficient system optimization.

Overclocking and Thermals

I tested the chip’s overclocking capabilities. It easily reached 5.0GHz at 1.30V VCore. I pushed it to 5.1GHz with 1.32V VCore, passing the stress test. The system booted up at 5.2GHz (1.350V VCore), and Cinebench ran successfully, but the stress test failed. For higher speeds, a custom loop cooling solution is recommended. Note that each chip’s thermal characteristics vary, and hitting or exceeding 5.0GHz is not guaranteed—it’s a silicon lottery.

Using Noctua NH-D15 for cooling, the stress test at stock clocks reached a max of 61°C. The stability test for 5.0GHz hit 81°C under stress, monitored with Asus RealBench 2.4 and RealTemp at a 20°C room temperature. Cinebench yielded a CPU score of 1687.
