ASUS ROG Crosshair X670E Hero Motherboard Review

Today we’ll be taking a look at one of Asus’s flagship AM5 motherboard – the ASUS ROG Crosshair X670E Hero. It utilizes AMD’s high-end X670E chipset and supports all the latest AMD Ryzen 7000 series of processors on the new AM5 socket (LGA1718).

The motherboard features a massive 18 + 2 teamed power solution rated for 110A per stage, allowing rapid swing current, while maintaining exemplary thermal performance and stability. It supports the new PCIE 5.0 standards for both graphics cards and M.2 NVME SSDs, as well as supporting DDR5 ram (with EXPO support) with speeds of up to DDR5-6400MHz+ (OC)

For storage, it comes with a total of 6 x SATA3 ports, and 4 x M.2 slots for SSDs. These include 2 x PCIE 5.0 (Gen5) M.2 slots, 2 x PCIE 4.0 (Gen4) M.2 slots, and 1 x PCIE 5.0 (Gen5) M.2 Card.



For connectivity, it comes with the Intel 2.5G LAN and WiFi 6E + Bluetooth 5.0. For audio, it features the SupremeFX ALC4082 audio codec and ESS  ES9218 QUAD DAC high-definition DAC.

As far as expansion is concerned, the motherboard 2 x PCIe 5.0 x16 slots (supports x16 or x8/x8 mode(s)* and 1 x PCIe 4.0 x1 slot.  And for USB, there’s loads … a total of 23 x USB ports!

Rear USB (Total 12 ports) including …

  • 2 x USB4 (2 x USB Type-C),
  • 1 x USB 3.2 Gen 2×2 port(s) (1 x USB Type-C),
  • 9 x USB 3.2 Gen 2 port(s) (8 x Type-A + 1 x USB Type-C)

For front USB (Total 11 ports) includes …

  • 1 x USB 3.2 Gen 2×2 connector (supports USB Type-C with up to 60W PD/QC4+)*
  • 2 x USB 3.2 Gen 1 headers) support additional 4 USB 3.2 Gen 1 ports
  • 3 x USB 2.0 headers support additional 6 USB 2.0 ports.

You also get the diagnostic LEDs, onboard power-on and reset button, PCIe Slot Q-Release, M.2 Q-Latch and a bunch of Asus ROG special features … all of which makes this motherboard truly stand out from the crowd.

And there’s plenty of options for RGB lighting including 3 X 3-pin addressable Gen2 RGB headers, 1 x 4-pin Aura RGB header, as well as I/O Zone Polymo lighting.


As you can see from the above, the Crosshair X670E HERO motherboard (and their EXTREME model) from Asus, not only looks great,  but also comes absolutely packed with a ton of enthusiast-grade features. But be warned, there have been loads of Reddit posts about memory compatibility issues with EXPO certified memory kits. For memory compatibility and QVL (qualified vendors list), I recommend you check out Asus’s QVL page here.

he X670E chipset is AMD’s enthusiast-grade, and currently their highest-end chipset supporting all the latest Ryzen 7000 series of processors on the new AM5 socket (LGA1718). It features a load of new technologies, but most notable is the supports DDR5 memory, and of course the latest PCIE 5.0 standard for both GPU and M.2 SSDs. As I mentioned before, this could this be one of the most significant next-generational jump in performance for AMD. Let’s take a closer look below …


AMD X670E Chipset

When only the fastest will do, an AMD X670E motherboard delivers. Featuring dual-channel DDR5 memory, AMD EXPO™ technology and PCIe® 5.0 support for both graphics and NVMe, you can play the most demanding games  and deliver your biggest projects with the revolutionary performance of an AMD X670E motherboard and AMD Ryzen™ 7000 Series processors

The X670E chipset allows a total 44 usable PCIE lanes, with upto a maximum of 24 lanes for PCIE 5.0. It can support NVME PCIE 5.0 x4 slot for SSDs and PCIE 5.0 x16 slot for the latest next-gen graphic cards. It’s also capable of up to 12 x SUPERSPEED USB 10Gbps and up to 2 x SUPERSPEED USB 20Gbps.

I would like to thank ASUS for providing the review sample. This is what ASUS has to say about themselves on their website:

Our Mission – Delivering the perfect user experience

Unite gamers of diverse backgrounds to achieve their potential together in play. Through innovative technology and exceptional experiences, we can push boundaries to create a world without limits.


Our relentless drive to sharpen the cutting edge has reshaped the world of gaming technology. By leading the charge to adopt the latest technologies, ROG sets standards across the entire industry of gaming systems and PC components


In 2006, an elite team of ASUS engineers and designers committed to creating the world’s best gaming experiences came together to start the Republic of Gamers (ROG). Since its founding, ROG has set new industry standards creating innovative, hardcore gaming gear that empowers gamers and enthusiast everywhere.


The story begins with the groundbreaking ROG Crosshair motherboard, which was the first to put advanced overclocking settings in a user-friendly BIOS. Intuitive tweaking and cooling options enabled experts and novices to easily maximize performance and optimize acoustics. ROG motherboards are still defined by this flexibility, and feature increasingly refined aesthetics with tasteful RGB accents.


Our pursuit of performance led to graphics cards with advanced tweaking and cooling upgrades. ROG started with air cooling, added support for custom loops with the hybrid Poseidon series, and eventually made liquid cooling self-contained. In 2009, we shocked the world by planting two GPUs on a single graphics card to create the Mars series, which set a new standard for graphics power in a single card.


ROG enabled smoother gameplay by working closely with NVIDIA® to co-engineer G-SYNC™ technology that improves how GPUs and displays interact. We were the first to overclock panels up to 165Hz and beyond, and first to pair them with super-narrow bezels that enhance multi-monitor configs and overall immersion. Our diverse display portfolio also brought high refresh rates to 4K and ultra-wide monitors.


Laptops first took ROG DNA on the road in 2008 with the G70, a powerhouse desktop replacement featuring dual GPUs and two displays. The ROG Mothership redefined that form factor with an innovative detachable design. Our latest innovation elevates gaming laptops with a rising secondary screen, and it’s part of growing Zephyrus family that eliminates compromises for smaller and slimmer devices.


ROG got into complete desktops with the massive TYTAN, which opened extra cooling vents and increased CPU clocks at the touch of a button. Since then, our lineup has grown to include an array of machines with complete system cooling optimized for different sizes, like the small form factor ROG Huracan G21, whose magnetic side cover folds away to enhance airflow and achieve higher performance.


Adding peripherals allowed us to complete a full battlestation with the precise input and control hardcore gamers expect. We bring ROG enhancements in every category, from swappable switches that customize the feel of gaming mice, to tweaked layouts that tailor mechanical keyboards for intuitive accuracy, and advanced AI noise cancelling technology that improves vocal clarity for gaming headsets.


ROG’s commitment to perfecting the gaming experience extends to a complete ecosystem of peripherals, components, and devices that communicate with and enhance each other. Examples include Aura Sync, which coordinates RGB lighting across an entire environment, and the ROG Rapture router, which accelerates gaming packets and can combine with other ROG routers to form a whole-home mesh network.

We’ll be testing the ASUS ROG Crosshair X670E Hero Motherboard with an AMD Ryzen 9 7900X (AM5) processor at default speed, along with 32GB of Patriot Viper Gaming Venom DDR5-6200, Lexar NM800 Pro 2TB PCIE Gen4 SSD, and an EVGA GeForce RTX 3090 graphics card. I’m expecting excellent performance from the above test rig, but let’s find out if our memory will work with XMP/EXPO profiles enabled.

OK, let’s dive straight in and begin by taking a look at the specifications and features in our next page.

You can buy the ASUS ROG Crosshair X670E Hero motherboard for around USD $699 from Amazon –
