For many years, ASUS has been a leading motherboard partner of AMD, with its ROG Crosshair platform at the forefront. We use the word “platform” here because, over the course of the last 15+ years, this lineup has expanded from one motherboard to encompass Hero, Extreme, and Gene.

The new X670E Extreme is a major advance over the previous generation. Naturally, DDR5 and PCIe 5.0 are now supported, but ASUS has also included 40Gbps USB4, which can also be used as display outputs using Intel’s recently released JHL8540 controller.

While many would find that a motherboard costing $400 is all they need for a fresh build, other people desire the best, and there aren’t many motherboards that can match the ROG CROSSHAIR X670E EXTREME Motherboard for them. With all the functionality you could ask for, this $1000 board is the most feature-rich X670E board available. With features like integrated 40Gbps USB4, PCIe 5.0, and DDR5, this board is prepared to handle whatever task you give it.

Let’s address the obvious: not everyone requires a motherboard positioned in this manner. Many enthusiast boards available for $400 will fulfill the majority of your needs. At the top of the X670 series, the ROG CROSSHAIR X670E EXTREME Motherboard has all the features you could possibly need and more.

ROG CROSSHAIR X670E EXTREME Motherboard Packaging & Overview

The ROG branding and supported chipset are located down the bottom of Extreme’s board packaging, which is very distinct from that of any other Crosshair motherboard.

A picture of the board to the left with a port breakdown underneath is displayed on the back.

This board now has a somewhat altered appearance. A portion of the VRM heatsink is covered by the large Crosshair logo along the I/O plate. The socket and four memory slots are the next topics we cover. The board has an OLED screen underneath, and the m.2 slots are hidden beneath board armor.

The clear CMOS buttons and BIOS flashback are the first of many buttons on the packed rear I/O. This connects to our two LAN ports and then our initial group of USB 3.2 connections. The Wi-Fi 6e antenna connectors and analog audio outputs are located farther down.

With the exception of a few additional capabilities with the new platform, the EFI remains the same as previous boards. An overview of the CPU, RAM, and BIOS version is provided via the main menu. Setting EXPO for memory and overclocking is done entirely by extreme tweakers. Options for setting SATA and NVMe storage as well as other system devices are available in the advanced menu.

You may configure your fans either automatically or manually using the Monitor tab. The tool menu offers you the ability to erase your storage devices, update your BIOS, and create profiles.

Along with an amazing assortment of USB connectivity choices, the board has 22 ports available, two of which enable USB4/Thunderbolt 4. Additionally, the ROG Crosshair Extreme performs exceptionally well in terms of networking because it has Intel i225 for 2.5Gbe and Marvell AQC113 for 10Gbe.

It’s clear from looking at the ROG CROSSHAIR X670E EXTREME Motherboard design that this is a display-quality board. With its amazing anime matrix LED display that cycles through a succession of animations and text, this engineering marvel is an RGB enthusiast’s dream come true. It leaves spectators in awe.

Additionally, the Livedash OLED display offers succinct and easy-to-read details about the state of your computer, including crucial system parameters like CPU frequency and temperature. Customization is essential, and you can simply make it genuinely unique by swapping out the default GIF for a picture or animation of your choosing.

Beyond the glitzy screens, the ASUS ROG Crosshair X670E Extreme just has a fantastic appearance that lends strength and distinction to any new PC setup. Large crosshair branding that partially obscures the VRM heat sink is now present on the I/O panel. The M.2 slots that will keep your SSDs operating cool even when pushed to their limits are hidden by board armor, which also covers the power connector and four memory slots.

A feast for the eyes is produced by the ASUS ROG Crosshair X670E Extreme’s Aura Sync lighting, which adds an additional splash of color. This is especially true when combined with a high-quality AIO cooler.
