Asus ROG Crosshair VIII Extreme X570 Motherboard Review

For Those Who Dare

Asus ROG Crosshair VIII Extreme

If you have to look twice at the ROG Crosshair VIII Extreme name containing both ‘Crosshair’ and ‘Extreme’ we don’t blame you. The flagship ‘Extreme’ moniker has been almost exclusively reserved for Intel platforms since its debut in 2007 on the Intel X38 based ROG Maximus Extreme. When the first-generation Ryzen bombshell dropped on the almost decade-long Intel party, Asus capped their AMD X370 board lineup with the Crosshair VI Extreme. While it was ‘extreme’ in name, It was really closer to an E-ATX Crosshair Hero with an extra M.2 slot and a few extra USB ports and lacked the over-the-top feel that the Intel Extreme boards had.  Zen+ and Zen2 came and went with no further Extreme boards announced and even Zen 3 arrived with the X570 chipset and Still no new red Extreme in sight.

With the annual board refresh that seems to happen during stagnate market periods (like those that happen during a global pandemic), ASUS decided to throw down in a big way with the ultimate Ryzen ready X570 motherboard. The ROG Crosshair VIII Extreme features, well, everything, and then a little more for good measure. For those power users that demand the absolute best with exactly zero compromises, the C8E delivers in every way. Featuring no less than five M.2 gen 4 slots and six SATA ports, storage is more than handled. Networking? how about 2.5Gb Ethernet, 10Gb Ethernet, and Wi-Fi 6E? Dual Thunderbolt 4 ports on the rear and tons of USB round out connectivity, including a USB 3.2 gen 2×2 20Gbps front port that supports up to 60 watts of power delivery.

Tons of water-cooling and Extreme overclocking features can be found onboard from the integrated water block, temp probe, and flow meter connectors to the Safe Boot and Retry Buttons to ASUS’s Q-Code and Q-LED displays for rapid problem-solving. The massive 2” LiveDash display can walk you through POST and Boot issues, and then can switch over to display important system information or even your own animations. If you are looking for the very best performance, Asus includes their Dynamic OC Switcher so you can have the best Single Thread manual overclock, as well as PBO-powered multi-threaded performance. Given how heavy the board and box already are, Asus chose to forgo the kitchen sink but included everything else you can imagine. Let’s dive in!

The ROG Crosshair VIII Extreme includes LiveDash, a built-in 2-inch OLED panel that shows useful information and features customizable graphics. During the power-on, self-test (POST) phase, the OLED shows key stats in simple language using traditional POST codes. In normal operation, the panel can be programmed to show CPU frequency, device temperatures, fan speeds, or water-cooling information. You can also personalize the default OLED GIF with a preferred image or animation.
