ASUS Crosshair VI Extreme (AMD X370) Motherboard Review

Here are key points about the ASUS Crosshair VI Extreme.


What's Hot


Component Quality: The VRM has such great component quality that the topside VRM temperature didn't even increase over 1C from idle to load in our controlled test suite. Instead, heat just spread. However, that isn't where quality ends. Many X370 motherboards, use slightly lower quality controllers such as Realtek wired NICs, type-C switches that lack CC logic, and even audio codecs almost a decade old, but the Crosshair VI Extreme doesn't do that. Instead, you get the latest and greatest controllers almost all over and very upgraded audio, and that's probably why the price of the motherboard is so high. The motherboard also feels very high quality and the rear PCB shield helps to strengthen the PCB.



Fan Control: Twelve headers, with the possibility of 15 if you use the fan extension card is what the Crosshair VI Extreme is capable of supporting. That high number of built-in headers is due to the new radiator fan clusters, which offer shared control over groups of four headers. The fan extension card adds three extra fan headers that are fully controllable and three temperature sensor inputs. ASUS also includes three thermistor cables for these temperature sensor headers, so you should be set for cooling down your beastly X370 rig.


Aesthetics: While the Extreme doesn't look all that different from the Hero when it's turned off, it does when you turn on the RGB LEDs. The motherboard incorporates RGB LEDs into the IO shield, but it also integrated addressable RGB LEDs into the rear of the PCB and in the FCH heat sink, which produce really neat effects. The Crosshair VI Extreme is currently the only X370 motherboard on the market to support an addressable/digital RGB LED header. The right-angled 24-pin power connector is also a very nice touch.


Dual x4 PCI-E 3.0 M.2 Slots: The Crosshair VI Extreme is the only X370 motherboard with dual x4 PCI-E 3.0 M.2 slots. ASUS achieves this by taking x4 PCI-E 3.0 from the CPU's x16 PCI-E 3.0 lanes meant for the GPUs, so you have a lot of options when it comes to storage.


Crazy Overclocking: There is no other X370 motherboard with as many overclocking features as the Extreme. It features everything from voltage read points to LN2 specific features to help the system survive and boot up at temperatures below -100C. The motherboard also has built-in features for enthusiast overclockers that sport custom water cooling setups, such as a custom water block sensor header and water speed and temperature monitoring headers.


What's Not


Very Expensive: The X370 Crosshair VI Extreme is almost $100 more expensive than the second most expensive X370 motherboard (which is the Crosshair VI Hero). At $349, it's as expensive as X399 or X299 motherboards.



Final Thoughts


The ASUS Crosshair VI Extreme is the most loaded X370 motherboard, with basically everything you might ask for to compliment your Ryzen 3, 5, or 7 CPU. It has the most features of any X370 motherboard I have seen as well as excellent component quality. Its VRM is extremely durable and powerful, as is the motherboard as a whole.




The Crosshair VI Extreme is also the most expensive motherboard, but that is because it has features that no other X370 motherboards have. Addressable RGB LED headers, dual x4 PCI-E 3.0 M.2 slots, support for up to 15 fan header, and a right-angled 24-pin power connector are just a few of the unique features the motherboard sports. However, it's also super easy to overclock on air/water and is designed for heavy duty extreme liquid nitrogen overclocking.


Overall, if you need the most loaded X370 motherboard you can find, the X370 Crosshair VI Extreme should definitely be at the top of your list.

The Bottom Line: ASUS' ROG Crosshair VI Extreme offers excellent performance, top-shelf component quality, and a ton of features not found on any other AMD X370 motherboard, but it does not come cheap.
