Design of the X670E Crosshair Extreme
When taking the Asus flagship board out of the box, it’s instantly clear it’s a premium motherboard. From the sheer weight to the all-black motherboard that’s mostly covered in shrouds, it gives off a high-end vibe. The black VRM heatsinks are large and heavy, with mitered cutouts to increase surface area. Above the IO area, Asus uses the unique dot-matrix-like RGB display that rotates through a few default branding images. The right edge sports a shroud that covers all of the ugly headers and connectors along that edge. The bottom half of the board is also covered with heatsinks and shrouds. And above the chipset, another dot-matrix RGB area sports the ROG branding.
Starting with the top half of the board, we get a closer look at the RGB display and the massive heatpipe-connected heatsinks. Compared to the OLED screens we’ve seen on some flagship boards in the past, I’m not a fan of the dot-matrix look. However, the light it gives off is bright, and the colors are saturated, so it will still look good inside your chassis. Just above the VRM heatsink on the left are two 8-pin EPS (one required) connectors to power the processor.
Also, on the board's top edge, we run into our first three (of eight) 4-pin fan headers. All headers support PWM and DC-controlled fans/pumps. All CPU, Chassis, and Radiator headers are Q-fan controlled by default and support up to 1A/12W output. The two water pump headers (W_PUMP+1/2) handle up to 3A/36W and run out of the box at full speed.
Just below the fan headers are four reinforced DRAM slots, with a single locking mechanism on top. On top of the 128GB capacity, Asus lists support of up to DDR4-6400+(OC), the lowest of the flagship-class boards we’ve looked at. That is, seemingly, the maximum on most AMD boards anyway, so I wouldn’t worry about anything faster in the first place. The Crosshair Extreme handled our DDR5-5600 and DDR5-6000 kits without issue during our testing.
Normally, these high-end Asus boards have the DIMM.2 slot for additional M.2 support. However, with this generation, Asus uses a proprietary slot called GEN-Z.2 that adds Gen 5 and Gen 4 M.2 slots inside a heatsink shell. The Crosshair Extreme supports five M.2 modules using the onboard sockets and the two add-in cards (the other is a more standard AIC that connects through the PCIe slot).
The two-character debug LED and four-LED EZ debug features are on the right edge and help troubleshoot the POST process/non-boot situations. Moving down, we hit the start (power) and Flex buttons, a 3-pin ARGB header, two 4-pin fan headers, the 24-pin ATX power connector, the 6-pin PCIe PD connector for fast charging devices through the front panel Type-C port, and finally, a front panel USB 3.2 Gen 2x2 (20 Gbps) header that sits vertically.
Power delivery on the Crosshair Extreme is, fittingly, one of the more robust we’ve run across for the AM5 platform. Power comes from the EPS connector(s) onto the Digi VRM controller (ASP). From there, it moves on to the 20x SiC850A 110A SPS MOSFETs. The 2,200A available for Vcore is the second highest we’ve seen. You’ll only be limited by your cooling method on this board. It will handle ambient and sub-ambient overclocking without the VRMs holding things back.
On the bottom half of the board, we’ll start with the audio on the left side. Hidden under the heatsinks is a flagship-class Realtek ALC4082 codec. In addition to the audio separation line and dedicated audio caps, it also comes with an ESS SABRE9218C DAC and a USB Type-C to 1/8th inch DAC for non-USB headphones. If this audio solution isn’t good enough, you’re likely an audiophile with some seriously expensive equipment. For most users, this is more than good enough and about the best you can get on a modern motherboard.
In the middle of the board are two full-length PCIe slots, an x4 size slot, and two M.2 sockets. Both full-length slots are reinforced and connect via the CPU to offer PCIe 5.0 bandwidth. The top slot runs at x16 speeds, and the second full-length slot has a maximum of x8. With both active, it splits to x8/x8. The bottom x4 slot connects through the chipset and runs at PCIe 4.0 x4 speeds.
Mixed in among the shrouds are two PCIe 5.0 x4 (128 Gbps) M.2 sockets that support up to 80mm modules. There is some lane sharing among the PCIe slots and M.2 sockets. If M.2_2 is enabled, PCIEX16_1 (top slot) runs at x8, and the bottom slot runs at x4 speeds. You’ll be able to run all six SATA ports and all five M.2 sockets concurrently; you’ll just lose some bandwidth on the PCIe slots.
The rear IO plate on the Crosshair Extreme is busy. It comes attached to the board out of the box, which is what we expect from most higher-end boards these days. There are 10 total USB ports out back, with two USB 4 ports Type-C ports (JHL8540 USB4 controller), a 3.2 Gen 2x2 (20 Gbps) Type-C port, and a 10 Gbps Type-C port. In addition to the Type-C ports are eight other USB 3.2 Gen 2 (10 Gbps) ports. On the far left are the BIOS Flashback and reset CMOS buttons, while on the right are the Wi-Fi antenna connectors and the five-plug plus SPDIF audio stack (each analog port is backlit with matching color RGB). Last but not least, mixed in among the USB ports, are the 2.5 and 10 GbE ports.
Asus’ BIOS on the X670E Crosshair Extreme as we’re used to with other X670E. The BIOS sports the familiar black, red, and yellow ROG theme that’s easy to read. Asus starts in an Easy Mode that displays high-level information, including CPU and memory clock speeds, temperatures, fan speeds, storage information, etc. Advanced Mode has several headers across the top that drop down additional options. The BIOS is one of my favorites, as almost everything you need isn’t buried deep within menus.
Asus’ software suite is still the same as the Armoury Crate and AI Suite, but like the firmware, it gets updated to support the AMD processors. There are several applications for various functions, ranging from RGB lighting control, audio, system monitoring, overclocking, etc. We’ve captured several screenshots of the applications below. Here’s a look at Ai Suite 3, Armoury Crate, Sonic Studio, and the Realtek Audio application.

I call them "Irrelevant motherboards that people do not buy." :LOL:
Seriously though, these really are irrelevant to most people because no matter who is king at this level, things can be very different at the price points that most people are willing to pay.
Like, if I were in the market for an X670E board, I'd be looking at the ASRock X670E PG Lightning. ASRock isn't even represented here, probably because they don't think that there is a need for anything more expensive than a Taichi.
Maybe the test system needs to be looked at?
Why testing with RTX 3070, not RTX 4090?
Why MSI's uncore frequency is 1500MHz in CPU-Z, while other 2 boards running on 3000MHz?
PS: They are on different AGESA as well. CPU boosts differently on differently AGESA.
Who even buys this, rich kids from Saudi Arabia or something.

All of these mboards disappoint. I'm not going to go Intel, so I'll only compare and look for AMD mboards. MSI/Asus--far too expensive. Just ridiculous, frankly. You're right, the best board buy seems to be the Asroc you've mentioned. The GB board features almost the identical sound hardware that is featured on my x570 Master! They couldn't have improved it? Sad. $360 for my x570 was a great buy, considering the features it offers. The x670e Aorus Master costs $140 more than my x570 Master, but lacks several of the must-have features that made the Master so popular are not present in the x670e Master--including, incredibly, no backplate Clear CMOS button! And last, these are all E-ATX, which is going to require a new case purchase, on top of the rest of it. The 5800X3D is looking better all the time.
