Asrock 90-MXBJ40-A0UAYZ X670E Steel Legend Amd X670 90-MXBJ40-A0UAYZ

Server Grade Low Loss PCB
The server grade low loss PCB improves signal integrity, allowing motherboard to support PCIe 5.0 for both graphics card and M.2 SSD, it also improves memory OC potential to deliver the most extreme memory performance.

Optimized VRM Design
The 8 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency, ensures a reliable and long-lasting system while delivering ultimate performance without any compromise.

2 ounce copper inner layers that provide stable signal traces and power shapes! Delivering lower temperature and higher energy efficiency for overclocking.

DDR5 Memory with Protection Circuit
The reinforced DIMM slot is surfaced mounted onto the motherboard to give better physical strength as well as a more stable memory signal, with this superior revolutionary design, it is able to dramatically overclock DRAM module up to insane frequency.

Due to the unique electrical architecture of DDR5 DIMM, there’s a high risk of damaging the memory module if AC power isn’t disconnected properly during removal or installation. To prevent this, ASRock has implemented a trouble free protection circuit on every DDR5 motherboard, lowers the risk of damaging your memory module.

Blazing OC Tuner
The Blazing OC Tuner allows AM5 CPU to switch between OC mode and PBO(Precision Boost Overdrive) mode when the CPU current hits threshold. Anything above current threshold will engage manual OC mode; if below current threshold then will engage Precision Boost Overdrive mode. This idea is to combine overclocking on all cores and automatic boost on a single core to get the best performance out of your CPU. There is no need to enter BIOS to setup up, you can modify all the settings on time under OS.

Nahimic Audio
Whether you are using headphones, a headset, external or internal speakers, via USB, Wi-Fi, analog output or even HDMI, Nahimic Audio offers you the most engaging listening experience, vibrant and rich with details.

The Powerful algorithms to ensure the best noise-free conversation, giving a constant vocal level no matter the distance from your mic. The Nahimic audio engine dynamically clear the sound and remove interference noise and lower the voice variation. Result is a better comprehension and less fatigue.

Sound Tracker
The Sound Tracker is a visual indicator that points out the directions from which predominant sounds are coming. Each sound is properly positioned in 360° on a radar for a full immersion during the game.

Works on any devices!
Enjoy the vibrant and high-quality Surround Sound on all your favorite audio devices: Jack, USB, Bluetooth, HDMI, S/PDIF. Nahimic is compatible with all of your favorite audio tools and ensures the best sound with any of them. Nahimic measure and improve to optimize our technology and offer you the best experience.

ASRock Graphics Card Holder
Install your heavy graphics card on the holder; connect it to your motherboard and chassis with screws. Flexibly slide up and down to perfectly adjust the height required for your graphics card in place.

POLYCHROME RGB
In addition to the built-in RGB illumination, it also features onboard RGB headers and an addressable RGB header that allow motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.

High Speed M.2 Solution
The Blazing M.2 accommodates the latest PCI Express 5.0 standard to perform twice the bandwidth compared to previous generation, with a breathtaking 128GB/s transfer speed, it is ready to unleash the full potential of future ultrafast SSDs.

The extra large aluminum alloy M.2 heatsink effectively improves heat dissipation to keep those high speed M.2 SSDs as cool as possible, it is able to give better stability while maintaining top performance.

Tired of dropping screws or screws missing inside chassis?
The enhanced M.2 heatsink with anti-drop screw design that make sure installation process more easily.

Dragon 2.5 Gb/s LAN
The intelligent 2.5Gb/s LAN platform is built for maximum networking performance for the demanding requirements of home networking, content creators, online gamers and high-quality streaming media. Boost networking performance up to 2.5X the bandwidth compared to the standard gigabit Ethernet, you’ll enjoy the faster and uncompromised connectivity experience for gaming, file transfers and backups.

Wireless Networking
WiFi 6E technology has extended to the whole new 6GHz spectrum band, providing more WiFi capability and giving an even better and faster internet traffic. In addition to deliver higher speeds, the WiFi 6E also enhances the lower latency and supports service levels that are equivalent to 5G networks.

SMA cable is easy to loose, this is an unacceptable situation for every users. Now we fixed this issue with a little Key-E module cap.

Front USB 3.2 Gen2x2 Type-C
The latest USB 3.2 Gen2x2 Type-C delivers up to 20 Gbps data transfer rate which is 2x as fast as previous generation, providing a blazing fast data transfer interface with reversible USB Type-C design that fits the connector either way.

EZ Setting
Optical drive or driver DVD is no longer needed! ASRock motherboard already has its Ethernet driver prepacked in BIOS ROM, once finish installing the operation system, simply follow the instructions and allow ADI to download and install all necessary drivers automatically!
Step1: Install Auto Driver Installer
Step2: ADI will automatically download and install all necessary drivers.
Step3: Done!

Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and power supply, No CPU, RAM or other components required.

Unlike most so called pre-mounted I/O shield that is only decorated with fancy color schemes. We reserve more tolerance space and allow IO shield is adjustable when installing, thus fitting chassis perfectly without any mechanical issue.
