Product Description

Optimized VRM Design

SPS (Smart Power Stage)

Dr.MOS design features the latest SPS (Smart Power Stage) technology. It’s optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.

16+2+1 Power Phase Design

Featuring sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.

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.

8 Layer PCB

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.

2oz Copper PCB

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

Reinforced DIMM Slot

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.

DIY Friendly Design

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

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.

*The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.
*The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters.

High Speed M.2 Solution

PCIe Gen5 x4 for SSD

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.

XXL M.2 Heatsink

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.

Anti-Drop Screw

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

Wi-Fi 6E 802.11ax

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.

*The availability of Wi-Fi 6E (6GHz) may vary between different countries.

M.2 Key-E Module Cap

SMA cable is easy to lose, 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

Auto Driver Installer

BIOS ROM, once finish installing the operation system, simply follow the instructions and allow ADI to download and install all necessary drivers automatically!

  1. Install Auto Driver Installer
  2. ADI will automatically download and install all necessary drivers.
  3. Done!

BIOS Flashback

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.

Flexible Integrated IO Shield

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.
