Optimized VRM Design
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.
9 Power Phase Design
Featuring sturdy components and completely smooth power delivery to the CPU, offering enhanced performance for gamers.
6 Layer PCB
The 6 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency for memory overclocking! Thus, it's able to support the latest memory modules with most extreme memory performance!
PCIe 5.0 + Surface-Mount Tech
Compares to conventional DIP style PCIe slot, the SMT type PCIe slot improves signal flow and maximize stability under high speed, a key breakthrough to fully support the lighting speed of the latest PCIe 5.0 standard.
The latest PCI Express 5.0 is capable to perform a breathtaking bandwidth of 128GBps, ready to unleash the full potential of future high end graphic cards.
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.
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
This motherboard is capable of accomadating multiple PCI Express 4.0 M.2 SSDs, which is capable of performing twice the speed compared to previous 3rd generation, giving a lightning fast data transferring experience.
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.
Base Frequency Boost (BFB) Technology
BFB Technology allow the use of increasing TDP to enjoy the base frequency boost with the hidden power of processors with users' non K series CPUs and ASRock’s selected 600 series motherboards
While ASRock BFB breathes life into non K series CPUs, the boost frequency currently still depends on the cooling system applied on your rig.
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.
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.
M.2 (KEY E) For WiFi
