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 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. BFB frequency performance results may vary between different CPUs and hardware configurations. 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. 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. M.2 (KEY E) For WiFi Besides the onboard LAN port, users may also choose 802.11ac wireless connections by M.2 (Key E) slot. *Wi-Fi module is not included.
