Hyper M.2 socket that supports PCIe Gen4 x4 while M.2 socket is capable of running PCIe Gen3 x2 and SATA3 mode.

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.

Dr. MOS
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.

Premium 60A Power Choke
Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.

Hi-Density Power Connector
Reduces 23% power loss and decreases the connector’s temperature by 22 degrees Celsius.

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, it's able to support the latest DDR4 memory modules with most extreme memory performance!

RULE YOUR OWN LIGHTING WAY - POLYCHROME RGB
ASRock motherboards deliver stunning performance and superior aesthetics to rule your own colorful lighting way! ASRock offers a very comprehensive control to perform the built-in RGB LEDs or the connected LED strips, CPU fans, coolers, chassis and any RGB devices smoothly. Devices can be synchronized across the Polychrome RGB Sync-certified accessories as well.

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.

AMD SMART ACCESS MEMORY
Conventional PC systems processor can only access a fraction of graphics memory and limits system performance. With AMD Smart Access Memory, the data channel gets expanded to harness the full potential of GPU memory, removes the bottleneck and increase performance.
