Nahimic Audio
Audio enhancement works with headphones, headsets and speakers over USB, Wi-Fi, analog or HDMI. A Sound Tracker radar shows where prominent sounds are coming from in 360°.
8 Power Phase Design
The components deliver smooth power to the CPU for better gaming performance.
2oz Copper PCB
Thicker copper inner layers keep signal traces and power stable, with lower operating temperatures and better energy efficiency. It supports DDR4 memory.
Polychrome RGB
Onboard RGB and addressable RGB headers connect to LED strips, CPU fans, coolers and cases. Polychrome RGB Sync-certified accessories can be synced for custom lighting. Addressable headers support up to 3A, 80 WS2812B LEDs and 2 m strips. RGB headers support 5050 RGB strips at up to 3A, 12V.
Wi-Fi 6E (802.11axe)
Speeds of up to 2.4 Gbps. It runs on 2.4 GHz and 5 GHz at the same time and has improved bidirectional MU-MIMO.
AMD Smart Access Memory
The CPU can use the full GPU memory, which reduces bottlenecks and raises performance.
Hyper M.2 (PCIe Gen4 x4)
Supports PCIe 4.0 M.2 SSDs, which are about twice as fast as the previous generation.
Reinforced Steel Slot (PCIe 4.0)
Extra anchor points and a stronger latch help keep the signal stable and hold heavy graphics cards securely.
Dual Graphics Outputs
An HDMI and DisplayPort combo gives you more display connection options.

Additional notes:
-
PCIe 4.0 x16 operation depends on the CPU: Gen4x16 with Vermeer and Matisse; Gen3x16 with Cezanne and Renoir; Gen3x8 with Picasso.
-
M2_1 operates at Gen4x4 with Vermeer and Matisse, and Gen3x4 with Cezanne, Renoir and Picasso.
-
NVMe SSDs are supported as boot disks. NVMe SSDs are not supported with AMD Athlon™ 3000G processors.
-
Wi-Fi 6E 6GHz functionality requires Windows 11 and a compatible 6GHz router. Availability depends on regional regulations and software updates.
-
For Ryzen Series APUs (Picasso, Cezanne and Renoir), ECC is only supported with PRO CPUs.
-
CPU_FAN1 supports up to 1A (12W). CHA_FAN1/WP, CHA_FAN2/WP and CHA_FAN4/WP support water cooler fans up to 2A (24W) and can automatically detect 3-pin or 4-pin fans.
