Product information

Description

Optimized for stability, durability and efficiency, this ASRock motherboard combines reliable performance, user-friendly features and a streamlined style for daily computing tasks. It includes an 8+2+1 power phase VRM, Dr.MOS integrated power stages, Hi-Density power connectors and a 6-layer PCB to support stable CPU and memory overclocking. The board also provides PCIe Gen5 M.2 support, multiple high-speed M.2 slots, reinforced PCIe slot, onboard Wi-Fi 6E, 2.5 Gb/s LAN and versatile audio and RGB options for a balanced desktop build.

Advantages

The robust VRM design with 8+2+1 phases and Dr.MOS ensures smooth and efficient power delivery to the CPU, improving thermal performance and stability during heavy loads or overclocking. Hi-Density power connectors and a 6-layer PCB enhance current handling and signal integrity, enabling higher memory and CPU performance. High-speed storage options include PCIe Gen5 M.2 and Hyper M.2 Gen4 x4 for fast SSD throughput. Integrated Wi‑Fi 6E and 2.5 Gb/s Dragon LAN provide faster and lower-latency network connections. The board also features intelligent cooling with aluminum heatsinks, PWM/DC fan support and ASRock’s Fan‑Tastic tuning for precise fan control. Nahimic audio, Polychrome RGB and SignalRGB support add flexible multimedia and lighting customization, while dual graphics outputs and a reinforced steel PCIe slot simplify GPU installation and longevity.

Key specifications

  • VRM: 8+2+1 power phase design with Dr.MOS integrated power stages
  • Power connectors: Hi‑Density CPU and ATX power connectors for improved current handling
  • PCB: 6‑layer PCB for stable signals and better thermal efficiency
  • Memory: DDR5 support with Intel XMP and AMD EXPO profile compatibility
  • Storage: PCIe Gen5 Blazing M.2 and Hyper M.2 Gen4 x4 M.2 slots
  • Cooling: Aluminum heatsinks, M.2 bottom heatsink, PWM/DC fan headers and Fan‑Tastic tuning
  • Networking: Wi‑Fi 6E (802.11ax 6GHz) and Dragon 2.5 Gb/s LAN
  • Audio: Nahimic audio suite with noise suppression, echo cancellation and Sound Tracker
  • RGB: Onboard RGB and addressable RGB headers, Polychrome RGB and SignalRGB support
  • Expansion: Reinforced steel PCIe slot (PCIe 5.0 ready), HDMI + DisplayPort outputs
  • BIOS/UX: EZ BIOS flashback (USB + power), preinstalled LAN driver and preinstalled I/O shield

How to use

Install the motherboard into a compatible ATX chassis, connect the Hi‑Density CPU and ATX power connectors, and mount CPU, cooler, memory and storage according to the manufacturer’s instructions. Enable DDR5 XMP or AMD EXPO profiles in BIOS to apply pre‑tested memory overclock settings. For NVMe storage, install PCIe Gen5 or Gen4 M.2 SSDs into the designated M.2 slots and secure the M.2 heatsinks to improve thermal performance. Use the BIOS EZ Flash feature to update firmware via USB if needed. Configure fan curves through ASRock A‑Tuning Fan‑Tastic Tuning and select PWM or DC mode as detected by the fan headers. Connect network devices via onboard Wi‑Fi 6E or the 2.5 Gb/s LAN port and set up audio preferences with Nahimic software where applicable.

Recommendations

Use compatible DDR5 modules that support Intel XMP or AMD EXPO to achieve stable memory overclocking. When installing high-power CPUs or performing heavy overclocking, use a high-quality power supply and ensure good case airflow; secure the reinforced PCIe slot and use the M.2 heatsinks to maintain SSD performance.
