Product information

Description

Optimized for stability, durability and efficiency, this ASRock motherboard combines reliable performance, user-friendly features and a streamlined design for daily computing tasks. It supports high-current power delivery, advanced memory overclocking profiles and the latest PCIe 5.0 storage devices, making it suitable for demanding home and gaming systems.

Advantages

The Hi-Density Power Connector and 14+2+1 power phase design provide stable and sustained power for CPU overclocking while reducing thermal stress. Integrated Dr.MOS components and an 8-layer PCB improve power efficiency and thermal performance for both CPU and memory. Native DDR5 XMP/EXPO support enables easy memory overclocking via pre-tested profiles. PCIe Gen5 Blazing M.2 and a reinforced PCIe 5.0 steel slot deliver future-proof high-speed storage and secure GPU mounting. Additional features include an optimized aluminum heatsink, 2.5 Gb/s Dragon LAN for faster networking and Nahimic audio enhancements for clear communication and immersive sound.

Key specifications

  • Power design: Hi-Density Power Connector; 14+2+1 power phase
  • Power components: Dr.MOS integrated power stage
  • PCB layers: 8-layer PCB for stable signals and thermal control
  • Memory: DDR5 with Intel® XMP and AMD EXPO™ support
  • Storage: PCIe Gen5 Blazing M.2 (up to 128 Gb/s)
  • Expansion slot: Reinforced steel PCIe slot (PCIe 5.0 compatible)
  • Cooling: Optimized aluminum heatsink design
  • Networking: Dragon 2.5 Gb/s LAN
  • Audio: Nahimic audio engine with noise suppression, echo cancellation and voice stabilizer
  • RGB: Polychrome RGB and addressable RGB headers; SignalRGB support

How to use

Install the motherboard into a compatible case, secure it to standoffs and connect the Hi-Density CPU power connector(s) from a PSU rated to handle required current for overclocking. Install DDR5 memory modules that support Intel XMP or AMD EXPO and enable the desired pre-tested profile in firmware for stable overclocking. Fit PCIe Gen5 M.2 SSDs into the Blazing M.2 slot and attach graphics cards to the reinforced steel PCIe slot, ensuring latches and anchor points are engaged. Connect LAN, audio and RGB devices to their respective headers and configure Nahimic audio settings and Polychrome/SignalRGB lighting software as needed. Verify cooling is adequate and monitor temperatures during initial operation and when overclocking.

Recommendations

Use a high-quality power supply with sufficient current capacity when overclocking, ensure memory modules explicitly support XMP/EXPO profiles, and maintain good case airflow to benefit from the 8-layer PCB and aluminum heatsinks. Update firmware and drivers to the latest versions for best stability and compatibility.
