The ASRock B860M Pro-A is a Micro ATX motherboard built for Intel Core Ultra Processors (Series 2) that prioritises memory overclocking performance and stability. It combines a 6-layer PCB design with DDR5 support up to 8666+ MHz and Intel XMP profile compatibility, making it suited to users who want reliable daily performance with room for memory tuning.

Why this product

6-layer PCB for stable overclocking

Dedicated power and signal layer design reduces temperature and improves energy efficiency when pushing DDR5 memory speeds. Pre-tested XMP/EXPO profiles let you apply performance gains without manual tuning.

DDR5 memory up to 8666+ MHz

Four 288-pin slots support up to 256GB total, with Intel XMP and AMD EXPO profile compatibility built in for plug-and-play overclocking on compatible modules.

PCIe 5.0 x16 slot

Future-ready expansion for next-generation graphics cards and high-speed storage devices.

Dual video outputs

HDMI and DisplayPort 1.4 connectors allow dual-monitor setups without additional adapters.

Best for

  • Memory overclocking enthusiasts
  • Small-form-factor builds
  • Dual-monitor workstations

Trade-offs

  • Budget builds without memory tuning plans. The Pro-A series focuses on overclocking features; entry-level boards offer the same core socket support at lower cost.
  • Multi-GPU or high-expansion setups. Single PCIe 5.0 x16 slot and Micro ATX layout limit expandability compared to full ATX or E-ATX boards.
  • Users upgrading from DDR4 systems. Only DDR5 is supported; existing DDR4 memory cannot be reused.
Pro-A series is designed for enhanced stability, durability, and efficiency, it offers reliable performance, user-friendly features and a streamlined aesthetic, making it ideal for daily use. The 6 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency for memory overclocking! Thus, it's able to support the latest memory modules with most extreme memory performance! Derived from the "built for stable and reliable" designing concept, ASRock does not compromise on any details. This motherboard is built with high quality materials, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance by enabling the pre-tested profiles. Make sure the memory modules are Intel® XMP/AMD EXPO™ capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all. * There are certain risks involved with memory overclocking and may affect your system's stability.
