Emolevy ASROCK B860M Pro RS — Intel B860, LGA 1851, micro ATX, DDR5, 4× DIMM, 2.5Gb LAN, 1×PCIe5 x16

Modern and futuristic, the Race Sport (RS) Edition is an evolution of the PRO series motherboard, designed for stable daily computing and advanced performance. It balances durability, efficiency and user-friendly features while offering a streamlined appearance. Built with high-quality components, the board supports current-generation memory and storage standards to meet demands from general use to gaming and content creation.

Advantages

The motherboard delivers stable power delivery through a Hi-Density power connector and a 10+1+1 power phase design with Dr. MOS for improved current handling and thermal performance. A 6-layer PCB enhances signal integrity and energy efficiency, enabling reliable memory overclocking with DDR5 XMP and AMD EXPO support. Storage performance is future-ready with a PCIe Gen5 Blazing M.2 slot. Additional practical features include an M.2 bottom heatsink, aluminum heatsinks for cooling, integrated 2.5 Gb/s LAN, onboard and addressable RGB headers with Polychrome RGB and SignalRGB support, dual video outputs (HDMI + DisplayPort), and a reinforced steel PCIe slot for secure GPU installation.

How to use

Install the motherboard into a compatible ATX chassis, connect the Hi-Density CPU and main ATX power connectors, and fit DDR5 memory modules that support XMP or EXPO profiles if overclocking is intended. Mount the M.2 SSD into the Blazing M.2 slot and ensure the M.2 bottom heatsink is properly seated to aid heat dissipation. Attach GPU(s) to the reinforced PCIe slot and connect display cables to the HDMI or DisplayPort outputs. Install drivers and firmware updates from the manufacturer to enable LAN, RGB control (Polychrome/SignalRGB) and other platform features.

Recommendations

For best stability and performance, use certified XMP/EXPO DDR5 modules, ensure adequate case airflow to complement the aluminum heatsinks, and keep BIOS and drivers up to date. When overclocking, monitor temperatures and verify power connections, especially the Hi-Density CPU connector, to maintain safe operation.
