Moederbord ASRock B860M Pro RS WiFi — Intel B860, LGA 1851, micro ATX, DDR5, 4 DIMM, 3x M.2, 2.5Gb LAN, Wi‑Fi, Bluetooth

The ASRock B860M Pro RS WiFi is a micro ATX motherboard based on the Intel B860 chipset and designed for LGA 1851 (Socket V1) processors. It supports up to 256 GB of DDR5 memory across four DIMM slots, multiple M.2 and SATA III storage options including a PCIe Gen5-capable M.2 slot, integrated Wi‑Fi 6E, and a 2.5 Gb/s Dragon LAN port. The board uses a 10+1+1 power phase design with Dr. MOS and Hi‑Density Power Connectors, a 6‑layer PCB, aluminum heatsinks and reinforced PCIe steel slot for stable performance and thermal management.

Advantages

The motherboard delivers stable power delivery and thermal efficiency for daily computing and enthusiast workloads through a 10+1+1 power phase design with Dr. MOS, hi‑density CPU power connectors, and a 6‑layer PCB. It supports DDR5 XMP and AMD EXPO memory profiles for easier overclocking, offers a PCIe Gen5 Blazing M.2 slot for next‑generation NVMe SSDs, and includes USB 3.2 Gen2x2 Type‑C front/back connectivity. Integrated Wi‑Fi 6E and 2.5 Gb/s LAN provide faster network throughput, while Nahimic audio features and Polychrome RGB/SignalRGB compatibility add versatile multimedia and lighting control options.

How to use

Install the motherboard in a compatible micro ATX chassis and mount an LGA 1851 processor following the CPU and cooler manufacturer instructions. Populate up to four DDR5 memory modules into the DIMM slots and enable XMP or EXPO profiles in BIOS if using compatible memory for higher frequency operation. Connect storage devices to the M.2 and SATA III connectors as required; install the fastest NVMe SSD into the PCIe Gen5 M.2 slot for maximum performance. Attach power using the ATX and hi‑density CPU power connectors, connect front and rear USB Type‑C ports to corresponding headers or devices, and configure Wi‑Fi 6E and LAN settings in the operating system or BIOS. Update the motherboard BIOS and drivers from ASRock to ensure compatibility with Intel Core Ultra processors and the latest features.

Recommendations

For stable overclocking and sustained performance, use high‑quality power supplies with sufficient current on the CPU rail, ensure adequate case airflow to cool the aluminum heatsinks and M.2 SSD, and use memory modules certified for XMP or AMD EXPO. Keep BIOS and network/Wi‑Fi drivers up to date for best compatibility and security.
