## Long description

The ASRock B860 Lightning WiFi is an ATX motherboard for Intel LGA 1851 (Socket V1) processors, built on the Intel B860 chipset and supporting DDR5 memory up to 256 GB across four DIMM slots. Designed for high-performance desktop and gaming systems, it integrates multiple M.2 and SATA III interfaces with RAID support, PCIe Gen5 readiness for next‑generation SSDs, Thunderbolt 4 Type‑C, Wi‑Fi 6E, and a 2.5 Gb/s LAN to provide balanced connectivity and storage options for demanding builds.
Advantages
The Lightning design emphasizes robust cooling and stable power delivery with large aluminum heatsinks, an XXL M.2 heatsink, a toolless M.2 heatsink quick‑release mechanism and a reinforced steel PCIe slot compatible with PCIe 5.0. Built with 2oz copper inner layers and a 14+1+1+1+1 phase power design with 80A Dr.MOS, the board supports reliable overclocking and sustained performance. Memory OC Shield reduces electromagnetic interference for improved memory overclocking stability, while onboard features such as Thunderbolt™ 4, Ultra USB Power, Polychrome RGB and SignalRGB support flexible connectivity and lighting customization.
Suitable for
High-performance gaming PCs
Content creation and streaming systems
Workstations requiring fast storage and network throughput
Enthusiast builds that use DDR5 memory overclocking and PCIe Gen5 SSDs

How to use
Install the motherboard into an ATX‑compatible chassis and secure it on standard standoffs. Mount an LGA 1851 CPU and install a compatible CPU cooler following the cooler manufacturer’s instructions. Populate DDR5 DIMMs in the recommended slots for dual‑channel operation and enable Intel XMP or AMD EXPO profiles in BIOS if the memory modules support them for simplified overclocking. Fit M.2 SSDs into the designated M.2 slots and use the toolless M.2 heatsink mechanism to secure and cool drives. Connect power from a compatible PSU, attach storage and peripherals, and use the rear USB/Thunderbolt ports, onboard Wi‑Fi or 2.5 Gb/s LAN for networking.
Usage recommendations
For stable overclocking and long‑term reliability, use high-quality cooling solutions and ensure good case airflow. Verify that DDR5 modules advertise Intel® XMP or AMD EXPO compatibility before enabling pretested overclocking profiles. When installing heavy graphics cards, make use of the reinforced steel PCIe slot and secure the card to the chassis to prevent mechanical strain.
