## Long description

The ASRock B860I Lightning WiFi is a Mini ITX motherboard built on the Intel B860 chipset with an LGA 1851 (Socket V1) for modern Intel processors. It supports up to 128 GB of DDR5 memory across two DIMM slots, integrates Intel Iris Xe graphics, and provides high-speed storage options including PCIe Gen5 M.2 and SATA III. Connectivity features include 2.5 Gb/s Ethernet, Wi‑Fi 6E (802.11ax) and Bluetooth 5.3, as well as Thunderbolt 4 Type-C for fast data and display connectivity. The Lightning series design emphasizes robust power delivery, advanced cooling with composite VRM heatsink and aluminum heatsinks, and reinforced PCIe slots for heavy graphics cards.
Advantages
The motherboard combines a compact Mini ITX form factor with enthusiast-grade features such as a 10-layer PCB for improved signal stability and power efficiency, DDR5 XMP/EXPO support for straightforward memory overclocking, and ASRock’s patented Memory OC Shield to reduce electromagnetic interference during high-frequency operation. PCIe Gen5 Blazing M.2 support enables future-ready ultra-fast SSDs, while integrated Wi‑Fi 6E and Phantom Gaming 2.5 Gb/s LAN deliver low-latency and high-bandwidth networking. Thermal solutions like the composite VRM heatsink with fan and aluminum heatsinks enhance sustained performance under load.
