## Long description

ASRock B860 Challenger WiFi is an ATX motherboard based on the Intel B860 chipset with LGA 1851 (Socket V1) compatible with Intel Core Ultra (Series 2) processors. The board supports DDR5 memory across four DIMM slots for up to 256 GB, offers PCIe 5.0 and PCIe 4.0 M.2 storage options, SATA III ports with RAID 0/1/5/10 support, and integrated networking including 2.5 Gb Ethernet and Wi‑Fi 7 (802.11be). Designed for desktop systems where a balance of connectivity, expandability and thermal management is needed, this motherboard includes features such as advanced power delivery, M.2 toolless installation, multiple fan headers and onboard audio enhancements to support demanding workloads and gaming setups.
Advantages
The motherboard provides modern connectivity with PCIe Gen5 M.2 support and Wi‑Fi 7 for higher wireless throughput and lower latency. A robust 10+1+1 power phase design with Dr.MOS and hi-density power connectors ensures stable CPU power delivery suitable for sustained performance. Integrated cooling features include aluminum heatsinks and auto-detect fan headers for PWM/DC fans with Fan-Tastic Tuning to optimize fan curves. Built-in 2.5 Gb Ethernet and Lightning Gaming Ports reduce network and input latency, while onboard audio processing improves voice clarity and spatial sound for content and gaming use.

How to use
Install the ASRock B860 Challenger WiFi into a compatible ATX chassis following standard anti-static precautions. Mount an LGA 1851 CPU that is supported by the motherboard, populate up to four DDR5 DIMMs according to the manual’s recommended slot order, and connect PSU power using the hi-density CPU and 24‑pin ATX connectors. Fit NVMe SSDs into the M.2 slots and secure the toolless M.2 heatsink if required. Connect chassis fans to the PWM/DC headers and configure fan curves via the provided fan control utility. Use BIOS/UEFI to enable XMP/EXPO memory profiles, adjust power settings, and set storage RAID when needed. Install the latest drivers for network and audio components for optimal performance.
Usage recommendations
For stable high-load operation, ensure adequate case airflow and attach the aluminum heatsinks to critical components. When using overclocking or high-current CPUs, use a power supply with sufficient amperage on the 12V rail and enable the pretested DDR5 memory profiles (XMP/EXPO) only with compatible modules. Keep the UEFI BIOS and device drivers up to date to maintain compatibility with newer processors, SSDs and networking features such as Wi‑Fi 7.
