## Long description

ASRock B860 Rock WiFi 7 is an ATX desktop motherboard built on the Intel B860 chipset for Intel Core Ultra (Series 2) processors using the LGA 1851 (Socket V1). It supports DDR5 memory across four DIMM slots up to 256 GB, offers PCIe Gen5 and Gen4 M.2 storage options, SATA III ports with RAID 0/1/5/10 support, integrated Realtek 2.5 Gb/s LAN and Wi‑Fi 7 (802.11be) wireless connectivity, plus front and rear USB Type‑C and Type‑A ports. The board incorporates an 8+1+1+1+1 power phase design with Dr.MOS, a 6‑layer PCB and aluminum heatsinks for stable power delivery and thermal management.
Advantages
The motherboard delivers stable power and thermal performance through a high-density power connector, Dr.MOS integrated power stages and an 8+1+1+1+1 power phase design, enabling reliable operation under heavy CPU load. Support for DDR5 XMP/EXPO profiles and a 6‑layer PCB improve memory overclocking potential and signal integrity. Modern I/O includes PCIe Gen5 M.2 for next‑generation SSDs, multiple PCIe slots, comprehensive USB Type‑C/Type‑A connectivity and onboard Wi‑Fi 7 for high throughput and low-latency networking. Built-in features such as reinforced PCIe slots, pre-installed I/O shield, fan headers with PWM/DC auto-detection and tool-less SSD installation simplify assembly and maintenance.
Suitable for
Gaming and high-performance desktop builds requiring modern CPU and DDR5 memory support
Content creation and video editing systems that need fast storage and 2.5 Gb/s network connectivity
Home or small office PCs needing reliable Wi‑Fi 7 wireless and multiple USB Type‑C ports
PC enthusiasts who plan to overclock memory or configure RAID arrays for storage performance

How to use
Install the ASRock B860 Rock WiFi 7 into a compatible ATX chassis and secure the pre‑installed I/O shield to the case cutout. Mount an LGA 1851 CPU and a compatible CPU cooler per the cooler manufacturer’s instructions, then insert up to four DDR5 memory modules in the recommended DIMM slots for dual‑channel operation. Connect the 24‑pin ATX and hi‑density CPU power connectors from your PSU. Populate storage devices using the M.2 slots or SATA III ports and connect front panel USB Type‑C if the case supports it. Attach system fans to the motherboard fan headers; the board will auto-detect PWM or DC fans and allow fan curve configuration via the firmware or ASRock utilities. After initial power-up, enter UEFI to verify memory XMP/EXPO profiles, storage recognition and to update BIOS if necessary.
Usage recommendations
For stable high-performance operation, use quality DDR5 modules certified for XMP or EXPO, ensure the PSU provides sufficient current to the hi-density CPU connector, and enable appropriate fan curves to maintain optimal temperatures. When installing high-speed PCIe Gen5 or Gen4 SSDs, consult SSD and chassis cooling guidance to avoid thermal throttling. Keep BIOS updated to the latest UEFI release for improved compatibility with Intel Core Ultra processors and memory profiles.
