White ATX Platform for Intel Core Ultra 2

The ASRock B860 CHALLENGER WIFI WHITE is an ATX motherboard built around the Intel B860 chipset and LGA 1851 socket. It supports Intel Core Ultra Processors (Series 2) with Hybrid Technology, Turbo Boost Max Technology 3.0, Thermal Velocity Boost and Adaptive Boost Technology. The board includes integrated Intel UHD Graphics and Wi-Fi 7 connectivity.

Builders Committed to a Pure White Theme

This board suits enthusiasts assembling a white-themed system who want four DDR5 slots, a PCIe 5.0 x16 slot and a second PCIe 4.0 x16 slot. It is not for users needing ECC memory, buffered DIMMs or more than four SATA 6Gb/s ports. The single HDMI output also limits multi-monitor setups running from integrated graphics.

DDR5 8666 OC Ceiling Defines Memory Headroom

The maximum supported memory speed of DDR5 8666 (OC) via Intel XMP 3.0 across four 288-pin slots determines whether your kit will run at its rated frequency. With a 256GB capacity limit and dual-channel architecture, this specification is the primary filter for memory compatibility.

Questions about this item

What comes in the box and what must I buy separately?

The motherboard ships with I/O shield, SATA cables and manuals; you must purchase an LGA 1851 Intel Core Ultra processor, DDR5 memory modules, storage drives and a graphics card separately

Which memory speed version should I choose for this board?

The board supports DDR5 up to 8666 (OC) via Intel XMP 3.0 across four 288-pin slots with a 256 GB maximum

What does the 8666 memory speed figure mean once the system is built?

It is the peak overclocked transfer rate reachable with XMP 3.0 modules; actual speed depends on the memory kit and CPU memory controller quality
