LGA 1851 Intel B860 Micro ATX motherboard

The ASRock B860M Challenger WiFi is built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It uses the Intel B860 chipset and provides onboard Intel Xe LPG graphics. The board supports up to 256 GB of DDR5 5600 memory across four 288 pin slots running in dual channel mode with Intel XMP 3.0 profiles. It is aimed at builders who want a compact platform for modern Intel CPUs.

Straightforward installation

The board follows the Micro ATX form factor so it fits most cases designed for that size. CPU power uses a 10+1+1+1+1 phase Dr.MOS design that connects with regular EPS cables. Four DDR5 slots are spaced normally and the single PCI Express 5.0 x16 slot sits in the top position. Common issues include forgetting to seat the 288 pin DDR5 modules fully until the latches click and overlooking the extra 4 pin CPU power connector needed for full phase operation.

Suits compact Core Ultra builds needing 2.5 Gbps

This motherboard fits users building a smaller system with an Intel Core Ultra Series 2 processor who need 2.5 Gbps wired networking and wireless connectivity. The four SATA 6Gb/s ports and three M.2 sockets cover typical storage needs. Builders requiring more than one full length PCIe 5.0 x16 slot or specialised server features such as ECC memory should look at larger chipset options instead.

Questions about this item

How can I confirm the board is working after the first boot?

The system should POST and display the ASRock splash screen, then enter the BIOS where the 10+1+1+1+1 Dr.MOS power phases and installed DDR5 memory are reported correctly.

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

The motherboard, I/O shield, SATA cables, M.2 screws and quick-install guide are included; you must buy an LGA 1851 Intel Core Ultra Series 2 processor, DDR5 modules, storage drives and a graphics card separately.

Which DDR5 speed should I choose for this board?

The board runs DDR5 at 5600 MT/s by default and supports Intel XMP 3.0 profiles up to 8666+ MT/s when overclocked, so select a kit rated for your desired speed within that range.
