Intel B860 micro-ATX for Core Ultra Series 2

This LGA 1851 board targets builders who want a compact Intel platform with modern connectivity. It fits micro-ATX cases and supports the latest Core Ultra processors without requiring a full-size chassis. Buyers who need four memory slots or multiple x16 slots should look elsewhere.

DDR5 up to 9066 MT/s and single x16 Gen 5 slot

Two UDIMM slots accept up to 128 GB of DDR5, running at JEDEC 6400 MT/s or overclocked to 9066+ MT/s with one rank per channel. The sole PCIe 5.0 x16 slot connects directly to the CPU, while a second slot provides a single Gen 4 lane. Graphics output relies on the processor’s integrated engine via HDMI 2.1 or DisplayPort 1.4 at 4K 60 Hz.

Wi-Fi 7, EZ clips and extended heatsinks

Onboard Wi-Fi 7 and 5 GbE LAN deliver current wireless and wired speeds for professional and multimedia use. EZ M.2 Clip II, EZ PCIe Clip II and EZ Antenna simplify installation, while extended heatsinks with 7 W/mK pads and M.2 Shield Frozr manage thermals during sustained loads. Audio Boost provides studio-grade output for headphones or speakers.

Questions about this item

Will my existing DDR5 memory rated at 6400 MT/s work with the Intel Core Ultra Series 2 processor on this LGA 1851 board?

Yes, the board supports JEDEC speeds up to 6400 MT/s and Intel XMP 3.0, so 6400 MT/s modules run at their rated speed without manual tuning.

How can I confirm the PCIe 5.0 x16 slot is running at full Gen 5 speed after I install a graphics card?

Check the PCIe link speed in the BIOS hardware monitor or use a utility such as GPU-Z; it should report PCIe 5.0 x16 when a compatible card is seated in the primary slot.

Does the box include the Wi-Fi 7 antenna and M.2 mounting hardware, or do I need to buy them separately?

The EZ Antenna and EZ M.2 Clip II are bundled, so the Wi-Fi 7 antenna and M.2 mounting clip are included; no separate purchase is required for those items.
