Compact Intel B860 platform

This Mini ITX board uses the Intel B860 chipset with an LGA 1851 socket for Intel Core Ultra Series 2 processors. It provides two DDR5 slots supporting up to 128 GB and speeds up to 9333+(OC) via Intel XMP 3.0. A 10+1+1+1+1 phase design rated at 110 A handles VCore, GT and SA power delivery in a small form factor.

Gamers and small-form-factor builders

The single PCIe 5.0 x16 slot fits one full-size graphics card, while two M.2 sockets (one Gen5x4, one Gen4x4) and three SATA 6Gb/s ports cover fast storage. Builders needing multiple GPUs, legacy PCI slots or more than two memory modules should choose a larger ATX or micro-ATX board instead.

Straightforward Mini ITX install

Mount the board using standard Mini ITX standoffs, connect the 24-pin and 8-pin CPU power headers, then seat up to two DDR5 modules and one graphics card. The dense layout leaves little room around the CPU socket, so install the cooler before placing the board in the case. Verify M.2 screw positions for 2280 drives and check case clearance for the Thunderbolt 4 Type-C and HDMI ports on the rear I/O.

Perguntas sobre este artigo

Will this board fit in a Mini-ITX case and what CPU cooler clearance do I need?

The board uses the Mini-ITX form factor so it fits any Mini-ITX case. Cooler clearance depends on the case not the motherboard so check your case specifications.

Which memory kits are guaranteed to run at the advertised 9333 MT/s?

Only DDR5 CUDIMM kits rated for 9333 MT/s or higher with Intel XMP 3.0 profiles are validated. Standard DDR5 DIMMs may not reach that speed.

Can I run two NVMe drives at full PCIe 5.0 and 4.0 speeds simultaneously?

Yes. The CPU-linked M.2 slot runs PCIe 5.0 x4 and the chipset-linked slot runs PCIe 4.0 x4 so both operate at their rated bandwidth together.
