ASUS B860M-E Intel B860 LGA1851 mATX Motherboard

This motherboard uses the Intel B860 chipset and the LGA1851 socket to support Intel Core Ultra Processors Series 2. It targets builders who want a compact mATX platform with modern connectivity and DDR5 memory support.

Installation ease and common issues

The board provides two DDR5 slots that support up to 128GB of memory and speeds up to 8800+ MT/s when overclocked with XMP or AEMP III profiles. A single CPU power connector is required, so check that your power supply includes the correct 8-pin EPS cable before you start.

Pre-purchase checks

Verify that your chosen processor appears on the ASUS CPU support list for this model, as Turbo Boost Max 3.0 depends on the specific chip. Ensure your case has an mATX mounting pattern and enough clearance for the rear USB 10Gbps Type-A and front USB 5Gbps Type-C headers. Builders who need more than two memory slots or additional full-length PCIe expansion cards should consider a larger form factor.

Questions about this item

How can I verify the board is running at the advertised 8800 MT/s memory speed after build?

Enter the BIOS and confirm the memory frequency reads 8800 MT/s or enable the XMP or AEMP III profile to apply the rated speed.

What comes in the box and what must I source separately for the LGA1851 socket?

The motherboard, I/O shield, SATA cables and documentation are included; a compatible Intel Core Ultra Series 2 processor, DDR5 memory, storage, power supply and chassis are purchased separately.

Which memory capacity should I choose for the dual-channel layout?

Install two DDR5 modules for dual-channel operation; the board supports up to 128 GB total across its two slots.
