GIGABYTE B860M K Intel Core Ultra (Series 2) LGA 1851 Intel motherboard

Socket and chipset

This GIGABYTE B860M K motherboard uses the LGA 1851 socket paired with the Intel B860 chipset. It is built for Intel Core Ultra 200 Series processors and fits a micro ATX chassis. The board targets builders who want a compact platform for modern CPUs without the cost of a larger form factor. Two DDR5 DIMM slots provide a straightforward memory upgrade path.

Who this suits

The board suits users assembling a mid-range system with a current-generation Intel processor and DDR5 memory. Enthusiasts needing four memory slots, more than two M.2 sockets, or extensive PCIe expansion should consider a full-size alternative. The 4+1+2 phase power design supports typical workloads but is not aimed at extreme overclocking. Builders wanting maximum connectivity or multi-GPU setups will need a different chipset.

Memory and storage headroom

Two DDR5 slots accept up to 128 GB total, with each slot supporting 64 GB modules. Speeds up to 8200 MT/s are possible when overclocking, while JEDEC standards reach 5600 MT/s. Two PCIe 4.0 x4 M.2 slots deliver fast storage for the operating system and primary applications. Additional drives must use the SATA ports, which are limited to the 6 Gb/s interface.
