GIGABYTE B860M H Micro ATX Motherboard
The GIGABYTE B860M H is a Micro ATX motherboard for Intel Core Ultra Series 2 processors using the LGA1851 socket and Intel B860 Express chipset. Its compact 24.4 × 21.5 cm format suits space-conscious desktop builds.
Two DDR5 DIMM sockets support dual-channel memory and up to 128 GB. Expansion and storage include a PCIe 5.0 x16 slot, two PCIe 4.0 M.2 slots and four SATA 6 Gb/s connectors, alongside Realtek 2.5GbE wired networking.
PCIe EZ-Latch assists graphics-card removal, while EZ-Debug diagnostic LEDs provide a practical troubleshooting aid. Check GIGABYTE’s processor support information before choosing a CPU; memory rates depend on the processor and memory configuration. The HDMI output also relies on the installed processor’s graphics capability.
