Overview
The GIGABYTE B860M H DDR5 is a Micro ATX motherboard built on the Intel B860 Express Chipset, designed to support Intel Core Ultra processors (Series 2). Measuring 24.4 cm x 21.5 cm, it fits compact mid-tower and Micro ATX cases while delivering a capable feature set for productivity and gaming system builds. At its core, the board uses a Hybrid 4+1+2 phase VRM configuration to deliver stable power to supported Intel processors. Memory support is handled by two DDR5 DIMM slots in a dual-channel configuration, accommodating up to 128 GB of system memory (up to 64 GB per single DIMM). Native speeds of 5600 MT/s and 6400 MT/s are supported, with overclocked profiles reaching up to 8800 MT/s via XMP. The board also supports ECC Unbuffered DIMMs operating in non-ECC mode, and XMP 3.0 memory profiles for simplified memory tuning through GIGABYTE's DDR5 XMP Booster feature. Expansion is handled by a PCIe 5.0 x16 slot from the CPU for a discrete graphics card or NVMe SSD, plus a chipset-connected PCIe 4.0 x1 slot. Storage options include two M.2 connectors (PCIe 4.0 x4, type 2280) and four SATA 6Gb/s ports, with support for RAID 0, 1, 5, and 10 across SATA devices. Networking is provided by a Realtek 2.5GbE LAN chip supporting speeds of 2.5 Gbps, 1 Gbps, and 100 Mbps. The back panel includes an HDMI 2.1 output capable of 4096x2160 at 60 Hz (subject to CPU support), four USB 3.2 Gen 1 ports, two USB 2.0 ports, a PS/2 port, and three audio jacks. Audio is managed by a Realtek High Definition Audio CODEC supporting up to 7.1-channel output with S/PDIF Out. Board management features include GIGABYTE's AI Perfdrive for customised BIOS profiles, the EZ-Latch PCIe quick-release mechanism, Q-Flash BIOS update utility, EZ Debug Zone LEDs, and a DRAM slot indicator LED. Two addressable RGB Gen 2 headers are included for LED strip connectivity. The AMI UEFI BIOS supports PnP 1.0a, DMI 2.7, ACPI 5.0, and SM BIOS 2.7. Hardware monitoring covers voltage, temperature, fan speed, and water cooling flow rate. The board carries a 3-year manufacturer warranty and supports Windows 10 and Windows 11 64-bit operating systems.
