GIGABYTE B860M DS3H WIFI6E M-ATX Motherboard

The GIGABYTE B860M DS3H WiFi 6E is a Micro-ATX motherboard designed for Intel's LGA1851 platform, supporting Intel Core Ultra processors (Series 2) paired with the B860 chipset. It is aimed at builders who want a compact, feature-rich foundation without sacrificing connectivity or storage bandwidth. At the heart of its power delivery is a Hybrid 5+1+2 phase VRM solution, designed to provide stable and consistent power to Intel Core Ultra Series 2 CPUs. The board supports DDR5 memory in dual-channel configuration across four slots, with speeds validated up to 9066 MT/s through XMP profiles, and a maximum capacity of 256 GB. Both ECC Un-buffered and non-ECC Un-buffered DIMM modules are supported (operating in non-ECC mode). For storage, the B860M DS3H WiFi 6E features two M.2 Socket 3 slots — one of which operates at PCIe 5.0 x4 for next-generation NVMe SSDs — and both slots include a Thermal Guard heatsink to manage heat and sustain SSD performance under sustained workloads. Four SATA 6Gb/s ports expand storage options further. Expansion is handled by one CPU-direct PCIe 5.0 x16 slot for the primary graphics card or NVMe SSD, supplemented by three chipset-connected PCIe 4.0 x1 slots. The integrated Wi-Fi 6E (802.11ax) adapter supports the 6 GHz band with speeds reaching up to 2.4 Gbps, and Bluetooth 5.3 is included. A 2.5GbE LAN port rounds out the networking options. The WIFI EZ-Plug design simplifies antenna installation. The rear I/O panel includes one HDMI port, two DisplayPorts, one USB 3.2 Gen 2 Type-A port, two USB 3.2 Gen 1 ports, three USB 2.0/1.1 ports, one PS/2 keyboard/mouse port, and three audio jacks. Internal headers add a USB Type-C (USB 3.2 Gen 1), a USB 3.2 Gen 1 header, and two USB 2.0 headers. Addressable RGB is supported via three ARGB Gen2 headers and one standard RGB header. BIOS features include Q-Flash Plus for USB-based firmware updates without a CPU installed, Auto Scan for automatic BIOS file detection, and AI PerfDrive for customised BIOS preset profiles. A Clear CMOS jumper and reset jumper are included for quick troubleshooting.
