Overview
The GIGABYTE B860 DS3H WIFI6E is an ATX motherboard designed for Intel Core Ultra desktop processors using the LGA1851 socket. Built around the Intel B860 chipset, it provides DDR5 memory support, PCIe 5.0 expansion, high-speed NVMe storage and integrated Wi-Fi 6E connectivity.
The motherboard combines a 4-DIMM memory architecture with dual M.2 storage connections, four SATA ports, 2.5GbE Ethernet and multiple USB interfaces. Its ATX layout provides expansion options for desktop gaming systems, productivity computers and general-purpose performance workstations.
Processor and Memory Support
The LGA1851 socket supports compatible Intel Core Ultra desktop processors. The Intel B860 chipset provides the platform for processor communication, memory management and peripheral connectivity.
Four DDR5 DIMM slots support up to 256GB of system memory using a dual-channel architecture. The motherboard supports Intel Extreme Memory Profile (XMP) memory modules, with supported memory speeds depending on the processor, BIOS and installed memory configuration.
Storage and Expansion
The B860 DS3H WIFI6E provides two M.2 connectors for NVMe solid-state drives. The primary M.2 connector supports PCIe 5.0 x4/x2 storage, while the secondary connector supports PCIe 4.0 x4/x2 SSDs.
Four SATA 6Gb/s connectors provide additional storage options for compatible hard drives and SATA SSDs. SATA RAID 0, 1, 5 and 10 configurations are supported.
For expansion cards, the motherboard includes one processor-connected PCIe 5.0 x16 slot and four chipset-connected PCIe 4.0 slots operating electrically at x1.
Wi-Fi 6E and Network Connectivity
Integrated Wi-Fi 6E provides wireless networking across the 2.4GHz, 5GHz and 6GHz frequency bands. The wireless module supports 160MHz channel operation and Bluetooth connectivity.
The wireless module varies by motherboard revision. GIGABYTE specifies Intel Wi-Fi 6E AX211 with Bluetooth 5.3 for revision 1.2 and Realtek RTL8852CE with Bluetooth 5.4 for revision 1.3.
Wired networking is provided by a Realtek 2.5GbE LAN controller supporting 2.5Gbps, 1Gbps and 100Mbps connection speeds.
Display and USB Connectivity
The rear I/O panel includes HDMI 2.1 and DisplayPort 2.1 outputs. HDMI supports resolutions up to 4096 x 2160 at 60Hz, while DisplayPort supports resolutions up to 3840 x 2160 at 144Hz. Actual display functionality depends on the installed processor.
USB connectivity includes a rear USB Type-C port with USB 3.2 Gen 2x2 support, a USB 3.2 Gen 2 Type-A port and four USB 2.0 ports. Internal headers provide additional USB Type-C, USB 3.2 Gen 1 and USB 2.0 connectivity for compatible case front-panel connections.
Power Delivery and Cooling
The motherboard provides an ATX power connection and an 8-pin CPU power connector. Dedicated CPU fan, CPU water-cooling pump and system fan headers support compatible cooling configurations.
Hardware monitoring includes voltage detection, temperature detection, fan-speed monitoring, water-cooling flow-rate detection and fan-failure warnings.

DC Supplies Product Note
The primary PCIe 5.0 x16 slot has an important allocation limitation: GIGABYTE specifies that it can support either a graphics card or an NVMe SSD, not both simultaneously through that slot. Plan the expansion configuration accordingly. Also check the motherboard PCB revision before selecting wireless drivers or Bluetooth specifications, as the wireless module differs between revisions.
