Product Overview
The GIGABYTE B860M EAGLE PLUS WIFI6E is a Micro-ATX motherboard built around the Intel B860 chipset and LGA1851 socket. Designed for Intel Core Ultra processors, it combines DDR5 memory support, PCIe 5.0 expansion, dual M.2 storage connectivity, Wi-Fi 6E and 2.5GbE wired networking.
Key Features
- Intel B860 Platform: LGA1851 socket support for Intel Core Ultra processors.
- DDR5 Memory: Four DIMM slots with dual-channel memory architecture and support for up to 256GB of system memory.
- PCIe 5.0 Expansion: A PCIe 5.0 x16 slot for a compatible graphics card or NVMe SSD, alongside PCIe 4.0 x1 expansion slots.
- Dual M.2 Storage: Two M.2 connectors, including one PCIe 5.0 and one PCIe 4.0 interface.
- Wi-Fi 6E: Wireless connectivity across 2.4GHz, 5GHz and 6GHz bands, with Bluetooth 5.3.
- 2.5GbE LAN: High-speed wired networking through the onboard Realtek 2.5GbE LAN controller.
- Display Connectivity: HDMI and two DisplayPort outputs for supported processor graphics.
Platform and Memory
The Intel B860 chipset and LGA1851 socket provide the platform for compatible Intel Core Ultra processors. Four DDR5 DIMM slots support dual-channel memory configurations, XMP memory modules and up to 256GB of system memory. Actual memory compatibility and operating speeds depend on the processor and installed memory configuration.
Storage and Expansion
The motherboard provides two M.2 connectors: one supporting PCIe 5.0 x4/x2 NVMe SSDs and another supporting PCIe 4.0 x4/x2 NVMe SSDs. Four SATA 6Gb/s connectors are also available for compatible storage drives.
The primary PCIe 5.0 x16 slot supports either a graphics card or an NVMe SSD, not both simultaneously. Additional PCIe 4.0 x1 slots provide expansion options for compatible cards.
Networking and Connectivity
Integrated Wi-Fi 6E supports 2.4GHz, 5GHz and 6GHz wireless bands, with Bluetooth 5.3. The specific wireless module varies by PCB revision: GIGABYTE documents Intel Wi-Fi 6E AX211 on certain revisions and Realtek Wi-Fi 6E RTL8852CE on others. Wired networking is provided by a Realtek 2.5GbE LAN controller.
Rear connectivity includes HDMI, two DisplayPort outputs, USB Type-A ports, USB 2.0 ports, an RJ-45 LAN port, audio jacks and wireless antenna connectors. The board also provides a front-panel USB Type-C connection.
Cooling and Build
The board features an 8+1+2 digital VRM design, a 6-layer PCB, M.2 thermal protection and GIGABYTE Smart Fan 6 support. Its Micro-ATX layout measures 24.4cm x 24.4cm.
