Gigabyte B860M Eagle V2 Intel LGA1851 Micro-ATX Motherboard
The Gigabyte B860M Eagle V2 is a micro-ATX motherboard built for Intel Core Ultra processors, balancing compact form factor with robust power delivery and thermal management. It suits builders who need DDR5 performance and PCIe 5.0 in a smaller footprint without compromising on cooling or connectivity. Steady power distribution and multi-layer thermal design keep systems stable during sustained workloads.
Why this product
PCIe 5.0 and DDR5 support
One PCIe 5.0 x16 slot and one PCIe 5.0 M.2 connector enable the fastest storage and graphics today. DDR5 memory up to 9066 MT/s (overclocked) maximizes bandwidth for CPU-intensive tasks.
Advanced thermal design
Full-metal heatsinks with up to 4× traditional cooler surface area, 5 W/mK thermal pads, and M.2 Thermal Guard prevent throttling under load.
Solid Pin connectors
UD Solid Pin design on the 8-pin CPU and 24-pin ATX connectors improves conductivity and reduces wear from repeated use.
Compact micro-ATX layout
24.4 × 22.5 cm form factor fits smaller cases while retaining dual M.2, dual fan headers, and full I/O without compromise.
8-channel HD audio with isolation
Analog audio components are isolated from PCB noise sources, and high-end capacitors reduce distortion for cleaner sound.

- EAN4719331869656
- Works with Intel Core Ultra processors in LGA1851 socket. Check GIGABYTE's CPU support list for your specific chip model.
- Accepts DDR5 DIMM modules up to 128 GB total (two slots, 64 GB max per slot) with speeds from 5600 to 9066 MT/s.
- Supports 2.5 GbE Ethernet and features HDMI and DisplayPort output; actual display support depends on CPU integrated graphics.
- Runs Windows 11 64-bit and Windows 10 64-bit. NPU driver and Intel 800 Platform Performance Package require Windows 11.
- Micro-ATX size means it fits most cases, but very compact builds may face tight clearance near the rear I/O or power connectors.
Best for
- Small-form-factor builds with high performance needs
- Builders prioritising DDR5 speed and PCIe 5.0 storage in a compact board
- Systems requiring robust cooling without bulky external radiators
- Enthusiasts using XMP 3.0 memory profiles or custom SPD tuning
Trade-offs
- Extreme multi-GPU setups — only one PCIe x16 slot limits SLI/Crossfire configurations.
- Builders needing many SATA drives — only 4 SATA connectors compared to ATX boards with 6 or more.
- Server or workstation ECC-only deployments — ECC support exists but the board is not certified for mission-critical error correction.
- Analog audio perfectionists — 8-channel HD audio is solid but not high-end audiophile grade despite the isolation and capacitor upgrades.
EAGLE motherboards boost DDR5 memory performance and offer top-notch compatibility using various advanced methods.
Unlock the full power of your multi-core CPU for unmatched performance. Optimized for integrated GPU performance and memory management within the CPU. Deliver reliable power to your CPU-connected PCIe lanes for uninterrupted performance.
EAGLE motherboards come with advanced full-metal thermal design and durable heatsinks to keep your system cool and efficient.
