Moederbord GIGABYTE B860M E GEN5 LGA1851 voor Intel Core Ultra, DDR5 tot 8800 MHz (O.C.), 2x PCIe 4.0 M.2, 1GbE

The GIGABYTE B860M E GEN5 is a micro-ATX motherboard designed for Intel Core Ultra (Series 2) processors with an LGA1851 socket. It supports DDR5 memory up to 128 GB with overclocking potential up to 8800 MHz (O.C.), and offers PCIe Gen5-ready platform features alongside two PCIe 4.0 x4 M.2 slots, SATA III with RAID 0/1/5/10 support, and integrated Gigabit Ethernet. The board targets gaming, content creation and workstation use while maintaining a compact micro-ATX form factor suitable for smaller builds.

Advantages

This motherboard combines modern connectivity and performance-oriented design: DDR5 memory support with high overclocking headroom, a hybrid 4+1+2 phase VRM for stable power delivery, and PCIe Gen5-capable expansion. Dual PCIe 4.0 M.2 connectors and SATA III RAID support enable flexible storage configurations, while integrated Gigabit Ethernet and multiple display outputs provide straightforward networking and video options. User-focused BIOS features and EZ-Latch PCIe slot design simplify setup and component changes.

Suitable for

• Compact gaming systems based on Intel Core Ultra (Series 2)
• Content creation and video editing workstations with fast NVMe storage
• Office and productivity PCs requiring reliable Gigabit Ethernet connectivity
• Small-form-factor builds that need modern I/O and DDR5 support

When it may not be suitable

This micro-ATX board may not be the best choice for users who need full-size ATX feature sets such as a large number of PCIe slots or extreme multi-GPU setups. It also does not provide built-in 2.5GbE or faster onboard networking, so users who require higher-than-gigabit LAN speeds will need an add-in card or external solution.

How to use

Install the CPU into the LGA1851 socket following Intel and GIGABYTE mounting instructions, populate up to two DDR5 DIMMs in the recommended slots, and secure the board into a compatible micro-ATX case. Connect storage devices to the M.2 slots or SATA ports and configure RAID in the UEFI BIOS if required. Use the BIOS or GIGABYTE software tools for fan control, multi-theme UI and to apply AI Perfdrive presets for optimized BIOS profiles. Ensure proper cooling and power connections to the VRM area when planning higher memory overclocks.

What to consider before purchase

• Ensure your CPU is an Intel Core Ultra (Series 2) compatible with LGA1851.
• Choose DDR5 memory kits that are supported and consider cooling if you plan to overclock to high frequencies.
• Verify case compatibility with micro-ATX form factor and available clearance for expansion cards and coolers.
• Plan network needs: onboard Gigabit Ethernet may be insufficient for users needing faster LAN throughput.

Recommendations

For balanced performance in gaming and content creation, use high-quality DDR5 memory modules rated for overclocking, install NVMe SSDs in the PCIe 4.0 M.2 slots for the OS and active projects, and keep VRM cooling adequate when pushing memory or CPU performance.
