Gigabyte B860M E GEN5 LGA1851 Micro-ATX DDR5 Motherboard
The Gigabyte B860M E GEN5 is a micro-ATX motherboard for Intel Core Ultra processors (Series 2), built around the B860 Express chipset. It brings PCIe Gen5 support and DDR5 memory to a compact form factor, suiting builders who need high performance without a full-size board.
Why this product
PCIe Gen5 x16 slot doubles bandwidth
The x16 expansion slot runs at PCIe 5.0, doubling data transfer rates to 32 GT/s per lane. This benefits high-end graphics cards, NVMe storage, and accelerators that demand the fastest connection.
DDR5 memory up to 128 GB
Two DIMM sockets support up to 128 GB of DDR5, with XMP Booster profiles for overclocked kits. The board handles memory speeds from 5600 to 8800 MT/s without manual tuning.
Compact micro-ATX form factor
Fits smaller cases and tighter builds while retaining full-sized feature set—24-pin ATX power, 8-pin CPU, dual M.2 slots, and four SATA ports.
Hybrid 4+1+2 phase VRM
Efficient power delivery for stable overclocking and sustained performance under load.
Dual display outputs via HDMI and DisplayPort
HDMI supports up to 4K60, DisplayPort up to 4K144. Useful for content creation, monitoring, or multi-display setups using integrated graphics.

Best for
- Builders seeking compact builds without compromising on PCIe Gen5 and DDR5 support.
- Content creators and professionals using integrated Intel graphics for dual or multi-monitor setups.
- Enthusiasts planning high-end GPU or accelerator upgrades with PCIe Gen5 bandwidth.
- Users who want DDR5 overclocking without manual BIOS tweaking via XMP Booster.
Trade-offs
- Owners of older Intel processors. Only Core Ultra Series 2 is supported; no backwards compatibility with 12th or 13th gen.
- DDR4 users. This board requires DDR5 memory; DDR4 slots are not present.
- Large form factor builds. Micro-ATX limits expansion compared to ATX or E-ATX boards—one GPU slot and limited internal headers.
- Workloads needing many SATA drives. Four SATA connectors support legacy storage, but NVMe is the preferred path on this platform.
The new GIGABYTE B860 motherboards provides the most efficient solution to enjoy boosted performance of PCIe Gen5 on the existing platform. PCIe 5.0 doubles the data transfer rate of PCIe 4.0 from 16 GT/s to 32 GT/s per lane. This substantial increase in bandwidth particularly benefits high-performance graphics cards, storage devices, and AI accelerators that demand faster data movement.
UD motherboards boost DDR5 memory performance and offer top-notch compatibility using various advanced methods. DDR5 XMP Booster feature offers ready-to-use settings derived from analysis of memory IC and PMIC vendor. This allows users to maximize DDR5 memory performance without the hassle of manual tweaking for overclocked DDR5 memory kits.
