Socket LGA 1851 Platform

The GIGABYTE B860 GAMING X WIFI6E is an ATX motherboard built for Intel Core Ultra Series 2 processors. It uses the B860 chipset and provides four DDR5 memory slots supporting up to 256 GB in dual-channel mode. The board targets builders who want a modern LGA 1851 foundation with integrated WIFI6E and 2.5 GbE networking.

PCIe 5.0 x16 and Three M.2 Slots

The primary PCI Express x16 slot runs at PCIe 5.0 x16 and accepts either a graphics card or an NVMe SSD. Two additional chipset slots operate at PCIe 4.0 x1. Storage expansion includes one CPU-attached M.2 connector with PCIe 5.0 x4 support and two chipset M.2 connectors with PCIe 4.0 x4 support. Users needing multiple PCIe 5.0 x16 graphics slots should consider a different chipset.

12+1+2+1 Phase 50A VRM

The power delivery uses a 12+1+2+1 phase design with 50 A PPAK stages. This configuration is the key specification for determining whether the board can sustain the thermal and current demands of your chosen Core Ultra processor under load.

Questions about this item

Will my existing CPU cooler fit this LGA 1851 socket?

Only coolers that list LGA 1851 support will mount correctly; older LGA sockets use a different hole pattern.

Can I run four DDR5 sticks at the rated 256 GB maximum?

Yes, the four 288-pin slots support up to 256 GB in dual-channel mode with non-ECC or ECC unbuffered DIMMs.

Which M.2 slot should I use for a PCIe 5.0 NVMe drive?

The CPU-linked M2A_CPU slot is the only one wired for PCIe 5.0 x4; the other two chipset slots run at PCIe 4.0 x4.
