GIGABYTE B860M D3HP motherboard LGA1851, micro-ATX, 4 × DDR5, 2 × PCIe x1, 1G LAN

The GIGABYTE B860M D3HP is a micro-ATX motherboard with the Intel B860 chipset and an LGA1851 socket for Intel Core Ultra (Series 1 and 2) processors. Four DDR5 slots, two PCIe 4.0 M.2 slots and two extra slots for add-in cards suit a home or office PC where a wired network is enough.

  • Socket and chipset: LGA1851, Intel B860, Intel Core Ultra (Series 1 and 2)
  • Form factor: micro-ATX, 244 × 244 mm
  • Memory: 4 × DDR5 DIMM, dual-channel, up to 256 GB, up to 9066 MHz
  • Storage: 2 × M.2 2280 PCIe 4.0, 4 × SATA III, RAID 0/1/5/10
  • Expansion slots: 1 × PCIe 5.0 x16, 2 × PCIe 3.0 x1
  • Ports: 1 Gbit/s LAN, HDMI 2.1, DisplayPort 2.1, 3 × USB 3.2 Gen 1, 3 × USB 2.0, PS/2

Description

Slots and interfaces for a work PC

Besides the PCIe 5.0 x16 graphics slot, the board has two PCIe 3.0 x1 slots for a sound card, network card or Wi-Fi card. There is a serial port header and a TPM connector on the board, and a PS/2 port on the rear panel for an older keyboard. The VRM is a hybrid 4+1+2+1 phase design with 50A stages, with heatsinks over the MOSFETs and chipset.

Who this motherboard is for

Anyone building a home or office PC who wants four memory slots and free expansion slots but can do without Wi-Fi and networking faster than gigabit. HDMI and DisplayPort run off the processor graphics, so a simple work PC does not necessarily need a graphics card.

Questions & answers

Which processors does this motherboard support?

The socket is LGA1851 and the manufacturer lists Intel Core Ultra (Series 1) and Intel Core Ultra (Series 2) processors as compatible. LGA1700 processors do not fit this board.

Does the board have Wi-Fi?

No, there is no Wi-Fi module on this board. Networking is 1 Gbit/s Ethernet (Realtek RTL8111H), and a Wi-Fi card can go into a PCIe x1 slot.

How many drives can I connect?

Two M.2 2280 PCIe 4.0 SSDs and four SATA III drives, up to six storage devices in total according to the manufacturer. RAID arrays are supported at levels 0, 1, 5 and 10.
