Socket LGA 1700 B660 board

The GIGABYTE B660M D2H DDR4 is a micro-ATX motherboard built around the Intel B660 chipset for 12th, 13th and 14th generation Core, Pentium Gold and Celeron processors. It provides a 6+2+1 phase hybrid digital VRM with a MOS heatsink, dual-channel DDR4 memory across two 288-pin slots, one PCI Express x16 slot and 7.1-channel audio.

Two-slot DDR4 builds only

This board suits builders who need a compact platform with 2.5 GbE LAN, dual PCIe 4.0 M.2 slots and RGB FUSION 2.0 lighting control. It is not suited for systems requiring four memory slots, higher base memory speeds than 2133 MHz or additional full-length expansion cards.

Dual PCIe 4.0 M.2

The pair of PCIe 4.0 x4 M.2 connectors is the specification that decides fit; it enables two high-speed NVMe drives directly from the CPU while the chipset handles remaining I/O. Q-Flash Plus allows BIOS updates without a CPU, memory or graphics card installed.

Questions about this item

What DDR4 memory kit do I need to populate the two 288-pin slots on this B660M D2H DDR4 board?

Install a dual-channel DDR4 kit up to 64 GB total; the board runs at 2133 MHz by default and supports overclocked speeds up to 5333 MHz with compatible modules.

Will my existing PCIe 3.0 NVMe drives run at full speed in the two M.2 slots?

Both M.2 slots are PCIe 4.0 x4; a PCIe 3.0 drive will operate at its rated PCIe 3.0 speeds without bottlenecking the slot.

How do I confirm the 2.5 GbE LAN and 7.1 audio are active after building the system?

Check Device Manager for a 2.5 GbE adapter and Sound control panel for 7.1-channel output; both appear once the chipset drivers are installed.
