YINGHUA B660 D4 server motherboard

The YINGHUA B660 D4 is an M-ATX server motherboard built on the Intel B660 chipset for LGA 1700 processors. It targets system integrators and IT teams deploying compact 12th-generation Intel servers or workstations. Dual-channel DDR4 support up to 64 GB and multiple high-speed storage interfaces suit virtualisation hosts, storage nodes or edge appliances. The board delivers enterprise-oriented I/O in a 235 x 195 mm footprint.

Installation notes and common pitfalls

Mount the board using standard M-ATX standoffs; the 4-layer PCB aligns with typical chassis hole patterns. Connect the 24-pin ATX and 8-pin EPS power headers before seating the CPU and memory. A frequent oversight is populating only one DIMM slot, which halves memory bandwidth — use both slots for dual-channel operation. Ensure the M.2 22110 modules are secured with the correct standoff height to avoid shorting the PCIe 4.0 x4 traces.

Pre-order compatibility checks

Verify your chosen LGA 1700 processor is a supported 12th-generation Intel Core model; the supplier lists Intel Atom as the CPU type, so confirm the exact SKU before purchase. Check that your power supply provides both 24-pin and 8-pin EPS connectors for the 8-phase VRM. Confirm the chassis accommodates a 235 x 195 mm M-ATX board and offers clearance for the PCIe x16 and x4 expansion slots. Validate operating system requirements against Windows 10 or Windows 11 support.

Questions about this item

How can I confirm the board is running at DDR4 3200 MHz after installing memory?

Enter the AMI UEFI BIOS and verify the memory frequency reads 3200 MHz; the board supports dual-channel DDR4 up to 3200 MHz depending on the CPU and XMP profile

The package list shows only the motherboard — which cables or brackets must I source separately?

You will need to provide SATA data cables for the four SATA 3.0 ports, a CPU cooler for the LGA 1700 socket, and any M.2 mounting screws for the two 22110 NVME slots

Should I choose the PCI Express 4.0 / 5.0 x16 slot or the PCI Express 3.0 x4 slot for a single add-in card?

Use the PCI Express 4.0 / 5.0 x16 slot for maximum bandwidth; the PCI Express 3.0 x4 slot is intended for a second expansion card
