Micro-ATX Server Motherboard with Dual 10GbE

The ASRock Rack W680D4U-2L2T/G5 is a Micro-ATX server motherboard built on the Intel W680 chipset. It supports a single LGA 1700 socket for 12th, 13th and 14th Gen Intel Core series processors with a thermal design power of 125W. Four DDR5 DIMM slots provide ECC and non-ECC UDIMM support. Dual 10GbE LAN ports are driven by an Intel X710 controller alongside two 1GbE ports from an Intel i210 controller.

Expansion Layout and Lane Sharing

This board suits builders who need a compact server platform with high-speed networking and flexible storage connectivity. It offers one PCIe 5.0 x16 slot, one PCIe 4.0 x4 slot and one PCIe 3.0 x1 slot. Three OCuLink connectors deliver PCIe 4.0 x4 links and one additional OCuLink can switch to four SATA 6Gb/s ports. Builders who require more than one PCIe 5.0 x16 slot or more than four DDR5 DIMM slots should look at larger form-factor server boards.

DDR5 Memory Speed Limits

The single specification that decides fit is the DDR5 memory speed ceiling tied to population. With one DIMM per channel the board runs at 5600MT/s; filling both channels with single-rank modules drops the limit to 4000MT/s and with dual-rank modules to 3600MT/s. Each slot accepts up to 32GB. Buyers planning to populate all four slots with high-capacity dual-rank DIMMs must accept the lower 3600MT/s operating speed.

Questions about this item

What are the Micro-ATX dimensions and CPU socket type for the W680D4U-2L2T/G5?

The board measures 9.6" x 9.6" and uses an LGA 1700 socket for 12th, 13th and 14th Gen Intel Core processors with up to 125W TDP.

How is the OCuLink4 port affected when installing a card in SLOT7?

OCuLink4 shares lanes with SLOT7; populating SLOT7 with a PCIe 4.0 x4 device disables the OCuLink4 connector, so plan your storage or expansion layout before mounting the board.

Which memory speeds are supported with one or two DIMMs per channel?

DDR5 runs at 5600 MT/s with one DIMM per channel, 4000 MT/s with two single-rank DIMMs per channel, and 3600 MT/s with two dual-rank DIMMs per channel; maximum capacity is 32 GB per DIMM.
