ASRock Rack W680 WS server motherboard LGA 1700 DDR5 4400 192GB ECC 4x 1GbE

Intel W680 workstation board for DDR5 ECC builds

The ASRock Rack W680 WS is an ATX server motherboard that accepts 12th, 13th and 14th Gen Intel Core processors in an LGA 1700 socket. Four 288‑pin DDR5 slots run at 4400 MT/s and support up to 192 GB of ECC or non‑ECC UDIMM. The Intel W680 chipset provides the platform foundation for professional workloads.

Expansion layout and connectivity trade‑offs

One PCIe 5.0 x16 slot and one PCIe 5.0 x8 slot share CPU lanes, so the x16 slot drops to x8 when the x8 slot is populated. Two additional PCIe 4.0 x4 slots connect through the CPU and PCH respectively. Dual M.2 M‑key sockets accept 2280, 2260, 2242 and 2230 drives at PCIe 4.0 x4, while five SATA 6.0 Gb/s ports handle traditional storage. Four Intel I210 1 GbE ports, COM, VGA, HDMI, DisplayPort and two USB 3.2 Gen 1 Type‑A ports complete the rear I/O.

Sustained operation with 125 W TDP ceiling

The board is rated for processors with a 125 W thermal design power, setting the cooling target for continuous load. Memory runs at the specified 4400 MT/s without overclock headroom, and ECC correction operates continuously to maintain data integrity. Four 1 GbE links provide steady network throughput without the burst variability of higher‑speed interfaces. The shared PCIe lane arrangement means sustained GPU and add‑in card bandwidth divides predictably when both primary slots are occupied.
