Supermicro C741 Intel motherboard LGA-4677 ATX

Server-Class Xeon Platform

The Supermicro C741 is an ATX motherboard built around the Intel C741 chipset and the LGA-4677 socket. It targets system integrators and IT departments deploying 4th Gen Intel Xeon processors in rack or tower servers that require high memory capacity and PCIe 5.0 connectivity.

Straightforward Rack Integration

The board follows the standard ATX mounting pattern, so it fits common server chassis without custom brackets. Eight DIMM slots accept both RDIMM and DIMM modules, but population rules for maximum 2 TB capacity depend on the specific Xeon SKU; mis-matched ranks or speeds are the most common cause of POST failure. Three PCIe 5.0 x8 slots and two x16 slots leave little room for error when routing power cables in dense builds.

Verify Processor And Memory Before Purchase

Confirm the exact Xeon model you intend to use is validated for the C741 chipset and LGA-4677 socket, as not every 4th Gen part is supported. Ensure your DDR5 RDIMM or DIMM kits match the qualified vendor list for 2 TB total capacity across eight slots. Check that your chassis power distribution can deliver the required EPS connectors for the chosen CPU thermal design power.
