Single-socket LGA 4677 server board

The ASRock Rack SPC741D8-2L2T/BCM is a CEB form-factor motherboard built for one 4th or 5th Gen Intel Xeon Scalable processor up to 350 W TDP. It uses the Intel C741 chipset and provides eight DDR5 288-pin slots running at 5600 MT/s for a maximum of 2 TB registered memory.

Expansion and networking layout

Four PCIe 5.0 x16 slots with CXL 1.1 support plus two MCIO connectors at PCIe 5.0 x8 serve accelerator or storage cards. A third MCIO connector offers PCIe 3.0 x4 or four SATA 6.0 Gb/s lanes. Dual 10 GbE ports use Broadcom BCM57416 and a separate Intel I210 provides 1 GbE management.

DDR5 registered memory requirement

Only DDR5 RDIMM or RDIMM-3DS modules are supported; unbuffered or older DDR generations will not work. Builders needing unregistered memory or a different memory standard must choose another platform.

Questions about this item

How do I install a processor into the LGA 4677 socket without bending pins?

Align the CPU triangle marker with the socket corner, lower the load plate gently, then secure the lever evenly — uneven pressure is the step most often done wrong.

What maintenance will the DDR5 RDIMM memory slots need over time?

Reseat modules if ECC errors appear after thermal cycles; the 288-pin contacts can oxidise in humid racks.

Which limit appears first when all four PCIe 5.0 x16 slots run sustained workloads?

The single-socket CPU lane budget saturates before the board’s four x16 slots can each keep full bandwidth.
